Thank you Roy and Paul for your replies .

The plan is to move back into a motorhome. Weather this actually 
eventuates or not depends upon finding a buyer for our house. No doubt 
any buyer will not be interested in my current extensive station.

Anyway, I'm just exploring far simpler station options at the moment.

Actually the PL tone on AO-85 just turns the repeater on. Once it's on, there's no tone required until it times out...that's why you hear the noise on the uplink.

AO-85 and Fox-1B/Cliff/D will start the transmitter "hang timer" when
they detect the CTCSS.  The tone must be again detected within 60
seconds in order to reset the hang timer else the downlink transmission
will stop.  By having your tone on your uplink signal all the time, each
time someone keys it resets the hang timer.

I stand corrected on that... and better educated. (Also helps me understand the way the transponder has acted at various times that didn't previously make sense to me.) I supposed it could be desense or some other reason that you don't hear yourself then, but hopefully understanding that you are HEARING it will move you down the road to figuring it out and making contacts. =^)

The other strange thing that I realized is the behavior shown in the 2nd
video is with the rig operating with it's sub receiver running. If I
understand the TS-2000's architecture, those are 2 completely separate
receivers, that are both showing the same problem.

If you enjoy the roar of a rocket in the morning there will be streaming 
video of the United Launch Alliance Atlas 5 rocket flight to deploy the 
NROL-79 payload for the National Reconnaissance Office.  Coverage begins 
at 1730 UTC on http://spaceflightnow.com/2017/02/27/av068_journal/   
Launch is planned for 1750 UTC. No amateur radio payload on this flight

Sounds like there's no audio, or the volume somewhere in the audio chain
is turned all the way down.  Or the audio cable is broken (especially a
missing ground or ground loop).  That's the sort of display I see with
fldigi when I disconnect the audio cable from the PC.  Think "digital hum."

Thanks, Greg.  I should have said that the bear claw is what I am seeing on my panadapter from the satellite, not from FLDIGI

Sounds like there's no audio, or the volume somewhere in the audio chain is turned all the way down.  Or the audio cable is broken (especially a missing ground or ground loop).  That's the sort of display I see with fldigi when I disconnect the audio cable from the PC.  Think "digital hum."

SAT Grid Chasers,

I've pretty much finished the Winter visit with my Daughter
& Family in SE TX. The SAT Eqpt is mostly packed up for the
next leg of the trip to visit my Brother in FL.

>From 2/12-2/25, the results of my activity are as follows:
 - Operations = 22
 - Sat's = 5  FO29-SO50-XW2F-XW2C-AO7
 - Grids = 7  EL28/29/39 EM20/21/30/31
 - QSO's = 171
 - Unique Calls = 67
 - DX Countries = 6  (+ 3 Water Grids)

I'll be here in EM20vg through 3/4 in case someone has a desperate
need for EL39 or EM20 (!) before I leave, i.e. NEW ONE! Otherwise,
my next stop will be overnight in Biloxi, MS, EM50 on 3/5, then
Live Oak, FL, EM80 on 3/6. We get to Venice, FL, EL87 for a couple
weeks starting 3/7.

If you're going to use the earth's magnetic field to change orbit, you
want a linear force, not a torque as you'd use for attitude control.

A straight conductor will experience a Lorentz force perpendicular to
both the current flow and the ambient magnetic field. Problem is, how do
you close the circuit to keep the current flowing? If you run a second
conductor through the same magnetic field, it will experience an equal
and opposite Lorentz force. If it's physically separated from the first
conductor (i.e. forming a loop), the result will be a net torque, not a
net linear force.

So you need one of two things. Option #1 is a gradient in the magnetic
field. If your "forward" conductor is in a stronger part of the field,
it will experience a greater Lorentz force for a given current than the
"return" conductor in a weaker part of the field. You'll then get a net
linear force, along with plenty of torque.

The other possibility is to use something not attached to your
spacecraft as the return conductor so you won't feel the opposing
Lorentz force. But what conductor is there in space??

LEO is actually within the ionosphere, and that's your return path. This
is in fact how tethers have been used so far to either add or remove
energy from a satellite orbit.

Some years ago N6NKF and I looked at how much linear force you could get
from a practical magnetorquer coil. (I think it was when Oscar 13 was
decaying, so that was 20 years ago!) I don't remember the exact result
but I do remember it being negligible.

Here's a wild idea I just had. I wonder if it would be practical to
build an ion thruster for use in the ionosphere that uses the ambient
ions as your reaction mass? Think of it as vaguely analogous to the
Bussard Ramjet in science fiction. You'd collect both protons and
electrons and accelerate the protons rearward and the electrons forward
to maintain charge balance. The protons, being much more massive, would
result in a net forward thrust. You could also see this as analogous to
an airplane, only the "propellers" are electric fields that work on an
ambient atmosphere that is ionized.

Subject: [amsat-bb] Solid State conversion (tube equivalents)? END
Message-ID: <b107d16ba2c72c7c06f5530354dac0b4@mail.gmail.com>

Here is the conclusion to this thread with great feedback from James
Duffey and Diane Bruce...

> I picked up an old boatanchor LM-21 Frequency Meter at a Hamfest over
the weekend.  I original asked people here about converting the 3 tubes to
solid state.  But they said, why bother.  Just use it with the tubes...
and were curious how well it was calibrated now compared to its 85 year
old design age (1930's)?

So today I just powered it up with the tubes and it was within 150 Hz at 2
MHz after not being used since 1976.  Not bad.  In fact when I first
compared it to the modern sig gen, I thought it wasn't even working
because the 150 Hz was so close to zero beat I didn't hear it at first
until I dithered the dial!

I have no idea why I am doing this, but it sure brings back the good ole
days...

... why bother converting to solid state? The LM/BC-221 frequency meters
are, as you note,  very nice frequency meters/sources. They don't drift
when warmed up and are very solid mechanically. They age well and you are
likely to have performance now very close to what they were new.

If you insist on converting it to solid state, here is one article
describing how:
< http://www.hanssummers.com/images/stories/bc221t/bc221.pdf >
< http://hanssummers.com/bc221t.html >

including schematics and the manual.

But I doubt performance will be substantially better, if any, than the
tube unit you start out with.

Enjoy it. Technologically it is a wonderful thing to have just the way it
is. It is still a very useful laboratory quality instrument.  - Duffey

Right.

The Holy Grail of space travel seems to be propulsion with energy but no
propellant mass, at least propellant mass you have to carry with you.

You can make as much energy as you want from solar panels if you're
patient. Or use a nuclear reactor if you're less than patient, but
ultimately energy in space is nearly unlimited.

Mass is the big problem, because by definition space contains very
little of it (if any). So if there *is* any mass around you, however,
small, you should try to figure out a way to use it.

I also think about all the mass that's sent to the ISS only to be
wasted: upper stages of launch vehicles, complete cargo vessels, etc.
This waste won't get us to the planets. Everything sent into space
should be (re)used as many times as possible. Cargo ships and even spent
rocket stages should become permanent additions to the station, for
storage if nothing else.

Even trash could be used as reaction mass to reboost the station's orbit
if you can figure out how to accelerate it. A big electromagnetic
slingshot running the length of the station, for example.

We could have probably built a maglev space elevator in less time and for less money than Constellation/Orion spacecraft. The recurring cost savings of not launching "dead weight" would have paid for  the whole thing over time.

Right.

The Holy Grail of space travel seems to be propulsion with energy but no
propellant mass, at least propellant mass you have to carry with you.

You can make as much energy as you want from solar panels if you're
patient. Or use a nuclear reactor if you're less than patient, but
ultimately energy in space is nearly unlimited.

Mass is the big problem, because by definition space contains very
little of it (if any). So if there *is* any mass around you, however,
small, you should try to figure out a way to use it.

I also think about all the mass that's sent to the ISS only to be
wasted: upper stages of launch vehicles, complete cargo vessels, etc.
This waste won't get us to the planets. Everything sent into space
should be (re)used as many times as possible. Cargo ships and even spent
rocket stages should become permanent additions to the station, for
storage if nothing else.

Even trash could be used as reaction mass to reboost the station's orbit
if you can figure out how to accelerate it. A big electromagnetic
slingshot running the length of the station, for example.

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.  

For proposal information and more  details such as expectations, proposal 
guidelines and proposal form, and dates  and times of Information Sessions go

I saw his "bear claw" trace.  It appears to be a carrier and 3+/-
sidebands every 360 Hz or so.  I suspect this is some other modulation
method that uses 7 subcariers.  bob

Hi All 

I'm setting up an autonomous sat gate using a spare Kenwood TMD700. I seem to remember that once upon a time there was a DOS program called APRStk that could Doppler correct the TMD700. 

Does anyone know of a more up to date alternative that would run on a Pi or Pi Zero?

Message-ID: <5325febaa8220c217fc7b8a782ff329d@mail.gmail.com>

One thing to remember is that you cannot use normal Doppler correcting
software that tunes the radio.  The instantaneous radio steps cause Phase
discontinuities and that completely destroys PSK31.



The only ways to work well is to only try to decode when the bird is coming
right at you or right aways from you and the Doppler is not rapidly
changing.



*** OR *** use the special PSK31 Doppler uplink correcting program written
by Andy Flowers found on the PSAT web page? http://aprs.org/psat.html



Here is his page:

http://www.frontiernet.net/~aflowers/dopplerpsk/dopplerpsk.html



This software also allows you to run full duplex so that you can uplink
continuously throughtout the pass and independently receive all downlinks
at the same time.  The radio does not tune, but your uplink audio
compensates for the uplink Doppler so that your trace in the downlink
appears constant to everyone.



Yes, you can run UHF Radio stepped Doppler correction that steps down in
the usual 5 KHz steps 4 times during the pass.  You may still loose an
instant of phase corrupted characters, but only 4 times, not every few
seconds as the SSB radio would try to do if the computer program was trying
to compensate the SSB uplink radio.



That help?

Bob

Hey Dave.

It takes longer to read the instructions that it does to setup a Raspberry 
Pi to be an iGate.

When the ISS digipeater changed to 70cm, there were not enough iGates so I 
thought it might be fun to throw one together.  There are numerous how-to's 
online, but this one is perhaps the most straight-forward:

https://github.com/wb2osz/direwolf/blob/master/doc/Raspberry-Pi-SDR-IGate.pdf

... unfortunately, the way the document was created you won't be able to 
copy/paste commands.  But regardless, it's not a difficult process if you 
have even the slightest familiarity with a Pi or linux in general.

Hope that helps!

Hi All

I'm setting up an autonomous sat gate using a spare Kenwood TMD700. I seem 
to remember that once upon a time there was a DOS program called APRStk that 
could Doppler correct the TMD700.

Does anyone know of a more up to date alternative that would run on a Pi or 
Pi Zero?

I wonder how hard it would be to get the raspberry pi to download TLE's
every now and then, and apply doppler correction to the downlink iGate
frequency. on 70cm, this might be a big deal.

I was also concerned about that at first but on most passes I log a significant number of packet receptions, so while adjusting for RX doppler might help to some degree, it?s definitely not a deal-breaker.

(I also learned not to judge your effectiveness by the number of packets you iGate to ariss.net; it appears that duplicates only show up once.  So, to REALLY know how well you?re doing, check the log file on the iGate or use an external app to monitor it on another PC)

I just updated the http://aprs.org/psat.html web page to clarify how PSK31
uplink and downlink should be approached.  We should have done that a year
ago!

One thing to remember is that you cannot use normal Doppler correcting
software that tunes the radio.  The instantaneous radio steps cause Phase
discontinuities and that completely destroys PSK31.



The only ways to work well is to only try to decode when the bird is coming
right at you or right aways from you and the Doppler is not rapidly
changing.



*** OR *** use the special PSK31 Doppler uplink correcting program written
by Andy Flowers found on the PSAT web page? http://aprs.org/psat.html



Here is his page:

http://www.frontiernet.net/~aflowers/dopplerpsk/dopplerpsk.html



This software also allows you to run full duplex so that you can uplink
continuously throughtout the pass and independently receive all downlinks
at the same time.  The radio does not tune, but your uplink audio
compensates for the uplink Doppler so that your trace in the downlink
appears constant to everyone.



Yes, you can run UHF Radio stepped Doppler correction that steps down in
the usual 5 KHz steps 4 times during the pass.  You may still loose an
instant of phase corrupted characters, but only 4 times, not every few
seconds as the SSB radio would try to do if the computer program was trying
to compensate the SSB uplink radio.



That help?

Thanks for the replies on and off the list, 

The igate side of things is taken care of using a WX 3in1 APRS black box, I was hoping to be able to steer the D700 using something like APRStk for doppler but also to switch between sats PSAT etc

I wonder if it would be best to run 2 RTL's on a Rpi for use on both 144.39
and on UHF for the ISS, or is it just as effective to run one.

The only way that I am aware of to cover two different frequency?s APRS traffic on the same Pi would be to run two separate SDR?s under two different running programs.

This should not be a problem since the command string very specifically defines not only the SDR device being used, but also the frequency to tune and what config file to use settings from.

For example, here is my 70cm ISS iGate command string:

====================================
rtl_fm -f 437.550M -d 0 -s 48k - | direwolf -l /home/pi/igate/iss-uhf-log/ -c /home/pi/igate/iss.conf  -r 48000 -D 1 -
====================================

... please note the ?-d 0? argument after the ?rtl_fm? command.  That specifies SDR device #0, which is my case also happens to be the ONLY SDR attached to that particular Pi.  You can also plainly see the frequency and other settings.

I honestly can?t recall if I have tested it or not, but to run another iGate session with a second SDR, you would run a similar command except to tune a different frequency, specify a different SDR device, and use a different .conf file for your direwolf settings.  Most people would want to specify a different log file as well.

I wonder if it would be best to run 2 RTL's on a Rpi for use on both 144.39 and on UHF for the ISS, or is it just as effective to run one.

  (I also learned not to judge your effectiveness by the number of packets you iGate to ariss.net; it appears that duplicates only show up once.  So, to REALLY know how well you?re doing, check the log file on the iGate or use an external app to monitor it on another PC)

  I wonder how hard it would be to get the raspberry pi to download TLE's every now and then, and apply doppler correction to the downlink iGate frequency. on 70cm, this might be a big deal.

    Hey Dave.

    It takes longer to read the instructions that it does to setup a Raspberry Pi to be an iGate.

    When the ISS digipeater changed to 70cm, there were not enough iGates so I thought it might be fun to throw one together.  There are numerous how-to's online, but this one is perhaps the most straight-forward:

    https://github.com/wb2osz/direwolf/blob/master/doc/Raspberry-Pi-SDR-IGate.pdf

    ... unfortunately, the way the document was created you won't be able to copy/paste commands.  But regardless, it's not a difficult process if you have even the slightest familiarity with a Pi or linux in general.

    Hope that helps!

    Hi All

    I'm setting up an autonomous sat gate using a spare Kenwood TMD700. I seem to remember that once upon a time there was a DOS program called APRStk that could Doppler correct the TMD700.

    Does anyone know of a more up to date alternative that would run on a Pi or Pi Zero?

Message-ID: <f0c6a068-d31e-006f-df4f-6d2ed0e893b9@gmail.com>

Hi folks,

Has anyone used an RTL-SDR dongle on the 10.7 MHz IF output from another
receiver?  Is that better than going direct?

My cable TV provider is forcing us to go all-digital.  With the new
"cable box" comes the opportunity to re-wire the shack and simplify the
many layers of cables, splitters, and lash-ups that have accumulated
over the years.  The proverbial camel is crying out for help.

What this has to do with Ham Radio is that part of the lash-up mess is
an old pre-CATV deep fringe TV antenna that I have in the attic, aimed
to the southern horizon.  We are well outside the range of any of the
digital OTA stations, and never one to leave a perfectly good piece of
RF equipment go to waste, I currently have it fed to an old Icom R-7000
scanning receiver (previously used as the AO-40 downlink IF) and to an
RTL-SDR dongle by way of a TV 2:1 splitter.  I've tried hooking the
dongle directly to my 2m ham antenna for satellite use, but for some
reason that was less than satisfactory.  Never really did hear much of
anything, and never could figure out why.  At least with the TV antenna,
I can copy some stuff with the dongle, though the Icom is generally
better.  But the Icom doesn't do the various digital modes that are
better suited for SDR.

Looking at the back of the Icom, I see that it has a 10.7 MHz IF output,
so the thought is that the SDR dongle might perform better hooked there
(with a DC bias block) instead of to the antenna itself through the
splitter.  Both receivers have similar frequency coverage, but perhaps
the Icom, while somewhat deaf by modern standards, might still make for
a better front-end to the dongle?

I think the down-side is that the Icom's IF bandpass is narrower than
the Dongle's, so I'd lose some flexibility there.  I would also lose the
ability to software-control the frequency of the receive chain, outside
of the IF bandpass.

What do you think?  Would this be a net win or loss for the RTL-SDR?

Thanks,

Greg  KO6TH

I would hope (but perhaps not assume) that your R-7000's front-end is
better than the silicon tuner within the RTL dongle. The IF will already
have AGC applied to it, so overload of the dongle won't be a concern
once you get the level from the IF tap down to something that doesn't
over-range the dongle's AGC input on typical signals. That can be done
with a simple inline attenuator.

Here's some information about a hardware mod which allows "direct
sampling mode" on the dongle:

http://www.rtl-sdr.com/rtl-sdr-direct-sampling-mode/

By doing this, you are essentially creating a Panadapter for the R-7000.

Let us know how it works!

I tried to add the info from that Since I use the Nasabare element set, but it's not working and the frequency is not showing. Can someone post the proper edit for both names?

FINALLY!  I am not losing my mind.

Fer sees the same thing that I see on receive!  Multiple harmonics signals in the passband on RX!  Is that what it is supposed to look like?  I am expecting a single PSK31 trace like what I see on HF?.how will multiple harmonics be decoded sing FLDIGI?  Sorry if I am wrong about this, but that?s what an overmodulated AFSK BPSK signal looks like on HF.

I just caught the word ?beacon? and a partial call on the 0330 pass.

I think I saw my downlink when I was transmitting?there was about a 2-3 second delay after I started to transmit, but when I stopped transmit the downlink signal ended almost immediately.  This happened twice, so I think I was getting through the bird.

OK, I will try something different next time.  I will decode/receive using my IC-910H instead of the SDRPlay RSP1 receiver.

I don't think an RTL dongle will tune down that low.

Doh!

Well, that answers that question.  Thanks, Jim.  You are correct!  24.00

Greg,

There are modified versions of the RTLSDR dongle that support
direct sampling.  That is to say, a signal is fed directly into the
RTL2832 chip, bypassing the tuner/down-converter chip.  This
enables reception of signals from 0 to 14.4 MHz (half the
28.8 Msps sampling rate of the analog-to-digital converter).
Perhaps you could make use of one of these. Search for them
on Ebay or through Google in general.  You may need to
attenuate the 10.7 MHz IF signal prior to feeding into the
dongle, as too strong a signal will damage it.  Hope this helps.

73,

Mac / AE5PH

I don't know what your budget is, but an SDRPlay would work fine at those 
frequencies and is a higher performing SDR as well.

I know there are plans for simple upconverters out there, but I've never 
built one.


I've owned most of the SDR receivers out there, from $5 dongles to both 
FunCube dongles, the HackRF One, SDRplay, and now the AirSpy. Depending 
on what you want to use them for, and *where* you're located, they can 
be really cool, or a disappointment.


Here in the RF Alley of SoCal, the cheap dongles can really fold up on 
strong signals many, many MHz away from the signal-of-interest.

Thank you Arrow Antenna for just becoming a sponsor of Space Comms! I
still have my original Arrow II satellite antenna from 2000 and I
highly recommend them.

Thanks to Dog Park Software for the usage of MacDoppler and
MacLoggerDX, sorry for forgetting to include you in the end credits.

Thank you of course to Victor for doing the translation. It was a lot
of fun working with you. Thank you to Phillip Zucchino at The Wine
Feed for hooking me up with SKEMA, and Marie Claire at SKEMA for
hooking me up with Victor.

Thanks to Max, K2MAX for recently becoming a patron. Good luck working
satellites from the San Francisco bay area where you won't have many
obstructions on the horizon.

Thanks to Frank for the drone footage.

And thanks to you for watching!

73, John Brier KG4AKV

Hi All,

FUNcube-1 is now in amateur (continuous transponder) mode. The plan is to switch back to auto mode on Sunday 5th March 2017 pm UTC as usual.

See https://funcube.org.uk/news/ for the latest details of Nayif-1/EO88  and new updated Dashboards. Please also see below for details of all the FUNcube spacecraft.

Have FUN with the transponder!

73s Graham G3VZV and the FUNcube team.

++++++++++++++++++++++++++++++++++

FUNcube frequencies and other details

++++++++++++++++++++++++++++++++++



AO-73 FUNcube-1 



The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. 

  

When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) 

  

The nominal transponder frequencies are: 

Uplink:   435.150 - 435.130 MHz LSB (Inverting)  

Downlink:   145.950 - 145.970 MHz USB

Telemetry Tx: 145.935 MHz BPSK

(The passband may be up to 15kHz higher depending on on-board temps. Low temperatures give higher freqs!)



  

FUNcube-2 aka FUNcube on UKube



The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC).

  

The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). 



The nominal transponder frequencies are: 



Uplink:   435.080 - 435.060 MHz LSB (Inverting)  

Downlink:   145.930 - 145.950 MHz USB

Telemetry Tx: 145.915 MHz BPSK

(The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!)



 EO79 FUNcube-3



Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience.

  

The nominal transponder frequencies are:



Uplink: 435.0723-435.0473 MHz LSB (Inverting)  

Downlink: 145.946-145.971 MHz USB 



Further detailed info on EO79 transponder frequencies is at: 

 https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/



EO88 Nayif-1 FUNcube-5



EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, ie the solar panels are NOT being illuminated.  

When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power.   



The transponder frequencies are: 

Uplink:  435.045 ? 435.015 MHz LSB (inverting)

Downlink: 145.960-145.990 MHz USB

Telemetry  Tx: 145.940MHz



All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very grateful for the assistance given by Innovative Solution In Space Bv, The Netherlands.

 One thing to remember is that you cannot use normal Doppler correcting

The only ways to work well is to only try to decode when the bird is coming
right at you or right aways from you and the Doppler is not rapidly
changing.



*** OR *** use the special PSK31 Doppler uplink correcting program written
by Andy Flowers found on the PSAT web page? http://aprs.org/psat.html



Here is his page:

http://www.frontiernet.net/~aflowers/dopplerpsk/dopplerpsk.html



This software also allows you to run full duplex so that you can uplink
continuously throughtout the pass and independently receive all downlinks
at the same time.? The radio does not tune, but your uplink audio
compensates for the uplink Doppler so that your trace in the downlink
appears constant to everyone.



Yes, you can run UHF Radio stepped Doppler correction that steps down in
the usual 5 KHz steps 4 times during the pass.? You may still loose an
instant of phase corrupted characters, but only 4 times, not every few
seconds as the SSB radio would try to do if the computer program was trying
to compensate the SSB uplink radio.



That help?

Bob

On a positive note, APRS is working perfectly on NO84 even at low passes.

EO-80 and EO-88 have similar names. Simply based on that, seeing one
might remind you of the other.

Perhaps that wasn't it though...

Regardless, the answer to the original question is on amsat.org

"Additionally, the satellite carries a AMSAT-F constructed repeater as
a return favor for support of the use of the amateur bands for the
primary QB50 mission. Unfortunately the primary transceiver was
damaged during a test of the repeater, and the repeater is power
negative. Further activation of the repeater is unlikely at this
time."

OK, tonight on the high pass at 0300 UTC over US East Coast, I heard the following with my IC910H tuned to 435.350 MHz FM-Narrow, feeding FLDIGI through a SignaLink USB card:

1.      W3ADO beacon.  The beacon signal was so strong it was almost like hearing an FM repeater that is "full quieting" with no background noise at all.
2.      Someone transmitting early in the pass, but Doppler was moving the signal and I did not decode it because it eventually went right on top of the beacon.

I attempted to transmit using DopplerPSK, 50 watts to an inverted L, but I did not see my signal on the downlink at all.  I measured 50 watts output, and I listened on a separate receiver (no antenna) on 28.120 and I did hear PSK.

Questions:
*       I am using TS480SAT for transmit.  I have the dial on 28.120, which means that the center AF frequency is 2 kHz according to Doppler PSK.  Is that correct for the dial frequency?
*       Any other suggestions on what I should do, or just try again on the next pass?

EO-80 and EO-88 have similar names. Simply based on that, seeing one
might remind you of the other.

Perhaps that wasn't it though...

Regardless, the answer to the original question is on amsat.org

"Additionally, the satellite carries a AMSAT-F constructed repeater as
a return favor for support of the use of the amateur bands for the
primary QB50 mission. Unfortunately the primary transceiver was
damaged during a test of the repeater, and the repeater is power
negative. Further activation of the repeater is unlikely at this
time."

Has anyone used the Yaesu FT847 full duplex on the satellites with a
dualband antenna and a diplexer?  Is the isolation enough with a good

Doug,

Some users do quite well with the eggbeater setup
I started out with the UHF & VHF eggbeater setup with preamps and iC910. It worked OK for the FM birds, but I found it lacking when it came to the sideband birds. I didn't go big, I now use a rotor with dual Arrow antennas. The most important part for me was to purchase preamps with built in band filtering.

David,

SatPC32 includes a utility for backup and restore.  Use it, as there are
about 150 files spread across several directories.

Run SatPC32, go to the Programs menu, then click on DataBackup.  Press the
Save button to make your backup.  Press the Restore button to copy all of
your files and settings into a new install of SatPC32.

I am in the process of making my own set of DIY eggbeater's, so I am glad
to see some people have a little sucess with them. What preamps did you
use? Do you know of a good way to add a band-pass filter to the front of a
wideband preamp like the LNA4All?

Doug,

I purchased the preamp from SSB-electronic.com. 
Yes, there are ways to DIY your own filter, maybe someone can chime in with a link.

You will do just fine with eggbeater antennas for LEOs.  You won't get
horizon-to-horizon coverage as these are not gain antennas, and they shift
to horizontal polarization on the horizon, so are subject to more fading on
the horizon.  But you will get at least six minutes of a 10 minute pass,
and possibly more.  If that is adequate depends on your operating criteria:
 If you want to work all states and get every minute of possible QSO time,
you are going to need a pretty fancy steerable antenna array that will set
you back 5x the amount of money that the omni antennas will cost.

Putting the eggbeater up at height on a tower will probably buy you nothing
but feedline loss unless you need it that high to have a reasonable clear
horizon.  I mounted mine a couple of feet above the peak of the roof.

Depending on your coax length, putting a mast mounted preamp on them might
be useful.  With 60 feet of feedline I'd personally install mast mounted
preamps, but you might have to turn the gain down a bit.

I installed M2 eggbeaters in 1998.  Been working flawlessly for almost two
decades and they have survived several hurricanes and New England Winters.

It really comes down to how much complexity you want, how much expense, and
how much service time you want to expend vs your operating criteria. I
seriously doubt a full set of CP beams and rotor would still be working
after 20 years in my environment.

Frank Bauer, KA3HDO, 2017 Dayton Hamvention Amateur of the Year

The Dayton Hamvention has announced the winners of the 2017
Hamvention Awards. Each year, the Dayton Hamvention honors radio
amateurs who have made major contributions to the art and science of
amateur radio. AMSAT Vice President for Human Spaceflight Frank
Bauer, KA3HDO, was named 2017 Amateur of the Year.

The award citation reads:

?Frank serves as the Amateur Radio on the International Space
Station (ARISS) international chairman. In the mid-1990s, Bauer
proposed a GPS reception experiment on the AMSAT Phase 3D satellite
(AO-40). The experiment was to measure the signal strength of the GPS
satellite constellation while Phase 3D was in high-Earth orbit (HEO).
The AO-40 experiment subsequently has been cited often in aerospace
literature, as it remained the most comprehensive above-the-
constellation data source for nearly a decade and led to changes in
the system?s specifications and applications. The results of the AO-
40 experiment jump started a game-changing transformation in
navigation at HEO/GEO altitudes, enabling new and exciting missions
in these orbits.

Bauer holds bachelor?s and master?s degrees in aeronautics and
astronautics from Purdue University. His career in aerospace spans 4
decades within NASA and in private industry

Bauer has been licensed since 1974. In 1983, in preparation for the
space mission of Owen Garriott, W5LFL, he was responsible for setting
up and operating the worldwide retransmission of Space Shuttle air-to-
ground communications from Goddard Amateur Radio Club station WA3NAN.
This initiative provided a critical conduit of information to hams
attempting to contact astronaut-hams in the pre-Internet era.?

Ham radio satellite activation of Berry Islands, Bahamas

Steve M1ACB, Rob M0VFC and John M0IDA will be active on the FM and
SSB amateur radio satellites from Berry Islands in the Bahamas.

The trio plan to operate from March 4-10 and will be using hand-held
antennas. Since the FM satellites will only cover part of the USA
they?ll also be using SSB on FO-29 to reach the British Isles and
Europe.

They will be operating from Little Harbour Cay in the Berry Islands,
IOTA NA-054, Grid Square FL15do.

NASA Explores Opportunity for Smaller Experiments to 'Hitch a Ride'
to Mars

NASA's goals for human deep space exploration are complex and
ambitious. To maximize resources as it pushes the boundaries
of exploration, the agency is exploring opportunities to take
advantage of emerging private sector space capabilities.

NASA released a request for information Monday regarding possible
commercial sources to fly limited payloads on planned, non-NASA
missions to Mars. The agency will use the responses to gather
market data on the complete spectrum of commercial plans, and
identify any excess capacity that may exist for NASA payloads.

Furthering NASA's human deep space exploration goals will require
a significant amount of scientific research, and opportunities to
collect data on Mars have been rare. Only seven successful missions
to the surface of Mars have taken place in the history of space
flight.

Evolving capabilities in the private sector have opened the
possibility for NASA to take advantage of commercial opportunities
to land scientific payloads on the surface of the Red Planet. Such
capability would provide an additional method of acquiring science
and engineering data concerning Mars, and would complement NASA's
current deep space exploration efforts.

Belize on Satellite

Good evening to my fellow people of the birds,

The time has come. I will be venturing to the land of Belize March
11-19 and will be on the satellites with the call V31NJ. I will
operate from various grids and possibly some islands (a side trip to
Roatan, Honduras is possible with operations from there, not positive
yet). This is gonna be a vacation style op (going with my little
brother for his spring break), so don't expect me on every pass.

If I can get a permit for Guatemala TG/NJ7H may also be on a few
passes, though I'm not sure if from any grids different than in
Belize.

QSLing will be via LoTW. If there is a demand, I can get some cards
printed when I'm back.

Nayif-1 Status Report and New Dashboard

The Nayif-1 (EO-88) CubeSat has now been in orbit for more than two
weeks and all systems continue to operate nominally.

The power budget is positive, the spin/tumble rate is acceptably
low, on board temperatures are perfectly okay and, importantly, the
educational/amateur transponder switching is taking place
autonomously as  planned.

More than 250 stations around the world have provided telemetry to
the Nayif Data Warehouse and the FUNcube Team are extremely grateful
to them for their invaluable support.

The experts have now formally allocated Catalog Number 42017 to
Nayif-1 (EO88) and the TLEs can now be downloaded from Celestrak ?
TLEs

New Dashboards

The FUNcube Team have now updated the Dashboards for both Nayif-1
and FUNcube-1 so that they display only the telemetry received from
the individual spacecraft that they are designed for. This will help
users to display only the correct information and graphs and reduce
confusion. Whilst they only display the data from ONE spacecraft,
they will, as now, receive and decode the data from all FUNcube
payloads currently in orbit and automatically submit it to the
relevant Data Warehouse.

The new Dashboard for FUNcube-1 (ver 1044) can be downloaded from
here: FUNcube Dashboard Installer 1044

The new Dashboard for Nayif-1 (ver 1040) can be downloaded from
here: Nayif-1 Dashboard Installer 1040

Additionally some command line parameters have been added to enable
the programmes to auto-start with the desired parameters.  These are:

/minimized
/autostart
/source=dongle
or
/source=soundcard

Some notes on how to implement these parameters can be found here:

Hi,

At the moment, it is not expected that the satellite control team will do this.
The satellite is controlled from the American University of Sharjah in
the UAE, and it is unlikely that the staff and students will be
around, unless a contingency arises which needs immediate action.

Also note the weekend over there is Friday and Saturday, and Sunday is
a workday.

OK,

 

I've edited the AMSAT names file as Alan indicated, restarted the program
and still it is not showing the frequencies.

 

Here is what I have in the files:

 

AMSAT names:

 

42017 17008XX  Nayif-1

42017 17008BX  EO-88

 

Doppler:

 

NAYIF-1,145975,435030,USB,LSB,REV,0,0,CW/SSB Transponder

EO-88,145975,435030,USB,LSB,REV,0,0,CW/SSB Transponder

 

Now, I figure this works for all the other birds but not this one. Any ideas
would be appreciated>

Rick,

Capitalization is important in this case.  NAYIF-1 doesn?t match Nayif-1.
You need to edit the DOPPLER.SQF file to spell Nayif with upper and lower
case letters.  Ask me how I know that.  ;-)

Message-ID: <CO2PR06MB49141279528AB8B0C70B5B1952C0@CO2PR06MB491.namprd06.prod.outlook.com>

Making some progress....0335 UTC pass, I decoded the PSK31 beacon AND decoded W5SAT calling CQ.

However, I failed to see my signal on the downlink again.  I am using 65 watts and an inverted L for 160 that tunes for 10 meters.  The thing should be working, I worked several EU stations on 40 meters with just 5 watts tonight, so it's radiating SOMETHING.

I am sending PSK31 with DopplerPSK and then trying with FLDIGI, so it's not the software.

I am getting power out per the wattmeter, so it's not the transmit setup.  EZNEC shows a mostly cloud-warmer type of pattern for the inverted L on 10 meters, with some small gain at lower angles.

Maybe I will try the off-center-fed dipole next.  What are other folks using for antennas on the uplink?

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.  

For proposal information and more  details such as expectations, proposal 
guidelines and proposal form, and dates  and times of Information Sessions go 
to  http://www.arrl.org/hosting-an-ariss-contact.  
Please direct any  questions to  ariss at arrl.org.

Steve,

 

I know how you know... That did the trick.  I knew it would be something glaringly obvious.

 

Thanks for pointing it out..

Rick,

 

Capitalization is important in this case.  NAYIF-1 doesn?t match Nayif-1.

You need to edit the DOPPLER.SQF file to spell Nayif with upper and lower case letters.  Ask me how I know that.  ;-)

Mark,

 

Yep - that was me calling CQ tonight.  My first time trying PSK31 on NO-84.
I read your posts on the subject and it sounds like you are doing everything
right.

 

I was able to consistently seem myself when running 50 watts throughout the
pass and as low as 20 watts when the satellite was overhead.  Any less and I
couldn't make the round trip and decode myself.  

 

I mostly used a Zero-Five 10-40 ground plane vertical (27 feet) but I was
also able to make the trip with a G5RV Jr. antenna about 15 feet above
ground.  I might try the G5RV Jr. for the full pass next time since that is
a cloud warmer for sure at that height.

 

I am using a TS-2000 for both TX and receive.

 

I assume you are 28.120 Mhz USB on your uplink (never hurts to check) and
have configured DopplerPSK with your location and put fresh elements in the
tle folder where DopplerPSK is.

 

I noticed it took a few seconds to activate the transponder when I started
transmitting.

 

Well, that's all I have to offer at this point since today was my first try
using this mode.

 

Thanks,

 

Brad Schumacher

I see there are quite a few Chinese 25 watt dualband mobile FM rigs out
there today at great prices, like under $100.  Jetstream, Leixen and quite
a few other brands are out there.  Has anyone tried these on the FM
satellites, and if so, how do they work?

Tonight, I am pretty sure I saw my downlink signal.  Unfortunately it was very weak using the off-center-fed dipole transmit antenna.  And...there was a Doppler shift even though I was using DopplerPSK for transmit.  The signal did start and stop as I started and stopped DopplerPSK transmit, so I am pretty confident I am seeing my transmission.

Maybe a true ? whip is needed for transmit...

Subject: NO-84 - the investigation continues


Making some progress....0335 UTC pass, I decoded the PSK31 beacon AND decoded W5SAT calling CQ.

However, I failed to see my signal on the downlink again.  I am using 65 watts and an inverted L for 160 that tunes for 10 meters.  The thing should be working, I worked several EU stations on 40 meters with just 5 watts tonight, so it's radiating SOMETHING.

I am sending PSK31 with DopplerPSK and then trying with FLDIGI, so it's not the software.

I am getting power out per the wattmeter, so it's not the transmit setup.  EZNEC shows a mostly cloud-warmer type of pattern for the inverted L on 10 meters, with some small gain at lower angles.

Maybe I will try the off-center-fed dipole next.  What are other folks using for antennas on the uplink?

Subject: [amsat-bb] Upcoming ARISS contact with Blair Pointe Upper
	Elementary School, Peru, IN
Message-ID: <BC4A2167213F4B10BC340E178C128661@DHJ>

An International Space Station school contact has been planned with participants at Blair Pointe Upper Elementary School, Peru, IN on 09 Mar. The event is scheduled to begin at approximately 15:21 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and WD9GIU. The contact should be audible over the state of Indiana and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English.

 

 

Blair Pointe Elementary School is in small town, Peru, IN. It is a town that is about 70 miles north of Indianapolis, and is in the same county as Grissom Air Reserve Base. It is a school that houses third through sixth graders. Blair Pointe is part of the Peru Community School Corporation that has

approximately 2,150 students in all 5 of its buildings. Our school has a diverse population with students coming from rural areas, apartments, mobile home parks, and low and middle income homes.

 

As a school, we provide many opportunities outside of the classroom to learn. A very high population of our students attend our various after school programs such as our remediation program, choir, art club, and robotics. We also have a high focus on the fine arts and through this we are able to provide a lot of learning across subject areas. This year we were able to bring in astronaut Jerry Ross to speak with our students about his space career. In addition, we have a very strong sports program including baseball, soccer, football, track, golf, cross country, wrestling, basketball, tennis, and volleyball.

 

 

Participants will ask as many of the following questions as time allows:

 

1. Why and when did you become an astronaut?

2. How many people work on the space station at one time? And why?

3. What is your job on the space station?

4. What do you do when someone gets sick while on the space station?

5. Has anyone ever broken a bone on the space station? Do bones break 

   differently in space?

6. What kind of experiments do you do in space and are they safe or 

   dangerous?

7. What happens if something in space hits the space station and damages the 

   ship? How would you fix it?

8. How do you keep track of all the floating debris?

9. Do the other astronauts sometimes get on your nerves?

 

10. How does it feel to be away from your family?

11. We all know astronauts have months of training, but has there been one 

    thing you were not ready for in your experience?

12. What is a day like on the ISS? What do you do every day?

13. When you are going into space and start feeling less gravity, do you feel 

    light-headed or nauseous? If so, is there anything in your training to 

    prepare you for this?

14. If your space suit gets torn, how would you fix it, and has it ever 

    happened to you before?

15. Do you ever get hot or cold in space and is there air conditioning on the 

    ISS?

16. Is there wifi in space?

17. Are you ever scared that you might run out of oxygen or that your ship 

    goes away from the Milky Way

    galaxy?

18. Have you ever become unhooked from the space station? What does it feel 

    like to be floating around in space?

19. Is time in space different from time on Earth?

Subject: [amsat-bb] Upcoming ARISS contact with 3rd Junior High School,
	Komotini, Greece
Message-ID: <4F8DB5AA78A8434393807E2CC8C8B7AF@DHJ>

An International Space Station school contact has been planned with participants at 3rd Junior High School, Komotini, Greece on 10 Mar. The event is scheduled to begin at approximately 08:20 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between OR4ISS and SV7APQ. The contact should be audible over Greece and adjacent areas. Interested parties are invited to listen in on the 145.800 MHz downlink. The contact is expected to be conducted in English.

 

 

The 3rd Junior High School of Komotini is one of the 13 schools of Secondary Education that operate in Komotini, a city in the Region of Eastern Macedonia and Thrace, in the north-east of Greece. Our school is one of the oldest in the Municipality of Rodopi. The current building was constructed in 1992. Its a relatively new building with 16 classrooms, and laboratories for Computer Science, Physics, Chemistry, Biology, Music rooms, multiple-function rooms and a fully-equipped library. There are approximately 350 registered students (age 12-15), and 38 teachers of different fields in our school. One of the main characteristics of our school is its multi-cultural character. 25% percent of our students come from repatriated Greek families who lived for about a century in countries of the Former Soviet Union (Russia, Georgia, Armenia, Ukraine, etc) and came back to Greece in 1990 after the collapse of the regime in the countries of Eastern Europe. These students speak both the Greek and the Russian language fluently. 16% percent of our students are Muslims. The existence of a Greek Muslim minority in Thrace has been recognized internationally since 1922. Among them, there is a significant number of Pomaks and Roma students. There are integration classes for students with special educational needs and learning disabilities taught by teachers of Special Education. Additionally, every year many national educational programmes, such as Environmental Education, Health Education, Consumer Education and many Cultural programmes (music, dance, theatre, art, radio, astronomy) are implemented. Our school also has a very active cycling club. Students go on various educational trips every year, visiting other parts of Greece and expanding their learning skills and abilities.

 

 

Participants will ask as many of the following questions as time allows:

 

1. What is the most challenging problem of living in space?

2. Can you see the moon closer from Earth, is it different?

3. How do you stabilize the food on the table?

4. How often do you do extravehicular activity?

5. Is it very difficult to become an astronaut?

6. Do you have sufficient oxygen in ISS?

7. If you had just one wish to become true for your job what would it be?

8. If a member of the crew is injured can you give him first aid?

9. When you come back to earth, is it easy for you to walk?

10. Which is the difference between day and night in Earth and in Moon?

11. What is the main target of your expedition?

12. Can you see meteor showers from space?

13. Have you ever seen a comet from space?

14. How long did the preparation for this expedition last?

15. How many hours do you work, do you have shifts?

16. What is the most extreme procedure of your expedition?

17. What is your favorite food in space?

18. How old were you when you decided to become an astronaut and what was the 

    motive of your decision?

operate from Southhaven, MS for a for a bit. For sure passes schedule is as
follows:

2017-03-08 SO-50 0145UTC
2017-03-08 AO-73 0215UTC

If I make good time driving I *might* be on some of the XW's before 0100z,
and if there are huge piles and I can't get to everyone I *might* stick
around for Nayif and FO29 at the end, but plan on being there for those 3.

I'll be on APRS KG5CCI-5, and updates via Twitter @KG5CCI.

Hi,

The data collection server is back up again after several hours. It is now collecting data from dashboards which were pending.

I will be changing the runtime implementation during the day to make it more stable.

Apologies for the problem.

Message-ID: <00a601d297c6$e02b0440$a0810cc0$@gmail.com>

I was on the 0410 UTC NO-84 pass tonight and saw nobody else.

 

I was running 5 watts uplink for most of the pass and was able to decode cleanly except at the sub 20 deg elevations.

 

I tried both the 27? vertical and G5RV Jr. and they both seemed to do just fine even at my lowest power levels.

 

I lowered my uplink frequency to 28.119 Mhz and saw myself at 1250 Hz on the audio spectrum.

 

One change I made was to control my rotor and receive via SatPC32.  My Doppler.sqf looks like this:

 

NO-84,435350,28120,FM,USB,NOR,0,0,Wide FM

NO-84,435350,0,FMN,,,,Narrow FM

 

I use the first set to get the 28.120 close and manually tune to where I want it then switch to the second one which does not change the uplink Doppler ? just the downlink doppler. 

 

Ok, not sure if this helps but I am finding this setup to be very reliable and the satellite seems to have a great RX and very strong downlink.  An absolute pleasure to work with.

 

Thanks,

 

Brad Schumacher

?Hi!
This weekend - Friday and Saturday, 11-12 March 2017 - AMSAT will be part
of the booth for the University of Arizona Amateur Radio Club (K7UAZ) at
ScienceCity, a large science fair that will be held on the University of
Arizona campus in Tucson, Arizona.

ScienceCity is advertised as the largest STEM event in Arizona, and has a
lot of participation from different parts of the university and other
groups from Tucson and southern Arizona. There is also a book fair that
takes place at the same time in the same area, and these events usually
draw well over 60,000 visitors for each day. More information about
ScienceCity is available at:

http://sciencecity.arizona.edu/

The K7UAZ club will have an HF station operating at its booth during the
two-day event. In addition to this, I will have demonstrations of amateur
satellite operation using my portable equipment from somewhere near the
K7UAZ booth. At this moment, I think that the satellite operations will
be done using my WD9EWK call, but I could end up using K7UAZ as I did for
the satellite demonstrations last year. If you hear me on the satellites,
using either of these call signs, please call and be a part of the
demonstrations. If available, I hope to also try working the digipeaters
on the ISS and NO-84, along with the other satellites in FM and SSB. The
Tucson area is in grid DM42.

If I use WD9EWK for the demonstrations, I will upload my log to Logbook
of the World, and issue QSL cards on request (please e-mail me directly
with QSO details). If I operate as K7UAZ, I will provide the club with a
log, and any QSL requests would need to be sent to the address listed on
QRZ.com for K7UAZ with SASE. K7UAZ does not use LOTW at this time.

During the weekend, as I have done for the past two events, I will tweet
updates including pictures from the event, and when I plan on working
different satellite passes using my @WD9EWK Twitter account. If you do
not use Twitter but want to see these updates, please visit:

Thanks, and 73!

Subject: [amsat-bb] Antenna better when NOT pointing directly at TX source?
Message-ID: <CAJCSnOaQrf=MUfdpoRd8mCGQvusxiYWewA=i4-oG5c56k0BEYQ@mail.gmail.com>

Hello everyone.

While my question is not directly satellite related, I hope that it's a
general antenna question that might be of benefit for satellite reception
as well.

I have developed an interest in tracking the 400 MHz radiosonde
transmitters used by the (U.S.) National Weather Service office on the
other side of the state for their twice-daily weather balloon launches.
When the wind carries one anywhere in my general direction, it's a lot of
fun to try to receive & decode the position & altitude telemetry being sent
by the thing.  Maybe one day I'll even hit the road and track one down!

Anyway, my question is in regard to the pointing of my antenna, which is a
70cm X-Quad connected for RHCP.  The elevation is fixed at 45?.

I have confirmed that my antenna is pointing in the compass direction
indicated by the indoor control box.  The radiosonde is telling me via
telemetry what its location is.  From that, it's easy enough to plot on
Google Earth and see exactly what the compass heading is from my location
to the balloon at any given time.

The catch, even considering the ~ 10? declination at my location, is that
it's very common for me to receive a MUCH stronger signal with my antenna
pointing 45 or 90 degrees away from what should be the correct heading!  I
sweep back and forth and it varies... and also depends on how close the
balloon is to my location.  But for much of a flight, especially at greater
distance, it's quite common to receive a huge signal off-heading... where
if I point directly at the transmitter, it's barely out of the noise.

I don't know if this is a polarity issue, an issue caused by the
transmitter wildly swinging around under the balloon (much like a tumbling
satellite?), or an issue caused by the characteristics of my particular
antenna.

So that's my dilemma; I can't tell you anything about the TX side because
for this particular aspect of the hobby, I'm only concerned with
reception.  But is there any legitimate reason for me to be seeing these
massive differences in receive SNR when I am turned so far away from the
transmit source?  Anyone ever seen this in other situations?

Thanks!

I recall in the Mode K and A days, yagis tuned for the low end of 10m would often display very skewed patterns on 29.4 MHz.

Given your antenna is presumably tuned/designed for 435, it's pattern at 400 is likely very different.

Also, 45 degrees seems excessive for satellites unless you live in a hole, and certainly for balloons close to the horizon. I'd try 15-20 degrees.

Frank Bauer, KA3HDO 

2017 Dayton Amateur of the Year Winner

 

  

The Dayton Hamvention has selected ARISS International Chair, Frank Bauer, KA3HDO, for its top award, Amateur of the Year for 2017.  Each year, Hamvention recognizes radio amateurs known for making major contributions to the art and science of amateur radio, and it's no surprise why Bauer was chosen.  A few things from his lengthy list of achievements follow.

In 1995, Bauer proposed an experiment for the AMSAT Phase 3D satellite (AO-40) to measure the strength of the signal from the GPS satellite constellation. For years after, the aerospace industry cited this experiment because the results helped engineers improve the GPS system, led to new applications for GPS, and changed navigation at High-Earth Orbit (HEO) and Geosynchronous Orbit (GEO) altitudes, allowing new missions to operate in these orbits.

Prior to NASA astronaut Owen Garriott, W5LFL, flying in space and taking along ham radio in 1983, Bauer came up with a plan for, and helped set up and operate, the worldwide retransmission of space shuttle air-to-ground communications by the Goddard Amateur Radio Club station, WA3NAN (now K6DUE). Tens of thousands of hams enjoyed listening to most every shuttle mission's astronaut communications, and amateurs used these to help them make ham contacts with crewmembers who had their amateur licenses. Bauer's work with this system also let to his becoming part of the SAREX (Shuttle Amateur Radio EXperiment) team. 

Bauer attended Purdue University where he earned its prestigious bachelor's degree and master's degree in aeronautics and astronautics. This led to a long and full career with NASA followed by a move to the private aerospace industry. He earned his amateur radio license in 1974, and has been the AMSAT-NA Vice President for Human Spaceflight for many years.

What Bauer has spent, and now spends, the most time and energy on is the Amateur Radio on the International Space Station (ARISS) program. He helped set up the very first meeting of worldwide volunteers at NASA's behest in 1996, working as AMSAT's representative, alongside Rosalie White, K1STO as ARRL's representative. People from the world's AMSAT societies and IARU organizations answered their calls to attend the meeting at NASA Johnson Space center in Houston, and the rest is history--20 years of growing ARISS into how it is today...still growing!  

White wrote, "Frank didn't just think about where amateur radio in space should be; he always thought about where it was headed--he still does.  His multi-faceted background and experience in aerospace, NASA, and amateur radio is the ideal combination resulting in effectively spearheading the ARISS team in offering to hams, students, and the general public, ARISS success after ARISS success."  

Very hearty congratulations from the ARISS team to Frank Bauer, KA3HDO, on his new title, Dayton Hamvention 2017 Amateur of the Year!



About ARISS

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA).  The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues.  With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums.  Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.  For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.

I did and now all I get is a popup that says certain files while attempting to be loaded had errors and that program will be shut down.  It won't open to let me fix whatever I did wrong.

RFI.

The receiver is overloaded pointing near the source (and the rx
target). Farther to the side of the pattern, the signal to noise seen
by the receiver is better.

I set up 9 times in Suriname for mode B. Heard the satellite 3 times,
myself twice. Some interference on UHF, just enough to make 3 degrees
was my horizon. El sucko if you're trying to bag EU on FO-29.

Spent most of my free ish time troubleshooting this.

First checked the VHF cavity I brought. It was OK. Then the cables.
Then the antenna. Then swapped radios. Then tried something weird:

Normally the gear looks like this:
https://www.flickr.com/photos/n3ykf/30156921505/in/dateposted/

With nothing to lose, I tried setting the VHF antennas up like this.
The UHF antenna was, of course pointing downrange.

https://www.flickr.com/photos/n3ykf/30072301431/in/photostream/

The antenna pattern went from cardoid to cloverleaf. DEEP nulls at the
sides. Found an RFI  source in 5 minutes. Heard AO-7 mode B clearly
for most of the pass I set up for. EXCEPT where the antenna was
capturing more noise than signal.

There was an RFI source within 100' that was broadband and s9+. Point
away? Hear satellite. Point in the direction of the noise? Nothing.

The noise went down to 29MHz. Tried AO-7 mode A. Could hear the beacon
off of the rear corners of the Mosley at 90'.

Of course it was time to leave.

Will attempt activation again in the fall.

Message-ID: <BN6PR01MB24342B020AA01BAAE8E8DCFBCA210@BN6PR01MB2434.prod.exchangelabs.com>

All,

I'll be heading to the Mike & Key Hamfest this weekend in Puyallup, WA, with enough spare change that I hope to be able to pick up my second HT. My first is a Baofeng UV5RA, which is nice for hitting local repeaters, but I have heard is not a great choice for hitting the birds. I have a very nice Elk log periodic dual-band antenna my family got me for Father's Day last year, so I'd really like a HT to pair with it.

What's a good radio for working satellites? Is the Kenwood TH-D72a still the acme?

The TH-D72A is a full duplex radio, ideal for use on the FM birds.  They
are a bit cheaper now that the TH-D74A is out.  The D72A is also a great
APRS radio with built-in GPS.

By the way, the TH-D74A is NOT full duplex so is not particularly useful
for satellite work..

If I can?t find a TH-D72A for my budget, what?s a good go-to? It seems like most HTs aren?t full duplex.

A D7 or Yaesu FT-530 are good bets.

Hi Devin,

I am currently using a Yaesu FT-530 for FM satellites. If you can find one
on the used market for a good price, they work great! They are much cheaper
than purchasing a new or used D72.

Cheers & 73,
Tucker

It is better to ask what HT's fit SAT OPs functionality:

Everyone wants 'full duplex', I've not seen a dual-band HT that can do 'real' RX while the PTT is pushed, period! 

Nest shoot for - What dual-band HT can program SAT offsets (in the SAME single memory)?? 
My definition: in one memory can program both 2m-RX AND 70cm-PTT or vice-versa. 
Why: you only need say 4 or 5 memories per SAT for AOS/LOS OPs - one less hand needed and far less hassle.? I know Yaesu and Wuoxon can do this via PC Program. Kwood TH-F6, Icom IC-91/T8, Alinco G7 cannot they can do it only via flipping the A/B Bands (pain in the butt) - they do not allow cross band offsets in memory.? 

Now another BAD issue with Yeasu & Wuoxun is they both have a high discharge rate of battery when in the OFF state. I found if I leave my HT's on the shelf for +60days I must isolate the battery for the radio to eliminate wasteful discharging dropp[ing a B-Meter bar. I do this by using a 'paper' business-card cut it to size, sandwich between the battery and HT - isolating the battery contacts. Easy, simple, effective, cheap - what HAM Radio is all about.?

You are simply wrong. The Kenwood TH-D72, D7, D7(G) as well as the Yaesu
FT-470 and FT-530 all are excellent full-duplex HTs with no desense.

It appears you are suggesting that people operate half-duplex. That can
work somewhat, but is definitely not something I would ever recommend.

Dear friends

Do not forget the yaesu FT-51R, works perfect in full duplex mode.

Kuby,


 When was the last time you were on the satellites? I had a Yaesu FT-51R
that was full duplex. I could transmit and hear the downlink of the
satellite simultaneously. The Kenwood D72 and the D7 also do it, or are you
going to toss some engineering stuff at us to say it's not so?

Um. My D72 receiver works great while I'm transmitting.. no desense. I use
it nearly every day for FM passes.

Even the $30 Baofengs support cross-band memories for sat operations. That's how I started, but as Paul said, half-duplex on FM should not be condoned now, especially as our FM birds get more and more crowded and it becomes just an additional source of QRM. 

I've been very happy with my D72A. Packet is a nice feature to have to work ISS and NO-84.

My FT-530 most certainly does true full duplex on mode B and mode J. You
must be misinformed on the features of these HT's.

That's how I started, but as Paul said, half-duplex on FM should not be
condoned now, especially as our FM birds get more and more crowded and it
becomes just an additional source of QRM.

I've been very happy with my D72A. Packet is a nice feature to have to work
ISS and NO-84.

I find it annoying that lots of the American HT's don't support cross-band
channels. For sure, not the new Icoms, don't think the TH-F6, but all
Chinese radios I have played with will do split band channels.

I've had a lot of cheap fun.  I only have Baofeng rigs.  They work great on
all the FM birds.  To me, and maybe its just me, but it is very offputting
to be told I "must" go full duplex in order to get on the birds.  It would
be really nice if I could, but $$$ are definitely a problem for me.  I
cannot afford 2 $300+ HTs or 2 $200+ HTs or 2 $100+ HTs and 1 or 2 MFJ
diplexers at $30 each and then coax jumpers at $20 each and then an Arrow
at $160.  That's a lot of $$$ for a retiree on a fixed income.  I'm not
trying to turn this into a pity party but I'm just trying to get folks to
understand that jumping on the sats in full duplex mode ready to kick butt
and take names is not always possible.  Yes, it is a nice goal but not
always achievable by everybody.

And before someone posts erroneously that all 5 digit serial number W32As will do mode J, while SOME of them will, it actually has to do with whether or not it can be soft modded to receive 800 MHz. I know this from going through several 5 digit serial number W32As that still have/had desense.

If you come across a W32A and want to know, try this...

- Turn off radio
- Press and hold the band and squelch buttons
- Turn on the radio while holding these buttons, wait for 5 seconds before releasing them.
- Step through the bands... if you discover it now has an 800 MHz, good chance you have one that will not desense in Mode J

As always, your mileage may vary. Me, I'll be keeping an eye out for a 530 this weekend at the hamfest... I hear good things. =^)



The tricky thing with the W32A is that newer models of it desensed in Mode
J.

shop ebay, eham, QRZ and find a clean D7 for $175- full duplex plus packet for ISS/APRS. Mine has worked great for years. Only one radio and an elk, arrow, or one of the many homebrew dual band antennas. 
Superior quality and function, and definitely budget friendly

You have been using two Baofengs. You are full duplex!

That is a low cost way of doing full duplex that can be added to this
discussion - using two cheap HTs instead of one expensive HT capable
of full duplex.

Paul, N8HM

I'm with you, John. I try my best to not be annoying on the birds when
I've got my two Baofengs and my Arrow out in the backyard. If it gets to
the point where we MUST have the latest and greatest full-duplex rig,
then you'll lose me as an amateur satellite supporter.

Full duplex doesn't have to be expensive. I've made full duplex QSOs with a $5 hamfest IC-2AT and a scanner that I couldn't give away. It is however, the courteous way to operate the FM satellites, as well handy for making better, easier QSOs.

There's a lot of inexpensive ways to get on full duplex, I picked up my D72
used on eham for half of what one costs new.

And "full duplex" doesn't have to be all in one rig... 2 radios, one as a
receiver and one as a transmitter works just as well. Full duplex just
means you can hear yourself on the downlink while transmitting. I've used
an FT60r as a receiver and $20 baofeng as a transmitter. Use what you have
or can afford, listen before you tx (that goes whether you're full duplex
or not...) and have fun!

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and classroo
ms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.

guidelines and proposal form, and dates  and times of Information Sessions go

FT-51 will do full duplex on satellite. Duplexer isolation leaves much
to be desired. Moderately usable on AO-51. Useless on SO-50, though.

I vote for the FT-50 and FT-51. Personally use both.

Subject: [amsat-bb] Opinions on improving receive for portable ops
Message-ID: <34a86c.64a9493.45f43b63@aol.com>

I've just started getting on the linear transponders in the last month or  
so after a 30 year absence from sat work, necessarily with a portable setup, 
and  would be eager to hear experienced opinions on what to do next to  
improve receive.
 
I'm running Cheap Yagis on V(3 el) and U(6 el), diplexers, about 10 feet of 
 RG8X, and receiving on an FT817 or 897, usually on FO29 and the XW's,  and 
have up to 25 watts available for the uplink.
 
Q's are:
 
1) with those radios and only about 10 feet of feed line, will a preamp  
help much on 432?
 
2) If it will, is the 50$ preamp on the AMSAT site a good start? Or?  and
 
3) With relatively short yagis, will it make a noticeable difference going  
to circular polarization?  
 
WRT to 3, I've pretty much exhausted what I can find the internet, but just 
 don't have a pragmatic sense for what it will do in terms of evening out  
reception over, say, an FO 29 pass - I read that you nominally lose 3 dbs  
most all the time but may pick up a lot on the deep fades, but still not sure 
 how that translates to the real world.
 
Or is the answer that the set up is marginal enough I need to do it all of  
the above if I want reliable communications above about 5 degrees or so?
 
Thanks for the bandwidth and any input.

Dale,

As has been pointed out, there have been many HTs over the years
that allow for cross-band full-duplex operation. This was actually
a more common feature in the 1990s, and has gradually disappeared
from HTs since then. A few years ago, Andrew KE5GDB had a list of
HTs and other radios that supported cross-band full-duplex
operation on his web site. That web page is gone, but lives on
in the Internet Archive's Wayback Machine at:

http://web.archive.org/web/20090724094403/http://www.
thathamkid.com/website/ham-radio/full-duplex-radios

For HTs, you could add the TH-D72 to this list, which came out at
the end of 2010.

In addition to those HTs, there are a few others that allow for
cross-band full-duplex operation in one direction, where you are
transmitting on 70cm and listening on 2m. I wrote a bit about
a few of the Chinese-made HTs that are able to work AO-85 full-
duplex in a series of posts here on the -BB in late 2015. One
message I posted in December 2015 that had links to the other
posts I made about those radios is available at:

http://amsat.org/pipermail/amsat-bb/2015-December/056269.html

The 70cm receivers in these Chinese-made HTs suffer from desense
whenever you transmit on 2m. These radios can be programmed with
groups of memory channels to work V/U FM satellites like SO-50
half-duplex, or you could use the two VFOs to do that without the
need to program memory channels.

Using separate radios for uplink and downlink is also a good way
to have a full-duplex setup. Many have even used a pair of the
inexpensive Baofeng-type HTs to have a station capable of full-
duplex operation, or one Baofeng-type radio paired with an HT from
one of the traditional ham manufacturers.

73!

I've seen a lot of great recommendations for satellite HT's.  I really
prefer the Icom IC-910h. Since it is a little heavy for neck straps,
and the belt clip is made of 3/8" steel plate, I'd probably recommend
the BABYBJ?RN carrier approach. You can buy a 15 year old one at a
bargain price of $1000-1500 at most hamfests.

If you find manual tuning to be a drag, I recommend mounting the 910 on a
backpack frame and using a laptop to tune with a laptop harness, as seen
here:

Hmm...now how do I shoulder mount that LEO Pack?

I've used two Baofengs to work SO-50, and the V transmission from one
still desenses the U reception in the other one, even though they are
two separate radios. 

Do I put low-pass filter in the transmission line to squash that third
harmonic?

That should work, though it may not be enough depending on the front end of
the other Baofeng.

You may find you need to use a receiver with a better front end to
eliminate desense, or two filters.

You may also want to consider adjusting your power level. SO-50 can be worked with very little power and this may help with your desense.

Subject: [amsat-bb] AO-73/FUNcube Mode change
Message-ID: <080190471CD646148F0F70B866B7130A@jimPC2>

Hi folks,

  I have just changed the sat into amateur (continuous transponder) mode. Plan is to switch back to auto mode on Sunday  pm UTC as usual.

Pls see below for other FUNcube transponder info

Have FUN with the transponder.


73s Jim G3WGM and the FUNcube team.

++++++++++++++++++++++++++++++++++

FUNcube frequencies and other details

++++++++++++++++++++++++++++++++++



AO-73 FUNcube-1 

The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. 



When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) 



The nominal transponder frequencies are: 

Uplink:   435.150 - 435.130 MHz LSB (Inverting)  

Downlink:   145.950 - 145.970 MHz USB

Telemetry Tx: 145.935 MHz BPSK



(The passband may be up to 15kHz higher depending on on-board temps. Low temperatures give higher freqs!)





FUNcube-2 aka FUNcube on UKube

The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC).



The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). 



The nominal transponder frequencies are: 

Uplink:   435.080 - 435.060 MHz LSB (Inverting)  

Downlink:   145.930 - 145.950 MHz USB

Telemetry Tx: 145.915 MHz BPSK



(The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!)





EO79 FUNcube-3

Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience.



The nominal transponder frequencies are:

Uplink: 435.0723-435.0473 MHz LSB (Inverting)  

Downlink: 145.946-145.971 MHz USB 



Further detailed info on EO79 transponder frequencies is at: 

https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/







EO88 Nayif-1 FUNcube-5

EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, ie the solar panels are NOT being illuminated.  

When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power.   



The transponder frequencies are: 

Uplink:  435.045 ? 435.015 MHz LSB (inverting)

Downlink: 145.960-145.990 MHz USB

Telemetry  Tx: 145.940MHz



All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very grateful for the assistance given by Innovative Solution In Space Bv, The Netherlands.

OK - Couple different things going on here. I'll take your questions
literally first then go from there:

1) Maybe - A good preamp can help radios like FT8x7 because they don't have
the best noise figure, compared to purpose built VHF/UHF rigs like
821/910/9100. You would probably get some improvement by adding in a
quality preamp (like a ARR or a HSM) without even touching the feedline.

2) No. The AMSAT broadband pre-amp is ok for capturing telemetry, or
amplifying signals over a long coax run, but in a short run it doesn't do
anything to the already weak signals you're receiving from a bird close to
the horizon. If you wanna go the pre-amp route, a high quality purpose
built 70cm is the way to do it.

3) Yes and no.. probably no. The best thing you  can do with your yagi is
to adjust the polarity on the fly, and the best way to do that is by
holding it. Get it off the tripod, hold it in your hand, and listen to the
signal. Rotate it until the bird sounds like it's right next to you. I've
seen guys with 4 elements and a good location (more on this in a second)
work FO29 all the way to -1.0? easy copy. If you're not capable of holding
everything up, and are using a tripod, make sure it's the kind that you can
tweak polarity fast with, by rotating on the longitudinal axis. It's not as
good as holding it in your hand, but it'll do. If you're constantly
tweaking your linear polarity, no need to do the CP thing.

Now, reading between the lines on some of the questions:

You didn't ask the question, but since you said portable I have to mention
this. The absolute best tool you have at your disposal once you've freed
yourself from the shackles of a fixed QTH is LOCATION. I'm going to say it
2 more times because it's that important. LOCATION. LOCATION. By choosing
where you setup your station, you can get somewhere at a higher altitude,
clear of obstacles like trees and buildings, and away from artificial RFI.
By doing this not only can you actually get true line of site to the
horizon, where the bird will be for those long distance passes, but you'll
have the best SNR when you do finally hear it. Large parking lots work
pretty good (think Churches or Walmarts) Mountain tops, scenic overlooks,
heck even balconies or rooftops. If you're truly portable go somewhere that
you can see the horizon and is away from the noises a home. When i'm using
my portable setup in my backyard I'm lucky if i can hear most birds below
10?. When I drive 15 miles to the top of a nearby mountain, my portable
setup is good to -1.5? and I break distance records. The only thing that
changed was the location. Whenever you start talking portable, you're
talking location - and location is bar none the most important factor that
you have control over when you're talking about improving reception.

Also, use the absolute best feedline you can afford, that is convenient for
your setup. I use 8' of Times (genuine) LMR240 for my portable setup. I
know some will use the lmr240uf, or rg8x, or even an off-brand of lmr240,
but if you want the absolute best, get the good stuff. LMR400 would be
better yet, but its kinda stiff and heavy, and starts become troublesome to
use while portable, hence why LMR240 seems to be the best middle ground,
for me and the other solid /P ops.  I'm sure someone will be in to tell me
how it's only 0.1db less to use 8X or rg58 and other sorts of random
theory, but these people will be wrong. Whatever loss you get by
sacrificing feedline quality will impact your ability to hear at low
elevations.

Finally cheap yagis are nice. I used them solely for 6 months, and still
use them on occasion for guerilla operation... but a commercially built
portable antenna like an arrow is a good investment for any portable
operator. Lining up the gain of 2 separate bands on the same boom is a
difficult task for most garage builders, and you need all the gain you can
get for both tx and rx on those <5? passes. Just something to consider.

Shout if you have any other questions.

73,

Dave, KG5CCI

?Steve,

You could do that, or use a 2m/70cm diplexer as your filter
and only use the 2m side of the diplexer in line with your
SO-50 uplink radio.

I did something similar for an SO-50 demonstration at a
hamfest a couple of years ago, using two Baofeng HTs with
an Elk log periodic. You can see pictures of this setup in
a video I posted:

https://www.youtube.com/watch?v=_cLx9h-vNRA

I used a UV-82 for the uplink, and a UV-5R for the downlink,
connected through a diplexer to my Elk log periodic. I did
not experience desense with this setup, and made a good
number of contacts during this demonstration. I had to use
the diplexer with my Elk, with only one coax feedpoint, but
the diplexer also served as a good bandpass filter for the
radios.

Hi Patrick,

One topic that's generated a lot of discussion in the past has been the
difference between the Elk and Arrow portable antennas, specifically
that one has the elements in the same plane, and the other has them at
90 degrees to each other.

Was there a consensus on which gave the better results, including
operator wrist action required (a usability issue)?  I'm thinking that
some satellites have their Tx and Rx antennas at different angles,
meaning that for some the orientation where you hear the satellite best
is not the best orientation for the satellite hearing you.  I recall the
discussion, but not the results.

?Hi Greg!

I think the consensus was that Arrow users - or those with
similar crossed Yagis - needed to make a 90-degree twist
when going to transmit to AO-85, and then twist back after
your transmission. This was the case where Elk users, or
those with Yagis in the same plane, wouldn't have to make
a twist going from receive to transmit and back. For most
other satellites, this 90-degree twisting wasn't normally
required.

As with any satellite, some twisting might be needed to
counteract fading, regardless of the antenna(s) being
used by the operator. This is a separate thing from the
advice specific to AO-85, and the other upcoming Fox-1
satellites.

73!

For what it's worth, I've never found it necessary to do the rotate 90?
thing on AO-85 with an arrow and HT. I typically pay more attention to my
uplink polarity, aiming and twisting as I transmit until I hear my own
signal peak. The downlink is pretty strong on AO85, strong enough that I've
heard it with the arrow laying on the ground, not even pointing at the sat.

YMMV, but I personally wouldn't let this be a deciding factor on an arrow
vs an elk.

Clayton,

An ICOM-910H is a HT .... Really (ha ha)?  I suppose a few of you 
know that is a 100w desktop/mobile radio and hardly "portable".  But 
it is a pretty good satellite radio for multi-mode use.  A nearby 
friend uses one (actually has two) with az-el mounted yagis and full 
auto-track.

A few months ago I was looking at adding a dual-band FM mobile to my 
hamshack and kinda groaning at the the $350+ cost for a new mobile, I 
decided spending just a little more would get me a nice used 
multi-mode VHF/UHF satellite desktop/mobile radio.  Used prices on 
the Icom-910H and the FT-847 both ran $900-1200 which I could not 
justify.  Then Looked for used FT-736R and bought one for $550 
(including ctcss encoder board option) with basic 2m/70cm (no 220 or 
1.2G options).

I'm quite pleased with the "old" radio and a bit surprised in its Rx 
sensitivity without preamps, running 144 and 432 SSB with a vertical 
for contacts out to 70-miles.  I have not yet restored use of my 
satellite antennas as yet (probably be next summer as I want to move 
the short sat tower which requires new concrete base).  You can look 
on my website for some info: http://www.kl7uw.com/sat.htm

Two Baefong with appropriate filters should make an inexpensive 
portable sat setup with full duplex (not computer controlled).  A 
single Baefong plus a Funcube Rx would also work pretty good though 
you would need a notepad or equivalent.  I did some simplex FM-sat 
ops with a FT-817 in early 2000's with an Arrow but missed having 
duplex.  I also had a 1998 FT-847 but sold both in 2012.  Now have K3 
and KX3, a Baefong UV5-RA, plus the venerable FT-736R.

I've seen a lot of great recommendations for satellite HT's.  I really
prefer the Icom IC-910h. Since it is a little heavy for neck straps,
and the belt clip is made of 3/8" steel plate, I'd probably recommend
the BABYBJ?RN carrier approach. You can buy a 15 year old one at a
bargain price of $1000-1500 at most hamfests.

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.

guidelines and proposal form, and dates  and times of Information Sessions go

US ARISS Proposal Window Remains Open Through April 15, 2017

Message to US Educators Amateur Radio on the International Space
Station Contact Opportunity

Call for Proposals
Proposal Window February 15 ? April 15, 2017

The Amateur Radio on the International Space Station (ARISS) Program
is seeking formal and informal education institutions and
organizations, individually or working together, to host an Amateur
Radio contact with a crew member on board the ISS.  ARISS anticipates
that the contact would be held between January 1, 2018 and June 30,
2018. Crew scheduling and ISS orbits will determine the exact contact
dates. To maximize these radio contact opportunities, ARISS is
looking for organizations that will draw large numbers of
participants and integrate the contact into a well-developed
education plan.

The deadline to submit a proposal is April 15, 2017.  Proposal
information and documents can be found at www.arrl.org/hosting-an-
ariss-contact.

The Opportunity
Crew members aboard the International Space Station will participate
in scheduled Amateur Radio contacts. These radio contacts are
approximately 10 minutes in length and allow students to interact
with the astronauts through a question-and-answer session.

An ARISS contact is a voice-only communication opportunity via
Amateur Radio between astronauts and cosmonauts aboard the space
station and classrooms and communities. ARISS contacts afford
education audiences the opportunity to learn firsthand from
astronauts what it is like to live and work in space and to learn
about space research conducted on the ISS. Students also will have an
opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human
spaceflight and the complexity of scheduling activities aboard the
ISS, organizations must demonstrate flexibility to accommodate
changes in dates and times of the radio contact.

Amateur Radio organizations around the world, NASA, and space
agencies in Russia, Canada, Japan and Europe sponsor this educational
opportunity by providing the equipment and operational support to
enable direct communication between crew on the ISS and students
around the world via Amateur Radio. In the US, the program is managed
by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American
Radio Relay League) in partnership with NASA and CASIS (Center for
the Advancement of Science in Space).

More Information
Interested parties can find more information about the program at
www.ariss.org and www.arrl.org/ARISS.

For proposal information and more details such as expectations,
proposal guidelines and proposal form, and dates and times of
Information Sessions go to
http://www.arrl.org/hosting-an-ariss-contact.

Please direct any questions to ariss at arrl.org.

[ANS thanks ARISS for the above information]

Using a six digit grid square corrects that. I would just put in DM90mm for

I regularly try to auto receive and forward the telemetry from ALSAT-1, but
it seems to have stopped Monday, 6 March. I've received a couple of short
frames, but it could have just been noise forged packets. Didn't try
decoding them.

position  (both set to 0 degrees park position) Both the elevation and 
azimuth go to about 12 degrees - not zero. Try to correct values by  
zeroing, save and quit. restart and send back to 90 degrees again result 
in low readings.
  What am I missing?  Thanks Don.

Discovered something tonight, when satpc32 is on and controlling frequencies and the rotor I get interference on the display in SmartSDR on the 70cm side mainly ..  any ideas on what might be causing this?  I have a ERC USB inside the Yaesu G-450A control box could that be the cause?  Something being picked up across the USB cable?

US ARISS Proposal Window Remains Open Through April 15, 2017

Message to US Educators Amateur Radio on the International Space
Station Contact Opportunity

Call for Proposals
Proposal Window February 15 ? April 15, 2017

The Amateur Radio on the International Space Station (ARISS) Program
is seeking formal and informal education institutions and
organizations, individually or working together, to host an Amateur
Radio contact with a crew member on board the ISS.  ARISS anticipates
that the contact would be held between January 1, 2018 and June 30,
2018. Crew scheduling and ISS orbits will determine the exact contact
dates. To maximize these radio contact opportunities, ARISS is
looking for organizations that will draw large numbers of
participants and integrate the contact into a well-developed
education plan.

The deadline to submit a proposal is April 15, 2017.  Proposal
information and documents can be found at www.arrl.org/hosting-an-
ariss-contact.

The Opportunity
Crew members aboard the International Space Station will participate
in scheduled Amateur Radio contacts. These radio contacts are
approximately 10 minutes in length and allow students to interact
with the astronauts through a question-and-answer session.

An ARISS contact is a voice-only communication opportunity via
Amateur Radio between astronauts and cosmonauts aboard the space
station and classrooms and communities. ARISS contacts afford
education audiences the opportunity to learn firsthand from
astronauts what it is like to live and work in space and to learn
about space research conducted on the ISS. Students also will have an
opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human
spaceflight and the complexity of scheduling activities aboard the
ISS, organizations must demonstrate flexibility to accommodate
changes in dates and times of the radio contact.

Amateur Radio organizations around the world, NASA, and space
agencies in Russia, Canada, Japan and Europe sponsor this educational
opportunity by providing the equipment and operational support to
enable direct communication between crew on the ISS and students
around the world via Amateur Radio. In the US, the program is managed
by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American
Radio Relay League) in partnership with NASA and CASIS (Center for
the Advancement of Science in Space).

More Information
Interested parties can find more information about the program at
www.ariss.org and www.arrl.org/ARISS.

For proposal information and more details such as expectations,
proposal guidelines and proposal form, and dates and times of
Information Sessions go to

First Moon Bounce using Opera

On Tuesday, March 7, Luis EA5DOM and Jose EA3HMJ made a test using
the amateur radio weak-signal data mode Opera for 1296 MHz Moon
Bounce (EME)

Luis EA5DOM posted the following:

We are both using an small 180cm offset dish. Jose is 400w, so he
was transmitting and I was trying to decode. The trace was visible
but too weak for an Op05 decode. So tried Op1 switching band to
70MHz. After some trying we got one decode at -24dB

2017-03-07 23:31:17  EA3HMJ  JN11AN  EA5DOM  IM98WN
381  70.093  -  23  Op1__~24dB

Switched to Op2 and tried some times without success. I was getting
problems to keep an accurate tracking, so the signal was not optimal
and close to the decoding limit

We will keep testing, But at least one decode was worth the effort.

Here is EA5DOM screenshot:

       I have noticed while running the EO-88 dashboard that if it first 
decodes a AO-73 pass and then EO-88 comes up right after then the 
dashboard ignores the signal for a long time, if I catch it doing it and 
close and then reopen the program then it instantly locks up, does the 
program keep looking for the sat it was decoding for awhile? anyone else 
notice this behavior?

     I have also seen the FUNcube-1 dashboard do the same thing, decode 
one sat fine and then ignore the next one if it is right behind the 
first one.

Hi Kevin,

Thanks for the report!

Although we have not had any other similar reports, I have also noticed 
something similar happening and the matter was discussed last evening during 
our FUNcube team Skype chat.

If you are able to keep a note of exactly how the two dashboards are set up, 
which was started first, where the frequency limit "blinds" are, what the 
centre frequency is - or anything else that will enable our development team 
to identify the cause of the oddity then that would be very helpful!.

Many thanks

Graham

	Long Beach, CA
Message-ID: <FFDE22031B1143B2A0E06FABDB4E527A@DHJ>

An International Space Station school contact has been planned with participants at McBride High School, Long Beach, CA on 15 Mar. The event is scheduled to begin at approximately 16:28 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and K6MHS. The contact should be audible over the west coast of the U.S. and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English.

 

 

Ernest S. McBride High School (McBride) opened its doors on September 4, 2013 to an incoming class of 204 freshmen.  During the course of the past four school years, we have grown to 735 students, and we are preparing to graduate our first class of seniors.  All students are part of one of the following pathways: Criminal Justice and Investigation (CJI), McBride Engineering (ME), and Health and Medical (HM). Our campus is located in a middle-class residential neighborhood and, through our School of Choice process have students who live throughout the cities of Long Beach and Lakewood.  We are fortunate to have a student body that is both ethnically and socio-economically diverse.  Over thirty-eight percent of our student population are eligible for free or reduced lunch, and over seventy percent of the populations are from ethnic minorities.  

 

In opening a new school, we have had many unique opportunities.  The first class of McBride student chose our mascot, the Wolf, and have decided that we are collectively known as the Wolf Pack.  Our daily announcements are closed with the proclamation, "Goooo Wolfpack!"  All three of our pathways share a strong focus on math and science, learning by doing, and a preparation for both college and career.  As a sample of our project-based learning approach, our students have built solar powered boats, resolved disputes in Teen Court, earned awards for analyzing crime scenes, and conducted studies on concussions in sports.  We are fortunate to have access to updated and professional level equipment, including CNC Milling Machines, a Scanning Electron Microscope and Simulated Patient Manikins. 

 

Long Beach is the 36th most populous city in the United States and the 7th most populous in California. It is located on the Pacific Coast of the United States, within the Greater Los Angeles area of Southern California. As of 2010, its population was 462,257. Long Beach is the second largest city in the Los Angeles metropolitan area, and the third largest in Southern California behind Los Angeles and San Diego. The Port of Long Beach is the second busiest container port in the United States and is among the world's largest shipping ports. Manufacturing sectors include those in aircraft, automotive parts, electronic equipment, audiovisual equipment, petrochemicals, precision metals and home furnishings. Long Beach lies in the southeastern corner of Los Angeles County and borders Orange County. Downtown Long Beach is approximately 22 miles south of Downtown Los Angeles.

Our school district, Long Beach Unified has earned a reputation as one of America's finest school systems, winning many awards as a national and international model of excellence.

 

 

 

Participants will ask as many of the following questions as time allows:

 

1. What do you do during your free time in space?

2. Do you ever feel afraid up there in space, as you look down at the Earth, 

   and ponder how our whole world is just one grain of sand in the ocean, and     

   how our individual actions do so little to affect the course of the        

   universe?

3. What is the most used equipment when you are in space?

4. How many miles and how long does it take to break atmosphere? What did  

   that feel like?

5. Why did you give up your regular life on earth to be in space for a long   

   period of time? It seems like a big commitment. Why did you make it?

6. When I grow up I want to be an astronaut, so do you have any important 

   advice you could give to a future astronaut that helped you through your 

   journey in order to become an astronaut?

7. What could you say about climate change that others couldn't that would 

   change a climate change deniers view on the subject?

8. What happens if you run out of food?

9. What were the training requirements you went through to become an 

   astronaut?

   Can you explain what you do when you are actually in space?

   Can you explain what you do when you are NOT in space?

10. What is something you wish you would have known before becoming an  

    astronaut?

11. What do you think the benefits of having traveling exhibits like Facing 

    Mars are for young people?

12. What psychological issues have arisen in the astronauts who have spent an 

    extended time on the ISS? How are you prepared mentally to handle your 

    time in space?

13. What are you enjoying the most in the space station? 

14. Have you had a birthday on the ISS?  If so, did anyone sing happy 

    birthday to you on ham radio?

15. Have you seen ""Hidden Figures?"" Could the ISS be navigated if all the   

    calculations were done by hand?

16. We sometimes wonder if there is more than just us out there in the 

    universe, now that you're up there, has your opinion changed?

17. How different is time in space?

18. Could you imagine a musical being performed in orbit?

19. What do you think about the planned Space X trip around the moon?

20. What is the coolest trick you have done on the ISS with apparently zero  

    gravity?

21. Do you ever regret going to space?

22. How are you brave enough to risk your life to see earth from a cool view?

23. Did you know the people you currently work with on the space station 

    before you went into orbit?  How do you get along?

24. Have you ever worked on the outside of the space station? 

25. How old were you when you first seriously considered being an astronaut?

26. Is there any art you have seen on Earth that is more beautiful than the 

    Earth itself?

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.

Very nice. I was able to decode two frames of telemetry of EO-88 via 
FO-29 yesterday. I probably would have gotten more but there were some 
QSO's on the transponder exactly where EO-88 was uplinking.

         ARISS Closer to Launching New Radio System

 

March 13, 2017:   The ARISS team took a giant step closer to flying the new ARISS Interoperable Radio System to the International Space Station, having met a major milestone.  Lou McFadin, W5DID, and Kerry Banke, N6IZW, travelled to the NASA Johnson Space Center (JSC) in Houston, Texas, in mid-February for preliminary testing of Banke's breadboard version of the ARISS Multi-voltage Power Supply. The two worked alongside JSC engineers and JSC EMC lab personnel, putting the specially built power supply through its paces, checking against US and Russian space specifications for Power Quality and Electromagnetic Compatibility (EMC) preliminary tests.  

 

The result:  Outstanding news-the ARISS Team can move on to the next step, fabrication of prototype and flight units.  The JSC engineers disclosed that the ARISS breadboard power supply was the first hardware to have passed all of the space agencies' tests!  They said the very professional ARISS Team certainly knew hardware development and design.  

 

ARISS-International Chair Frank Bauer thanked Banke and McFadin for the multiple days spent putting the unit through the serious battery of NASA and Russian preliminary electrical tests.  Banke expressed pleasure with the results: "I was looking to come away with what we needed to move forward. We achieved that."  He was impressed with the support he and McFadin received from the testing group, and said key players on those teams who are also ham radio operators, commented that they find equipment brought in that is supported by ham radio operators, to earn particularly good marks.  McFadin asserted that the Multi-voltage Power Supply's fine test results are due to ARISS's team working very well together and being very experienced.  

 

The completed testing of the breadboard unit means McFadin can now purchase expensive space-certified parts so the final prototype/flight power supplies can be fabricated.  He and Banke now know that when the final, even more rigorous tests are done, the units will pass with flying colors. 

 

Watch for more news stories on the hardware and the fundraising campaign to help support the costs associated with designing, building, and testing the new ARISS radio system-the Kenwood D710GA and Multi-voltage Power Supply. Those wishing to contribute toward the final fabrication and flight tests are highly appreciated and asked to go to the AMSAT website,  www.amsat.org, to click on the "ARISS Donate" button.  Or visit the donation page on the ARISS website, http://www.ariss.org/donate.html.  Contributions are tax deductible. Those who contribute $100 or more will receive the handsome ARISS Challenge Coin.  If you or your ham club or place of employment wish to make a highly substantial contribution, contact Frank Bauer, KA3HDO, at ka3hdo at verizon.net.

 

                                                                                   

 

About ARISS

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and  National Aeronautics and Space Administration (NASA).  The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues.  With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums.  Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.  For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.

Message-ID: <CAGdEbNYG-h3rscFyLNXKgvh51YfProbT0hcWk+eMjpzvHjExSQ@mail.gmail.com>

I'm helping teach a Technician licensing class, and one of the students has
asked a question I can't answer :-) (And please correct any misinformation
in this email)

My understanding is that agencies/governments - by gentleman's agreement?
policy? - are supposed to request frequency coordination for satellites
with inputs/outputs in the amateur bands from IARU, whether the primary
payload is ham radio or not. I remember an entity a couple of years ago
which launched a satellite(s)  who did NOT go through IARU for satellite
downlink(s) on the ham bands, and there was some dust-up over this. (Again,
please help me understand this better if I'm mistaken.)

My student's question is this; who is responsible for frequency assignments
for non-ham satellites, specifically, missions like Cassini and
Voyager/Pioneer?  Is it ITU?

I'm sure the military - and government (and commercial interests)  - in
other countries have their own satellite frequencies, but for scientific
payloads, who is responsible for frequency allocation/coordination in near
Earth orbits and intra-galactic ones? Is is ITU?

(This started a whole new thought bubble in my head about what would be the
best/appropriate frequencies for missions like Cassini (antenna size and
Doppler considerations, but that is for a different email, as I want to
wrestle with those questions in my head first  :-)  )

Thanks

Philip,

For the US: If the satellite owner is a government organization the NITA 
controls the frequencies and assignments. For large agencies like NASA 
they have a team of people who do nothing but this and blocks of 
frequencies that NTIA lets them manage themselves (for the most part).

All others are managed by the FCC.  For example a commercial TV 
broadcast satellite must obtain an FCC license. There are many 
categories of FCC licenses and many blocks of frequencies that are more 
or less dedicated to certain uses.

Let me provide the following on how Amateur satellites and Experimental 
satellites that may be licensed in spectrum allocated to the Amateur 
Radio Service works. This again applies to the US (other countries have 
other methods and procedures).

If someone like AMSAT builds a satellite for the use of Amateur 
licensees, and it wants to use frequencies allocated to the ARS, it 
first obtains coordination from the IARU then follows the notification 
procedures in part 97.  The FCC part is pretty straight forward.  The 
transmitter(s) in the satellite are operated under someones existing ARS 
license much like a mountain top repeater is operated under the license 
of a person (or perhaps a club).  The frequencies to be used are 
coordinated by the Satellite Advisor to the IARU and his international 
committee of advisors. What that means is the builder provides the info 
on what freqs they would like to use, the nature of the satellite, their 
commanding methods and other technical details to the IARU on their 
form, and the IARU coordination team gets together and 'coordinates' 
those frequencies. Coordination means they look at all other sats using 
those bands and work at keeping them on separate frequencies so they 
don't interfere with each other (or cooperatively share them).  In the 
notification process to the FCC you must include the info from the IARU 
that you have coordinated your frequencies.  The IARU team does this for 
all amateur sates from all countries (to the extent those countries 
cooperate and participate, not all do.)

If someone wants to use frequencies in ARS allocated spectrum for 
something other than an Amateur satellite, like scientific or 
Experimental cubesats from universities or commercial companies, they 
can ask the FCC Experimental branch for an experimental license.  But 
the FCC Experimental brance won't give them a license unless the IARU 
has coordinated their proposed frequencies (again, keeping them apart so 
they don't interfere with Amateur or other experimental usage).  
Experimental licensees must accept any and all interference from 
licensed operations and must not interfere with any licensed 
operations.  There is no assurance that the IARU will agree with the 
frequencies chosen or that they will provide coordination at all.  Those 
experimental licensees and operations are something between guests and 
interlopers in the Amateur allocated spectrum.  The IARU endeavors to 
keep the experimentals separated from the Amateur by sort of using one 
end of a band for Amateur and the other for Experimentals.

The IARU has done a great job of this very complicate and difficult task 
over the years as the number of both Amateur and Experimental satellites 
proposed and on orbit has increased hugely.  It's very hard.  And most 
of those building experimantals don't know how this works or what they 
must do.  Sometimes they buy hardware (radios and antennas) for their 
satellite without understanding how this works to find they can't get 
licensed where they want to be.  That's costly.

In the past month I've sat as a reviewer for three university small 
satellite projects none of which understood this and one of which has 
radios they are not going to be able to use because they can't get an 
experimental license in that band.

We could certainly use local AMSAT folks with satellite experience as 
mentors for the COMM part of most of the university driven small and 
cubsats.  It's a great opportunity to educate some young people and keep 
them from making technical and regulatory errors.  And some of these 
projects can turn into Amateur satellites after their experimental or 
science mission is over.  I'm working with one right now that has the 
potential to be a great Amateur on orbit resource - the owner is done 
with it and looking to turn it over to AMSAT if we can get it fully 
working in various modes again.

The ITU sets aside spectrum for ?space science services? which includes
both radio astronomy and scientific spacecraft operation.    The US is a
member of the ITU, and in this country licensing and frequency usage is
regulated by both the  NTIA and FCC.  In general, NASA must work with
both organizations.

I guess this happens as a result of the recent successes in cubesats,
other organisations see their opportunity but start of at a lower knowledge
level. But given the amounts of money still involved, one would hope
research into this factor would be done before investing in hardware.

And be aware interest in cubesats may come from outside areas of science
logically connected with space technology.

I can fully imagine the geo sciences department at my employer (large Dutch
university) being interested in space-based sensing.

Is there a good article somewhere describing the process you posted about?
A "how-to" document, with the international view on this process.
I notice the AMSAT north america site mentions the IARU when describing
frequency allocations to satellites, which is a very good start.

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.  

For proposal information and more  details such as expectations, proposal 
guidelines and proposal form, and dates  and times of Information Sessions go

Hi all,

Its hard to explain these complicated international affairs.
All countries that are participating in the ITU are bound by treaties
to follow the rules set by the ITU.

ITU defines "services" that describe what the radio communications is
for. Examples are:
Fixed-satellite service; Fixed station, Inter-satellite service, Earth
exploration-satellite service, Meteorological-satellite service
and for "us" the Amateur Service and Amateur Satellite Service.

ITU defines these services and does not allow a mix of services, so
you need to find spectrum that is allocated to your service.
The administration or administrations of your country that is handling
ITU related matters is the entity that can file for frequencies,
notify and coordinate with ITU et cetera. Ultimately, the
administration is responsible for your satellite. Its up to that
country to decide how to implement the regulatory process on a
national level. Jim already addressed this for the US. Here in the
Netherlands we have "Agentschap Telecom", in the UK they have "ofcom"
and in Germany the "Bundesnetzagentur".

To reduce the workload on the administrations, they often require the
satellite teams to fill in the application themselves, and will do a
sanity check on it before filing. Again, the country is liable, so its
in the administrations interest to make sure its correct.

The ITU does not say anything about coordination in the bands
allocated to the Amateur Satellite Service, as they are Not Subject to
Coordination. Coordination is a formal process where administrations
operating services exchange information about possible new systems and
do interference analysis. the Amateur Satellite Services in 2m and
70cm are Not Subject to Coordination, so you would only have to do two
things:
- Publish, through ITU, the Advance Publication Information (API).
Administrations can review your application and object if they think
you will cause interference
- Publish, through ITU, a Notification, where you describe the final
system and confirm you are going to use that system

In good amateur tradition, the national administrations that recognise
IARU have agreed to ask for guidance from IARU and respect their band
plans. the IARU in turn has appointed a panel that coordinates
satellite frequencies. Some administrations will refuse to allow
notification to the ITU without a positive IARU advice.
The US is the odd one out with the experimentals coordinated on top of
the Amateur Satellite Service, and as far as I know are the only
administration doing so.

Now back to these services: in order to allocate something in the
Amateur Satellite Service, it needs to comply with the rules for this
service as stated in the radio regulations.
"Amateur Service: A radiocommunication service for the purpose of
self-training, intercommunication and technical investigations carried
out by amateurs, that is, duly authorised persons interested in radio
technique solely with a personal aim and without pecuniary interest."
[RR 1.56]"
and
"Amateur-Satellite Service: A radiocommunication service using space
stations on Earth satellites for the same purposes as those of the
amateur service." [RR 1.57]"

So in short:
- Make sure your project belongs in the Amateur Satellite Service (you
would be surprised to learn what people think is "useful" for radio
amateurs)
- Apply for frequencies at the IARU panel, and with the IARU
frequencies go to your national regulator
- Apply at your national regulator
- Your national regulator then probably ask you to provide the API
files, and submits those to the ITU
- other administrations may send their comments on your proposed
network. Your administration needs to reply to those, probably asking
you for help again
- Your administration published the NOTIFICATION six months or later
from date of receipt of the API

In case of scientific satellites, there is no IARU, and the process
gets complicated fast. There are lost of bands that are subject to
coordination. You need to show other parties in the same bands that
you will not cause harmful interference to their systems, The big
space agencies have some frequencies set aside that they re-use, so
the workload is reduced. But in general, it can become a lengthy
process.

I hope that explains it a bit more. And other experts feel free to
correct and amend, its complicated and I am paraphrasing a lot. there
is lots of sensitivities and subtleties in the wording of the radio
regulations that I can not simply convey here.

  Thank you dear Trevor and Wouter for your detailed and comprehensive
information regarding the usage of Amateur radio frequencies and subsequent
procedure, importance of coordination/ filing of frequencies for
cubesat/nanosat projects. I too feel that this info should reach all those
people well in advance, who intend to use amateur radio frequencies for
their cubesat/nanosat projects.

Much of the information you?re looking for comes in an IARU paper called Amateur Satellites <http://www.iaru.org/amateur-radio-satellite-frequency-coordination.html>.  Also, suggest reading Controlling Satellites [PDF] <http://www.iaru.org/uploads/1/3/0/7/13073366/controllingsatellites_v27.pdf> and the IARU Frequency Coordination Request [doc] <http://www.iaru.org/uploads/1/3/0/7/13073366/iaru_amateur_satellite_coordination_request__v37.doc>.

I hope this helps.

Hi!

I will have an AMSAT booth at the Scottsdale Amateur Radio
Club's SpringFest hamfest on Saturday morning, 18 March
2017. The hamfest will be held at the Mountain Valley campus
of Scottsdale Bible Church on Perimeter Drive, west of the
AZ-101 freeway exit 36, and north of Princess Drive, in
Scottsdale, Arizona. This is a half-day hamfest, since
everyone has to clear out of the church's parking lot by
1pm (2000 UTC). The hamfest officially starts at 8am (1500
UTC), but I expect people to be roaming around the parking
lot before sunrise. More information about the hamfest is
available at:

http://www.scottsdalearc.org/spring-fest

I plan on doing a series of on-air demonstrations of satellite
operating during the morning as WD9EWK. There are a bunch of
passes for FM, SSB, and packet operations that I could show up
on. If you hear or see WD9EWK on a pass Saturday morning,
please call and be a part of the demonstrations. Any QSOs
attempted via NO-84 and the ISS will also use WD9EWK as my
call sign, without the -9 SSID I have used for demonstrations
in the past. All QSOs made during the hamfest will be uploaded
to Logbook of the World after the hamfest. If you'd like a QSL
card for a QSO, please e-mail me directly with the QSO details.

During the hamfest, I will post updates from the hamfest, along
with photos, on my @WD9EWK Twitter account. If you want to see
these updates and you do not use Twitter, do not worry. You can
use a web browser to follow along, at:

http://twitter.com/WD9EWK

Thanks in advance, and 73!

Hi folks,

FUNcube/AO73 is now in full time amateur mode with the transponder ON. The 
plan is for it to switch back to auto mode on Sunday  pm UTC as usual but, 
for operational reasons, this may be delayed until Monday pm UTC.

Please  see below for other FUNcube transponder info

Have FUN with the transponder.

73s Graham G3VZV and the FUNcube team.

++++++++++++++++++++++++++++++++++
FUNcube frequencies and other details
++++++++++++++++++++++++++++++++++

AO-73 FUNcube-1

The transponder is normally operational only when the satellite is in 
eclipse, ie the solar panels are NOT being illuminated. During weekends 
(from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.

When the transponder is switched off, the telemetry beacon is on full power, 
when the transponder is on the beacon it is on low power. During holidays, 
eg Christmas, New Year, Easter, etc, the transponder maybe activated for 
extended periods. Watch AMSAT-BB for announcements which are usually made on 
Friday evenings (UTC)

The nominal transponder frequencies are:

Uplink:   435.150 - 435.130 MHz LSB (Inverting)
Downlink:   145.950 - 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK

(The passband may be up to 15kHz higher depending on on-board temps. Lower 
temperatures give higher freqs!)

FUNcube-2 (aka FUNcube on UKube)

The FUNcube-2 sub-system continues to operate autonomously and, almost 
continuously, in amateur mode. The transponder is operational and the 
telemetry downlink is functioning with about 70mW output. The FUNcube-1 
Dashboard does not correctly display the telemetry but it does correctly 
decode the data and uploads it to the FUNcube Data Warehouse from where it 
can be examined. Most of the real time data channels are operational and 
these include battery voltages, temperatures and ADCS data coming via the 
main On Board Computer (OBC).

The transponder is interrupted for a few seconds every 2 minutes when the 
other transmitter sends its CW beacon and, occasionally, for a few seconds 
when the main OBC reboots (approx seven times each orbit).

The nominal transponder frequencies are:
Uplink:   435.080 - 435.060 MHz LSB (Inverting)
Downlink:   145.930 - 145.950 MHz USB
Telemetry Tx: 145.915 MHz BPSK

(The passband may be up to 10kHz higher depending on on-board temps. Low 
temperatures give higher freqs!)


EO79 FUNcube-3
Due to power budget constraints the transponder cannot be operational 24/7 
and an orbit specific schedule has been developed. The transponder will 
commence operation 27 minutes after the spacecraft enters sunlight and will 
stay on for a period of 25 minutes. This schedule may be modified in future 
months as a result of experience.

The nominal transponder frequencies are:
Uplink: 435.0723-435.0473 MHz LSB (Inverting)
Downlink: 145.946-145.971 MHz USB

Further detailed info on EO79 transponder frequencies is at:
https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/


EO88/Nayif-1/FUNcube-5

EO88 is presently operating in autonomous mode. The transponder is 
operational when the satellite is in eclipse, ie the solar panels are NOT 
being illuminated.
When the transponder is switched off, the telemetry beacon is on full power, 
when the transponder is on the beacon it is on low power.
The transponder frequencies are:

Uplink:  435.045 ? 435.015 MHz LSB (inverting)
Downlink: 145.960-145.990 MHz USB
Telemetry  Tx: 145.940MHz

All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very 
grateful for the assistance given by Innovative Solution In Space Bv, The 
Netherlands.

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.

George MI6GTY is planning to operate from IO54 on
26March on possibly two FO-29 passes, 1158 and
1351 utc.  The first pass will cover extreme
northeast USA but the second pass will cover
more than half of the US.

As before, he would like to be sure that there will
be enough interest to warrant the trip.  So if you
can be there, please drop him an email and let him know.

The second pass provides a very short window for southern
States like Texas and Florida etc.  So if you live in
the north, please wait a bit before calling and let the
south get a contact first.

The second pass is only  2.2 degrees max for George.  He
was very successful with low elevation at IO65 and let's hope
he can be just as successful in IO54.

AMSAT Ground Terminal Weekly Report for March 7, 2017


We kick off this week?s report with two demonstrations of DVB-S2 
transmission from the LimeSDR. The first from Charles Brain G4GUO, and 
the second from Paul KB5MU and Michelle W5NYV. Charles has live video 
and Paul and Michelle are transmitting a pre-recorded work of art called 
Adventure Time.

Mike Seguin N1JEZ has some LimeSDR spectral analysis to report.
https://www.youtube.com/watch?v=_ZNshry3sZU
First, 850 MHz Phase Noise 10 kHz offset 1 kHz resolution bandwidth
-58.36 ? 10LOGBW = -88.36 dBc/Hz
If I read the LMS7002M Spec sheet right, it should be down around -96 
dBc/Hz? PDF is in the Phase 4 Ground Github link is in the show notes.
https://github.com/?/d?/tree/master/Engineering/SDRs/LimeSDR
Second, 2850 MHz Phase Noise 10 kHz offset 1 kHz resolution bandwidth
-49 ? 10LOGBW = -79 dBc/Hz spec around -87 dBc/Hz?
Third image is at 2850 MHz +/-200 kHz
Check out those curious 200 kHz spurs
Fourth image is 2850 MHz 100 MHz Span
A broader view ? we need to go digging deeper.
Final image is 2850 MHz 388 kHz spur
small spur on the low side?
Output power varies. He?s seen upwards of +15 dBm. He is powering the 
LimeSDR board off an external supply.
He is using LimeSuite to set up the transmit output on TX1-1. There are 
so many settings it?s possible/probable we?re missing something.

He has also have done rudimentary noise figure measurements. Paul, W1GHZ 
loaned him a homebrew noise head he had built from his QEX article in 
1996? on Noise Figure. He used it to measure the NF, but had to rely on 
a chart for ENR. So assumptions!!! He found he definitely had to use a 
preamp in front of the Lime. He used an AD6IW wideband pre for testing.

?I need to do more real world tests on the bands?.? -Mike Seguin


In the next segment of this report Paul described how to use the 
examples folder in GNU Radio to get to the DVB flowgraphs we?ve been 
using for experiments.

Charles G4GUO shares his plan for next steps for DVB-S2 receive. He is 
looking at how to do the front end that finds the start of a frame and 
compensates for frequency error. He is pondering how to do this and has 
some ideas. He also has the low density parity check (LDPC) decoder to 
do but has not yet planned it out. He has the BCH decoder done and the 
bit that decodes the preamble code FEC.

Charles explains that the whole of DVB-S2 has been designed for the 
parallel processing powers of ASICs/FPGAs/GPUs. He has decided to attack 
the problem using GPUs.

He asserts that GPUs don?t have such a steep learning curve as some of 
the other technologies. He believes that the symbol tracking and root 
raised cosine filtering is best done in the FPGA on the LimeSDR. His 
thoughts are to re-write some of the Lime code so he can alter the ADC 
sample rate in fractions of a symbol. Then use the host to calculate the 
timing error and send the correction to the Lime FPGA code. The Lime can 
also do fine frequency error correction using a complex mixer. The error 
can be calculated in the host from the phase change in the preamble 
sequence.

The central question is how to fit it into the memory model of the GPU 
to keep all the threads fully occupied. This means properly balancing 
the combination of LDPC decoding, parallel thinking and NVIDIA GPU 
programming. One of the many questions he has is how to cope with the 
final XOR of the parity bit for each block as that makes every bit in 
the whole thing dependent on every other bit. He believes that there 
must be a short cut so you can break the problem at the receiver down 
into a load of independent blocks (divide and conquer).

It is all very DVBS2 specific but when a sub block of the code meets a 
condition where all its parity check equation are correct it can be 
marked as finished and the decoder can then move on to the next sub 
block. It requires a lot of thinking about and Charles welcomes your 
feedback.

So! Lots of programming! We are here to help with this effort! It?s 
going to be a big one.

Please join AMSAT, TAPR, ARRL, and any other local or regional club that 
is helping advance the state of the art in amateur radio. Projects like 
ours cannot exist without your membership.

CAS-4A and CAS-4B Linear Transponder Frequencies Announced


CAMSAT has worked closely with a Beijing Government aerospace contractor 
to build two satellites with amateur radio linear transponder payloads. 
IARU record a launch had been planned for March 31, 2017 from Taiyuan 
into a 524 km orbit with an inclination of 42 degrees.

Both will carry a 435/145 (U/V) 20 dBm (100 milliwatt) SSB/CW linear 
transponder, a 2m CW 17 dBm (50 mW) telemetry beacon and an AX.25 4.8 
kbps GMSK 20 dBm (100 mW) telemetry downlink.

The two micro-satellites will also carry optical remote sensing 
missions. Planned to be 494x499x630 mm dimension regular square shape 
and approximately 50 kg mass with three-axis stabilization system.

These frequencies have been coordinated by the IARU Satellite Frequency 
Coordination Panel:

CAS-4A
? Linear transponder downlink 145.870 MHz, emission designator 
20K0V8WWF, output power 20 dBm
? Linear transponder uplink 435.220 MHz
? CW telemetry beacon 145.855 MHz, emission designator 100HA1AAN, output 
power 17 dBm
? GMSK telemetry 145.835 MHz, emission designator 16K0F1DCN, output 
power 20 dBm

CAS-4B
? Linear transponder downlink 145.925 MHz, emission designator 
20K0V8WWF, output power 20 dBm

ARISS Closer to Launching New Radio System


March 13, 2017:   The ARISS team took a giant step closer to flying the 
new ARISS Interoperable Radio System to the International Space Station, 
having met a major milestone.  Lou McFadin, W5DID, and Kerry Banke, 
N6IZW, travelled to the NASA Johnson Space Center (JSC) in Houston, 
Texas, in mid-February for preliminary testing of Banke's breadboard 
version of the ARISS Multi-voltage Power Supply. The two worked 
alongside JSC engineers and JSC EMC lab personnel, putting the specially 
built power supply through its paces, checking against US and Russian 
space specifications for Power Quality and Electromagnetic Compatibility 
(EMC) preliminary tests.

The result:  Outstanding news-the ARISS Team can move on to the next 
step, fabrication of prototype and flight units.  The JSC engineers 
disclosed that the ARISS breadboard power supply was the first hardware 
to have passed all of the space agencies' tests! They said the very 
professional ARISS Team certainly knew hardware development and design.

ARISS-International Chair Frank Bauer thanked Banke and McFadin for the 
multiple days spent putting the unit through the serious battery of NASA 
and Russian preliminary electrical tests.  Banke expressed pleasure with 
the results: "I was looking to come away with what we needed to move 
forward. We achieved that."  He was impressed with the support he and 
McFadin received from the testing group, and said key players on those 
teams who are also ham radio operators, commented that they find 
equipment brought in that is supported by ham radio operators, to earn 
particularly good marks.  McFadin asserted that the Multi-voltage Power 
Supply's fine test results are due to ARISS's team working very well 
together and being very experienced.

The completed testing of the breadboard unit means McFadin can now 
purchase expensive space-certified parts so the final prototype/flight 
power supplies can be fabricated.  He and Banke now know that when the 
final, even more rigorous tests are done, the units will pass with 
flying colors.

Watch for more news stories on the hardware and the fundraising campaign 
to help support the costs associated with designing, building, and 
testing the new ARISS radio system-the Kenwood D710GA and Multi-voltage 
Power Supply. Those wishing to contribute toward the final fabrication 
and flight tests are highly appreciated and asked to go to the AMSAT 
website,  www.amsat.org, to click on the "ARISS Donate" button.  Or 
visit the donation page on the ARISS website, 
http://www.ariss.org/donate.html. Contributions are tax deductible. 
Those who contribute $100 or more will receive the handsome ARISS 
Challenge Coin.  If you or your ham club or place of employment wish to

exploration of science, technology, engineering, and mathematics (STEM) 
topics by organizing scheduled contacts via amateur radio between crew 
members aboard the ISS and students in classrooms or informal education 
venues.  With the help of experienced amateur radio volunteers, ISS 
crews speak directly with large audiences in a variety of public 
forums.  Before and during these radio contacts, students, teachers, 
parents, and communities learn about space, space technologies, and 
amateur radio.  For more

ARISS News


Successful Contacts

*  A direct contact with students at McBride High School, Long Beach, 
CA, USA was successful Wed 2017-03-15 16:28:44 UTC 25 deg. Astronaut 
Thomas Pesquet, KG5FYG answered all 19 questions prepared by students.


Upcoming Contacts

*  A telebridge contact via W6SRJ with students at ?School of Trois  
Paletuviers?, Saint-Georges de l'Oyapock, French Guyana, is presently 
scheduled Thu 2017-03-23 12:42:26 UTC 61 deg. with Astronaut Thomas 
Pesquet KG5FYG.

Trois Pal?tuviers is a small native people village of French Guyane, set 
between the Amazonian forest and the majestic Oyapock River, a natural 
border with Brazil. It is accessed only by dugout and the journey takes 
place in one hour. On site, no electricity during the day, internet and 
telephone recently, but a quality of life preserved, which in no way 
excludes projects and achievements in order to help envisage the future 
in a dynamic and optimistic way. The village comprises a population of 
180 inhabitants, exclusively Native Americans and many of whom have 
strong ties with Brazil.

The school hosts about fifty students divided into 2 classes: a 
kindergarten from the PS to the GS, an elementary from the CP to the 
CM2. In addition to the usual teachings, the school offers activities 
that enable you to travel and make contact with the outside of the 
village. So :

The "chess game for academic success" has been helping since 2006 to 
reason and confidence in its abilities,
The theater club has already performed several times in French Guiana.
A highly eclectic choir gives everyone the opportunity to express 
themselves.

In addition, there are urban dance classes, numerous programs and 
projects related to the environment, space, health and so on.
Another peculiarity is that a school for parents has been in place since 
2011.

For the liaison with the ISS, the pupils will travel 1 hour of canoe 
motor and 3 hours of road.

*  A direct contact via AA4UT with students at the Student Space 
Technology Association, Knoxville, TN, USA  will be rescheduled.

The University of Tennessee Knoxville is an amazing school located in 
the hills of Tennessee. It is the largest campus in the state, hosting 
more than 30,000 students. This school is known for its engineering and 
science heritage, having close ties with research facilities such as Oak 
Ridge National Lab and companies like Alcoa. Also, included in our 
alumni are 9 astronauts including the recent ISS inhabitant Scott Kelly. 
Our school is filled with thousands of eager students seeking to pursue 
careers in the space industry. With our vision of becoming a top-tier 
research school, our students are set to become the next leaders in STEM 
industries.

Message to US Educators
Amateur Radio on the International Space Station
Contact  Opportunity

Call for Proposals
Proposal Window February 15 ?  April 15, 2017

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with 
a crew member on board the ISS.  ARISS anticipates that the  contact 
would be held between January 1, 2018 and June 30, 2018. Crew 
scheduling  and ISS orbits will determine the exact contact dates. To 
maximize these radio contact opportunities, ARISS is ;
looking for organizations that will draw large numbers of
participants and integrate the contact into a well-developed education
plan.

The deadline to submit a proposal is April 15,  2017.  Proposal 
information and documents can be found at
www.arrl.org/hosting-an-ariss-contact.

The Opportunity
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are 
approximately 10 minutes in  length and allow students to interact with 
the astronauts through a question-and-answer session.

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford education audiences 
the opportunity to learn firsthand from astronauts what it  is like to 
live and work in space and to learn about space research conducted on  
the ISS. Students also will have an opportunity to learn about 
satellite  communication, wireless technology, and radio science. 
Because of the nature of human spaceflight and the complexity of 
scheduling activities aboard the ISS,  organizations must demonstrate 
flexibility to accommodate changes in dates and  times of the radio 
contact.

Amateur Radio organizations around the  world, NASA, and space agencies 
in Russia, Canada, Japan and Europe sponsor this educational opportunity 
by providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via 
Amateur Radio.
In the US, the program is managed by AMSAT (Radio  Amateur Satellite
Corporation) and ARRL (American Radio Relay League) in partnership with 
NASA and CASIS (Center for the Advancement of Science in  Space).

More Information
Interested parties can find  more information about the program at

AMSAT Ground Terminal Weekly Report for March 7, 2017


We kick off this week?s report with two demonstrations of DVB-S2 
transmission from the LimeSDR. The first from Charles Brain G4GUO, and 
the second from Paul KB5MU and Michelle W5NYV. Charles has live video 
and Paul and Michelle are transmitting a pre-recorded work of art called 
Adventure Time.

Mike Seguin N1JEZ has some LimeSDR spectral analysis to report.
https://www.youtube.com/watch?v=_ZNshry3sZU
First, 850 MHz Phase Noise 10 kHz offset 1 kHz resolution bandwidth
-58.36 ? 10LOGBW = -88.36 dBc/Hz
If I read the LMS7002M Spec sheet right, it should be down around -96 
dBc/Hz? PDF is in the Phase 4 Ground Github link is in the show notes.
https://github.com/?/d?/tree/master/Engineering/SDRs/LimeSDR
Second, 2850 MHz Phase Noise 10 kHz offset 1 kHz resolution bandwidth
-49 ? 10LOGBW = -79 dBc/Hz spec around -87 dBc/Hz?
Third image is at 2850 MHz ?200 kHz
Check out those curious 200 kHz spurs
Fourth image is 2850 MHz 100 MHz Span
A broader view ? we need to go digging deeper.
Final image is 2850 MHz 388 kHz spur
small spur on the low side?
Output power varies. He?s seen upwards of +15 dBm. He is powering the 
LimeSDR board off an external supply.
He is using LimeSuite to set up the transmit output on TX1-1. There are 
so many settings it?s possible/probable we?re missing something.

He has also have done rudimentary noise figure measurements. Paul, W1GHZ 
loaned him a homebrew noise head he had built from his QEX article in 
1996? on Noise Figure. He used it to measure the NF, but had to rely on 
a chart for ENR. So assumptions!!! He found he definitely had to use a 
preamp in front of the Lime. He used an AD6IW wideband pre for testing.

?I need to do more real world tests on the bands?.? -Mike Seguin


In the next segment of this report Paul described how to use the 
examples folder in GNU Radio to get to the DVB flowgraphs we?ve been 
using for experiments.

Charles G4GUO shares his plan for next steps for DVB-S2 receive. He is 
looking at how to do the front end that finds the start of a frame and 
compensates for frequency error. He is pondering how to do this and has 
some ideas. He also has the low density parity check (LDPC) decoder to 
do but has not yet planned it out. He has the BCH decoder done and the 
bit that decodes the preamble code FEC.

Charles explains that the whole of DVB-S2 has been designed for the 
parallel processing powers of ASICs/FPGAs/GPUs. He has decided to attack 
the problem using GPUs.

He asserts that GPUs don?t have such a steep learning curve as some of 
the other technologies. He believes that the symbol tracking and root 
raised cosine filtering is best done in the FPGA on the LimeSDR. His 
thoughts are to re-write some of the Lime code so he can alter the ADC 
sample rate in fractions of a symbol. Then use the host to calculate the 
timing error and send the correction to the Lime FPGA code. The Lime can 
also do fine frequency error correction using a complex mixer. The error 
can be calculated in the host from the phase change in the preamble 
sequence.

The central question is how to fit it into the memory model of the GPU 
to keep all the threads fully occupied. This means properly balancing 
the combination of LDPC decoding, parallel thinking and NVIDIA GPU 
programming. One of the many questions he has is how to cope with the 
final XOR of the parity bit for each block as that makes every bit in 
the whole thing dependent on every other bit. He believes that there 
must be a short cut so you can break the problem at the receiver down 
into a load of independent blocks (divide and conquer).

It is all very DVBS2 specific but when a sub block of the code meets a 
condition where all its parity check equation are correct it can be 
marked as finished and the decoder can then move on to the next sub 
block. It requires a lot of thinking about and Charles welcomes your 
feedback.

So! Lots of programming! We are here to help with this effort! It?s 
going to be a big one.

Please join AMSAT, TAPR, ARRL, and any other local or regional club that 
is helping advance the state of the art in amateur radio. Projects like 
ours cannot exist without your membership.

CAS-4A and CAS-4B Linear Transponder Frequencies Announced


CAMSAT has worked closely with a Beijing Government aerospace contractor 
to build two satellites with amateur radio linear transponder payloads. 
IARU record a launch had been planned for March 31, 2017 from Taiyuan 
into a 524 km orbit with an inclination of 42 degrees.

Both will carry a 435/145 (U/V) 20 dBm (100 milliwatt) SSB/CW linear 
transponder, a 2m CW 17 dBm (50 mW) telemetry beacon and an AX.25 4.8 
kbps GMSK 20 dBm (100 mW) telemetry downlink.

The two micro-satellites will also carry optical remote sensing 
missions. Planned to be 494x499x630 mm dimension regular square shape 
and approximately 50 kg mass with three-axis stabilization system.

These frequencies have been coordinated by the IARU Satellite Frequency 
Coordination Panel:

CAS-4A
? Linear transponder downlink 145.870 MHz, emission designator 
20K0V8WWF, output power 20 dBm

ARISS Closer to Launching New Radio System


March 13, 2017:   The ARISS team took a giant step closer to flying the 
new ARISS Interoperable Radio System to the International Space Station, 
having met a major milestone.  Lou McFadin, W5DID, and Kerry Banke, 
N6IZW, travelled to the NASA Johnson Space Center (JSC) in Houston, 
Texas, in mid-February for preliminary testing of Banke's breadboard 
version of the ARISS Multi-voltage Power Supply. The two worked 
alongside JSC engineers and JSC EMC lab personnel, putting the specially 
built power supply through its paces, checking against US and Russian 
space specifications for Power Quality and Electromagnetic Compatibility 
(EMC) preliminary tests.

The result:  Outstanding news-the ARISS Team can move on to the next 
step, fabrication of prototype and flight units.  The JSC engineers 
disclosed that the ARISS breadboard power supply was the first hardware 
to have passed all of the space agencies' tests! They said the very 
professional ARISS Team certainly knew hardware development and design.

ARISS-International Chair Frank Bauer thanked Banke and McFadin for the 
multiple days spent putting the unit through the serious battery of NASA 
and Russian preliminary electrical tests.  Banke expressed pleasure with 
the results: "I was looking to come away with what we needed to move 
forward. We achieved that."  He was impressed with the support he and 
McFadin received from the testing group, and said key players on those 
teams who are also ham radio operators, commented that they find 
equipment brought in that is supported by ham radio operators, to earn 
particularly good marks.  McFadin asserted that the Multi-voltage Power 
Supply's fine test results are due to ARISS's team working very well 
together and being very experienced.

The completed testing of the breadboard unit means McFadin can now 
purchase expensive space-certified parts so the final prototype/flight 
power supplies can be fabricated.  He and Banke now know that when the 
final, even more rigorous tests are done, the units will pass with 
flying colors.

Watch for more news stories on the hardware and the fundraising campaign 
to help support the costs associated with designing, building, and 
testing the new ARISS radio system-the Kenwood D710GA and Multi-voltage 
Power Supply. Those wishing to contribute toward the final fabrication 
and flight tests are highly appreciated and asked to go to the AMSAT 
website,  www.amsat.org, to click on the "ARISS Donate" button.  Or 
visit the donation page on the ARISS website, 
http://www.ariss.org/donate.html. Contributions are tax deductible. 
Those who contribute $100 or more will receive the handsome ARISS 
Challenge Coin.  If you or your ham club or place of employment wish to 
make a highly substantial contribution, contact Frank Bauer, KA3HDO, at

ARISS News


Successful Contacts

*  A direct contact with students at McBride High School, Long Beach, 
CA, USA was successful Wed 2017-03-15 16:28:44 UTC 25 deg. Astronaut 
Thomas Pesquet, KG5FYG answered all 19 questions prepared by students.


Upcoming Contacts

*  A telebridge contact via W6SRJ with students at ?School of Trois  
Paletuviers?, Saint-Georges de l'Oyapock, French Guyana, is presently 
scheduled Thu 2017-03-23 12:42:26 UTC 61 deg. with Astronaut Thomas 
Pesquet KG5FYG.

Trois Pal?tuviers is a small native people village of French Guyane, set 
between the Amazonian forest and the majestic Oyapock River, a natural 
border with Brazil. It is accessed only by dugout and the journey takes 
place in one hour. On site, no electricity during the day, internet and 
telephone recently, but a quality of life preserved, which in no way 
excludes projects and achievements in order to help envisage the future 
in a dynamic and optimistic way. The village comprises a population of 
180 inhabitants, exclusively Native Americans and many of whom have 
strong ties with Brazil.

The school hosts about fifty students divided into 2 classes: a 
kindergarten from the PS to the GS, an elementary from the CP to the 
CM2. In addition to the usual teachings, the school offers activities 
that enable you to travel and make contact with the outside of the 
village. So :

The "chess game for academic success" has been helping since 2006 to 
reason and confidence in its abilities,
The theater club has already performed several times in French Guiana.
A highly eclectic choir gives everyone the opportunity to express 
themselves.

In addition, there are urban dance classes, numerous programs and 
projects related to the environment, space, health and so on.
Another peculiarity is that a school for parents has been in place since 
2011.

For the liaison with the ISS, the pupils will travel 1 hour of canoe 
motor and 3 hours of road.

*  A direct contact via AA4UT with students at the Student Space 
Technology Association, Knoxville, TN, USA  will be rescheduled.

The University of Tennessee Knoxville is an amazing school located in 
the hills of Tennessee. It is the largest campus in the state, hosting 
more than 30,000 students. This school is known for its engineering and 
science heritage, having close ties with research facilities such as Oak 
Ridge National Lab and companies like Alcoa. Also, included in our 
alumni are 9 astronauts including the recent ISS inhabitant Scott Kelly. 
Our school is filled with thousands of eager students seeking to pursue 
careers in the space industry. With our vision of becoming a top-tier 
research school, our students are set to become the next leaders in STEM 
industries.

Message to US Educators
Amateur Radio on the International Space Station
Contact  Opportunity

Call for Proposals
Proposal Window February 15 ?  April 15, 2017

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with 
a crew member on board the ISS.  ARISS anticipates that the  contact 
would be held between January 1, 2018 and June 30, 2018. Crew 
scheduling  and ISS orbits will determine the exact contact dates. To 
maximize these radio contact opportunities, ARISS is ;
looking for organizations that will draw large numbers of
participants and integrate the contact into a well-developed education
plan.

The deadline to submit a proposal is April 15,  2017.  Proposal 
information and documents can be found at
www.arrl.org/hosting-an-ariss-contact.

The Opportunity
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are 
approximately 10 minutes in  length and allow students to interact with 
the astronauts through a question-and-answer session.

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford education audiences 
the opportunity to learn firsthand from astronauts what it  is like to 
live and work in space and to learn about space research conducted on  
the ISS. Students also will have an opportunity to learn about 
satellite  communication, wireless technology, and radio science. 
Because of the nature of human spaceflight and the complexity of 
scheduling activities aboard the ISS,  organizations must demonstrate 
flexibility to accommodate changes in dates and  times of the radio contact.

Amateur Radio organizations around the  world, NASA, and space agencies 
in Russia, Canada, Japan and Europe sponsor this educational opportunity 
by providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via 
Amateur Radio.
In the US, the program is managed by AMSAT (Radio  Amateur Satellite
Corporation) and ARRL (American Radio Relay League) in partnership with 
NASA and CASIS (Center for the Advancement of Science in Space).

More Information
Interested parties can find  more information about the program at
www.ariss.org and  www.arrl.org/ARISS.

Help Wanted - Russian Space Agency

If you know what this means, "Mukhnem na Lunu: Rossiya
ishchet novykh kosmonavtov"*, you may be able to apply
at Russia's space agency, who on Tuesday announced a
recruitment drive for young would-be cosmonauts who it
hopes will become the country's first on the Moon. And
women are welcome, an official stressed.

In the first such drive for five years, Roscosmos space
agency said it is looking for 6 to 8 cosmonauts who will
operate a new-generation spaceship now in development and
"will become the first Russians to fly to the Moon".

The full story is posted at:

Subject: [amsat-bb] Hard times for satellite radio buyers?
Message-ID: <CY1PR0101MB1050A87D5C02CBB23D0E8962983B0@CY1PR0101MB1050.prod.exchangelabs.com>

Hello all,

Is it not hard times for new and prospective satellite operators (like 
me) in terms of equipment choices, at least in terms of the "big three"? 
(And, to be clear, I'm talking about current, in-production models only.)

I'm looking for an HF base/mobile radio, and also a VHF/UHF-only 
all-mode base/mobile radio that I can use for the linear satellites but 
- wait - there are no VHF/UHF-only all mode radios! That means I need to 
buy a "shack in a box" but - wait - there are only two choices (at what 
I will call moderate prices), the ancient TS-2000 and equally ancient 
FT-857D. There is the new and somewhat more expensive FT-991A and, 
although that sounds like a very good radio, for HF at that price point 
I might prefer the IC-7300 but that would mean no satellite work.

I'm also looking for a portable HF QRP radio, and a portable radio I can 
use for the linear satellites. Again the venerable but ancient FT-817ND 
is pretty much the only game in town. As with the HF base radios above, 
if I am only interested in HF QRP I would probably rather put my money 
toward a KX2 or KX3 of newer design but, again, that would mean no 
satellite work.

So as a new operator, to get into linear satellites it seems I am forced 
to either (1) troll the swap meets for ancient gear; (2) buy new gear of 
old design (which in my mind is even worse); or (3) buy new gear of 
modern design that works for satellite and HF, but is not necessarily 
the radio I would choose for HF alone.

I should add that the situation is not much better for HT/mobile radios 
for the FM satellites, but at least there are some cost effective 
workarounds including the less expensive Baofeng/Wouxun/Tytera radios 
and their clones.

Thanks for indulging my shopping frustrations, and my inexperience, but 
I have to think there are others new to the hobby that are having 
similar thoughts. Do Amsat members see this as a problem?

Probably off to spend some new money on an old radio...

Well Ken I am of the same thinking but a bit different.  I have an old 970 and it 
works great for the birds, but like to do some EME as well at 23cm.  The field is 
like you say do it all or nothing.  The 9100 is nice but has HF in it. and looks 
real small sitting next to my 7700 HF rig.

I bet the next rigs will be SDR driven and the size of your phone........

I have a pair of old Landwehr RF switched receive pre-amps (one 2m and one 7cm) taking up space in my basement. They were working when removed from service about seven years ago, but they have been sitting around a long time and I have no means of testing them at the moment. Strictly "as is." They *DO* have the rare power/control cable connectors with them. 
 
Contact me off list if you are interested in making a deal on these.

Hi Ken,

Welcome, and glad you've found fascination with the Amateur Satellites

Theres always the opportunity to acquire gear from a fellow satellite
enthusiast which you can inquire with folks here on the BB (I've got no
surplus gear right now)

Check out how many all mode rigs are available if you recognize them,
they're often inexpensive if you find them on a hamfest table:


http://www.rigpix.com/index.shtml


There's lots of fun to be had on the satellites, I look forward to hearing
you on the air !

(BTW, even the most modern gear by any definition can only make "Ancient
SSB" sound so good)

One thing I always try to do when I'm at a hamfest and a manufacturer is
present is to mention the features I want on a radio. In my experience I
have found that that they will listen when I say that I want a 2m/70cm full
duplex SSB radio, and often say that they have heard other operators say
that they want those features. But when I mention the word "satellite" they
immediately brush me off by saying that it is just a niche area of the
hobby.

I always encourage hams to voice their frustrations with the manufacturers
in not being able to find a radio today that will really do what we need.
If everyone continues to bug them at places like Dayton perhaps one day at
least one manufacturer will listen and help us.

It's problematic now to be sure. You buy old or you buy the THD-72 from
Kenwood.

But the "big three" are going to be ignored in the end. They don't support
us now and the future will be twenty dollar modules from Amazon plugged
together with a Raspberry Pi to give us the sort of functionality we need
to work future payloads.

Perhaps they understand that and have written this facet of the hobby off
entirely?

I use AWGPE to connect my Mobilinkd Bluetooth TNC to UISS.

Haven't used the Kam TNC but here's a link that might help in connecting it
to AWGPE:

Okay that's what I wasn't sure of. I've only ever used UZ7HO
Soundmodem with UISS. I guess AWGPE acts as an interface between the
hardware TNC and UISS. UISS directly doesn't interface with a hardware
modem AFAIK.

Let me add a vote of support to this idea.  Like Steve, I have been 
talking with vendors for a while now, at places like Dayton.  I have
gone to my favorite company, ICOM, every year now and asked about all
sorts of things like weak signal equipment, the lack of 222Mhz gear,
lack of multi-band HTs like the ic-T81a, etc.

Only when politely pummelled with queries will they think about 
changing.  I'm sure that the big three are very nervous about the future 
with Chinese companies making inroads with usually checp not
great products, but if they don't don't offer what people want, they
will die.  It will be interesting to see what Chinese ham companies
do in the future.

Lastly, try to influence American companies to make ham gear.  I am
thankful for Elecraft and Ten-Tec and hope there will be more. There
should be.   Not disparaging the kit-based SDR people--they're great
but I think there is room for all.

Ken,

I too wish for a V/U purpose built rig and in particular a portable one. A rig with dual VFOs and full duplex capability. I don't see this type of rig offered from the "Big 3" anytime soon. 

I think instead of everyone trying to get them on board, we should pursue the smaller manufacturers. I see these Xiegu HF rigs and they look pretty nice. My guess is a company like this has facilities to produce a nice, modern sat rig. Perhaps we should send our votes of support to a company that would cater to a niche market.

As far as ancient tech goes, I think it still works pretty good. Used two 817s to work Russia from a park in LA county about a week ago on AO-7, launched back in 1974. It's not the most ideal rig but it can still get the job done.

Ettus B210. Tested with another radio as the uplink. Blasted away with
50 watts (accidentally) and the B210 didn't complain (or croak).

It has other advantages, as it's rx goes out to 6 GHz.

The amps/control hardware need way more testing before cabling all the
stuff together and trying it out. Creating a smoking pile of junk
makes me want to cry. No oopsies so far.

Computer control (using windowz) is a nightmare due to lack of support
for the B210. Lots of promises. No one has delivered. There is a Linux
solution. The dark side beckons.

Simple enough amplifier circuitry. Biggest wow was the amount of heat
produced (wasted power). Fans, heat sinks, power supplies with
regulation and filtering....

Test setup is runs from +24VDC battery stack (D cells) using surplus
power bricks. Lots of documentation on how to make them RF quiet.

The down side of these bricks is that for them to meet spec, there
must be a minimum load.

Currently portable with an 857d and an IC 7000.

The longer a product is produced, the more spare parts available and
the better the support (most of the time). The 857d is a great radio.
Strapping two together would make a great station. Much to be said for
this approach.

When you step back and look at the state of the satellite transceiver
market, it's not all that different from the 1990s. The difference is that
Yaesu doesn't produce one, otherwise each of the "Big 3" have only produced
one model at a time. The other difference is that both the Icom IC-9100 and
Kenwood TS-2000 are "shacks-in-a-box" which increases costs for those who
already have or don't want HF capability. The TS-2000 is also lacking
because of its birdie on the SO-50 downlink frequency which prevents me
from ever recommending it.

The other downside is that both of those options are not exactly "field
friendly." The Icom IC-820H, 821H, 910H, and Yaesu FT-847 are all small
enough to be used in the field. Many have remarked that the Icom IC-910 and
an Arrow antenna is the simplest and best performing portable satellite
station available. These transceivers are not to difficult to find on the
used market, but the prices can be a bit high owing to continued demand.

If you want to buy new equipment for the field, Norm's suggestion of two
Yaesus is not a bad one. Dual FT-817s are very commonly used. NJ7H has used
his "FT-1634" to activate 250 grids and 7 DXCCs on satellite over the past
year. I use a "FT-1634" plus a small dual band amplifier (a Microset
VUR-30) and preamps for a well performing portable setup. Others have used
the "FT-1674" (a Yaesu FT-817 and FT-857 combo) with great results. The
downside is that you often need filtering to eliminate desense between the
two radios. A common diplexer such as those made by MFJ or Comet works for
this purpose.

As suggested, the future lies in the SDR realm. At the present time, these
solutions are not ideal for the field. Many have used SDRs such as a
FUNcube Dongle or SDRPlay as their downlink receiver paired with an
all-mode transceiver for the uplink. Properly configured, this can work
very well, but use in the field can be difficult due to glare on laptop or
tablet screens. Many have used this type of setup with great results in
home stations. Another downside is SDR processing delay and its
difficulties with full-duplex operation, but this can be mitigated with
more efficient programming and/or more processing power.

When it comes to a full SDR transceiver setup, as Norm suggests, this is
doable today. While Flex no longers offers the Flex 5000 and V/U modules,
there are other options that could work quite well. The downside is that it
is not "plug and play" at the moment, you need to add filtering and
amplification to the available SDRs. I don't think any user friendly
software exists at the moment either, but there is definitely an
opportunity there.

The AMSAT Ground Terminal team is working on a full SDR based ground
terminal for use with digital 5 GHz uplinks and 10 GHz downlinks, to be
used with a number of future AMSAT satellite projects/payloads in GEO, HEO,
and beyond.

When you consider all the options, there are likely more options for
getting on the satellites today than have existed in the past. There might
not be as many plug and play boxes available from major manufacturers, but
there are lots of ways to build a ground station for home or field use, and
ways to do that to meet almost any budget.

73,

Paul, N8HM

Talk to the guys at Flex :) 

They are participating in the Phase 4 ground station work and they know who we are.  

Then again, they know who we are (grin)

Yup, had one here for a month now. Paper written for the Eastern VHF/UHF 
Conference coming in April - plus a Presentation on the LimeSDR on 
VHF/Microwave.

Bottom line - for satellite use, possibilities, but not ready yet.

I have a pair of old Landwehr RF switched receive pre-amps (one 2m and one 7cm) taking up space in my basement. They were working when removed from service about seven years ago, but they have been sitting around a long time and I have no means of testing them at the moment. Strictly "as is." They *DO* have the rare power/control cable connectors with them. 


Contact me off list if you are interested in making a deal on these.

Hi all,
I have some time, so heading over to EM85 to catch the SO-50 pass at 2114z to fulfill a request. The pass doesn't cover the west coast, sorry; might try a pass favoring that side of the country another day. Could be some other activity on from the Gulf of Mexico or the Yucatan, so patience as always will be key. I'll do my best to work everyone that needs the grid, but we all know how it can go.

Looks like my TS-2000 needs to go back to HRO for warranty service. I have no problem on FO-29 with the 2 meter uplink and 70cm downlink, but reversed for other sats I get a cw message ?(UL) PLL Unlock and rig goes dead with dashes on screen. After turning the rig off and on again it comes back to life. But as soon as I transmit on 435mhz again, it cuts out. No problem transmitting on 2 meter uplink. Anyone else experience that with their TS2000?

My setup is a Kenwood TS-790A, preamps at the antennas for both 2 meters and 70 cms. powered through a separate control line (not via coax) and some M2 antennas (pictures and more details at my QRZ page: HERE <https://www.qrz.com/db/KF4FC>).  I have a sequencer with up to 5 control points available.  It seems that our implementation for sequencers is a bit different that most applications in that we have the possibility of needing to:

> B) Transmit on 70 cms while listening on 2 meters. i.e. 2 meter preamp on, 70 cm preamp off

> and this can change rather rapidly if multiple opportunities for passes are close.  The way I am operating now is that I selectively turn on the preamp that I  need for each pass and turn the other off.  This is working, but even though I have rf sensing preamps, I do not want to chance transmitting SSB into either preamp.  I am only transmitting 30 watts maximum and usually significantly less.

> The Kenwood TS-790A has an ?External Connector? on the back where I can access the PTT as well as having pins that can tell me when either 2 meters or 70 cms are being transmitted.  All this said, it seems that I am in a bit of catch 22 because even though I can separate the PTT and for instance use a foot pedal to trigger the sequencer, the pins on the back of the rig will only change their signal AFTER the transmission has already started, so this signal is not helpful to determine which preamp to turn off and which to turn on.  I realize that I could have a manual switch to go back and forth between using 2 meters and 70cms but that is essentially what I have now.  
> 
> I am sure that I am missing something that somebody out there will suggest is very obvious.  Help me understand how to implement a sequencer when we have two frequencies that can be in use at one moment in time and easily switch the next pass in an effort to make the station bulletproof so that I don?t blow up preamps.

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.

Hello all,

Thanks for all the helpful comments on my earlier post!

Several folks mentioned the IC-9100 which looks like an excellent radio. I left it off my list only because of the higher price-point which makes it less approachable for some. Likewise with Flex. I wonder if ICOM will offer some deals on the IC-9100 soon, when the IC-7610 comes out? It seems they will compete at the same price point.

The points on SDR as the future are well-taken, but sometimes it's nice to simply turn on a device and just have work, without fussing about with computers and software (and I'm an IT guy, which is perhaps all the more reason I think that way). I look forward to acquiring that elusive VHF/UHF all-mode radio (even if it is an "ancient" one). ;-)

Thanks again & 73

Hello all,

Is it not hard times for new and prospective satellite operators (like
me) in terms of equipment choices, at least in terms of the "big three"?
(And, to be clear, I'm talking about current, in-production models only.)

I'm looking for an HF base/mobile radio, and also a VHF/UHF-only
all-mode base/mobile radio that I can use for the linear satellites but
- wait - there are no VHF/UHF-only all mode radios! That means I need to
buy a "shack in a box" but - wait - there are only two choices (at what
I will call moderate prices), the ancient TS-2000 and equally ancient
FT-857D. There is the new and somewhat more expensive FT-991A and,
although that sounds like a very good radio, for HF at that price point
I might prefer the IC-7300 but that would mean no satellite work.

I'm also looking for a portable HF QRP radio, and a portable radio I can
use for the linear satellites. Again the venerable but ancient FT-817ND
is pretty much the only game in town. As with the HF base radios above,
if I am only interested in HF QRP I would probably rather put my money
toward a KX2 or KX3 of newer design but, again, that would mean no
satellite work.

So as a new operator, to get into linear satellites it seems I am forced
to either (1) troll the swap meets for ancient gear; (2) buy new gear of
old design (which in my mind is even worse); or (3) buy new gear of
modern design that works for satellite and HF, but is not necessarily
the radio I would choose for HF alone.

I should add that the situation is not much better for HT/mobile radios
for the FM satellites, but at least there are some cost effective
workarounds including the less expensive Baofeng/Wouxun/Tytera radios
and their clones.

Thanks for indulging my shopping frustrations, and my inexperience, but
I have to think there are others new to the hobby that are having
similar thoughts. Do Amsat members see this as a problem?

Probably off to spend some new money on an old radio...

Maybe the new radios of old design are still on the market because there is
nothing wrong with their design and they still work well.  Newer doesn't
always mean better.

An International Space Station school contact has been planned with participants at "School of Trois Paletuviers", Saint-Georges de l'Oyapock, French Guyana on 23 Mar. The event is scheduled to begin at approximately 12:42 UTC. It is recommended that you start listening approximately 10 minutes before this time.The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and W6SRJ. The contact should be audible over the west coast of the U.S. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English.

 

 

Inventory

Trois Pal?tuviers is a small Native people village of French Guyane, set between the Amazonian forest and the majestic Oyapock River, natural border with Brazil. It is accessed only by dugout and the journey takes place in one hour. On site, no electricity during the day, internet and telephone recently; But a quality of life preserved; Which in no way excludes projects and achievements in order to help envisage the future in a dynamic and optimistic way.The village comprises a population of 180 inhabitants, exclusively Native Americans and many of whom have strong ties with Brazil.

 

A dynamic The school hosts about fifty students divided into 2 classes: 

A kindergarten from the PS to the GS, an elementary from the CP to the CM2. 

In addition to the usual teachings, the school offers activities that enable you to travel and make contact with the outside of the village. 

So : The "chess game for academic success" has been helping since 2006 to reason and confidence in its abilities, The theater club has already performed several times in French Guiana. A highly eclectic choir gives everyone the opportunity to express themselves. In addition, there are urban dance classes, numerous programs and projects related to the environment, space, health and so on. Another peculiarity is that a school for parents has been in place since 2011.

 

For the liaison with the ISS, the pupils will have 1 hour of canoe motor and 3 hours of road.

About ARISS: 

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and  National Aeronautics and Space Administration (NASA).  The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues.  With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums.  Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.  For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.

 

Thank you & 73,

I posted this a couple of weeks ago on a Friday and it didn't get a
lot of views possibly because "Fridays are slow news days." I got
permission from the amsat-bb list owner to repost it.

It's a pretty cool video where I got a French student to translate a
French astronaut's answers to students in Belgium. The contact was
through K6DUE telebridge station in Maryland, which is why we were
able to hear the ISS talk to a school in Belgium from North Carolina.

Hello all, The suggestions in this thread omitted some current Yaesu 
models, specifically th VX-8DR, FT-1XDR and FT-2DR. Are these not viable 
in-production options, in addition to the Kenwood TH-D72? Or were they 
omitted from the earlier suggestions because perhaps they don't offer 
built-in TNC capability? They claim to offer dual-band 
simultaneous-receive capability at least.

Just reading up on EO-79, trying to understand it.  The Amsat website 
says:  "The transponder will commence operation 27 minutes after the 
spacecraft enters sunlight and will stay on for a period of 25 minutes."

I take that to mean that the transponder will stay ON for 25 minutes 
regardless of whether the satellite is in sunlight or darkness during 
that 25 minute period.  Is that correct?

I also read:  "This schedule may be modified over the forthcoming weeks 
as a result of experience."

Have there been any changes to the schedule?

Hi Ken.   You are correct.

Exits eclipse into sunlight with transponder off.
counts 27 minutes -This is over Antarctica and the southern Ocean, so not many users. - Battery charging.
Switches on transponder.
After 25 minutes of transponder operation it switches off.
Then it has a short period in sunlight to add a little charge to the battery
Enters next eclipse.

Since implementing this schedule it has not been modified.
We continue to monitor the orbit / the coverage area of the satellite and the power budget as the seasons change.

So far.....so good.

I had the satellite schedule app on my Kindle and it gabolled. Of course I  
didn't write it down. It's the one from LU?- that ties to the Amsat  
predictions  but is a one page sheet with maps/ frequencies and AOS/LOS  times/ 
azimuths. - I loved it for the ability to have it on my KINDLE, small  
portable, easy to use and read. 
Would someone send me the link info please

Hi all-
LoTW TQSL Config File V11.0 was released today. Among other things, it adds EO88 (Nayif-1) to the satellite list.
You should get a popup window announcing the new config file the next time you open TQSL.?Sean Kutzko Amateur Radio KX9X

Douglas,

You can borrow mine for a while, does that do any good?  I'll need them
back by August 1.

Priority mail about $10, the 2015 is a fat book!

Or, are you looking for a specific article(s)?  If it's Fox ITAR I would
have it else Dan Schultz might still have the original pdf for other
submissions.

FYI -

It is formatted for the correct OSCAR name (EO-88) in the new v11.0 
configuration file. Therefore if you are using something other than ARRL 
TQSL to generate the ADIF, you will need to enter EO-88 as the satellite 
name.

Having used all three, they do not offer full duplex capability. However, they do have good receivers, and could be used with a separate transmitter to operate full duplex.

All three also DO have a built in TNC, and work well for APRS.

Hello everyone,

I just got a couple crossed dipoles, one VHF, the other UHF, for some
satellite work.

How far apart should they be for proper operation and minimal influence on
each other?

I remember reading somewhere that it should be one wavelength of the lowest
band, in this case, two meters.

Thoughts?

Thanks

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.  

For proposal information and more  details such as expectations, proposal 
guidelines and proposal form, and dates  and times of Information Sessions go 
to  http://www.arrl.org/hosting-an-ariss-contact.  
Please direct any  questions to  ariss at arrl.org.

Hello fellow bird talkers,

As is usual, I will be venturing on a roving trip this weekend departing
tomorrow (hooray for a random three day weekend). The plan is to head to
the Detroit/Windsor area. Because I can't resist crossing international
borders, expect to hear NJ7H/VE3 at some point, hopefully with a terminus
of EN92 or EN83 this trip.

I'll try to hit as many new /r grids in MO, IL, IN, MI as time allows, but
as usual I'll expect to be in a good time crunch on the way home. Skeds
available, hit me up on Twitter or email for whatever you need. I'll try to
be on general good passes (AO-7, FO-29, FM, good full continent stuff).

Feel free to watch my every movement on APRS NJ7H-9, or when that doesn't
work I can still be watched and harassed via iridium share.garmin.com/gz.

Have fun, and keep the power down.

Hi Ken,

I use a FT-2DR as TX for FM satellites. It has simultaneous receive, but
it can't TX and RX simultaneously, so you would need a second radio to
do full-duplex.

For me the FT-2DR works fine, but I wouldn't recommend it if you're
picking an HT for satellite use only (because it's expensive and most of
the extra features are useless for satellite). Also, the VFO can only be
tuned in 5kHz or 12.5kHz steps, which is a bit inconvenient (no 2.5kHz
steps).

73,

Dani EA4GPZ.

On AO-85 at 12:55 UTC today I managed to contact three members of the
Texas DXpedition team in YN2/Nicaragua. They are in country for the
upcoming CQWPX Phone contest.

The bird was very high on them before they were able to get into the
satellite but I managed to work three team members: YN2KW, YN2MG, and
YN2MF. They were weak so you will need to have good ears to pick them
out on AO-85. I believe they have an HT and Arrow.

Message-ID: <7CEE4D021C4647058D1130D57C86238C@allgood.local>

Hi folks,

FUNcube/AO73 is now in full time amateur mode with the transponder ON. The 
plan is for it to switch back to auto mode on Sunday pm UTC as usual.
Please see below for other FUNcube transponder info

Have FUN with the transponder.

73s Graham G3VZV and the FUNcube team.

++++++++++++++++++++++++++++++++++
FUNcube frequencies and other details
++++++++++++++++++++++++++++++++++

AO-73 FUNcube-1

The transponder is normally operational only when the satellite is in 
eclipse, ie the solar panels are NOT being illuminated. During weekends 
(from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.

When the transponder is switched off, the telemetry beacon is on full power, 
when the transponder is on the beacon it is on low power. During holidays, 
eg Christmas, New Year, Easter, etc, the transponder maybe activated for 
extended periods. Watch AMSAT-BB for announcements which are usually made on 
Friday evenings (UTC)

The nominal transponder frequencies are:

Uplink:   435.150 - 435.130 MHz LSB (Inverting)
Downlink: 145.950 - 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK

(The passband may be up to 15kHz higher depending on on-board temps. Lower 
temperatures give higher freqs!)

FUNcube-2 (aka FUNcube on UKube)

The FUNcube-2 sub-system continues to operate autonomously and, almost 
continuously, in amateur mode. The transponder is operational and the 
telemetry downlink is functioning with about 70mW output. The FUNcube-1 
Dashboard does not correctly display the telemetry but it does correctly 
decode the data and uploads it to the FUNcube Data Warehouse from where it 
can be examined. Most of the real time data channels are operational and 
these include battery voltages, temperatures and ADCS data coming via the 
main On Board Computer (OBC).

The transponder is interrupted for a few seconds every 2 minutes when the 
other transmitter sends its CW beacon and, occasionally, for a few seconds 
when the main OBC reboots (approx seven times each orbit).

The nominal transponder frequencies are:
Uplink:   435.080 - 435.060 MHz LSB (Inverting)
Downlink:   145.930 - 145.950 MHz USB
Telemetry Tx: 145.915 MHz BPSK

(The passband may be up to 10kHz higher depending on on-board temps. Low 
temperatures give higher freqs!)


EO79 FUNcube-3
Due to power budget constraints the transponder cannot be operational 24/7 
and an orbit specific schedule has been developed. The transponder will 
commence operation 27 minutes after the spacecraft enters sunlight and will 
stay on for a period of 25 minutes. This schedule may be modified in the future 
as a result of experience.

The nominal transponder frequencies are:
Uplink: 435.0723-435.0473 MHz LSB (Inverting)
Downlink: 145.946-145.971 MHz USB

Further detailed info on EO79 transponder frequencies is at:
https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/


EO88/Nayif-1/FUNcube-5

EO88 is presently operating in autonomous mode. The transponder is 
operational when the satellite is in eclipse, ie the solar panels are NOT 
being illuminated.
When the transponder is switched off, the telemetry beacon is on full power, 
when the transponder is on the beacon it is on low power.
The transponder frequencies are:

Uplink:  435.045 ? 435.015 MHz LSB (inverting)
Downlink: 145.960-145.990 MHz USB
Telemetry  Tx: 145.940MHz

All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very 
grateful for the assistance given by Innovative Solution In Space Bv, The 
Netherlands.

Message-ID: <CAPovOwdhgaY1k=rSN5HdqmpsqEs7kAQ-zH7fg0+7riRM3E5ULQ@mail.gmail.com>

I happen to be a fan of using Software Defined Radio (SDR) to receive
amateur satellites. It is an inexpensive way to view all the signals
appearing on a satellite's passband simultaneously.  While I don't
normally run SDR full time at my station, from time to time I use it
to monitor activity on busy satellite passes because I can view and
record all activity.

As a result of more people using SDR on satellites, I have discovered
an operating trait that warrants some discussion and evaluation.

On more than one occasion, I have given a call to a very specific
station, and instead of my intended target had another SDR-based
station appear on frequency immediately saying "QRZ? QRZ?" rather than
wait and listen to who is calling on the frequency. The SDR user saw a
signal on their waterfall and clicked on it. They "pounced" on what
they perceived to be another station looking to make contact which
might not necessarily be the case.

I've see the same thing happen a few times with pileups.  There is an
existing pileup in progress when the SDR station comes into the
footprint. Rather than wait a short period to listen, they click on
the new signal in their waterfall, and immediately proceed to "QRZ" on
the frequency of the pileup, sometimes interrupting the flow of
existing contacts.

Just today I heard this scenario: Station 1 calls CQ.  Station 2 went
to answer. The SDR user clicked on the waterfall, heard only part of
the callsign of Station 2, and proceeded to call Station 2, ignoring
the possibility that Station 2 was attempting to QSO with someone
else.

It seems to me the visual nature of SDR waterfalls is causing a
temporary lapse in judgement when it comes to a basic ham radio
principle that we apply to satellite operating -- listen with our ears
before transmitting.

SDR is a great listening tool. With great power comes great responsibility.

Was  on the 18:55 UTC pass of EO-79. Signals very strong however there were no other stations heard during the complete pass. Was wondering why other people are not utilizing this satellite ?? Are they afraid of manual tuning of the Doppler or is it just too difficult for them to keep up with the Bird ?? even though it is hard to track and maintain Doppler it is still a great satellite to work, Nice footprint and strong signals. Was on the satellite many times in the past with same results.. Nobody heard !!   JACK-KC7MG  DM42

Clayton,

Good topic!

I would suggest that this behavior is not confined to SDR or satellite 
QSOs, but pervades all modes and bands of our hobby. I am guilty of 
this, but more due to excitement than intention. The good advice that is 
not confined just to ham radio, listen first, listen again, always 
applies, or as one local ham suggests, put mind in gear before the 
mouth. Not to sound like Miss Manners, but perhaps one of the unique 
aspects of our hobby is to always be considerate of the other operators. 
I always appreciate those ham's who mentor by example with kindness and 
absence of judgement.

Thanks for mentioning!

Whether tuning blind or with full SDR vision, transmitting without listening to assess the situation is massively counterproductive. As noted, it disrupts the on-going communication and isn?t any more likely to get a response. HF, VHF, or SATs it all works the same.

AMSAT Fox Series Launch Schedule Update

The launches of AMSAT satellites Fox-1Cliff and Fox-1D have been 
rebooked from
the original Spaceflight Formosat-5/Sherpa mission aboard a SpaceX 
Falcon 9  on
to two separate new launches.

Fox-1D will now ride to orbit on an Indian PSLV vehicle scheduled to 
launch from
Satish Dhawan Space Centre in Sriharikota, India in late 2017.

Fox-1Cliff will launch on Spaceflight?s SSO-A dedicated rideshare 
mission aboard
a SpaceX Falcon 9 scheduled to launch from Vandenberg Air Force Base in
California in late 2017 or early 2018.

These moves will serve to expedite the launch of these two satellites, 
both of
which carry an amateur radio U/v FM repeater and an experimental L/v FM
repeater.  The satellites also carry scientific experiments, from 
university
partners Penn State, Vanderbilt University ISDE, Virginia Tech, and 
University
of Iowa.

In addition to the launch of Fox-1Cliff and Fox-1D, AMSAT is awaiting the
launches of RadFxSat and RadFxSat-2. RadFxSat is currently manifested 
for launch
on August 29, 2017 aboard the ELaNa XIV mission, as a secondary payload 
with the
Joint Polar Satellite System (JPSS)-1 on a Delta II from Vandenberg Air 
Force
Base, California. RadFxSat-2 will be launched by Virgin Galactic on their
LauncherOne air launch system from Mojave, CA on the ELaNa XX mission no 
earlier
than December 2017.

ND9M Satellite Gear in VQ917 Chagos Islands

VQ917, CHAGOS ISLANDS. Jim, ND9M (VQ96JC), from Diego Garcia Island
(AF-006) informs OPDX on March 14th, "Well, the local licensing office
came through for me again. The VQ917JC license I asked for just came
through here this afternoon." So start looking for Jim to be on the air
signing as VQ917JC. Jim told OPDX he will not make an effort on 60m at
this time. His operating hours are still limited to 1200-1600z max which
doesn't do much good for the NA/SA ops. He states that he will probably
focus on 30, 20, and 17 meters just to get VQ9 into some logs. Jim also

Ex-Alta-1 Alberta Canadia Cubesat Set to Launch

Ex-Alta-1, the first CubeSat satellite mission from the University of 
Alberta?s
AlbertaSat team, is set to launch on an Atlas V rocket from the Cape 
Canaveral
Air Force Station in Florida. The launch will be streamed via NASA Live 
and the
United Launch Alliance.

The cubesat will make a brief pit stop aboard the International Space 
Station
before being deployed into low Earth orbit to begin monitoring space 
weather.
Ex-Alta-1 is part of the international QB50 project, which involves 
cubesats
designed and built at universities around the world, representing 15 
countries
from five continents. The cubesats carry complementary science payloads 
that
will study space weather and the lower thermosphere for a period of nine 
to 18
months.

After seven years and countless hours contributed by more than 50 team 
members
(including undergraduate and graduate students as well as faculty members),
measuring roughly the size of a loaf of bread and built with financial 
support
from more than 600 crowd-funded donors as well as the Canadian Space 
Agency, Ex-
Alta-1?s launch marks the beginning of a new era of space exploration for
Alberta. Not only did the team build the first ever made-in-Alberta 
satellite,
AlbertaSat is also one of the first Canadian universities to put a 
satellite
into space.

The University of Alberta participated in the first Canadian Satellite 
Design
Challenge (CSDC), prior to focusing its efforts on the QB50 mission, and 
many
members from the Ex-Alta-1 team are competing in the current CSDC. On 
behalf of
the Canadian Satellite Design Challenge, and all the teams participating, I
would like to send my congratulations to the entire AlbertaSat team, and 
hope
that the launch, deployment, and mission of the Ex-Alta-1 cubesat will be
successful.

The Ex-Alta 1 Satellite has the following science objectives:

1. Serve as a platform for the In Orbit Demonstration (IOD)
of a digital fluxgate magnetometer designed at the University
of Alberta.

2. Address multi-point space plasma physics with data from
the QB50 constellation using the Langmuir probe common payloads
and the digital fluxgate magnetometer.

3. Take part in the QB-50 string-of-pearls constellation for
in-situ measurements of the lower thermosphere to build an
accurate model.

A downlink of 436.705 MHz has been coordinated employing
9k6 GMSK using the published Cubesat Space Protocol and the
QB50 whole orbit data specifications.

I'm looking for a filter suggestion to reduce the third harmonic (435

a simple 435MHz quarter wave stub?

Thanks

The first question I would ask is if 100w is really necessary. After that, you may want to look into using a diplexer as a low pass filter or find a dedicated 2m LPF.

You might find a surplus commercial 160 MHz Low Pass Filter in the used
market.  That would work just fine for what you are looking for.  I also
like Mike's idea of using a duplexer like the Diamond MX-72H.  The unused
port will need to be terminated with a 50 ohm dummy load.

A mobil diplexer will give you 60 dB of isolation between uhf and
vhf.should be more than enough even at 100 w.I have used them with both the
Ft847 and IC 910 with zero desense even when using gaasfet preamps at the
antennas on both bands.

Paul,
As mentioned, you can use a commercial diplexer, or split it by making yourself a lpf for 2m
and a hpf for 70cm,easy and cheap.

	Los Angeles, CA
Message-ID: <615B6A0CFA704CA5AAED7B568BC5F884@DHJ>

An International Space Station school contact has been planned with participants at Council of State Science Supervisors, Los Angeles, CA

on 29 Mar. The event is scheduled to begin at approximately 18:03 UTC. It is recommended that you start listening approximately 10 minutes before this time. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between OR4ISS and IK1SLD. The contact should be audible over Italy and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English.

 

 

The Los Angeles Unified School District: Local District South, Los Angeles, California

at

The Council of State Science Supervisors (CSSS) Annual Conference, Los Angeles, California

 

CSSS is the only professional science organization whose members have direct accountability to the state government agencies given the constitutional authority for education. Each of these supervisors plays a key role in directing efforts at improving school science and ensuring excellence and equity in science education in their states.  This partnership with ARISS is a way to showcase the importance of space education and create enthusiasm among state leaders that can be shared with teachers across the nation. CSSS partnered with students from the Los Angeles Unified School District, The Jordan-Locke network comprised of 16 elementary schools for this event. Participants in the ARISS contact include 6th grade students from the 92nd, 93rd, and 96th elementary schools.  The District demonstrates that all children can achieve their highest potential when the conditions for learning are at an optimum by integrating project based learning into the academic achievement of students in all subjects. All schools are located in Watts or South Central Los Angeles and consist of a predominantly Latino and African American Student population with poverty rates in the 95-100%

 

 

 

Participants will ask as many of the following questions as time allows: 

 

1. In Science class we learned that it takes a tremendous amount of energy 

   and speed to escape Earth's gravity. Can you tell us how you felt as you 

   were climbing upward through Earth's Atmosphere? 

2. Reentering Earth can be very dangerous for astronauts. Can you please tell 

   me what steps do you follow when reentering the Earth's atmosphere?

3. In Los Angeles, there are many street lights at night that prevent us from 

   seeing many stars in the sky, but when we went camping in the mountains we 

   saw more stars.  Now that you are in space, can you see     even more 

   stars than we see here on Earth?


4. In Science class we are learning about germs and how fast they can spread. 

   Do germs multiply as fast in space as they do on Earth?

5. Is there something in space that you did, that you will never forget?

6. Were you afraid to go to space?

7. Is there a problem with space junk? If so how severe is it?

8. What is your purpose for being in space today? 

9. We know that in space there is zero gravity. What is the proper procedure 

   for eating in space so that your liquids or food does not float away or 

   damage any equipment?

10. What activity do you like doing the most while in space and why?

11. How hard is it for you to settle in space, leave your family, and 

    communicate with them?

12. How long does it take to become a professional astronaut?

13. We recently read your biography and noticed that you accomplished so much 

    here on Earth. Can you tell us how your achievements on Earth help you 

    complete your missions on the International Space Station? 

14. Have any of the solar panels on the ISS been damaged by space debris? If 

    so, please tell me how you were able to repair it.

15. If you were stuck in space, what are the 5 most important things you 

    would need to survive? Explain why. 

16. I read that you are very athletic. Have you found any new health problem 

    besides, the weakening of muscles, while living on the International 

    Space Station? 

17. What was the most important/amazing/beautiful thing in space you ever 

    saw?  

18. Have you seen anything in space that scared you or confused you? 

19. Which planets (other than Earth) do you see most often as you are 

    orbiting in the ISS? Do you have a favorite planet? Why is it your 

    favorite? 

20. What is the longest time you have been in space? 

21. What is the most dangerous situation that you have experienced on the 

    International Space Station?

22. What activities do you do while up in space in your free time? 

23. Have you thought of teaching anyone about how to be an astronaut? 

24. Your biography shows that you have such a great life on Earth.  Can you 

    tell us what convinced you to go to space?

About ARISS: 

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and  National Aeronautics and Space Administration (NASA).  The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues.  With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums.  Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.  For more information, see www.ariss.org, www.amsat.org, and www.arrl.org.

The last couple of days EO-88's telemetry has been uplinking to FO-29 in
passes over the US.

I recorded some data being sent via FO-29 today approximately 16:21 UTC.
Very strong signal.

If you skip to about 6 minutes, 44 seconds into this recording you will hear
it:

https://clyp.it/m4lalgl5?token=2c0365f763bcb95a6e42a5d7fe003d6b

Afterwards you can listen to a pileup of stations working UT1FG/MM.

I can email you the MP3 if you'd like.

Perhaps termination would help on the diplexer ... so far, I've kept it
simple and just unplugged the unused antenna on the Arrow. It 'seems' to
work  OK when using the FT-1634.

I would like to get at least one and up to five contacts on the pass. I am
doing the RaDAR challenge from St Andrews State Park at EM70. My first Sat
contact will count as a bonus. Eddie ZS6BNE came up with the RaDAR ideal
and he loves Sats. In Radar, you make five contacts and move. However, I
don't want to interfere with any special operation already scheduled. You
can find info on RaDAR on my web site N4KGL.info Just scroll down.

Thanks,

Greg  N4KGL

Hello everyone,
I also heard the pileup and this data and also asking myself what it was...
Thanks Clayton for record of my audio, nice to see that you have better
return than me :) Still waiting for a little more power out and V/UHF
preamps.

Hello everyone,

I take advantage of this question to ask if you know to increase the limit
of 10 birds on satPC32 to adjust of number of active sats.

Clayton,
Thanks for sharing that recording. It was fun listening to the Yuri-pile!!!
The data signal on your recording did not sound like the signal that would?force me to QSY on several FO-29 passes while I was roving in the?South the last couple of months. Your recorded signal had distinct frames?with what sounded like syncing at the beginning and end. The signal that?QRMed me was continuous once it started and I couldn't make good?QSOs through it.
TNX/73, ? Bob ?K8BL

All,

ITF-2 (YUI-2) entered normal operation phase on Mar 25th JST.
Telemetry information and messages will be transmitted in this phase for
the achievement of main mission.


The details of the AWARD and SWL cards are as below,
AWARD?
With reference to the message on Jan 15th UTC,
the First 100 Reports from overseas stations are qualified for this award.
Only ten overseas stations sent report so far. Still enough award can be
issued.
Additionally, a souvenir, a sticky screen cleaner, will be given with this
award.
The design motif is the small antenna of ITF-2.
Design of the cleaner:
https://twitter.com/yui_tsukuba/status/841096655046758400


SWL cards:
Five designs are prepared. The stations which report more than five times
can receive all designs.
Also, the specially designed card will be presented to the stations which
received a signal from the small antenna,
because the reports are valuable to demonstrate the antenna in space. So
far, two stations succeeded in the reception.
Designs of SWL cards:
https://twitter.com/yui_tsukuba/status/846219342190555136


Futher special events are planned for the promotion of receptions by more
stations.
This will be announced later.


There were some reception reports by very simple equipments,
for example, Dipole or 5/8 wave length whip with USB tuner dongle (RTL2832).
The examples are as follows,
Ex1:https://twitter.com/dspic/status/842000948834717696
Ex2:https://twitter.com/dspic/status/826823146955120640

Reception reports can be submitted at:

Looking forward to reports from more stations.

I actually dug up a Comet CF-4160J Diplexer (both Comet and Diamond call
them "Duplexers") and swept its response with my Spectrum Analyzer, using
the Low-Frequency and Common Port. I was also curious to find out if it
mattered if the High-Frequency Port was terminated or not.

The bottom line is that this particular Diplexer would reduce the 2-meter
3rd harmonic by 55 dB, and had an insertion loss of 0.12 dB.  And I
confirmed that there was a small reduction performance if the
High-Frequency Port was not terminated.

I would expect the performance of Diamond models would be similar and I
will test one when I find one.

The actual report can be found here:  http://wb4son.com/wpblog/?p=2828  (if

Hi!

Another option for diplexers as bandpass filters would be the MFJ
diplexers. I use an MFJ-916B diplexer for my satellite station,
and I saw a test comparing this with a Diamond MX-72 diplexer
that was done a little over a year ago:

http://www.w4gso.org/news/comparing-duplexers-mfj-vs-diamond/

Summary: the MFJ diplexer outperformed the Diamond unit. Also, the MFJ
diplexer costs about half of what you normally see for the equivalent
Diamond or Comet units. And the MFJ-916B is made in Taiwan, not
Mississippi.

73!

Good evening fellow sky talkers and bird trackers,

An exciting trip will occur this weekend with Dave KG5CCI and myself
venturing to the wastelands of the Chihuahuan Desert in New Mexico. We will
be visiting the Trinity Site on Saturday morning (sadly the U.S. Army is
not friendly to operating on the missile range from the actual site).
However, we may still have an opportunity to activate a nuclear test site,
the site of Project Gnome, a 3.1kt underground bomb test.

We will be leaving early morning on Friday 3/31 and will return Sunday.
Grids that can be expected are EM02/03/04/05
DM61/62/63/71/72/73/82/83/84/92/94/95. Watch our Twitter accounts @KG5CCI
and @NJ7H_Radio for updates, one of us will usually be on APRS (I use
NJ7H-9), and iridium at share.garmin.com/gz. QSL via LoTW or direct with
homing pigeon.

Have fun and keep the power down.

73,
Gabe
NJ7H/lunacy

Thanks for that info Bob. Like Patrick, I also use the MFJ Diplexer (and spellcheck likes duplexer too) and have had good success with it. I will be ordering a terminator to correct my laziness (and maybe get a dB or two).

Appreciate your reply,

Doug, N6UA

I too have an MJF I use with my Elk and it performs well. More recently I've been using an arrow with my FT-1634 and had no real problems with desense on Mode J. However, on Mode B I had all sorts of problems. FM wasn't so bad but on AO-7 it was practically useless unless I ran <1 watt. As a test I just threw on the arrow diplexer as an LPF and it gave marginal results. I tried many things to get rid of the problem going so far as to convert my 817's to N type rear connectors, hand built and sweeped a set of jumpers, you name it same problem. Eventually I decided to try a terminated diplexer. Not having anything on hand I desoldered the 70cm pigtail on the arrow diplexer and soldered (2) 100 ohm carbon film resistors in its place. Next AO-7 I gave it a shot and it worked like magic even when I was QRO at 5 watts.

With this lesson learned I believe the need for termination may be poorly represented by a bench test. I think that much of the UHF I was trying to block was actually making its way back through the BNC because of its proximity to the radiator. I now have it sealed and wire tied to the boom of my arrow and it works better than I ever expected the arrow diplexer could.

FWIW, I have operated my FT-817 reciever/FT-857 transmitter using the MFJ
duplexer (with the 70cm side unterminated ) as a 2m BPF successfully.

Once I tuned my arrow for a good 50ohm match, I have also used the same
setup with no duplexer at all - tested at up to 30w with no interference
between rigs on either mode J or B. I'm not necessarily recommending you do
it that way, just saying it's worth experimenting for yourself (as Mike
did) to find out what works best to solve a problem in your particular
situation.

Hi!

I will be part of the AMSAT presence at the ARRL Nevada State
Convention, also known as NVCON, this Friday through Sunday
(31 March - 2 April 2017) in Las Vegas. The convention will
be at the Eastside Cannery Casino-Hotel along Boulder Highway,
east of the Strip and southeast of downtown Las Vegas. More
about the convention is available at:

http://nvcon.org

Frank Kostelac N7ZEV, a long-time AMSAT Area Coordinator in
Las Vegas, and I will be around the AMSAT booth at the convention.

Weather permitting, I will have some demonstrations of satellite
operating from outside the hotel during the convention. If you
hear WD9EWK on the satellites from NVCON, please call and be a
part of the demonstrations! Last year's NVCON weekend was a wet
one, with a lot of rain that washed out any chances to do
demonstrations during the convention. This weekend is supposed
to be better, and drier. The convention site is in grid DM26.

Any QSOs made during the convention will be uploaded to Logbook
of the World. If you would like to receive a QSL card for a QSO
with WD9EWK during NVCON, please e-mail me directly with QSO
details. If you're in the log, I will send a card.

During the convention, I will tweet photos and updates on my
@WD9EWK Twitter account. These tweets are available for anyone to
see, even if you don't have a Twitter account, at:

Hi!

I am driving to Las Vegas for this weekend's NVCON convention,
and I already posted a message to the -BB about that event.
Before I reach Las Vegas on Friday (31 March), I am planning
on a stop in Kingman, Arizona, on the DM25/DM35 grid boundary.
I'm hoping to make it to Kingman around 1600 UTC to work some
passes, before driving the last 100 miles/160km from Kingman
to Las Vegas and the NVCON convention.

After the convention wraps up on Sunday (2 April), I plan on
heading back to Phoenix, but not directly to Phoenix. I can
make stops on one of 3 different grid boundaries:

1. DM25/DM35 grid boundary in Kingman AZ (a repeat of the
   stop I plan to make on Friday morning)
2. DM24/DM25 grid boundary, about 15 miles/25km south of
   Kingman along the I-40 freeway
3. DM26/DM36 grid boundary in northwestern Arizona, near
   the I-15 freeway and northeast of Mesquite NV

Any preferences on which grid boundary you'd like to hear me
operating from?

I don't know what time I will depart Las Vegas on Sunday, so
I can't post any schedules for operating from any of these
locations. As with my other road trips, I will use APRS as
WD9EWK-9 as I drive. You can see my APRS track at (among
other online places):

http://aprs.fi/WD9EWK-9

QSOs will be uploaded to Logbook of the World, and QSL cards
will be available on request (please e-mail me directly with
QSO details, if you want a card). Updates should also appear
on my @WD9EWK Twitter account, also visible at:

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at

Message-ID: <68f42a5b-2e85-b1b2-2466-086ccd19f786@rogers.com>

Hi All,

Following is my tentative schedule for this Friday.  I am making brief 
stops in EN97 and FN08 to hand those grids out to a few who didn't get 
them previously.  It takes 6+ hours to get there and then several more 
hours after that to get to my hotel.  If we don't connect on this 
stopover then let me know and we'll try to work something out for my 
return trip on Monday morning.

I'll be worn out when I arrive in Cochrane (EN99) Friday evening, so 
don't be too disappointed if I don't make all of the Friday night 
passes. Catch me early because I might turn in early.  I will be staying 
in Cochrane for three nights, so you can catch me on Saturday or Sunday 
night if you miss me on Friday.  EN98 is only a few minutes' drive 
away.  The aptly named 49th Parallel Road runs along the boundary so I 
might head down there for the evenings and hand out two grids!

Please get in touch with me if you see that my schedule hasn't given 
your area the coverage you were hoping for.  Let me know your AOS and 
the satellite and I'll see if I can do it from here.

The weather forecast still looks decent.  It should be a fun weekend!

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.  

For proposal information and more  details such as expectations, proposal 
guidelines and proposal form, and dates  and times of Information Sessions go 
to  http://www.arrl.org/hosting-an-ariss-contact.  
Please direct any  questions to  ariss at arrl.org.

Today's launch was good.

The first stage has successfully landed on the recovery barge, making
the first time that a refurbished SpaceX booster has been flown and
returned.  Unfortunately, the video feed of when it happened was lost.

Meanwhile, the second stage is well on its way.

Well done!

I worked for SES for 18 years.  My peers still working at SES were very
nervous.  But very happy now.  SES-20 is in transfer orbit.  They have two
more burns to do before getting into geostationary orbit.  $150M satellite
launches are exciting!

Hi!

I have updated my plan for the next 3 days, driving up to Las
Vegas for the NVCON convention and other non-convention radio
operating in southern Nevada and northwestern Arizona. The
plan is...

Friday, 31 March - from 1600 or 1730 UTC until 1930 UTC,
      working from DM25xg/DM35ag grid boundary, north of
      I-40 in Kingman AZ.

Friday night (1 April, UTC time) - from around 0230-0330
      UTC until at least 0530 UTC, working from DM26xt/DM36at
      grid boundary, east of I-15 freeway in NW Arizona and
      east of Mesquite NV.

Saturday and Sunday, 1-2 April - during the daytime,
      demonstrations from the NVCON convention in Las
      Vegas NV in grid DM26.

Sunday, 2 April - from sometime around 2000-2200 UTC
      into the evening, working from the DM24wx/DM25wa
      grid boundary, along the I-40 freeway frontage road,
      about 15 miles/25km south of Kingman AZ.

There may be a chance on Saturday evening (2 April, on the
UTC clock) or Sunday (2 April) morning from the DM25/DM26
grid boundary, south of the NVCON convention in the Las
Vegas area. I will try to post those plans here on the -BB,
and will definitely post that to my @WD9EWK Twitter feed:

http://twitter.com/WD9EWK

Although I try to update my log in Logbook of the World
quickly, please be patient. Some of the spots I will visit
may not have good coverage for my mobile phone, and I will
be looking to drive a lot in the next 72 hours or so.

I will hit the road Friday morning, and my TH-D72A will
squawk WD9EWK-9 on the APRS network:

http://aprs.fi/WD9EWK-9

APRS coverage for most of my drive to Las Vegas should be
decent. I'm not sure how well it will cover me tomorrow
night near the DM26/DM36 grid boundary, so looking at my
Twitter feed may be the best way to know when I reach these
spots.

73!

Message  to US Educators
Amateur Radio on the International Space Station 
Contact  Opportunity 

Call for Proposals 
Proposal Window February 15 ?  April 15, 2017 

The Amateur Radio on the International Space  Station (ARISS) Program is 
seeking formal and informal education institutions  and organizations, 
individually or working together, to host an Amateur Radio  contact with a crew 
member on board the ISS.  ARISS anticipates that the  contact would be held 
between January 1, 2018 and June 30, 2018. Crew scheduling  and ISS orbits will 
determine the exact contact dates. To maximize these radio  contact 
opportunities, ARISS is looking for organizations that will draw large  numbers of 
participants and integrate the contact into a well-developed  education 
plan. 

The deadline to submit a proposal is April 15,  2017.  Proposal information 
and documents can be found at  www.arrl.org/hosting-an-ariss-contact.

The Opportunity 
Crew  members aboard the International Space Station will participate in 
scheduled  Amateur Radio contacts. These radio contacts are approximately 10 
minutes in  length and allow students to interact with the astronauts through 
a  question-and-answer session. 

An ARISS contact is a voice-only  communication opportunity via Amateur 
Radio between astronauts and cosmonauts  aboard the space station and 
classrooms and communities. ARISS contacts afford  education audiences the 
opportunity to learn firsthand from astronauts what it  is like to live and work in 
space and to learn about space research conducted on  the ISS. Students also 
will have an opportunity to learn about satellite  communication, wireless 
technology, and radio science. Because of the nature of  human spaceflight and 
the complexity of scheduling activities aboard the ISS,  organizations must 
demonstrate flexibility to accommodate changes in dates and  times of the 
radio contact. 

Amateur Radio organizations around the  world, NASA, and space agencies in 
Russia, Canada, Japan and Europe sponsor this  educational opportunity by 
providing the equipment and operational support to  enable direct 
communication between crew on the ISS and students around the  world via Amateur Radio. 
In the US, the program is managed by AMSAT (Radio  Amateur Satellite 
Corporation) and ARRL (American Radio Relay League) in  partnership with NASA and 
CASIS (Center for the Advancement of Science in  Space).


More Information
Interested parties can find  more information about the program at 
www.ariss.org and  www.arrl.org/ARISS.

busy center on the FO-29 pass around 16:08 UTC today. So many QSO's
squeezed in the middle 20 kHz is a shame on a 100 kHz wide transponder.

Hi folks,

FUNcube/AO73 is now in full time amateur mode with the transponder ON. The
plan is for it to switch back to auto mode on Sunday  pm UTC as usual.

Please  see below for other FUNcube transponder info

Have FUN with the transponder.

73s Jim G3WGMand the FUNcube team.

++++++++++++++++++++++++++++++++++
FUNcube frequencies and other details
++++++++++++++++++++++++++++++++++

AO-73 FUNcube-1

The transponder is normally operational only when the satellite is in
eclipse, ie the solar panels are NOT being illuminated. During weekends
(from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.

When the transponder is switched off, the telemetry beacon is on full power,
when the transponder is on the beacon it is on low power. During holidays,
eg Christmas, New Year, Easter, etc, the transponder maybe activated for
extended periods. Watch AMSAT-BB for announcements which are usually made on
Friday evenings (UTC)

The nominal transponder frequencies are:

Uplink:   435.150 - 435.130 MHz LSB (Inverting)
Downlink:   145.950 - 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK

(The passband may be up to 15kHz higher depending on on-board temps. Lower
temperatures give higher freqs!)

FUNcube-2 (aka FUNcube on UKube)

The FUNcube-2 sub-system continues to operate autonomously and, almost
continuously, in amateur mode. The transponder is operational and the
telemetry downlink is functioning with about 70mW output. The FUNcube-1
Dashboard does not correctly display the telemetry but it does correctly
decode the data and uploads it to the FUNcube Data Warehouse from where it
can be examined. Most of the real time data channels are operational and
these include battery voltages, temperatures and ADCS data coming via the
main On Board Computer (OBC).

The transponder is interrupted for a few seconds every 2 minutes when the
other transmitter sends its CW beacon and, occasionally, for a few seconds
when the main OBC reboots (approx seven times each orbit).

The nominal transponder frequencies are:
Uplink:   435.080 - 435.060 MHz LSB (Inverting)
Downlink:   145.930 - 145.950 MHz USB
Telemetry Tx: 145.915 MHz BPSK

(The passband may be up to 10kHz higher depending on on-board temps. Low
temperatures give higher freqs!)


EO79 FUNcube-3
Due to power budget constraints the transponder cannot be operational 24/7
and an orbit specific schedule has been developed. The transponder will
commence operation 27 minutes after the spacecraft enters sunlight and will
stay on for a period of 25 minutes. This schedule may be modified in future
months as a result of experience.

The nominal transponder frequencies are:
Uplink: 435.0723-435.0473 MHz LSB (Inverting)
Downlink: 145.946-145.971 MHz USB

Further detailed info on EO79 transponder frequencies is at:
https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/


EO88/Nayif-1/FUNcube-5

EO88 is presently operating in autonomous mode. The transponder is
operational when the satellite is in eclipse, ie the solar panels are NOT
