I have recently resurrected, for Easter, an ancient Kenwood TS-9500, a 435 MHz Sat radio. While reading this topic, I suddenly realized that there was no CTCSS technology in this radio, but I could never tell while on air, on SO-50, AO-91, or AO-92, today! This is not meant to discourage people adding the tiny and affordable CTCSS generator to an older radio. This reflector is a great source of information to learn and accomplish this? .....it's all for fun?

Hi Cee, I'm afraid despite your observation, it DOES matter on SO-50... it will not retransmit your signal without the tone. (unless it's while you are overriding someone else's signal) Please DO NOT transmit to SO-50 without a CTCSS tone of 67.0 Hz as you can and likely will CAUSE QRM. There are a number of terrestrial stations now (cross band repeaters, remote bases, etc.) that transmit on the SO-50 2m uplink without a tone and cause considerable QRM problems. Their strong signals 'collide' with stations trying to talk through SO-50 and it results in at most a squealing crash of signals, but more than likely nothing getting repeated at all. (Sometimes the 'dead air' on SO-50 is because of either this or because too many ops are trying to transmit at once... no one clearly gets through and the tone is not heard by the receiver; SO, it doesn't key up the downlink.) Without the tone, we cannot hear these QRMing stations when they 'transmit in the clear' in order to catch a callsign or a location. Just to be clear... this is the case with SO-50... AO-85, AO-91 and AO-92 are different.

Their strong signals 'collide' with stations trying to talk through SO-50 and it results in at most a squealing crash of signals, but more than likely nothing getting repeated at all. (Sometimes the 'dead air' on SO-50 is because of either this or because too many ops are trying to transmit at once... no one clearly gets through and the tone is not heard by the receiver; SO, it doesn't key up the downlink.) Without the tone, we cannot hear these QRMing stations when they 'transmit in the clear' in order to catch a callsign or a location. Just to be clear... this is the case with SO-50... AO-85, AO-91 and AO-92 are different.

Is it just part of the 500mW transponder ? Or is there a separate dedicated amount as in AO-73 [Which is 300mW beacon mode, 30mW transponder mode] ? Essentially, I can decode NAYIF-1 Telemetry. I can also decode AO-73 telemetry when the beacon is in high power (300mW), but not when AO-73 is in Transponder mode, where the beacon is only 30mw (-10dB). Depending on the power output of NAYIF-1, I may be able to determine if I really need a 10dB improvement in order to receive AO-73 telemetry while in transponder mode, or if I am in fact, only need 3 or 6db improvement, which could change my strategy (This is a very small station in an urban environment running off a Raspberry Pi 3, with non steerable antennas, and I'm seeing it as an engineering experiment) 73s Iain PS, *grumble* They are too close together frequency wise.

If one simply looks at latitude as a number, then the latitude near the inclination will have a higher probability of appearing. But the best feedback came from Ralph W0RPK who pointed out this page which is tracking the orbit with updated predictions: http://www.aerospace.org/CORDSuploads/TiangongStoryboard.png And the USA is about as far as you can get from the predicted impact. The USA is 12 hours out of cycle with the orbit. The prediction there is currently showing about 0000 UTC which is 8 PM EDT plus or minus 2.5 hours. (which is about 3 orbits worth). And although those orbits cover a vast Pacific and Atlantic oceans, a good portion of them cross the middle east through Russia and china.

The in-orbit power levels, which are actually above the nominal quoted figure, can be read from the PA forward power telemetry in the Dashboard and in the Warehouse and the calibration of these channels is pretty accurate.? Of course, in amateur mode the output power level includes the transponder but if this not being used then this is probably only 5 mW or so.? The EO88 downlink is probably 1.5dB stronger in both modes. You can also look at the downlink of UKube-1 which is always in amateur mode. With a turnstile omni antenna I would expect to get perhaps 15/20 frames of telemetry on a good, near overhead,? pass from AO73 in amateur mode and at least 60-70 frames when in educational mode but as you mention the local noise level will affect these numbers greatly. Finally, if you are using the FUNcube dashboard on the Raspberry we would love to have some details of your implementation for publication the AMSAT-UK Oscar News magazine! 73GrahamG3VZV PS re your "grumble" - yes this was a lesson learnt for the design team!

I know it's divide by zero, but not sure why my satpc32 does not like it with AO-92 running. I have a 16 turn RHCP helix I want to try. Could use more than 24 hours per week.

In-Reply-To: References: Message-ID: <39c31af4-1bd8-6903-7723-896e28156b72@vfr.net> Hans, Here are links with antenna patterns for the DCA: https://drive.google.com/file/d/0B0Dkk87YYl-xX2gzLXk5MHZKVU0/view and the EZ-Lindenblad: http://www.amsat.org/wordpress/wp-content/uploads/2015/08/An-EZ-Lindenblad-Antenna-for-2-Meters2.pdf The difference is in the lengths of the "RG-59 (75ohm) phasing harness" and dipoles to achieve a 50 ohm impedance at the required frequency. The angle of the crossbooms affects the directivity of the antenna, in the examples given, 60 degrees for a NOAA satellite in a geosynchronous orbit and 30 degrees for a LEO orbit. The only differences I see are the 50 ohm load feedpoint and the Lindenblad dipoles are not exactly in the same plane as the DCA. -73, Joe Spier, K6WAO President, AMSAT On 04/01/2018 06:28 AM, Hans (BX2ABT) wrote: > Double Cross Antenna (DCA) From w5rkn at w5rkn.com Sun Apr 1 20:16:31 2018 From: w5rkn at w5rkn.com (Ronald G.

At 1296 MHz with 20w and a moderate sized yagi - you can work JT65 EME (moon bounce) with on of a super stations like HB9Q. If you can generate 1296 MHz SSB. Keep weak signal EME in mind. 73 - Paul - W2HRO On Sun, Apr 1, 2018, 15:27 Bob- W7LRD wrote: > Hello everyone > > -I finally got my 1.2ghz working!

I had a total of 43 QSOs on all four FM satellites over a span of 4 days.? I have uploaded my QSOs to LoTW and QRZ.com and will upload to eQSL this evening. There were a couple of call signs that I apparently did no get correct. I had them listed in my log as KA7FBP QSOed on 3/29 and KK6DDT and K7ULF both QSOs on 3/28. If this looks like your call, please let me know so that I can correct my log.

Many will be aware of the work carried out by " CHORDS " but perhaps many have never even heard of the organisation and its work. They are greatly involved with the work and tracking of "Space Debri" and the concerns. Tiangong -1 with co-ordination from a number of parties was fitted with an "REBR Probe" - It logged an sent various data from the spacecraft to enhance its locations for predictions. I understand that further work and developments of the probe have also been made recently so many may find this topic of interest.

Yes, the phasing harness is different, but my guess was that this shouldn't make a lot of difference as long as you get the 90 degree phase and the impedance right. If you look at the radiation patterns for both then they are nearly identical, hence my question if they are not one and the same thing. It came up here because I have two DCAs right now, one for 2m, one for 70cm, both RHCP, no pre-amps. I do hear some birds, but signals are very weak. The 2m one works fine when receiving the NOAA wx sats, so I was wondering if the 30 degree angle of the Lindenblad would be better for amateur sats. I lack the knowledge to understand the difference between, what you say, the geosynchronous orbit of NOAA sats and the LEO orbits of our sats. NOAA wx sats are also LEO sats, not? I'll see if Google turns up something there. It's easy for me to change the tilt of my DCAs to 30 degrees, so I'll try that this week.

(neither?) Message-ID: Neither are going to hear much on the horizon for typical weak amateur satellites where they spend most of their time. These antennas have gain that is at best 3 dBi It is very important to understand that all Low Earth Orbit sateliltes spend more than 70% of their in-view time below about 22 degrees. And satellites that low are 6 to 10dB farther away than when they are high up above 45 degreees. See the scale drawing of an orbit on the right side of this page: http://aprs.org/LEO-tracking.html The DCA and Lindenblad and Eggbeaters and all other such omni antennas are designed to give good performance over all elevation angles for sateliltes. But to do this, they are equally poor in all directions. This is wasteful since you need less gain at high elevations and much more gain at lower elevations for LEOS (98% of all amateur sateliltes?). So you have two choices. Use an omni and only get high passes (less than 30% of all time-in-view), and hear only strong satelites down on the horizon... Or, use a terrestrial style antenna with gain on the horizon... but by definition, these will have a null higher up, and for a typical mobile whip, that null might be at 15 or 20 degrees which is right where satellites spend their most time. Best option is to switch back and forth... but then if you are going to be sitting there, y ou may as well control a beam... (I still have not found such an ideal antenna (though lots of claims are made)... On the other hand, if I am going to simply want OMNI coverage for satellites above about 30 degree, then I prefer the simple 19.25" quarterwave whip over a big ground plane. Because this gives 5 dBi on 2 meters and about 7 dBi on UHF and is nothing more than a 19.25" piece of wire sticking up from a large ground plane. Much easier than all those other omnis that provide less gain everywhere. Though I have never done rigorous studies to prove its performance. But what could be simpler to test. If I had any of those complex omni's., I'd love to do such a comparison some day... after I retire...

Message-ID: <15112f59-4900-4148-bb5c-69e052f56b7a@gmail.com> Hi to all. This is half OT, sorry for that. As you may know Cuba has (now) a growing network infrastructure for the National Ham Radio Association with at least a node with ADSL in each province and a internet connected central link in Havana; I have managed to make strong links with the Senior System Administrator (I'm a sysadmin also) and we are willing to put more ham related services in the net mostly for local users that connect to it via dialup connections (almost 30% of the hams are registered) and why not for international users. We tested and setup a DXcluster (Linked DXSpider node) that was a big success among our users. We are now thinking on kind of internet connected APRS server that acts as a gate (kind of proxy) for the internal network and then a first node on my city (Camag?ey, 500 Km east of Havana, FL11BJ) to test a on-air APRS and link it to the internal APRS server and I was thinking on setting a VHF packet on 145.825 Mhz as a bi-directional Sat-gate. The main questions are this: (Any advice, critics, links, help is appreciated) * There are any real interest in a VHF APRS SAT GATE in my location (FL11BJ) ? or it will be more noise in the net... * Any lead in how to mount a internet only aprs server and how to link it to the global APRS internet network? * Any other suggestion on what network-ham-related project we can setup on the national network described on the first paragraph? * Any other list/reflector where this can be interesting... ? The OS by choice will be Linux (Debian 9 or Ubuntu LTS), we plan to use direwolf as software modem on linux, we are seeking for a rbpi to test as we have no real hardware right now but a trusty Yaesu FTL-2011 VHF radio, we are on the plan stage and seeking for advice.

Oh, and let me just say that you can search all you want on Google for this; everyone that answers seems to have JDK installed. In that case, you can just type 'java' to get the JVM and all is well.

So although there are some differences, we talking about total crap or only partially crap. Based on my own experiences with a couple of different omni antennas, as I recall a few years back when I was trying to pass decoded packets from the original PC-Sat (if I remember right), the best I could do was a couple of decoded packets per week. Between the weak signal and no automated dopler shift, it was pretty much wasted effort. One thing going against me is that I live in the very RF congested Los Angeles basin, so that may have been working against me. 73 ----- Jim Walls - K6CCC jim at k6ccc.org -----Original Message----- From: "Brad Brooks" Sent: Monday, April 2, 2018 09:33 To: amsat-bb at amsat.org Subject: Re: [amsat-bb] Lindenblad or DCA???

I use something like 20 for SSB/CW and 50-200 for FM/PKT. That sets how much freq. change must occur before a new value is sent to the rig. You could try using "Speed x5" but usually I don't find that necessary. Just have the VFOs updated more often. Might fix what you're seeing. You can actually set the Interval values as low as 0 :) It updates constantly....

You may already do this but: Is your computer clock right on? I have a simple program running that goes out often and checks my computer clock against a time standard and resets the computer clock to the correct time. Another important items is are you using relatively recent Keplerian elements? With some birds, week old keps can make a difference. I am a member of AMSAT and appreciate everything they do for us. However, sometimes the Keps on AMSAT are a week old. I download them from CelesTrack with Space Trak TLE Retriever, they may be hours old. Finally with the low, high drag orbit of the ISS you can be off by minutes when they boost it?s orbit once in awhile. 73, Rick WB3CSY Sent from Rick's iPad 3 "Every kid starts out as a natural-born scientist, and then we beat it out of them.

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary.

One other option would be to look at the SatNOGS project: https://satnogs.org This is an open-source project to create a network of satellite ground stations; it uses the Raspberry Pi as a reference platform. By default it uses RTL-SDR for a radio, but there's support for anything supported by Hamlib as well (https://github.com/Hamlib/Hamlib/wiki/Supported-Radios).

So I bought an Airspy Mini and it was plug-n-play (after installing the drivers in the Kubuntu repositories).

With the exception of the Icom 9100, when Icom makes a satellite rig, they only include satellite bands. Witness the 970, no modules for 6m or 222mhz and the 13cm module for it (which is rare to find) covered 2400 to 2450mhz, but didn't cover the 2300-2310mhz portion of the band which is where weak signal activity takes place, at least in the US. The 820 and 821 only covered 2m and 70cm, and the 910 covered 2m and 70cm with the only optional module being for 1.2ghz, another satellite band. 33cm is also a ham band in Somalia (Region 1) and in New Zealand (Region 3), so it is making inroads in other parts of the world. 1.25m is also a ham band in Somalia. 73 John AF5CC On Wed, Apr 4, 2018 at 11:01 AM, Zach Metzinger wrote: > On 12/23/16 20:51, Todd via AMSAT-BB wrote: > > Thinking about adding the 1.2Ghz module for my 9100.

On both platforms, I used gqrx as the SDR software and SoapySDR as the interface between gqrx and the SDRPlay drivers.? Note that on the Raspberry Pi 2 I had to keep the sampling rate down (400 ksps) and the waterfall size at about 2K samples in order to prevent stuttering.? Given that I'm going to use the RSP2 for satellite reception, this was not a great sacrifice.? A Raspberry Pi 3B or 3B+ would be a better choice. 73, Mac Cody / AE5PH On 04/03/2018 09:25 PM, Greg D wrote: > Hi folks, > > Anybody gotten the SDRPlay2 (RSP2) to be recognized under Linux?

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary. To sign up, go to https://ariss-proposal-webinar-spring-2018.eventbrite.com For more details such as expectations, proposal guidelines and the proposal form, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html ? ****************************************************************************** ARISS is always glad to receive listener reports for the above contacts.?

Previously I have used an FT-897 and FT-817 with an Arrow to get on the birds. I also used a Heil Traveler with this combination: the RJ-45 plugged into the FT-897, and the RCA plug in the FT-817. The FT-897 was always for transmitting, and the FT-817 was always for receiving. This has worked very well! Recently I wanted to carry lighter equipment. So, I obtained a second FT-817. The idea is for it to replace the FT-897. However! Despite my best efforts, I cannot make the Heil work. It will not key the transmitter of either FT-817 unless the headset speakers are also connected to the same FT-817. As well, one of my favorite features of the FT-897 was that it would send CW when in SSB mode using the up/down buttons on the Heil. This does not work with the FT-817. The stock Yaesu mic keys everything fine. It does not plug anything into the audio out jack. Any experts have an idea what I mean ssed?

Menu item 36 must be set to ON on the 817 TX rig AND the Keyer must be turned on... to do that, hit 'F', then spin the SEL knob to [VOX, BK, KYR] and make sure a black Arrow icon to the right of 'KYR' is there. If not, press the 'C' button to activate the Keyer. - If these are set correctly and the +/- buttons still do not activate the CW keyer... it sounds like a sign of a ground problem between the headset and the RJ-45 jack, which is what I think is going on with the lack of PTT when the speaker audio is not plugged in. (See below.) > It will not key the transmitter of either FT-817 unless the headset speakers are also connected to the same FT-817. My Heil Traveler Dual will key my 817 without the headset speaker audio plug connected. I would suspect a ground problem going to the RJ-45 mic plug. Check continuity of the ground line between the 8 pin round plug and the RJ-45 plug... there are TWO Grounds and they are SEPARATE in the Heil adapter cable! Mic Ground is for the mic only and Ground is for the switches. - You will likely need to find a piece of very small gauge wire to make contact with the RJ45 contacts as a typical VOM probe will not fit in those small grooves. Unless you have a spare, unconnected RJ-45 jack handy... even better! Heil Traveler Pinout: 1 Mic, 2 NC, 3 + Switch, 4 ? Switch, 5 PTT Switch, 6 Ground, 7 Mic GND, 8 Earphone -- The outer metal shell of the 8 pin plug is not connected to ground, and should not show a connection to any of the pins. The +, - and PTT switches will make connection between their respective pins and ground (pin 6) when closed. The pin numbers should be visible on the female side of the 8 pin connection, visually transpose those locations for the male side. For the 817 mic jack pinout, you can consult the 817 manual (page 5 in my 817ND manual). If you don't have one, the order is: Fast, GND, PTT, Mic, Mic GND, +5v, Up(+ switch), Down(- switch) However the direction that order goes depends on which way you are looking at the jack/plug... if I have the plug laying contacts up & clip down with the end facing me (cable running away) that would be the L-R order. If turned around, it would be R-L... you should be able to figure it out. =^) You might check them all, but you want to make sure that the Heil Pin 6 goes to the RJ45 ground and should also show continuity to the speaker plug ground. (Also check that Heil pin 7 goes to mic ground on the RJ45 and that pin ONLY... it should not have continuity with the other ground connections; while unplugged, of course.) If these are not all correct, you have likely found your problem... Because it sounds like to me, you get PTT return through the ground connection of the speaker audio plug. When you disconnect that and there is no connection between Pin 6 and the appropriate RJ45 contact, no ground for either the PTT OR for the up/down buttons! (as referenced above) If the above still doesn't locate the 'lack of PTT' then the next step would be to check the mic jack contacts in the radios. But if you DO determine that the cable is missing a proper Pin 6 ground, then it means a new adapter, a new RJ45 plug, or in a pinch, you might just ground the two radios together. (not the best practice, but it'll do in a pinch) - Which this all gets me thinking... quick short cuts... do you have another Heil Traveler adapter for RJ45 yaesu? try swapping them. Also, might plug up just the RJ45 part of the adapter and check pin 6 to radio case ground (BNC jack shield on front). If that's good, it's something else. If you need any more help or clarification, include my offlist e-mail address to be sure and get my attention quicker. 73, Kevin N4UFO From jean.marc.momple at gmail.com Fri Apr 6 15:55:13 2018 From: jean.marc.momple at gmail.com (Jean Marc Momple) Date: Fri, 6 Apr 2018 19:55:13 +0400 Subject: [amsat-bb] AO73/FUNcube-1 mode change In-Reply-To: References: Message-ID: <89A7E312-30D4-4212-BEA1-4BFA578D83C1@gmail.com> Graham, Confirm it is and working fine, just heard myself very well through the bird in the middle of Indian Ocean.

This can be the seed for all hams to have such an AP so that when they witness something and are beyond cell service, they can snap a pix, and send if via their HT o r mobile, and similarly receive such remote area images too over Ham radio. The technology is here. Kenwood did the VCH1 Handheld SSTV system back in the 90's but it was hardware specific and before its time. Now, EVERYONE has the SSTV processing power in their pocket to make ham radio imaging possible anytime anywhere. Let's start practicing our ability to use it.

Doors open at 6:30 PM for a cash bar with the buffet dinner served at 7:00 PM. Jeri Ellsworth, AI6TK, will present on her innovative ideas and adventures in Amateur Radio. Jeri is an American entrepreneur, self-taught engineer, and an autodidact computer chip designer and inventor. She gained notoriety in 2004 for creating a complete Commodore 64 system on a chip housed within a joystick, called C64 Direct-to-TV. That "computer in a joystick" could run 30 video games from the early 1980's, and at peak, sold over 70,000 units in a single day via the QVC shopping channel. Ellsworth co-founded CastAR (formerly Technical Illusions) in 2013 and stayed with the company until its closure on June 26, 2017. In 2016, she passed all three amateur radio exams, earned her Amateur Extra license, and received the AI6TK callsign. This has now launched new adventures into Amateur Radio. She has been featured in January 2017 QST and in YouTube videos from Quartzfest earlier this year. Jeri has been given a free hand to speak on whatever topic she wishes (as long as it's amateur radio, somewhat).

The first launch at 9:05am was BLT-49.2 and was a 300g 'popper' latex balloon carrying a digital Fireball smart beacon sending the temperature in CW on 14.318 MHz & 28.322 MHz. We copied the weak CW beacon until 11:45am and believe it burst at well over 110,000 feet based on the time aloft and temperatures we were receiving. Very successful flight! The second launch of BLT-49.1 occurred about 9:06am and was a 'floater' balloon (1m Qualatex Mylar) carrying a PecanPico 5 APRS tracker. It rose very slowly into the sky, escorted by several drones videoing the event, headed north then shot off to the east passing over Houston, Beaumont and New Orleans. After avoiding a few thunderstorms along the way, it is currently just below Panama City, FL at ~30,000 feet heading for Orlando & KSC! It can be tracked on aprs.fi or tracker.habhub.org (see links below). After crossing Florida, we're hoping to hear from it again on the other side of the Atlantic https://aprs.fi/#!mt=roadmap&z=11&call=a%2FAB5SS-11 https://tracker.habhub.org/#!mt=roadmap&mz=6&qm=1_day&mc=29.97358,- 84.9113&f =AB5SS-11 [ANS thanks John, AB5SS for the above information] --------------------------------------------------------------------- Upcoming ARISS contact with Pinson Valley HS, Pinson, AL An International Space Station school contact has been planned with participants at Pinson Valley HS, Pinson, AL on Apr. 10.

Doug Tabor, N6UA and Ken Alexander, VE3HLS will be teaming up to travel north to the James Bay area of Quebec to activate as many FO grids as are accessible by road, in the time we have. Our plan is to leave Toronto on May 5th, entering FO the next day, and spending 7 to 8 days activating rare grids. This area is extremely remote. The James Bay Road is the main corridor through the area and was built by Quebec Hydro to support construction of a province-wide network of hydroelectric projects. It's 610 km long. There are gas stations at each end and another somewhere in the middle. Likewise, the Route du Nord is a 406 km gravel road with no services. There is no cellphone service once you leave Matagami, QC, the southern terminus of the James Bay Road. We will only have internet access when we get to a town. The road will take us through, and give us access to FO01/02/03/10/11/12/13/20/21/22/23. With so many satellites currently available, having two operators will insure that everyone will have a chance to work one of us. If two satellites are in view at the same time, we'll be on both of them! We will also allocate ourselves so as to be present on as many FM satellites as are available to us.

Our USSTRATCOM ODR (Orbital Data Request) to distribute the AMSAT-NA TLEs was approved on March 27, 2018." Thanks to JSpOC, Perry Klein, W3PK and Paul Williamson, KB5MU for their help in this process. We are "good to go" for another year. On another note, sadly, the PICSAT team has announced today that PICSAT is no longer operational. But, Ray will continue to carry PICSAT TLEs for now.(Remember AO-07?)

April 2, 2018 Officials from CQ magazine and ARRL, The national association for Amateur Radio?, are excited to announce the launch of support for CQ magazine?s Worked All Zones (WAZ) award program on ARRL?s Logbook of the World (LoTW) system, effective Monday, April 2, at 10:00 a.m. EDT (14:00 UTC). The goal of the project was to create the proper technical support system to enable amateur radio operators to submit LoTW confirmations for WAZ credit and that has been accomplished, say CQ and ARRL officials. ?We are very pleased that participants in CQ's WAZ award program will now be able to use their LoTW confirmations for award credit,? said CQ Editor Rich Moseson, W2VU. ?CQ WPX Award participants have found it very helpful and we are sure it will be equally helpful for those pursuing WAZ and its many variations.? ARRL First Vice President Greg Widin, K0GW, concurred. ?Users of LoTW have been telling us for some time that they would like to use QSLs from LoTW to apply for the WAZ award. They will now be able to select confirmations to be used for WAZ credit.? Beta testing for bringing CQ magazine's WAZ award program into ARRL?s LoTW system had been underway since mid-December. Any problems in the implementation discovered by testers were corrected by the technical support team. Also, the documentation has been improved by feedback from the testers. At the same time, each LoTW user was given an additional WAZ account. Standard LoTW credit fees and separate CQ award fees will apply. Logbook of the World is ARRL's electronic confirmation system for amateur radio contacts. It provides a confirmation when both stations in a contact submit their logs to the system and a match between the logs is confirmed. LoTW has supported the CQ WPX Award program since 2012. CQ Communications, Inc. is publisher of CQ Amateur Radio magazine and is the world's largest independent publisher of amateur radio magazines, books and videos. Worked All Zones is the second-oldest active award program in amateur radio, behind only the International Amateur Radio Union's Worked All Continents award. ARRL The national association for Amateur Radio?, represents the interests of Amateur (or ?ham?) Radio operators across the country. Founded in 1914 by Hiram Percy Maxim as The American Radio Relay League, ARRL has a proud history of achievement as the standard- bearer in amateur affairs. Now in its second century, the organization remains focused on ?advancing the art, science, and enjoyment of Amateur Radio.?

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary. To sign up, go to https://ariss-proposal-webinar-spring-2018.eventbrite.com For more details such as expectations, proposal guidelines and the proposal form, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html ? ****************************************************************************** ARISS is always glad to receive listener reports for the above contacts.?

The event is scheduled to begin at approximately 18:02 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and KN4BBD. The contact should be audible over the state of Alabama 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. Pinson Valley High School is located in Central Alabama near the city of Birmingham and is one of 57 schools in the Jefferson County School system. We are a very diverse school with approximately 1100 students in grades 9-12. At PVHS students have many options for academic programs and extracurricular involvement. We have opportunities for students to take Advanced Placement or Dual Enrollment classes, a growing career technical education academy, and a very popular fine arts academy. We hope that our participation in the ARISS contact will build an increased interest in STEAM (Science, Technology, Engineering, Arts, and Mathematics) course pathways. There are many sport teams for both male and female athletes. On December 8, 2017 our football team won the Alabama 6A State Championship, a first for our school. Our motto is "At Pinson Valley High School we promote achievement, respect, and success." Go Indians! Participants will ask as many of the following questions as time allows: 1. By having zero gravity, what type of exercises you have to do to keep your body from losing mass? 2. What prompted your interest or love of space? 3. Psychologically, what is the most challenging aspect of being in space? 4. What type of research are you currently conducting on the ISS? 5. When you receive food supplies in space can you make special request for certain foods? 6. What can a high school student do now to prepare for a potential career in aerospace? 7. How much education and training does an astronaut typically have? 8. Theoretically could NASA power future rockets/spaceships via nuclear fusion, similar to the sun? 9.

This can be the seed for all hams to have such an AP so that when they witness something and are beyond cell service, they can snap a pix, and send if via their HT o r mobile, and similarly receive such remote area images too over Ham radio. The technology is here. Kenwood did the VCH1 Handheld SSTV system back in the 90's but it was hardware specific and before its time. Now, EVERYONE has the SSTV processing power in their pocket to make ham radio imaging possible anytime anywhere. Let's start practicing our ability to use it.

Doors open at 6:30 PM for a cash bar with the buffet dinner served at 7:00 PM. Jeri Ellsworth, AI6TK, will present on her innovative ideas and adventures in Amateur Radio. Jeri is an American entrepreneur, self-taught engineer, and an autodidact computer chip designer and inventor. She gained notoriety in 2004 for creating a complete Commodore 64 system on a chip housed within a joystick, called C64 Direct-to-TV. That "computer in a joystick" could run 30 video games from the early 1980's, and at peak, sold over 70,000 units in a single day via the QVC shopping channel. Ellsworth co-founded CastAR (formerly Technical Illusions) in 2013 and stayed with the company until its closure on June 26, 2017. In 2016, she passed all three amateur radio exams, earned her Amateur Extra license, and received the AI6TK callsign. This has now launched new adventures into Amateur Radio. She has been featured in January 2017 QST and in YouTube videos from Quartzfest earlier this year. Jeri has been given a free hand to speak on whatever topic she wishes (as long as it's amateur radio, somewhat).

The first launch at 9:05am was BLT-49.2 and was a 300g 'popper' latex balloon carrying a digital Fireball smart beacon sending the temperature in CW on 14.318 MHz & 28.322 MHz. We copied the weak CW beacon until 11:45am and believe it burst at well over 110,000 feet based on the time aloft and temperatures we were receiving. Very successful flight! The second launch of BLT-49.1 occurred about 9:06am and was a 'floater' balloon (1m Qualatex Mylar) carrying a PecanPico 5 APRS tracker. It rose very slowly into the sky, escorted by several drones videoing the event, headed north then shot off to the east passing over Houston, Beaumont and New Orleans. After avoiding a few thunderstorms along the way, it is currently just below Panama City, FL at ~30,000 feet heading for Orlando & KSC! It can be tracked on aprs.fi or tracker.habhub.org (see links below). After crossing Florida, we're hoping to hear from it again on the other side of the Atlantic https://aprs.fi/#!mt=roadmap&z=11&call=a%2FAB5SS-11 https://tracker.habhub.org/#!mt=roadmap&mz=6&qm=1_day&mc=29.97358,- 84.9113&f =AB5SS-11 [ANS thanks John, AB5SS for the above information] --------------------------------------------------------------------- Upcoming ARISS contact with Pinson Valley HS, Pinson, AL An International Space Station school contact has been planned with participants at Pinson Valley HS, Pinson, AL on Apr. 10.

Doug Tabor, N6UA and Ken Alexander, VE3HLS will be teaming up to travel north to the James Bay area of Quebec to activate as many FO grids as are accessible by road, in the time we have. Our plan is to leave Toronto on May 5th, entering FO the next day, and spending 7 to 8 days activating rare grids. This area is extremely remote. The James Bay Road is the main corridor through the area and was built by Quebec Hydro to support construction of a province-wide network of hydroelectric projects. It's 610 km long. There are gas stations at each end and another somewhere in the middle. Likewise, the Route du Nord is a 406 km gravel road with no services. There is no cellphone service once you leave Matagami, QC, the southern terminus of the James Bay Road. We will only have internet access when we get to a town. The road will take us through, and give us access to FO01/02/03/10/11/12/13/20/21/22/23. With so many satellites currently available, having two operators will insure that everyone will have a chance to work one of us. If two satellites are in view at the same time, we'll be on both of them! We will also allocate ourselves so as to be present on as many FM satellites as are available to us. Our plans aren't complete yet. We may activate other grids, or be forced to rein in our expectations depending on available time and the conditions we encounter. We will provide updates in the coming weeks.

April 2, 2018 Officials from CQ magazine and ARRL, The national association for Amateur Radio?, are excited to announce the launch of support for CQ magazine?s Worked All Zones (WAZ) award program on ARRL?s Logbook of the World (LoTW) system, effective Monday, April 2, at 10:00 a.m. EDT (14:00 UTC). The goal of the project was to create the proper technical support system to enable amateur radio operators to submit LoTW confirmations for WAZ credit and that has been accomplished, say CQ and ARRL officials. ?We are very pleased that participants in CQ's WAZ award program will now be able to use their LoTW confirmations for award credit,? said CQ Editor Rich Moseson, W2VU. ?CQ WPX Award participants have found it very helpful and we are sure it will be equally helpful for those pursuing WAZ and its many variations.? ARRL First Vice President Greg Widin, K0GW, concurred. ?Users of LoTW have been telling us for some time that they would like to use QSLs from LoTW to apply for the WAZ award. They will now be able to select confirmations to be used for WAZ credit.? Beta testing for bringing CQ magazine's WAZ award program into ARRL?s LoTW system had been underway since mid-December. Any problems in the implementation discovered by testers were corrected by the technical support team. Also, the documentation has been improved by feedback from the testers. At the same time, each LoTW user was given an additional WAZ account. Standard LoTW credit fees and separate CQ award fees will apply. Logbook of the World is ARRL's electronic confirmation system for amateur radio contacts. It provides a confirmation when both stations in a contact submit their logs to the system and a match between the logs is confirmed. LoTW has supported the CQ WPX Award program since 2012. CQ Communications, Inc. is publisher of CQ Amateur Radio magazine and is the world's largest independent publisher of amateur radio magazines, books and videos. Worked All Zones is the second-oldest active award program in amateur radio, behind only the International Amateur Radio Union's Worked All Continents award. ARRL The national association for Amateur Radio?, represents the interests of Amateur (or ?ham?) Radio operators across the country. Founded in 1914 by Hiram Percy Maxim as The American Radio Relay League, ARRL has a proud history of achievement as the standard- bearer in amateur affairs. Now in its second century, the organization remains focused on ?advancing the art, science, and enjoyment of Amateur Radio.?

This can be the seed for all hams to have such an AP so that when they witness something and are beyond cell service, they can snap a pix, and send if via their HT o r mobile, and similarly receive such remote area images too over Ham radio. The technology is here.? Kenwood did the VCH1 Handheld SSTV system back in the 90's but it was hardware specific and before its time.? Now, EVERYONE has the SSTV processing power in their pocket to make ham radio imaging possible anytime anywhere.? Let's start practicing our ability to use it.

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary. To sign up, go to https://ariss-proposal-webinar-spring-2018.eventbrite.com For more details such as expectations, proposal guidelines and the proposal form, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html ? ****************************************************************************** ARISS is always glad to receive listener reports for the above contacts.?

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary.

On Saturday, 14 April 2018, I will drive out to the DM54/DM55 grid boundary in eastern Arizona for the afternoon (more or less). I plan to leave Phoenix in the morning, and the drive out there should take about 3.5 hours. I do not plan on working passes in the morning on my way out to DM54/DM55, trying to make the drive so I can spend more time out there before driving home at or just after sunset. This is a day-trip, and I will not be able to make drives to other nearby grids or over to the New Mexico state line. The spot I will use for the DM54/DM55 grid boundary is east of I-40 exit 303, along the frontage road on the south side of I-40 in Navajo County - a spot I have visited a few times in the past several years. I plan on working FM, SSB, and FalconSat-3 passes. Maybe NO-84, if passes line up with the afternoon and the 145.825 MHz digipeater is operational. If AO-92 goes into L/V mode Saturday evening, I will try to stop and work passes from somewhere in northern or central Arizona during my drive home. During my drive, I will have a radio squawking to the APRS network as WD9EWK-9. You should be able to follow my travels at: http://aprs.fi/WD9EWK-9 Updates on Saturday will be posted to my @WD9EWK Twitter account. If you do not use Twitter, you can still view my tweets by visiting: http://twitter.com/WD9EWK My DM54/DM55 QSOs will be uploaded to Logbook of the World in the couple of days after I return home. 73!

Since EVERY ham with a smartphone, iphone, android or tablet (or old VCH1 KenCam) can send and receive SSTV images over the air via any HT or walkie talkie, NOW we have a real untapped emergency response imaging capability that we are not exercising. See http://aprs.org/aprn.html The APRN network allows anyone to upload or download any real-time image to/from the local APRN server via audio on a local VHF frequency. And they use their APRS handheld to send a message TO APRN that identifies the SENDER, TIME/DATE, and location of the image. This allows the image to be cataloged, sorted and saved and served on demand. The image is not only available over the air back to any radio user on demand, but is also available to anyone on the web, such as emergency operators to view images from the "scene". Sure, any smartphone can send an image via broadband. But with APRN, they can do it anytime, anywhere even without their wireless network and it is seamlessly shared locally and globally. And if we practice, anyone with an APRS radio can do it. AND the local APRN frequency is visible locally on the APRS map via its own FREQUENCY OBJECT. The only problem, is that I am too old to write the APRN code. The local APRN code runs on a local computer, and has two radios. One sending and receiving the SSTV images on the local APRN VHF channel, and the other radio is on the APRS channel for communicating the information and putting the images on the map and for receiveing image queries.

Consider the following: As I understand it, the goal is to adjust your transmitter such that your frequency at the satellite is constant. Our tracking program gives us range to the satellite and its velocity relative to us given our location and the orbital parameters. From this we should have computed Doppler for both transmit and receive. We also know the frequency at the satellite of the various beacons onboard. From this we can measure the doppler and work the other direction If we transmit a subaudable tone of known frequency we should be able to adjust the rx automatically by tracking the tone. (Acssb) Given these multiple ways of setting our tx/rx frequencies for our location can this not simply be automated to such a degree as to simply specify an offset from the beacon and operate as if it were a regular predictable opening on hf?

You must adjust the higher of the two frequencies as it is most affected by Doppler. The true way to adjust is really to adjust both frequencies, however in the absence of computer control of both frequencies, you adjust the higher.

The pass has a max elevation of 66 degrees so it should be a good opportunity to show some kids and their parents (and maybe adults without kids too!) ham radio satellites. I may have developed a high SWR issue with my mobile radio powered sat rig and the Arrow I use with it, so I may be forced to use "just" my 5 watt HT, so if you hear me having trouble getting through, please help out by letting me make a contact or two - it's for the children, come on. ;-) I'm also going to try and demo ISS SSTV on an earlier pass but it's only 5 degrees max elevation and I'm uncertain about the obstructions where we'll be. If it works they may get an even bigger kick out of that. I announced it on the Facebook event page and told people what apps they can download to decode it by holding their phones up to the speaker I'll have. 73, John Brier KG4AKV P.S. I am aware Patrick, WD9EWK will be roving to DM54/DM55 tomorrow but I imagine he'll still be driving there. Also, if I'm reading Orbitron right by moving my mouse pointer to DM54/DM55 it looks like this pass will only barely cover that area, if at all. Regardless, if he's on I will make sure not to keep anyone who needs the grid[s] from getting it[them].

We have no control over the satellite frequency, so the ground station must adjust... that seems obvious, but maybe I missed something or maybe you're talking about satellites which are not on fixed frequency transponders ? In any case, when the satellite is rising (or approaching), then the waves coming from it will be compressed, so RX frequency at the ground station will be higher than when it left the satellite. Since the satellite is approaching the waves hitting it from the ground station will also be compressed. So, both RX and TX will be higher in frequency. The opposite happens when the satellite is descending (or moving away from the ground station) i.e. waves from the ground station TX stretch in chasing the satellite and waves coming into the ground station are stretched as the satellite moves away, so both TX and RX will be lower frequency. Thus the ground station should tune up the band before the satellite appears (AOS) and should reduce frequency (both RX and TX) as the satellite rises, passes and sets. It will be above frequency at the start, on frequency right overhead and lower frequency from just past overhead to LOS. Or did I miss the plot ? 73, Stephen VE6SVJ SKCC # 14855 Okotoks, AB On 13 April 2018 at 20:49, Andy wrote: > So VERY true! > Thanks Bruce, > ANDY w5acm > > > -----Original Message----- > From: AMSAT-BB [mailto:amsat-bb-bounces at amsat.org] On Behalf Of Bruce > Sent: Friday, April 13, 2018 9:40 PM > To: amsat-bb at amsat.org > Subject: Re: [amsat-bb] Making the transponder sats as easy as the fm birds > > Sorry, this theory of thought is incorrect.

For FM, where we are familiar with the technique, that's fine. But instead of a tone, you'd perhaps be better off running Single Sideband AM (i.e. a sub audible tone of zero hertz); there was a satellite recently that was in that sort of mode (I forget which bird), and it was really interesting to work. BUT, one huge problem with sending up a "beacon tone" for aligning stations to, is that you're sending a 100% duty cycle carrier (though perhaps reduced power) to a transponder that really hates having 100% carriers run through it. That's one of the big reasons why they don't allow FM on the SSB / CW birds (the other being the extra bandwidth that it takes). Bottom line is that, yes, one can construct methods to aid in frequency tracking. But One True Rule software-assisted operation works really well already, for those who can use it, and can be backed all the way down to manual for those who can't. And, manual operation of an SSB station through a satellite is quite an interesting exercise. I often find it more satisfying than having to deal with starting up and fussing with all the computer automation "help". Just takes a bit of practice.

And it has effectively done it without sending garbage signals. There is also FlexTune which sends a tone to initially calibrate, then the rest of the Doppler corrections are done mathematically vs continuously sending garbage. Another thing of note, you're already sending your voice, why add more? The other software is initially calibrated manually then continues track with that offset automatically. Seems better than loading a transponder with even more nonsense. Personally, I don't see why people consider the linear transponders to me so mystical. They're simple: signal goes in one point, out the other. Big whoop. To tune just use a little bit of basic math skills that a 2nd grader should possess and then turn the knobs till the voices sound right. Pretty easy, right? Instead we have people who I've never heard on any satellite (in my two years and 10,000 sat QSOs) suggesting complex and unnecessary things to make operating on these satellites "easier", when most competent ops already find them plenty easy. 73, Gabe AL6D/actuallyoperateslinearsats On Fri, Apr 13, 2018 at 7:53 PM, Eric Fort < eric.fort.listmail at fortconsulting.org> wrote: > Computer control or actually a variation of such *IS* what I?m considering > and proposing.

Experience with the Mode J transponder on FO-12 caused the gudiance to be updated to tuning the higher of the two frequencies. See the Sept 14, 1987 Amateur Satellite Report for more details ( http://www.ka9q.net/asr-1987.pdf). With computer control, it?s a simple matter to adjust both your transmit and receive frequencies once you get your software calibrated, but for those tuning manually, the guidance is to tune the higher of the two frequencies and leave the lower frequency as constant as possible. Operating linear transponders takes a bit of practice, but it?s fairly easy and becomes second nature after you get a dozen passes or so under your belt. There?s no need to think up new schemes to make them ?easier.? 73, Paul, N8HM On Sat, Apr 14, 2018 at 08:19 Bill Booth wrote: > On 2018-04-13 9:41 PM, Eric Fort wrote: > > As I understand it, the goal is to adjust your transmitter such that > your frequency at the satellite is constant. > > I have been on the sats since Oscar 6 and the RS series and it was the > other way > around I thought.

What would be very helpful for complete beginners, like me. We need a knowledgeable unbiased review of all full duplex tx/rx's . With locked vfo's to maintain a fixed split to save operators moving around within bandwidth of transponders, when used manually. Also really helpful would be a review of all cat/ doppler tracking software when associated with these radios. To my knowledge, not that many models from mainstream manufacturers, have this facility.

As Paul said, the original "one true rule" of adjusting only Rx changed to adjusting the highest frequency frequency, but now (see Gould Smith's book, Appendix A) adjusting both is common if you have computer aided tuning. Both MacDoppler and SatPC32 can adjust both in this way (although MacDoppler can certainly be set to only change one frequency). I don't think that is in opposition to any rule. It is just an update of "The One True Rule". > > I've always been curious about that. > > Still using InstantTrack here. :-) > > KB7ADL > > > _______________________________________________ > Sent via AMSAT-BB at amsat.org.

The design of this spacecraft has been carried out as part of their curricula to acquire experience on the field. Students are involved on all the mission phases and they will also participate in operations. The second goal of this mission is technology demonstration, being this spacecraft one of the smallest ever launched belonging to the PocketQube class with a size of 50x50x192 mm. It contains all the required systems to operate in space. It is one of the first PocketQubes to be launched and it is the cornerstone for a series of PocketQubes from TU Delft with the aim to iteratively advance the platform to enable ambitious scientific objectives with networks of PocketQubes in the future. Delfi-PQ mainly focusses to demonstrate a reliable core system (comprising a power system, a communication system, an attitude control system and an on-board computer). Furthermore, it will host a few small-scale experiments which can be used for technology research. These experiments are related to future propulsion, more advanced attitude control, navigation, thermal analysis and control. The orbital life time of Delfi-PQ is currently foreseen to be very short (only up to 150 days due to the low orbit of deployment). This will ensure the spacecraft cannot contribute to the space debris problem and also it will occupy its assigned frequency band for a very short time, preventing spectrum pollution. The demonstration of the core spacecraft and its experiments is expected to take all the mission time, till deployment. The communi- cation system, in particular, will be tested and the support of amateurs will also be important. AX.25 will be used worldwide to deliver telemetry. The protocol was selected due to the widespread community around the world that make already use of such a standard. A mode using advanced communication protocol, using forward error correction, will be tested upon command (and so receivable over Europe). This new protocol is decoded by the provided decoding software. The decoding software will enable radio amateurs to help estimating the performance of the receiver in different conditions with statistics transmitted back to a central server In order to provide a return favor to the radio amateur community for the use of the frequency bands, this mission will publish all the instructions for satellite reception and telemetry decoding. A decoding application will also be provided to radio-amateurs around the world before launch to allow easy decoding with standard hardware. This application will also be used to submit the received frames to a central repository. The contribution from radio amateurs in receiving the data will greatly enhance the mission. To make it more exciting to participating radio amateurs, several challenges will be organized. Examples of challenges are thereception of the first and the last frame. In particular, the first received frame will be important for the team to assess the status of health of the spacecraft. The submitter will receive a prize for it. Since the satellite will be deployed to only 350 km and the foreseen operational lifetime is equal to the orbital life time, it will be very interesting to monitor its deorbiting process. Next to this, the number of received frames and the global distribution will also lead to the definition of several challenges. All challenges will have some small prize and achievement certificate associated with it. A UHF downlink on 436.650 MHz has been coordinated by the IARU. The transmission protocol will be GMSK at up to 19k2 bps. Planned for a launch on a Vector rocket from Kodiak Alaska in August 2018 with other PocketQubes.

The event is scheduled to begin at approximately 16:44 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and K5LBJ. The contact should be audible over the state of Texas 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. Students at Salado Intermediate School are third through sixth graders. The campus emphasis is to instill in our students a passion for learning, critical thinking, inquiry and collaboration. The unique experience of this ARISS contact aligns with that goal by making a lasting impression on the students, creating an interest in STEM careers for many of them. This radio contact allows our students to make a personal connection to the importance of space exploration and its developing technology. Participants will ask as many of the following questions as time allows: 1. How do you all get along in space, even though there are people from all different places around the world? 2. How does it feel to see the Earth from space? 3. Does being in space become normal to you, like going to school is for me? 4. What is one of the biggest challenges you have faced on the ISS? 5. If you could bring one more thing on board the space station what would it be? 6. Is it harder to breathe on board the space station? 7. What was the transition from the military to astronaut like? 8. If you could take a non-related person with you to the space station, who would you take and why? 9. What are you looking for when you are monitoring the Earth?s water from space? 10. What do you think the world would be like without space exploration? 11. How do you clean the space station? 12. What is the most interesting experiment you have done on the ISS? 13. How do you celebrate holidays on the ISS? 14. What are your first thoughts as you begin a spacewalk? 15. If you got to add another section to the ISS what would be in it? 16. If you could pick any food to eat right now, what would it be? 17. Why are bacteria stronger in space, or is the immune system weaker? 18. What is the hardest thing to get used to on the space station? 19. What would you change about the space suit and why? 20.

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.

They are now being sold by sdr-kits I think, and involve about ten solder joints being made at the most. The result, for me certainly, wqs that I have a dedicated "SDR Port" on the back of my rig, presented as an SMA, and a short bridge lead from the rig to the Funcube Pro+.

The one downside is having to manually unscrew coax connectors to swap the antennas from receiver to transmitter and vice versa when going from V/U to U/V and U/V to V/U. I don't want to use multiple antenna switches because if I or a guest op doesn't set them properly I could blow the front end of the receiver.

Not sure you?d need full carrier though. The advantage of a zero hertz tone is not having to notch it on rx, a ctcss tone is probably easier to generate on modern transceivers though. Having a (reduced) ?carrier? to measure and track would seem to be an aid to automated tuning of the receiver though. Sound card listens for the tone and adjusts rx frequency according to the offset from a known and agreed upon transmit tone. What I?m hearing here in the comments though and I?ll ask if this is correct.... is that the computational approach of adjustment based upon published elements is good enough. Can and does the computer frequency control get us close enough for hands off operating when both stations us it? Also if computer control and tracking is ?good enough? why is it not almost universal on the transponder sats? For the cost of a Raspberry pi or similar sbc and the proper ci-v / cat cable you have computer control of frequency. As cheap as this is compared to the cost of an all mode radio why is it not more often put to use? If computer control is not good enough for hands free operation, how can we make it so?

I understand this manual tweaking is how it?s currently done. Why however are we adjusting only one frequency? It seems that we can adjust the transmit frequency so that it is always the same distance from the beacon as seen by the satellite and the receiver can automatically track the subduable tone transmitted. This means that you need not drift across the transponder and the rx station automatically tracks.

You must adjust the higher of the two frequencies as it is most affected by Doppler. The true way to adjust is really to adjust both frequencies, however in the absence of computer control of both frequencies, you adjust the higher. Thus, if it is the receive frequency, then you adjust the receive, if it is the transmit, then you adjust the transmit. Holding the transmit frequency on the wrong band will cause you to walk across all the other QSO's taking place which is not a good practice. >>> >>> 73...bruce >>> >>>> On 4/13/2018 8:41 PM, Eric Fort wrote: >>>> I?ve had an idea for a long time as to making the satellites with linear transponders as easy to use as the FM ?easy sats ?.

My opinion is that computer control is plenty good enough. Even full manual control is good enough in the hands of an experienced operator. Neither method is going to be as easy as chatting on simplex or the local repeater "out of the box";, nor do I think they need to be. Both require some knowledge, learning (which is different than book knowledge), and practice. That learning is a big part of what the hobby is all about. Then it will be easy. It took me weeks of work and elmering to make my first satellite contact, and a lot of that success was due to the skill of the operator on the other end (Mel, KW7E). That was on RS-10, which was considered the ultimate "Easy Sat". The second contact took a lot less time, and pretty soon I could fire up the rigs, find myself, and be in business in seconds, all on a lash-up of equipment that I can only smile at today. There is certainly a place for automation. Those repeater contacts we have all made are aided by the rig's automatic offset shift on transmit. That makes sense, as it ties in with the band plan, repeater construction standards, physics of narrow bandwidth filtering, etc. We have no such structure on the transponder satellites, nor for a linear transponder do we really need one. In the future the communications channel will be much more complex in the services that it supplies, so yes, there will be automation there too. But for simple transponders, there is no need for complex handling techniques. And, don't forget Engineer Scott's observation, or perhaps it was a warning: "The more they overthink the plumbing, the easier it is to stop up the drain." Oscar-7 still works. Greg KO6TH Eric Fort wrote: > Yes, a zero hertz tone would be ideal if one were going to insert a tone for tracking. Not sure you?d need full carrier though. The advantage of a zero hertz tone is not having to notch it on rx, a ctcss tone is probably easier to generate on modern transceivers though. Having a (reduced) ?carrier? to measure and track would seem to be an aid to automated tuning of the receiver though. Sound card listens for the tone and adjusts rx frequency according to the offset from a known and agreed upon transmit tone. What I?m hearing here in the comments though and I?ll ask if this is correct.... is that the computational approach of adjustment based upon published elements is good enough.

The event is scheduled to begin at approximately 12:05 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between NA1SS and GB4KHS. The contact should be audible over the United Kingdom 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 Mars story of the school The Mars project, envisioned by a student after watching Tim Peake's 2016 mission, is our chance to inspire more girls while in their formative years, to consider studying science at A level and beyond. Since 1879 King's High Warwick has been championing girls in science and STEM subjects as one of the leading all-girls schools in the Midlands. The importance of girls' education back then was viewed as inferior to that of boys and the early headmistresses of King's set about trying to change that. Over a hundred years on girls and boy's education is viewed as equal, however the number of girls in science and STEM subjects is still not equal to our male counterparts; through school and into the workplace. Just 35% of girls choose maths, physics and computing compared to 94% of boys The Project One campus is the latest opportunity for King's girls, consisting of brand new school buildings on the Warwick School site. It will feature state of the art science labs, enabling future generations of girls to study with the best facilities possible. The future King's girls at the Prep and local schools will use these labs for their time at King's and we believe the Mars Project will inspire them to see what studying STEM can lead to, helped by access to high quality equipment. The project will assist in creating a collaborative relationship between the wide variety of subjects that have previously had minimal cross over in their syllabuses. The focus on Mars and astronomy links directly to the A Level Physics syllabus, inspiring more girls to study physics beyond GCSE. The supra-curricula activities conducted as a part of the project, such as building rovers in DT widen the educational experience of girls and enable them to see the real-life applications of their learning. Participants will ask as many of the following questions as time allows: 1. When we colonize Mars, what is the most important thing we need to learn from our ancestors' mistakes on Earth? 2. What types of weather can you get on Mars that we would have to tackle if humans were going to live there? 3. Considering the research into life support systems on the ISS and research into in-situ resource utilization, how long after the first manned mission to Mars do you think that a Mars colony can be self-sufficient? 4. Now that you are on the ISS would you have done anything differently during training, physically or mentally? 5. Having experienced the vastness of space, do you believe there are other forms of life in the universe? 6. How has your journey to space changed your perspective on human life? 7. What aspect of space travel do you think needs to be improved in the next 10 years to get us further into space? 8. What is the most magnificent place on Earth from space? 9. How does not having daylight or seasons in space affect you compared to being on Earth? 10. Is it true that the atmosphere changes your sense of taste up in space? 11. How does the feeling of weightlessness compare to the training underwater on Earth? 12. How far into the future is the technology needed to make travelling between solar systems the norm? 13. We all know space can be a dangerous environment. How do you and your fellow astronauts protect yourselves whilst on the ISS? 14. What does your training on Earth entail to help you cope with the effects of the lack of gravity on your sleep? 15. What part of nature do you miss most from Earth when you are in space? 16. How difficult is it for your body to adjust to life in space? 17. What?s the one thing that surprised you most when you first saw Earth from space? 18. What?s your advice to young people dreaming of becoming involved in space programs? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook.

Youll need to supply external batteries, unless 5w max is okay, in which case go for the FT-817ND (or the FT-818 if you want to buy new). I'd recommend buying both the 897 and an 817 for satellites, so you can hear yourself on the downlink and meet almost all your requirements radio-wise. On FM, you can get away with a pair of cheapy Baofeng handhelds. Antennas are another consideration; I'd recommend the Arrow II for satellite work, and an endfed for with a resonant wire for each band for HF portable.

Welcome. I've learned a lot from the people on this list; I'm sure you will, too. No doubt there are a lot of good answers to your question, but I couldn't be happier with my FT-857d. I believe it meets all the requirements you listed and I use it for many of the same modes & bands that you mentioned. On the subject of using two radios, that's exactly what I do. For linear sats, I use the FT-857d for transmit and an SDR to receive. For FM sats, I have a full-duplex capable FM transceiver or could certainly use an SDR to receive in that mode as well. However, I find that the FT-857d makes a great receive radio for the FM downlinks due to the DSP audio filtering and clarifier tuning (so that I'm not limited to following the downlink in fixed increments). Paired with a YT-100 tuner, Signalink-USB audio coupler, CAT control to my PC, and all mounted in a 4U Gator box, I'm able to use the same setup at home or vehicle-portable. (I have a 35ah battery in a separate box) Hope that helps! -Scott, K4KDR ========================================== On Mon, Apr 16, 2018 at 12:36 PM, Peter J.

There are several solutions, but two Yaesu 817s are very popular among a lot of the active portable ops. These allow full-duplex capabilities for SSB and FM satellites as well as 160m-432 MHz portable activity on all modes. If you?re willing to go QRP, this combo provides a lot of flexibility in a relatively small package. Others will chime in with suggestions as well. Glad to see you on the list!

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary.

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary.

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary. To sign up, go to https://ariss-proposal-webinar-spring-2018.eventbrite.com For more details such as expectations, proposal guidelines and the proposal form, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html ? ****************************************************************************** ARISS is always glad to receive listener reports for the above contacts.?

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary. To sign up, go to https://ariss-proposal-webinar-spring-2018.eventbrite.com For more details such as expectations, proposal guidelines and the proposal form, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html ? ****************************************************************************** ARISS is always glad to receive listener reports for the above contacts.?

Message-ID: <4bd9479f-ede2-99f6-f6c2-a220b6cbd53f@msa.hinet.net> Last week's ISS SSTV activity was a good way to see how my 2m DCA worked (hint: I was a bit disappointed). Testing your antenna in real world situations is difficult with satellites, because there are no signals around at will, like with terrestial beacons, of friendly fellow hams who want to test with you. The ISS activity provided a good opportunity to get at least a couple of reliable signals a day. I haven't been very successful in picking up much with my 70cm DCA, yet. I'm not expecting miracles, but it would be nice to at least see some traces of something on the waterfall of my Airspy Mini. So I was wondering, what are the strongest, most reliable beacons you can hear on 70cm that I can plug into Gpredict to track? So far I have come up with this: LO-19 - 437.125 MHz - carrier, but continuous. I've heard this one. FO-29 - 435.795 MHz - haven't heard this one yet. Active? Athenoxat-1 - 437.495 MHz - CW ID and I've heard this one faintly. RS-30 - 435.315 MHz - still active? Haven't heard this one. Lilacsat 2 - 437.200 MHz - listed, but active? Any additions to what beacons are active or inactive on 70cm are welcome. Both CW and FSK telemetry are fine.

It comes up whenever there is 10m HF PSK31 activity. SO, not guaranteed on every pass, but it does come up.

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary. To sign up, go to https://ariss-proposal-webinar-spring-2018.eventbrite.com For more details such as expectations, proposal guidelines and the proposal form, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html ? ****************************************************************************** ARISS is always glad to receive listener reports for the above contacts.?

In-Reply-To: References: Message-ID: Thanks for all of the interest but the Yaesu G-5500 azimuth rotator has already been sold....actually had 11 folks who wanted to buy it...but only had one of them and it went within afew hours of posting it on QRZ... I did want to clarify one thing based on one of the emails I received? I was not selling an elevation rotator for $250? Just the azimuth rotator. Apologies for my obviously ambiguous statement. What I was referencing is that the Yaesu parts department sells both the azimuth and the elevation G 5500 rotators for $250 each plus shipping of about $22. (They charge about $390 for the controller? These often sell on eBay for about $100? There was one selling for $79 a few days ago.) If you are considering repair or refurbishment of your rotator, my cost was $122 plus $63 for return shipping plus the $63 shipping costs for me to send the rotator and controller since they wanted both to make sure what the problem was. This equals a total cost of $248 for a refurbished one (which they ended up screwing up twice more with poor workmanship)? Versus $272 for a brand-new one with a one year warranty ? and it comes with a brand-new lower mast mount to boot ? and you don't end up with nearly 3 months of downtime off the satellites due to Yaesu's slow repair and screw ups. I know money can be tight but you might, just maybe, consider this arithmetic and $24 difference next time one of your G-5500 rotators fail. 73 de Robert K3RRR -.- ...-- .-. .-. .-. 73 de Robert K3RRR K3RRR.com <~~~~~~~~~~ Visit My Web Site @K3TripleR <~~~~~~~~~~ Follow Me On Twitter YouTube.com/K3RRR <~~ Check Out My Videos -.- ...-- .-. .-. .-.

In-Reply-To: References: <00fc01d3d6c0$f852d7c0$e8f88740$@verizon.net> Message-ID: Hi Tom, https://w4uoo.wordpress.com/sat/ I gave this at the Tampa Amateur Radio Club a few weeks back. Only covered 'Beginners' and FM. Drew - KO4MA joined me being local to us in the area, which gave the whole deal some great stories about what AMSAT is doing too. (I was grateful to have Drew along to give the gig credibility ) I didn't do Power Point, wanted it to be more accessible from a mobile device or tablet. I pitched this from my phone connected to a large display at the TARC clubhouse with an apple TV over wifi so I could also show satellite tracking from my phone and mailed the link to the club email reflector during the presentation so that all could have the information during the preso and the meeting. Its got a couple things I need to add like update your keps etc... There's a few new folks in the fray now as a result. Next I'll do a follow up on linear birds and working with a station that has az-el capability. Major emphasis ---> Make absolutely sure you can hear on several passes before you ever think about transmitting to get used to pointing the antenna, and, watch your ERP once you do transmit...and don't forget - Support AMSAT Use it if you like let us know how it goes. Good luck !

Several tracking programs and all required orbital parameters are available for tracking these satellites. But soon spacecraft carrying an amateur radio payload will be launched towards the Moon and beyond. If amateurs want to track these spacecraft they will need suitable tracking software and orbital elements to be able to calculate the positions of these spacecraft. Calculations Unfortunately none of the currently available tracking programs, used for satellite tracking by amateurs, is suitable for deep space tracking. But fortunately two free, open source software packages for Windows, Linux and Mac are available, that will enable deep space tracking: General Mission Analysis Tool (GMAT) http://gmatcentral.org/ https://sourceforge.net/projects/gmat/files/GMAT/GMAT-R2017a/ SciLab, including CelestLab, CelestLabX and Aerospace Blockset http://www.scilab.org/ http://atoms.scilab.org/toolboxes/celestlab https://atoms.scilab.org/toolboxes/aerospace_blockset Probably most amateurs will prefer GMAT, because it is most user friendly, has a lot of documentation and help files, and contains many sample scripts. Scripts that are created by other amateurs can be used without having much knowledge or experience with GMAT. Measurements It is not certain that orbital elements for all deep space spacecraft carrying amateur radio payloads will be made available to radio amateurs. Therefore amateurs may need to measure these orbital elements themselves through doppler and ranging measurements. So amateurs will need to set up their own Amateur Deep Space Network, similar to NASA's DSN, ESA's Estrack, etc. This will require some stations with large enough antennas and with equipment to carry out doppler and ranging measurements to determine direction and distance to the spacecraft. This new development is an interesting challenge for radio amateurs. For further details see my Amateur Deep Space Tracking page: https://hamsat1.home.xs4all.nl/index.html You can find further information on space flight on this very informative set of pages: https://solarsystem.nasa.gov/basics/ Deep space navigation is covered in chapter 13: https://solarsystem.nasa.gov/basics/chapter13-1/ 73, Nico PA0DLO From pe0sat at vgnet.nl Sat Apr 21 19:21:11 2018 From: pe0sat at vgnet.nl (PE0SAT | Amateur Radio) Date: Sat, 21 Apr 2018 21:21:11 +0200 Subject: [amsat-bb] Amateur Deep Space Tracking In-Reply-To: References: Message-ID: <98c47308142fb25ae4988d5ec8667eb1@vgnet.nl> Thanks Nico, Great information! 73 Jan PE0SAT On 21-04-2018 16:56, Nico Janssen wrote: > All, > > Many radio amateurs are familiar with tracking amateur satellites > that orbit the Earth in low orbits or high elliptical orbits. > Several tracking programs and all required orbital parameters are > available for tracking these satellites. > > But soon spacecraft carrying an amateur radio payload will be > launched towards the Moon and beyond.

April 22, 2018 To All RADIO AMATEURS BID: $ANS-112.01 FCC votes to issue NPRM that proposes to streamline licensing of "small satellites" On April 17th, the FCC began taking steps to streamline the application process for a category of satellites known as ?small satellites?. This action proposes a more accessible and flexible authorization process for this fast-growing segment of the commercial satellite communications market. Many small satellites are launched not as large constellations, but as part of small-scale operations consisting of a single satellite or only a few satellites. Small satellite systems have been used for scientific and research missions, and they are now increasingly used for commercial endeavors. Given recent innovation in the small satellite sector and the increasing number of proposals for commercial operation, the Notice of Proposed Rulemaking adopted today proposes a new authorization process within Part 25 of the Commission?s rules to govern satellite licensing that is tailored to small satellite operations. This new process will address current needs in this evolving industry sector, as existing Commission licensing rules and processes were not developed with these types of systems in mind. Specifically, the proposal would allow the new process to be used by satellites with certain characteristics, such as having a short on-orbit lifetime, being able to readily share spectrum with other operations, and having a mission profile that demonstrates a low risk of orbital debris. Today?s action also looks at the spectrum needs of short duration small satellites, including inviting comment on operations of small satellites in certain frequency bands currently allocated for satellite services. The NPRM also considers revising the application fee for small satellites applying under the new streamlined process. It is unknown how or even if this NPRM (FCC-18-44) will affect the amateur satellite service which is under Part 97 of the FCC's rules. AMSAT-NA and other amateur radio advocacy organizations will be following this closely.

We are currently running the detailed examination regarding the causes of loss. Sorry for the long delay with an answer - we did not want to report unverified information.'' D-STAR One Phoenix, a U/u satellite using the JARL D-STAR digital voice protocol, was launched on a Roskosmos Soyuz-2 on 2018-02-01. It replaced a similar spacecraft launched on a Roskosmos launcher in November of 2017 that did not make it to orbit due to a problem with the launcher. On April 20, German Orbital Systems that they plan to launch three more D-STAR-based cubesats by the end of the year: ``"The third is a good one" proverb says. Well, dear #radioamateur community, we announce that new #DSTAR mission is planned for the end of this year. And, to ensure, that it will be successful, we will launch not one, but THREE D-Star #cubesats. Whole constellation for you guys'' [ANS thanks German Orbital Systems Twitter/@GermanOrbital for the above information] --------------------------------------------------------------------- AMSAT @ Hamvention - Get Your Questions Answered in our Beginner's Corner This year Hamvention 2018 runs May 18-20 at the Greene County Expo Center in Xenia, Ohio. AMSAT has indoor display space in Booths 1007-1010, 1107-1110 - an entire aisle dedicated for Amateur Radio in Space. As AMSAT President, Joe Spier, K6WAO recently noted, "Hamvention is amateur radio's premier gathering in North America. AMSAT's presence is important because it not only provides a venue to interact with our members and those interested in amateur radio satellites, but it also provides an opportunity to engage those that may not currently be active with satellites. Our mantra is "Keeping Amateur Radio In Space" but we also need to be diligent about that mantra in front of thousands of amateurs who attend Hamvention. Our Hamvention presence builds awareness, generates revenue, and lays the foundation for future support." AMSAT will offer the latest materials at the booth this year, including a 2018 edition of Getting Started with Amateur Satellites, as well as the latest in "satellite fashions." We'll once again provide a "Beginner's Corner" where we will answer questions about amateur radio satellites and communications. You'll see demonstrations of SatPC32 and MacDoppler satellite tracking software, and get your operational questions answered. Get one-on-one guidance on setting up your satellite station and making contacts. Amateur Satellite operation demonstrations will be held every day outside the main Maxim Hall (Building 1 or E1) entrance. AMSAT will be demonstrating actual contacts with the operational amateur satellites. We especially invite youth to make a contact via an amateur satellite. All are invited to observe, participate and ask questions. Satellite pass times will be posted at the AMSAT booth and in the demo area. This gives you the opportunity to get satellite station and operating tips from some of the best satellite operators in the country!

March 15, 2018: The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio. The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program's goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, "ARISS shows how Amateur Radio is the most unique hobby/service there is." Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, "It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!" Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, "This chance for our school's ARISS contact helped me see the great value of the ham world. I just passed my Technician License this weekend and have already signed up to take a General class." ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 1900 EDT and April 16, 2018, at 1600 EDT.

PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Facebook: "Amateur Radio on the International Space Station (ARISS)". Twitter/@ARISS_status Web: http://ariss.org/ 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.

His ?Horizons? mission is aimed at evoking exploration of the universe, looking far beyond Earth and broadening knowledge. His first mission was called ?Blue Dot.? A citizen of Germany, Gerst will launch on June 6 from Kazakhstan with US astronaut Serena Au??n-Chancellor and Russian cosmonaut Sergei Prokopyev aboard a Soyuz MS-09 spacecraft. Gerst will take over command of the ISS for the second half of his mission, marking only the second time that a European astronaut will assume the top ISS leadership post. Gerst first served on the ISS in 2014 as part of the Expedition 41/42 crew increment. Gerst likely would use the ISS?s DP0ISS call sign for any Amateur Radio on the International Space Station (ARISS) activities.

We have strong local noise on VHF at the AO91 and 91 frequencies so those are off the list. Morning passes here on any sat have pretty much no one on them. We are having great success with FO29 (a workhouse). We are also able to work AO7 and in fact worked a handful of Europe stations there the other day. Pretty awesome - especially since I'd never been on AO7 before. Downlink is hard to hear but it's workable. So the plan is to concentrate on SO50 (to the extent someone else is not using all the bandwidth), FO29, and AO7 when SA or NA are in the footprint. Again, FO29 is working great. Be glad to work all comers there. And *please* don't tune your uplink while calling us. It's impossible to track you across the passband, point the antenna, turn for normal Doppler, paper log, all at the same time. We are happy to tune for you if you stay put on 145.840 - which is where we are. The other guys are helping with the antenna when possible but not always. Thanks for your patience as we fumble through this. We have about 60ish sat contacts. Three more days on island. Hot, humid, breezy to strongly windy , and HF bands the pits. Mostly FT8 and CW on 20, 30, 40, occasionally 17 (plus possible 80 tonight). Will do SSB on HF when conditions allow. Good long run on 40 SSB into mostly US last night and hopefully tonight about 0000Z. Jim, WD0E From St. Barts.

I hope someone can help me out. I've been trying to work the transponder satellites using CW (Morse) for some time.? I use satpc32 for the tracking program and a Kenwood TS-2000X.? I've been able to hear my downlink signal by using transmit RIT to find the signal. At that point, satpc32 tracks the Doppler and keeps the signal where I have it set, within a few Hertz. I've called CQ a lot with no responses.? A couple of times I heard CW but the signal just drifted across where I was at, from lower to higher frequency. What might I be doing wrong?? Or is there just not much activity on Morse? I haven't heard much SSB or FM on the FM birds but what I've heard I've been unable to work anyone.?

Tadeusza Kosciuszki w Lasku, Lask, Poland; and Zesp?l Szk?l Ponadgimnazjalnych w Zelowie, Zel?w, Poland on 26 Apr. The event is scheduled to begin at approximately 10:52 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between OR4ISS and SP7KYL. The contact should be audible over the country of Poland 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. Three schools participate in one ARISS school contact. The Complex of High Schools in Zel?w and The 1st High School in Lask were invited to cooperate with the main organizer of the event - The Complex of the Primary School and the Junior High School in Buczek, because students from one school very often continue their education in another school on the next educational level. These three schools are an example of education levels in Poland. They are situated in the central part of Poland. The Complex of the Primary School and the Junior High School (Zesp?l Szkoly Podstawowej i Publicznego Gimnazjum) in Buczek is a primary school together with a secondary school. Since 2016 the school has been changed into one - Primary School. It is a community school located in the center of Poland. The school was built in 1950, there are 18 classrooms, 2 IT rooms, a canteen, two ordinary gym rooms and one newly constructed modern gym. There are 369 students at school and highly educated staff. The school is known for its safety, warmth, friendship and working together. Zel?w is located about 6 km from Buczek. The Complex of High Schools (Zesp?l Szk?l Og?lnoksztalcacych ) in Zel?w consists of the primary school, junior school, and secondary school. The secondary school was built in 1957, whereas in 1999 the Complex of schools have been established. There are 23 classrooms, modern library assembly hall, gym, sports ground and observatory equipped with the camera registering bolides and transferring the data to the Polish Bolides Net. 363 students attend our school. The school is famous for realizing various projects and cooperation with different organizations, i.e. Amnesty International. Since 2017 teachers and students have been participating in the program Erasmus+. Lask is located about 10km from Buczek and about 15km from Zelow. The 1st High School (I Liceum Og?lnoksztalcace im. Tadeusza Kosciuszki) in Lask is the oldest Polish secondary school in this city. It is an outstanding didactic institution which has been sustaining the highest level of education as well as the place of particular aura, where all the graduates have been talking with pleasure and sentiment about. Having worked for years with the original methods with talented students has contributed to the high place of our school in the national school rankings. This success is owed to the plenty of students who have won diverse contests in different subjects. Graduated students continue higher education studying. The Amateur Radio Club SP7KYL is Association of Communication Section of Sport and Recreation JUPITER of Belchat?w Power Plant. The Club unites 10 actively working licensed amateurs radio members. The club was founded in 1980. The Club launched and take care of two amateur radio analogous repeaters SR7E (2m) and SR7EB (70cm). The club is also co-organizer of national HAM radio technical meetings: SP-QRP Workshops (2007-2011) and The Technical Shortwave Convent (Zjazd Techniczny Krotkofalowcow) in Burzenin (since 2012). Members from this clubs visited and installed HAM radio equipment in each of mentioned schools to give their students a unique opportunity to talk by HAM radio. Participants will ask as many of the following questions as time allows: 1. What was the most interesting occurrence that you came across during your space trip and at the space station? 2. What are scientific experiments carried out on the space station at present? 3. Can you describe how did the aurora looked like from the ISS and what did you feel when you saw it the first time? 4. Does being in space contribute to a faster aging of cells? 5. What do astronauts feel while approaching earth during the return? 6. What do you think about the importance of a HAM radio school contacts? 7. How do astronauts weld metals while repairing broken ISS station? 8. How do you keep in touch with your family? 9. What do you do on the International Space Station if one of you gets ill and, for example, needs to have an immediate surgical removal of an appendix? 10. How often do you have to correct the ISS orbit to avoid space trash? 11. Which skills are the most important to become an astronaut? 12. Is it hard to get used to weightlessness? 13. What is your biggest dislike being in space? 14. How well does your training help you to cope with the mental and physical changes that occur on travel to and from space? 15. What is the maximum duration that your mission in space can be? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook.

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.

Youll need to supply external batteries, unless 5w max is okay, in which case go for the FT-817ND (or the FT-818 if you want to buy new). I'd recommend buying both the 897 and an 817 for satellites, so you can hear yourself on the downlink and meet almost all your requirements radio-wise. On FM, you can get away with a pair of cheapy Baofeng handhelds. Antennas are another consideration; I'd recommend the Arrow II for satellite work, and an endfed for with a resonant wire for each band for HF portable.

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary.

Here is a summary of the various option, plus description of my ultimate choice. There were several good options: Paul W2HRO suggested Sector Microwave SM7 switches. Uses N-Type connectors, will handle 1200 watts or more on 2 meters: A Cadillac option with $225 price tag. Eduardo PY2RN sent a link to a PDF showing different options using manual coax switches and/or multiple Diplexers. Burt FG8OJ sent an eBay link to a $10 NAIS ARD62024 transfer switch - this was the option I decided to pursue. The ARD62024M01 has four SMA Female jacks, handles 120 watts at 3 GHz, has .2 dB insertion loss at 1 GHz, and has gold plated contacts. It is about 1.3 inches by 1.3 inches by 1.8 inches, or 32mm x 32mm x 39 mm (46mm including SMA jacks). The 24 at the end of the part number means it is a 24 volt relay. This is a latching switch, so momentary application of voltage to one wire switches and latches it to Position 1, momentarily applying voltage to another wire switches and latches it to Position 2, In Position 1: J1 <=> J2 and J3 <=> J4 In Position 2: J1 <=> J3 and J2 <=> J4. So I put the 2 meter antenna on J1, 70 cm antenna on J4, the receiver on J2 and transmitter on J3. So in Position-1 the 2 meter antenna is on the Receiver and 70 cm antenna is on the Transmitter. In Position-2, the 2 meter antenna is on the Transmitter and 70 cm antenna is on the Receiver. Add a pair of momentary-on push button switches: one energizes the latching relays into Position 1 (u/V), the other energizes the latching relays into Position 2 (V/u). I purchased 3 foot cables SMA Male on one end of all 4 cables, with the other end of one a PL259 for my Yaesu FT-897 (used for xmit), two with SO-239s for the 70 cm and 2 meter antennas, one with SMA-Male for the Funcube Dongle Pro Plus receiver. It works great - I love the latching relay concept. That way a failure of the power supply won't cause the antenna to flip from U/V to V/U, or vice versa. Total cost was about $85, $17 for each of the four cables and $10 for the coaxial switch plus shipping. Here is a link to the data sheet: http://www.relaymall.co.kr/pdf/mech_eng_rd.pdf Thanks again to all for the great ideas! 73 Rolf NR0T Grid EN34 . . .

It is time to be creating your shopping list and making your travel plans. Last year, we had 30 people assist with the AMSAT booth at the Hamvention. We've had a good response so far to our first call for volunteers, but we could really use another 10-15 people. The 2018 Hamvention is May 18-20 in Xenia, Ohio.? Would you consider helping AMSAT at the Hamvention this year? The interaction with AMSAT members, satellite operators, designers, and builders makes the whole experience a lot of fun.? Meet or renew acquaintances, exchange operating tips, and find out what antennas, software and equipment other AMSAT members use.? We currently expect all of the AMSAT senior officers and board members to be there too. If you're an experienced operator, great!? We can use you and your experience. If you've never operated a satellite before, but want to learn more, that's OK. We can use your help too. Whether you're available for only a couple of hours or if you can spend the entire weekend with us, your help would be greatly appreciated. Please send an e-mail to Phil, w1eme at amsat.org if you can help. Thank you!

King?s High School strongly encourage their girls to develop their interests both inside and outside the classroom. This culture of empowerment led one of their girls, Eleanor Griffin, to apply to ARISS Europe (Amateur Radio on the International Space Station) for a highly prestigious link-up to the International Space Station. When Eleanor Griffin was selected to hold a space conversation with an astronaut, she was inspired to set up the Warwick Mars Project, for students across the Warwick Independent Schools Foundation, to further interest in Space Science. Eleanor says: ?The moon landings belong to the generation of our grandparents, and the International Space Station to our parents. What will happen in our generation? Will Mankind travel to another planet?? After the ISS contact when asked what this incredible experience had taught her Eleanor replied ?Just do it! No one is going to stop you, if you just go and pursue your dreams, you really can do anything.? Watch the BBC TV news item broadcast on Midlands Today @bbcmtd.

Someone else may be able to help with your exact question, but please know that you don't HAVE to use the full WiSP suite of software to use the BBS on Falconsat-3. What I mean is, you can use your existing software to track the orbit as well as something like UISS (or an 9k6 APRS-capable HT) to utilize the APRS digipeater. For the BBS specifically, only the MSPE component of the WiSP suite is needed once you have used the GSC application in WiSP to define the parameters of the satellite and your TNC -or- soundmodem connection. Here is a link with a great amount of detail on how all the parts work: http://www.qsl.net/py4zbz/falconsat.htm And if you would like to see the software work "live", here are a couple of VERY rough videos that I did to help individuals who have reached out for guidance on FS-3. They are not polished like so many of the great videos out there on Amateur Radio topics, but I'm glad to share on the chance that they might get you up & running more quickly. http://www.qsl.net/k/k4kdr//video/FS-3_demo.mp4 (no sound) http://www.qsl.net/k/k4kdr//video/FS-3_Settings.mp4 73! -Scott, K4KDR =========================== On Sun, Apr 29, 2018 at 3:00 AM, Vincenzo Mone wrote: > Hello, > anybody can tell me where can I get the update keps for the Falconsat-3 > that > works with wisp? > I have tried to create a txt file with just the Falconsat one but when I > try > to upload in the GSC program, > I get "No Satellite Found". > > Also is there a tutorial and needs how to operate with it? > Thanks > > 73's de Enzo IK8OZV > EasyLog 5 BetaTester > EasyLog PDA BetaTester > WinBollet BetaTester > D.C.I.

ARISS-US program education proposal deadline is April 30, 2018 ? March 15, 2018:? The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019. ? Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio.? The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program?s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, ?ARISS shows how Amateur Radio is the most unique hobby/service there is.? ? Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, ?It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!? Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, ?This chance for our school?s ARISS contact helped me see the great value of the ham world.? I just passed my Technician License this weekend and have already signed up to take a General class.?? ? ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary.
