From k.alexander at rogers.com Sat Apr 1 00:24:11 2017 From: k.alexander at rogers.com (Ken Alexander) Date: Fri, 31 Mar 2017 20:24:11 -0400 Subject: [amsat-bb] Problems with my Arrow Message-ID: <5d9adbe0-cd7e-19e9-a186-604baaefe552@rogers.com> I just checked the SWR using my FT-817ND's built in meter. I connected directly from the 817 to the appropriate connector on the Arrow. At 435 MHz the SWR meter shows 5 bars, which doesn't sound good to me. At 145 MHz I get a very brief indication of 6(?) bars and then the the bars immediately disappear. This sounds to me like a protection circuit engaging, and subsequent presses of the mic button produces no output. It also explains why I practically never get into SO-50. The FT-817 manual is silent on the meaning of the bars on the SWR meter. Does anybody have an knowledge of the 817's SWR meter that they could pass along to me? Any assistance would be very gratefully received!

DATE April 2, 2017 To All RADIO AMATEURS BID: $ANS-092.01 ITF-2 Team Begins Normal Operations and Offers Awards ITF-2 (YUI-2) entered normal operation phase on Mar 25th JST. Telemetry information and messages will be transmitted in this phase for the achievement of main mission. The details of the AWARD and SWL cards are as below, AWARD: With reference to the message on Jan 15th UTC, the First 100 Reports from overseas stations are qualified for this award. Only ten overseas stations sent report so far. Still enough award can be issued. Additionally, a souvenir, a sticky screen cleaner, will be given with this award. The design motif is the small antenna of ITF-2. Design of the cleaner: https://twitter.com/yui_tsukuba/status/841096655046758400 SWL cards: Five designs are prepared. The stations which report more than five times can receive all designs. Also, the specially designed card will be presented to the stations which received a signal from the small antenna, because the reports are valuable to demonstrate the antenna in space. So far, two stations succeeded in the reception. Designs of SWL cards: https://twitter.com/yui_tsukuba/status/846219342190555136 Further special events are planned for the promotion of receptions by more stations. There were some reception reports by very simple equipment, for example, Dipole or 5/8 wave length whip with USB tuner dongle (RTL2832).

The 20-minute, Earth-to-space call will air live on NASA Television and the agency's website. (n.b. - this is not an ARISS contact via amateur radio) Expedition 50 Commander Shane Kimbrough and Flight Engineer Peggy Whitson, both of NASA, will answer questions from students in several grades. Students at Betsy Ross Elementary School have been hard at work exploring the space program, NASA and the space station leading up to the downlink. They have conducted research through virtual field trips while also designing realistic models of the space station. With each engaging activity, the students' knowledge of NASA and the space program has been greatly enhanced. Kimbrough launched to the space station Oct. 19, 2016, and will return April 10. Whitson launched to the space station Nov. 17, 2016, and is scheduled to return to Earth later this spring. Media interested in covering the event should contact Keith Sterling, director of communications & public information, Anaheim Elementary School District, at 714-600-0952 or ksterling at anaheimelementary.org. Ross Elementary is at 535 S. Walnut Street in Anaheim. Linking students directly to astronauts aboard the space station provides unique, authentic experiences designed to enhance student learning, performance and interest in science, technology, engineering and mathematics (STEM). This in-flight education downlink is an integral component of NASA Education's STEM on Station activity, which provides a variety of space station resources and opportunities to students and educators.

The NASA Image and Video Library website consolidates imagery spread across more than 60 collections into one searchable location. https://images.nasa.gov NASA Image and Video Library allows users to search, discover and download a treasure trove of more than 140,000 NASA images, videos and audio files from across the agency?s many missions in aeronautics, astrophysics, Earth science, human spaceflight, and more. Users now can embed content in their own sites and choose from multiple resolutions to download. The website also displays the metadata associated with images. Users can browse the agency?s most recently uploaded files, as well as discover historic and the most popularly searched images, audio files and videos. Other features include: + Automatically scales the interface for mobile phones and tablets + Displays the EXIF/camera data that includes exposure, lens used, and other information, when available from the original image + Allows for easy public access to high resolution files + All video includes a downloadable caption file NASA Image and Video Library?s Application Programmers Interface (API) allows automation of imagery uploads for NASA, and gives members of the public the ability to embed content in their own sites and applications. This public site runs on NASA?s cloud native ?infrastructure-as-a-code? technology enabling on-demand use in the cloud. The library is not comprehensive, but rather provides the best of what NASA makes publicly available from a single point of presence on the web. Additionally, it is a living website, where new and archival images, video and audio files continually will be added.

As described in the SatPC32 FAQ: *k. Ole error 8004503A??* The SatPC32 voice feature requires the Microsoft Speech SDK (SAPI 5.1) to be installed on the PC. If it is missing you will get the aforementioned error message. The software can be downloaded for free from the Microsoft web site: http://www.microsoft.com/reader/developers/downloads/tts.mspx See also: http://www.microsoft.com/downloads/details.aspx?FamilyID=5e86ec97-40a7-453f-b0ee-6583171b4530&DisplayLang=en Note that the first link is no longer active. The second link is. However, after you click the download button, a number of different files are listed for downloading. I downloaded and installed the SpeechSDK51.exe file. The description for it is: If you want to download sample code, documentation, SAPI, and the U.S. English Speech engines for development purposes, download the Speech SDK 5.1 file (SpeechSDK51.exe). There are other options available. I was tempted to try the: * If you want to redistribute the Speech API and/or the Speech engines to integrate and ship as a part of your product, download the Speech 5.1 SDK Redistributables file (SpeechSDK51MSM.exe). option, but didn't. Perhaps Eric can clarify which is more appropriate. I was doing all this via a remote desktop connection to the PC and all appeared correct, but when I ran it directly on the computer, I got the Ole error 8004503A..... error. I then found out I had to plug in a headset to the audio out connector on the PC to eliminate the error. Apparently my remote desktop connection "Remote Audio" enabled was enough for the SDK to run correctly. While installing via remote desktop, I also had to provide a path to the satellite group and Kepler files for some reason in the applications roaming directory. I was prompted for this via German language pop up windows. This issue is unrelated to the Ole error. 73, Bill NJ1H On 4/2/2017 10:17 AM, Erich Eichmann wrote: > > Bob, as Alan asked already: What is the number of the OLE error? > The only one of these kind of errors I heard about is Ole error > 800453A, see FAQs file fig. 5k. > Under Windows 7 and later the message appears if no speakers or > headphones are plugged into the computer. > 73s, Erich, DK1TB > > > ** > > Am 02.04.2017 um 03:38 schrieb Bob- W7LRD: >> What does this mean?

Please see below for all FUNcube mission info 73s Graham G3VZV and the FUNcube team. ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Lower temperatures give higher freqs!) FUNcube-2 (aka FUNcube on UKube) The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/ EO88/Nayif-1/FUNcube-5 EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, ie the solar panels are NOT being illuminated. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. The transponder frequencies are: Uplink: 435.045 ? 435.015 MHz LSB (inverting) Downlink: 145.960-145.990 MHz USB Telemetry Tx: 145.940MHz All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very grateful for the assistance given by Innovative Solution In Space Bv, The Netherlands. _______________________________________________ Sent via AMSAT-BB at amsat.org.

This email is to humbly request the opinions of those in the Amateur Satellite Community about the idea of setting new satellite DX records. Nothing formal, you can email on list or off list as you think appropriate. So here is the idea: What if there were a constellation of three satellites (3 1Us), built by students (undergrads) at three different universities, but launched together and deployed from the same deployer that had crosslink packet communications built into the design. Then, what if those birds were licensed via the Amateur Radio route (instead of Experimental as is the norm for most University birds, with some notable exceptions of course) allowing the entire global amateur satellite community to use the crosslink capability in an attempt to set new satellite DX records? Now, there is a primary science mission (pseudo-range determination as the constellation separates, different mass and drag profiles for each bird) so during the work week, science happens, but on the weekends, the constellation is made available to the community for crosslink packet comms. Additionally, if your setup has enough G/T to monitor the lower power crosslink comms, and with a little bit of technical tweaking to your ground station (you would need GPS based PPS to measure propagation time, maybe ~$100 invested), you could participate in Space to Earth pseudo-range measurements that would contribute to a secondary orbit determination goal. To be clear, the up and down linking for the satellite DX attempts would be standard FSK9600, AX.25, so as long as your station can do that, you can use the crosslink path for multi-hop comms. Its only the S-to-E pseudo range measurement that would require a bit of additional HW. Does this sound interesting? Would you as an operator be interested in multi-hop satellite packet comms? Do you think this type of operating schedule is acceptable (weekends) to justify Amateur Radio licensing instead of Experimental? Would you be interested in contributing to the science mission (S-to-E pseudo-range measurement)? Would you track the telemetry downlinks and forward that data on to the mission data warehouse? Any and all opinions, good or bad, are welcome. Again, on or off list as you see appropriate is fine with me. My goal with this is to get a sense of what the community's opinion on this topic is and if the constellation were available for use, how much interest there would be in this type of operation.

But here is the spirit of the idea to try to answer your question (specifically about packet crosslink comms, not the S-E range measurements): One decision that has been made is the Astrodev Lithium radio on UHF frequencies (radios have been bought). Single UHF frequency per bird for uplinking and downlinking on (half duplex). A second common/shared UHF freq for the crosslink. FSK9600/AX.25 UI for all up and down links (I'm 99% sure the Lithium can't do AFSK1200, but still investigating, and if anyone on the list has experience with the Lithium I'm all ears). Crosslink radio is the RFM69HCW, which is similar to MO-76's RFM22 radio, also on UHF freqs. So a definitely frequency incompatibility with existing APRS fleet. Other than the frequency incompatibility though, when switched into 'weekend ops' mode, it would likely be standard FSK9600 up and down, AX.25 UI Frame, and APRS 'encoded' packets from/to the ground. The crosslink is a more custom link that would be 'transparent' to the operator. It is still FSK9600, but not AX.25 (based on RFM69HCW chips capabilities). The students are currently playing with prototypes to work out the specifics for the crosslink data format. Its easier to use the built in 'packet mode' on the chips, but more flexible (and harder) to use the 'transparent mode.' We're currently examining both options. So FSK9600/AX.25 UI/APRS encoded up, data decoded and updated per APRS digipeat standards, APRS message encapsulated for transport across the RFM69 crosslink, then APRS message updated again at the next satellite, then downlinked in FSK9600/AX.25 UI/APRS format. The original receiving bird will possibly also digipeat on the Lithium radio as well as sending to the crosslink radio to 'confirm' reception of the uplink, since the crosslink will be different freq, different protocol, still TBD though. so 3 freqs (one up, one across, one down), probably two protocols (one for up/down, one for across). As far as software/hardware goes on the ground, standard TNCs capable of 9600 baud comms should work, much like the current operating mode for ARISS packet. So D700s/710s for sure should be able to play, as well as any radio with a 9600 baud data jack (and standard AX.25 TNC) should also work. Any APRS software driving the TNC should work as well. My hope is that any 'special software' that might ride on top of that would be available on github for the interested user (likely derived from the open source Fox Dashboard currently out there, but again, undergrad student project here). For those interested in the S-to-E measurements, with enough G/T, some recommended HW would need to be obtained (according to a 'User Guide,' still to be written, but basically some cheap parts from Adafruit/Sparkfun) and the same Dashboard mentioned above would have the relevant code to use that HW and obtain the data and forward on to our servers. Hope that helps clarify the CONOP. -Zach, KJ4QLP Research Associate Aerospace Systems Lab Ted & Karyn Hume Center for National Security & Technology Virginia Polytechnic Institute & State University Work Phone: 540-231-4174 Cell Phone: 540-808-6305 On 4/2/2017 4:42 PM, John Brier wrote: > Would it/could it/should it use the standard APRS mode on 145.825 MHz > with ARISS path to take advantage of the ISS and PSAT digipeaters? > That could allow for longer/more robust sat DX opportunities.

In the past, I have been involved with 2-HOP and 3-HOP packet attempts using various combinations of the ISS, NO-44 and NO-84 when they were all working on 145.825MHz. Your proposal of using a 9K6 FSK 2-port_digi's on board three satellites in the same orbital track resolves what I believe to be the main challenges we faced in our 1200 baud experiment. If the footprints overlap, the satellites should be able to talk to each other. 1) Since the satellites were in different orbits, there was Doppler shift in the signal between them. In your proposal, doppler is minimal for FM packet. 2) With your 2-port digi, the repeated packets between satellites will not be interfered with by multiple up link signals. Improving the success rate. 3) I find that 9K6_FSK is as easy to copy as 1200baud, so efficiency in channel usage is gained. Once the operators acquire confidence in establishing basic 2 & 3 Hop packet contacts, the other experiments and distance records you mentioned will follow. I'm in.....

Is the "long distance record" truly an academic goal? I hope that this is just a side effect of a more scientific endeavour :-) 2. How will the deployment of the satellites being scheduled? Too close together means long time for separation to make it useful but longer lifetime for use. Too much initially separation and the satellites won't see each other for too long. 3. How about the deployment altitude. The higher the better? 4. What happens to the sat in the middle, just a link between the other ones and no direct contact/use? 5. How can the system be programmed that if one satellites fails it still works? 6. Why 1Us and not bigger for better power budget and redundancies?

No, not really a an academic goal. But cross linking is a requirement. And pseudo-range determination is a requirement. So, 'distance records' or at least multi-hop comms are a natural extension. 2. 3 1Us in a single P-POD. But, different drag profiles and different masses. One has a drag brake that will be deployed shortly after deployment from the PPOD and after initial checkout. The other two have the same profile but different masses. 3. Aiming for an ISS deployment. Overall science goal is to generate data for atmospheric density models at LEO and low LEO altitudes. So higher would be better for the crosslinking/distance, but would be worse for the science. So it will be a relatively short mission, current estimates on the order of 6 months or so. 4. We're still sorting out the exact operating details. Earlier I gave a two satellite example, simplest case. We'll see how complicated we can make it as we move forward. One options is up to one, across to the other two, and down from both. Another is the triple hop (the really desirable one), where each time it hits a new bird, it gets sent on the crosslink and on the downlink. We don't have a specific plan yet, which is part of why I sent out the survey request, to see what people would be interested in, if at all, so we can try to incorporate it into the design. 5. yesss!!! different modes, different options, different ways to reconfigure, either from the ground or with built in 'fallback' operating modes. All the kind of things we're discussing and working through, but are leaving to the students to decide / figure out. I'm only a faculty advisor on the project, so can lob recommendations at my team, but I'm not in charge. We know for a fact (or are at least really really sure) that we will almost certainly lose one of them (the one with the drag brake) faster than the others. So the comms will need to be able to adapt. 6. Thats all the money we could drum up for the mission. But we'll take it, and are grateful for the chance here! I'm just hoping we can balance power budgets appropriately, cause yeah, its tight. -Zach, KJ4QLP Research Associate Aerospace Systems Lab Ted & Karyn Hume Center for National Security & Technology Virginia Polytechnic Institute & State University Work Phone: 540-231-4174 Cell Phone: 540-808-6305 On 4/2/2017 7:12 PM, Stefan Wagener wrote: > A few quick thoughts: > > 1.

It is only after the satellites spread out that distant stations will be needed to confirm the multi-hop. Certainly it takes a DX station for a DX contact.

Images of Battle Bots in Space coming to mind... Given that UHF is less efficient for distance contacts (at least by the physics), and that you'll be running the linking radios at a low power level, what sort of distance between the satellites do you expect to maintain contact? I'm presuming that the cubes are not going to be actively stabilized, and that the antennas will be more-or-less omnidirectional. Which brings up the last thought... As the satellites spin, their respective antenna polarizations will rotate with them. How will the satellites deal with cross polarization effects (20-ish dB loss)? Given a random polarization between any two satellites, plus the 70cm path loss penalty, the chances of getting through all 3 birds once they separate could be vanishingly small, no? Still, we're getting quite a flury of reports recently of FunCube telemetry via FO-29, so it is certainly possible for this to work. Suggestion might be to figure out why FunCube to FO-29 is working, and make sure that is part of your design. Good luck!

I think the simple answer that I was looking for is that generally yes there is interest from the community. Below is my attempt to answer multiple questions/points from the numerous (and appreciated!) comments and questions (some overlap): 1. Technically the universities involved are not competing, we are cooperating (weekly telecons, ICDs, etc. etc.). Not 3 cubesats designed in a vacuum (hi hi) the magically working together. Three designs that are done individually by the institutions, but with open lines of communication between the respective design teams and subsystem teams (turns out things are cheaper when you buy in bulk too!). That being said, if you ever eavesdrop on those phone calls, sometimes it might sound like competition.......but not unexpected, good lesson in teamwork for the students (and faculty.....). 2. combination of active and passive stabilization is *planned.* I have yet to get the 'warm and fuzzy' feeling concerning the active stabilization bounced against the power budget. 3. Concerning expected ranges..........good question, thats a bit what the experiment is all about. We're hoping for a few tens of kilometers, 100km is probably a stretch (OK so maybe not satellite DX per se). One path I have the students going down is tradeoffs between crosslink radio 'modes of operation.' The RFM69HCW has power control, baud rate control, channel filter BW control, and RX gain control (which affects linearity and Noise Figure). So maybe as things get further and further, FSK9600 becomes, FSK48000, then FSK2400, then FSK1200. Maybe that is tied to a bit of power control where before we drop back in baud rate we have reached peak power output. Likely not an 'automagic' decision made onboard, likely all three get commanded to the new modes of operation by ground. We'll see..........which reminds me, the students owe me link budgets........ 3.b Also, as a super-rough back of the envelope, MO-76 links were closing with Arrow antennas on the ground when the slant range was on the order of around 800km. Assume ~12 dB of gain from the arrow, and the loss of 6dB for doubling of slant range. So if we go from an Arrow to a 0 dBi antenna, we've cut our range by a quarter (two 6dB losses in the link) so looking at 200km. BUT MO-76 was low bit rate and various modulation schemes, some of which are very narrow (like CW). So accounting for increased bandwidth, and polarization mismatches..........we'll be happy with a few 10s of km. 4. #s 1, 2, and 3(b) are hinging in large part on simulations in AGI's STK. First step for the undergrads: learn how to use STK. Very complex program, very easy for garbage in garbage out situations. But we have a good number of AOE types working on it. 5. Polarization. Looks like crossed dipoles all around at the moment, shared between command radio and crosslink radio. Definite problem. Especially when you consider the L/R flip depending on look angle. So we're playing around with ideas about monopoles, dipoles, crossed dipoles, maybe one type on one bird, different type on another, etc. etc. How does that tie into attitude control. What about if we lose attitude control. What is the balance between command radio requirements with the ground and crosslink requirements. What about when the third bird deploys their drag brake and *speeds up* (one of those cool counter intuitive things about space, drag break slows them down, they drop altitude, which speeds them up relative to the other birds). Lots of tradeoffs to consider. 6. Ground networks. Currently a lot of igates are out there monitoring UHF bands for ISS (since the 2m radio failure and switch to UHF). Would be superrrrrrrr sweet if those stayed up and running to monitor the hops for this constellation. However, it is likely going to be a year or more before the first launch opportunity (we turned down a chance for this August, way to soon for us). We are still pretty early in the evolution of this project, so its possible ISS issues could be rectified (replacement installed), they switch back to 2m, and the UHF igates go bye bye. So maybe there will be a follow up request in a year or so to knock the dust off those raspberry pis and RTL-SDRs and stick em back outside. We'll see.....Fantastic idea.... 7. RFM69 is a cool little radio, but there are definitely better options for crosslink radios. We settled on this one due to the MO-76 flight heritage from the RFM22 family, the availability of interrupt outputs (6 different programmeable ones) that we could use for the time of flight measurements, as well as the ease of integration (C++ code and arduino sketches exist on github). Our first idea (before we settled on packet) was inspired heavily by the AO-73/FO-29 (and now EO-79) crosslinks, so we were looking at what could be done with linear transponders (and more traditional ranging techniques). Also back then we were considering PSK modulation formats for the digital data we needed to move around, along with heavy FEC (again AO-73 inspirations), but in the end we settled on the RFM69 (mainly once we found out 1U per bird, so the power budget got thrown out the window). For future flight opportunities though (Assuming the massive success of this one and the crazy influx of cash that is sure to ensue for follow up missions, hi hi), we'll definitely throw all the options back on the table, AFSK, FSK, PSK, linears, etc. 8. There are probably a few more comments/questions I'm forgetting to address, I apologize for that. But again many thanks to all for the very positive feedback and great recommendations. -Zach Research Associate Aerospace Systems Lab Ted & Karyn Hume Center for National Security & Technology Virginia Polytechnic Institute & State University Work Phone: 540-231-4174 Cell Phone: 540-808-6305 On 4/2/2017 9:49 PM, Greg D wrote: > Interesting proposal, with 3 universities "competing".

April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space).

Both a MSP144VDG-160 & MSP432VDG-160 which are going to be installed local in the shack. The reason being is that I have 2 switchable array's. One is my M2 2M/70cm satellite array and the other is my 2M/70cm LFA array. I generally only use one array or the other. My coax runs are short and I want to keep the pre-amp inside out of the weather. Here is my question. I can either feed 12V to each preamp and have a on-off switch to manually select the one I want, or I can feed power to them via coax that the 9100 supplies by turning on the 144 and 432 pre-amp On-Off selections in the 9100 menu. I would rather go with the 9100 supplying the pre-amp relay power instead manually supplying separate power. Here is what I need to know, in single band operation I know that each pre-amp relay would activate when on a particular band either 144 or 432. But what happens in satellite mode? Are they both active at the same time? I'm concerned about relay activations. I keep hearing about sequencers, is this required? Let me know. Steve NS3L Nazareth, Pa.

If they have the RF choke in them to feed DC up the coax (see last paragraph at http://www.advancedreceiver.com/page10.html), turn the preamp power on for both bands in the 9100 and forget about them. When you transmit, the corresponding preamp will bypass as designed. If they don't have the coax power option, feed 12v to the power connector and carry on. No need for sequencers. You will need to be careful of anything that introduces a short in the feedline between preamp and transceiver, like grounded coax switches. If you short the coax, the 9100 will sense an overload and shut off preamp power. I'm not sure how many times this will work, so I try to not let it happen with mine. I would be remiss if I didn't mention that they will work -much- better mounted at the antenna instead of inside, especially on UHF. Put them in a 2nd enclosure of some sort, like a plastic NEMA box, if you worry about weatherproofing. 73, Drew KO4MA -----Original Message----- >From: "hdskullfire2 ." >Sent: Apr 4, 2017 10:22 AM >To: amsat-bb at amsat.org >Subject: [amsat-bb] Using AR Preamps with Icom IC-9100 in Satellite mode > >I have two Advance Research Pre-amps on order.

The pre-amps are used almost exclusively on satellite. I completely manually control the pre-amps from a box I built with controls for the two pre-amps and polarity switching relays. I have separate power lines to the pre-amps. I'm with Andrew in that you should mount them at the antenna. Mine are also pretty short coax runs. There is a photo on my website that shows the NEMA box with the two pre-amps mounted just below the rotors. It's a little hard to tell that it's two pre-amps, but there really are two stacked one in front of the other.

Many months ago, in my satellite infancy, I removed the stock diplexer from my Arrow antenna and replaced it with a Comet (or Diamond?) diplexer. The commercial diplexer was built in a heavy cast cabinet and used SO-239 connectors. It was big and heavy, so I took it apart and installed it in a small Hammond diecast aluminum cabinet with BNC connectors. Much smaller and lighter. I attached it to the Arrow's boom it worked like a charm up until last weekend. Late Saturday night, while struggling in the dark to connect a cable to the diplexer I noticed that one of the female BNCs on the cabinet kept spinning as I attempted to lock the cable into place. Eureka! I opened up the diplexer cabinet later that night and found that while the center conductor connection was still solid, the ground/shield connection was shaky at best. I tightened it as best as I could and the problem went away! I want to thank you all for the many helpful responses. I read all of them carefully and followed all of the suggestions, to the extent that I could...800 km from home and with only a Swiss Army knife and needlenose pliers with me. 73 and thank you again!

There seems to have been only two passes worked from here in the last 11 years, that is about to change. Activations of rare grids should be done with enough preparation to avoid missed passes. That said, I've invited two other ops to help assure our success and maximize linear transponder passes. Our special guests will be none other than Wyatt AC0RA and Gabe NJ7H. I am more than confident in their rover skill levels and ability to maintain a functional station. They have also proven to be capable of working through unforeseen equipment troubles. Typical precautions apply. If you have linear capabilities please work us on the transponders. Our FM only friends deserve a chance at scoring a rare grid and tying up the bird helps nobody. On linear please be cognizant of your power level. I know at least two of us will be using our regular portable stations that are 5 watts max, QRO stations on the transponder will make us difficult to hear. Also, please be aware of the footprint for other ops. Nothing good comes from a left coast station getting in the middle of us trying to work the right coast. All QSOs will be uploaded to LoTW as promptly as possible and paper will be sent to shore via torpedo. Last but not least, when is it going to happen? Due to various environmental aspects, firm departure and arrival times are not set in stone. However, we can say that it will be the weekend of April 28th. When you hear K6G you will know that 02 will be on. We will have plenty of time to work many passes and none of us are afraid to work any pass no matter how shallow it may be. I may continue normal ops leading up to departure to ensure my station performs as expected. 73 and good luck, Mike Diehl AI6GS From nj1h at comcast.net Tue Apr 4 19:57:39 2017 From: nj1h at comcast.net (Bill Bordy, NJ1H) Date: Tue, 4 Apr 2017 15:57:39 -0400 Subject: [amsat-bb] AO-07 Mode B switched off at 20170404 19:28 UTC Message-ID: As has been reported before, excess power to AO-07 can cause a reset of the transponder. While monitoring AO-07 today, I heard it switch off during a QSO in process. Power should be reduced to the minimum required to hear your downlink. On the previous pass of the satellite while it was out over the Atlantic, I called CQ on SSB throughout the pass without resetting the transponder. Unfortunately, no other stations were heard on the satellite. I was using a panadapter to monitor the full pass band. 73, Bill NJ1H From david.xe3dx at gmail.com Wed Apr 5 02:23:39 2017 From: david.xe3dx at gmail.com (David Maciel (XE3DX)) Date: Wed, 05 Apr 2017 02:23:39 +0000 Subject: [amsat-bb] =?utf-8?q?Act=C3=ADvate_EK27?= Message-ID: Hi guys.

April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS. For proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Sessions go to http://www.arrl.org/hosting-an-ariss-contact.

I've been able to decode GO-32 KISS frames, but have not been able to decode other birds such as LO-74 which tend to transmit shorter bursts compared to GO-32. I'm not sure if this can be attributed to the course Doppler tuning that occurs when using HRD's Satellite Tracking program or possibly a modem parameter that needs to be set. I've used UZ7HO's Soundmodem as well as an SCS PTC-III and oddly enough, the SCS modem decodes GO-32 without a problem, but I haven't been able to do so with the Soundmodem. Any ideas?

When i first got the 847 a couplemonths ago, i copied stations on FO29 on (believe it or not) a dual band rubber duck antenna. Oh, forgot, i have diplexer on the 847 also. Back to the original, since then I have not heard one single peep. I just finished the 1700 AO7 pass, nothing heard. This was a 49 deg el pass for me in WV. Post checking the status on Amsat page shows the transponders active on the monitored birds.

Please see below for all FUNcube mission info 73s Graham G3VZV and the FUNcube team. ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Lower temperatures give higher freqs!) FUNcube-2 (aka FUNcube on UKube) The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/ EO88/Nayif-1/FUNcube-5 EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, ie the solar panels are NOT being illuminated. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. The transponder frequencies are: Uplink: 435.045 ? 435.015 MHz LSB (inverting) Downlink: 145.960-145.990 MHz USB Telemetry Tx: 145.940MHz All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

It's already been nicely digitized for you, so you just have to shovel that into your PC over, say, USB. Many USB-enabled microcontrollers have an I2S interface, which is the output of this chip.

When possible, ARISS school contacts are enhanced by crew operated HamTV. The demand for a dedicated HamTV receiver is growing. Jean-Pierre Courjaud F6DZP developed an up-to-date receiver and wrote special software for HamTV. He dubbed the receiver TuTiouner and the software. Tutioune (phonetic French transcript for ?You tune?). Components for the TuTioune receiver are for sale at the BATC shop (British Amateur Television Club). See: https://batc.org.uk/shop/dtx1 The software is available for free at: http://www.amsat-on.be/hamtv-summary/minitiouner-software/ Full details, including schematics, are provided on the HamTV home page: http://www.amsat-on.be/hamtv-summary/ Occasionally, the HamVideo transmitter must be powered down, for several reasons. The status of the transmitter is published on the amasat-on.be webpage.

There seems to have been only two passes worked from here in the last 11 years, that is about to change. Activations of rare grids should be done with enough preparation to avoid missed passes. That said, I've invited two other ops to help assure our success and maximize linear transponder passes. Our special guests will be none other than Wyatt AC0RA and Gabe NJ7H. I am more than confident in their rover skill levels and ability to maintain a functional station. They have also proven to be capable of working through unforeseen equipment troubles. Typical precautions apply. If you have linear capabilities please work us on the transponders. Our FM only friends deserve a chance at scoring a rare grid and tying up the bird helps nobody. On linear please be cognizant of your power level. I know at least two of us will be using our regular portable stations that are 5 watts max, QRO stations on the transponder will make us difficult to hear. Also, please be aware of the footprint for other ops. Nothing good comes from a left coast station getting in the middle of us trying to work the right coast. All QSOs will be uploaded to LoTW as promptly as possible and paper will be sent to shore via torpedo. Last but not least, when is it going to happen? Due to various environmental aspects, firm departure and arrival times are not set in stone. However, we can say that it will be the weekend of April 28th. When you hear K6G you will know that 02 will be on. We will have plenty of time to work many passes and none of us are afraid to work any pass no matter how shallow it may be. I may continue normal ops leading up to departure to ensure my station performs as expected.

During the European Space Weather Week, the whole Space Weather community gathers to discuss new discoveries on space weather and space climate. This is the perfect occasion to foster the evolution of the CubeSats reality from a "University tool" to a "Science tool". As usual, we have tried to organize this Symposium giving importance to the most relevant topics in the CubeSat world, from Technology Demonstrators and Scientific Missions to the Future Technologies and the Space Exploration with CubeSats. In detail, the Symposium is covering the following topics: - Novel Scientific Instruments/Sensors on CubeSats - Propulsion Subsystems - Attitude Determination and Control Subsystems - Telecommunications, Ground Stations and Ground Station Networks - Orbital Dynamics (e.g. de-orbiting and debris mitigation) - CubeSat Constellations - Scientific Missions - Technology Demonstration on CubeSats (e.g. formation flying, intersatellite link, sails, tethers, etc) - Space Exploration Missions with CubeSat (i.e. beyond Earth orbit) - Launchers and Deployers for CubeSats - Future Technologies on CubeSats - CubeSat Flight Experience and Lessons Learned Renowned speakers from NASA and ESA will give talks on their perspectives on past and future development of CubeSats. Moreover, a special session of the Symposium is dedicated to the outcome of the QB50 mission (lessons learned and first scientific results). If you are interested in contributing to this event, please submit your abstract before June 26th 2017. Registrations and abstract submission are open. For more information on the venue, registration, deadlines, abstract guidelines, sponsorship and exhibitors, please visit the symposium website www.cubesatsymposium.eu As in the previous years the Symposium is open to the entire CubeSat community, so please feel free to disseminate this information further.

ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS. For proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Sessions go to http://www.arrl.org/hosting-an-ariss-contact. Please direct any questions to ariss at arrl.org.

Located in Normandy, in the heart of the regional natural park of le Perche, this village of approximately two thousand inhabitants sits on a hill dominating the Perche area. Roger Martin du Gard was constructed in the 1970s and was totally rebuilt on the same location in 1994. It got its name from Literature Nobel Prize, Roger Martin du Gard, a writer who lived the last part of his life nearby, in Le Ch?teau du Tertre. The number of students has been stable for the past four years, with about three hundred children in twelve different classes (3 in each level, from grades 7 through 10). It welcomes students from age 11 to 15. This school project, ARISS, aims at having the students succeed in their different education paths. The ARISS project is the one opportunity to show the students that being in a rural area does not limit their possibilities and their capacities to do things. It is a way to help them find a possible future in such an important field. Complementing their physics program, it also offers a magical moment to all the students in the school, while showing that working serves a real motivation. * A direct contact via W6SRJ with students at Brook Haven School in Sebastipol, CA is being planned for the week of April 17. More details will follow. ********************************************************************** ARISS is always glad to receive listener reports for the above contacts.

After that, press button on the top of this tab - the first from the right (Earth with the thunder). Update process should start. At the end click OK. And close setup window (OK). b) Now check the date of update. Select some satellite (eg. the ISS). Then select tab: "Sat/Orbit info" and check line with Epoch (UTC). There should be date from today or yesterday eg. for ISS from today is (right now): 2017-04-08 20:39:01 c) if the update is wrong, you should start Orbitron with administrator permission, or select another location of the TLE data (in the user folder).

Message-ID: Hello all, I'm looking for a mobile radio that, among other things, will work well for FM satellites. I'm familiar with the Kenwood and Yaesu products, but I'm interested in the ICOM IC-2730A. I've found it difficult to get definitive opinions on these points: 1. Does it support true full-duplex operation? (It supports "simultaneous receive", but is it full-duplex?) 2. Can you program memory locations with odd-splits? (It looks to me like it doesn't.) 3. Can it be controlled by SatPC32? (It does support ICOM's CI-V protocol, so I think a basic level of control might be possible.) As an aside, if I don't end up with the IC-2730A, I will likely get the Yaesu FT-8900R - a much older design - but for sure does full-duplex and odd-splits (although no control protocol). Thanks & 73, Ken VA7KBM From amsat-bb at wd9ewk.net Mon Apr 10 22:33:27 2017 From: amsat-bb at wd9ewk.net (Patrick STODDARD (WD9EWK/VA7EWK)) Date: Mon, 10 Apr 2017 15:33:27 -0700 Subject: [amsat-bb] IC-2730A: Full-Duplex, Odd-Splits, SatPC32? In-Reply-To: References: Message-ID: ?Ken, I have had an IC-2730A for almost a year. Nice radio for FM satellite work. Answering your questions... 1. Yes, it supports true full-duplex operation. Put the uplink and downlink in the two VFOs, and adjust the squelch and volume so you only hear the downlink VFO. Set PL tones as needed in the uplink VFO, and - if not using memory channels - confirm the tuning step is 5 kHz. You can also use narrow FM, should you decide to use that in either VFO (or both VFOs) when working AO-85. 2. No, you cannot program memory channels to handle odd splits where the transmit and receive frequencies are in different bands. You can program a receive frequency and the size/direction of an offset for a memory, but this requires both frequencies to fall within the same band. This is, unfortunately, a common "feature" with Icom radios made in at least the past 15 to 20 years. With access to both VFOs, including the separate knobs for each VFO, you don't have to flip-flop which VFO is the "main" VFO, or use function keys to go between the VFOs whenever you want to change something. 3. Other than a quick scan through the PDF manual, I have never looked into any CI-V functionality with this radio. I see CI-V settings listed for the radio, but that's probably as far as I will go with that. Manually adjusting the VFOs isn't difficult with this radio, given the separate controls for each VFO. I don't see any accessories listed that relate to CI-V in the manual; just the cloning cables and extension cables for the faceplate and microphone. The IC-2730A does not include a DATA port for 9600bps data. I think Icom was trying to keep this radio as a lower-cost 2m/70cm FM mobile, yet offering that and other options in the more expensive D-Star capable mobiles. Other than how Icom chose not to include a mobile mounting bracket and the kit to mount the faceplate directly to the radio "box", I like this radio. Good luck, and 73!

In-Reply-To: References: Message-ID: <8d43ddc7-25ee-2dd3-16c4-539290b23ccc@amsat.org> I have had the best luck, and most experience with, Kenwood dual-banders on satellites. I've been using the TM-D700 and TM-D710 series on all the available FM satellites for the past six years with great success. With TM-D700's being available at bargain prices sometimes, it is hard to spend triple for a new TM-D710 (although they're quite nice.) Almost any manufacturer's rig I have tried do not support cross-band/VFO "split" memory channels for full duplex. It's no problem because you can open a separate memory on one VFO for uplink and another memory channel on the other VFO for downlink. 73 Clayton W5PFG On 4/10/2017 15:32, Ken M wrote: > Hello all, > > I'm looking for a mobile radio that, among other things, will work well > for FM satellites.

The move is due to down-sizing, necessitated by aging. As some may know, I operated from a second floor room in the northeast corner of our Vermont home, using an Arrow antenna indoors. It worked remarkably well, especially on the linear transponders in directions from north to south. West was a challenge due to the building, but Europe was a sweet spot. It was a great run, I now have over 1500 grids confirmed. Thanks to everyone on the birds, especially the rovers! Unfortunately, my new location in a condo, appears to be not so conducive for working the birds. I may try some occasional outdoor ops from portable locations this summer, but will miss the regular comradery of our small fraternity, it has been a lot of fun! Enjoy the hobby and be good to each other! 73 and gud DX!

April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS.

The event is scheduled to begin at approximately 15:20 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between FX0ISS and F6KCO. The contact should be audible over France and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in French. Roger Martin du Gard is a middle school in Bell?me, France. Located in Normandy, in the heart of the regional natural park of le Perche, this village of approximately two thousand inhabitants sits on a hill dominating the Perche area. Roger Martin du Gard was constructed in the 1970s and was totally rebuilt on the same location in 1994. It got its name from Literature Nobel Prize, Roger Martin du Gard, a writer who lived the last part of his life nearby, in Le Ch?teau du Tertre. The number of students has been stable for the past four years, with about three hundred children in twelve different classes (3 in each level, from grades 7 through 10). It welcomes students from age 11 to 15. This school project, ARISS, aims at having the students succeed in their different education paths. The ARISS project is the one opportunity to show the students that being in a rural area does not limit their possibilities and their capacities to do things. It is a way to help them find a possible future in such an important field. Complementing their physics program, it also offers a magical moment to all the students in the school, while showing that working serves a real motivation. Participants will ask as many of the following questions as time allows: 1. Qu'est-ce-qui vous a donn? envie de devenir astronaute? 2. Quel r?gime alimentaire devez-vous adopter dans l'espace? 3. Quel fuseau horaire suivez-vous dans l'espace? 4. Dans les exp?riences de culture que vous menez, o? en ?tes-vous? 5. Avez-vous rencontr? des d?bris spatiaux durant votre voyage jusqu'? l'ISS? 6.

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

You did amazingly wellwith an indoor antenna! No matter where I went on GridExpeditions, you would usually pop up with a great signaland never trying to talk over someone else. You are a greatexample of a courteous operator and a gentleman. It was sonice to have been able to meet up with you as I passed throughBurlington on one of my trips.

The move is due to down-sizing, necessitated by aging. As some may know, I operated from a second floor room in the northeast corner of our Vermont home, using an Arrow antenna indoors. It worked remarkably well, especially on the linear transponders in directions from north to south. West was a challenge due to the building, but Europe was a sweet spot. It was a great run, I now have over 1500 grids confirmed. Thanks to everyone on the birds, especially the rovers! Unfortunately, my new location in a condo, appears to be not so conducive for working the birds. I may try some occasional outdoor ops from portable locations this summer, but will miss the regular comradery of our small fraternity, it has been a lot of fun! Enjoy the hobby and be good to each other! 73 and gud DX! Nick, KB1RVT Sent from my iPad _______________________________________________ Sent via AMSAT-BB at amsat.org.

I used an Arrow antenna, standing outside with one Yaesu FT-60 HT running 5 watts on 1/2 duplex. It was on AO-51. What a satellite. It, along with AO-27 were some great times on FM. I think we worked 40 times over the years. I sure hope we get to work more in the future.

I apologize if this has been discussed before, but I couldn't find answers online so I was hoping you all could help me out. First, it seems easiest to me to build an antenna system that can either switch between vertical and horizontal linear polarizations, or between right hand and left hand circular polarization. Which would be more useful? And is it worth the extra effort to build an antenna system that can switch between all four polarizations? Also, I've been looking at the different ways of achieving circular polarization. I like the idea of using mechanical 1/4 wave separation between the two yagis so I don't have to cut phasing lines. Would it be possible to switch polarizations by putting a relay at the feedpoint of one of the yagis and switching which side of the driven element the center conductor and shield of the coax goes to? I've never seen this done before, but it seems to me it would work. Any thoughts?

I apologize if this has been discussed before, but I couldn't find answers online so I was hoping you all could help me out. First, it seems easiest to me to build an antenna system that can either switch between vertical and horizontal linear polarizations, or between right hand and left hand circular polarization. Which would be more useful? And is it worth the extra effort to build an antenna system that can switch between all four polarizations? Also, I've been looking at the different ways of achieving circular polarization. I like the idea of using mechanical 1/4 wave separation between the two yagis so I don't have to cut phasing lines. Would it be possible to switch polarizations by putting a relay at the feedpoint of one of the yagis and switching which side of the driven element the center conductor and shield of the coax goes to? I've never seen this done before, but it seems to me it would work. Any thoughts? Thanks and 73, Brady AC0XR _______________________________________________ Sent via AMSAT-BB at amsat.org.

I have no personal experience fabricating these, but we use them in the VT Ground station to switch between LHCP/RHCP. M2 Antennas documentation warns of a slight VSWR increase with this technique, but so far (couple years now) they have performed great for us. second penny) While you might not have to cut phasing lines with the 1/4 wave offset technique, you will likely need to cut 1/4 wave impedance transformation lines. If your two feedpoints are 50 ohms each, then a 1/4 wave transformer of 75 coax will be needed (transforming to 100 Ohms) so that when they are placed in parallel (via a splitter/combiner) you present 50 ohms to the feedline/radio. This link has a lot of good info on this: http://www.qsl.net/sv1bsx/antenna-pol/polarization.html third penny) There is a great section in the ARRL Antenna Book (I think in the Antennas for Space Communications chapter) about using a coax relay and a pair of 50 ohm feedpoint yagis to achieve circular polarization. The coax used in that example is both for phasing and impedance transformation in one, though requires 100 ohm (or close to that) coax (which last time I checked was available at the RF connection, who can also fabricate properly phase calibrated cables for you). Also the relay in that example was not at the feedpoint of the antenna. So it does exactly the opposite of what you are trying to do (antennas are not offset, and you need phasing/impedance transformation lines) but in my experience I found it easier than trying to crack open a (potentially expensive) coax relay and integrate it into a feedpoint (I left that to the pros at M2 Antennas). Good Luck! 73s, Zach, KJ4QLP Research Associate Aerospace Systems Lab Ted & Karyn Hume Center for National Security & Technology Virginia Polytechnic Institute & State University Work Phone: 540-231-4174 Cell Phone: 540-808-6305 On 4/12/2017 6:51 PM, Richard Tejera wrote: > Brady, > > Domenici, I8cvs SK had published a pair of articles on making a switching relay between vertical, Horizontal, LHCP & RHCP. he sent me PDF's, which are in my to do someday folder. > > Contact me off list (email is good on QRZ), and I will send them to you.

Early this weekend partly because of the Easter Holiday, and party due to Ground Station Availability. The plan is to revert back to normal Educational Mode after the Holiday either on Mon pm, and Tue am, UTC. Enjoy the transponder, and happy holidays! 73s Jim G3WGM and the FUNcube Team ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Low temperatures give higher freqs!) FUNcube-2 aka FUNcube on UKube The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/EO88 Nayif-1 FUNcube-5EO88 is presently operating in autonomous mode. The transponder isoperational when the satellite is in eclipse, ie the solar panels are NOTbeing illuminated.When the transponder is switched off, the telemetry beacon is on full power,when the transponder is on the beacon it is on low power.The transponder frequencies are:Uplink: 435.045 ? 435.015 MHz LSB (inverting)Downlink: 145.960-145.990 MHz USBTelemetry Tx: 145.940MHzAll FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

It is very helpful, and I do appreciate it. The SV1BSX site is great, and the visualizations really helped me understand how circular polarization works. Thanks especially Zach for letting me know about M2 Antennas using the relay at the feedpoint. That's also a good point about having to cut impedance transformation lines, even if I did use a physical 1/4 wave offset. I may build something to switch between both linear and circular polarizations. I'm hoping to build the antennas in time for Field Day, so I can do a satellite demo for my club. Thanks again, and I hope to be able to work you on the sats soon! 73, Brady AC0XR From e.krome at comcast.net Thu Apr 13 23:58:33 2017 From: e.krome at comcast.net (Ed Krome) Date: Thu, 13 Apr 2017 19:58:33 -0400 Subject: [amsat-bb] AMSAT dinner?

If I am able to do that, I'll probably operate under my WD9EWK call from these locations. I'll try to post to the AMSAT-BB plans for the on-air demonstrations, and those will definitely be available on my @WD9EWK Twitter feed - visible in a web browser at: http://twitter.com/WD9EWK If you hear me on the air from these meetings, please give me a call and be a part of the demonstration. Any QSOs made as WD9EWK at these radio club meetings will be uploaded to Logbook of the World. QSL cards are available on request, without first sending me a QSL card or SASE; please e-mail me with the QSO details. These presentations, along with other presentations and hamfests with an AMSAT presence, are listed on the AMSAT web site at: http://www.amsat.org/?page_id=218 73!

April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS. For proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Sessions go to http://www.arrl.org/hosting-an-ariss-contact.

A few months back, the ARISS Team did the foot work and paperwork to launch the final copy of the Ericsson VHF handheld radio to the ISS. This work was began in October after the unit onboard the ISS failed. ARISS has been using the Ericssons for 16 years. In the last days of February, the launch vehicle, SpaceX 10's Dragon, flew to the ISS. Then the ISS crew had the odious job of unloading and unpacking 5,500 pounds of cargo along with the Ericsson HT. ARISS got word this morning that we now have VHF capability back in the Columbus module. Followers of ISS Fan Club have already posted that they've heard and used packet, and are thrilled. In 2015, ARISS began its first fundraising campaigns. It relies on NASA, ARRL, AMSAT and individual donors, along with ARISS volunteers to pay the day-to-day operations expenses and everything related to the hardware, testing, and certification. Donors can go to www.amsat.org and www.ariss.org to support the program.

April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS.

From amsat-bb at wd9ewk.net Sat Apr 15 23:50:52 2017 From: amsat-bb at wd9ewk.net (Patrick STODDARD (WD9EWK/VA7EWK)) Date: Sat, 15 Apr 2017 23:50:52 +0000 Subject: [amsat-bb] Thoughts on ISS packet switch back to 145.825 MHz (long) Message-ID: Hi! Earlier today, I tweeted a quick comment about what I saw on the ISS 145.825 MHz digipeater just after 1900 UTC this afternoon. Since tweets are limited in length, I'm posting a longer message here... In the past few weeks, once word got out that a replacement for the failed Ericsson VHF HT on the ISS was being sent up to the station, many were anxiously looking forward to seeing the ISS digipeater move from 437.550 MHz back to 145.825 MHz, where it had been until the old radio's failure in mid-October 2016. I understood that many would welcome this change, but I was not jumping up and down with excitement. Unfortunately, after seeing the activity on the ISS digipeater in the past day or so since the replacement VHF radio was put on 145.825 MHz, my worries have been confirmed. For many, the move to 437.550 MHz meant many stations that could easily work 145.825 MHz would have to change. Whether it was a different antenna for the 70cm band or dealing with Doppler with the 437.550 MHz frequency, almost all of the unattended stations that had been present on the 145.825 MHz frequency were gone. If you wanted to use the ISS digipeater to work other stations, this was a great opportunity. Many stations using APRS-ready HTs and mobile transceivers were showing up, using a group of memory channels to compensate for Doppler, and were making contacts. Some fixed stations, including those already capable of satellite operating, were also showing up. Even on the busier passes, the 437.550 MHz always seemed to be clear of the clutter from the unattended stations that previously inhabited 145.825 MHz. Fast forward to yesterday (Friday, 14 April). The ISS digipeater switched to 145.825 MHz in time for afternoon/evening passes over Europe (around 1330-1400 UTC). Lots of stations showed up, based on looking at the ariss.net web site. The same thing started to happen here in North America, later in the day. The passes I worked last night were not bad, but there were more stations on one pass that went over much of the continental USA than I'd typically see on 437.550 MHz. By midday today (1900 UTC), it seemed like many more stations were on the frequency. I saw 11 other call signs on a pass just after that time this afternoon. At best, there may have been 4 or 5 other operators at their keyboards or keypads, looking to make contacts. The others were just squawking away, not answering APRS messages sent to them. By the time the ISS footprint was reaching the east coast, the frequency was congested. Lots of position beacons were coming through, but not much of anything else. This is not new; Clayton W5PFG wrote about this about a year ago, here on the AMSAT-BB list: http://amsat.org/pipermail/amsat-bb/2016-April/058200.html For the two passes I worked this afternoon, around 1900 and 2035 UTC, I made two QSOs on the earlier pass, and one on the later pass. A shame, considering there were so many other call signs on the earlier pass, and even some rare spots - stations in DM44 in northern Arizona and CM86 in Santa Cruz CA were seen. It is interesting that hams want to have their stations squawk on 145.825 MHz when nobody is at the keyboard. It could be doing it 24/7, no matter if the ISS is in view or not. Would anyone think of setting up their satellite station to automatically transmit their call sign and location every 15/30/60 seconds to SO-50, unattended? I think not! That could be a violation of the regulations, and would definitely be poor form by that operator. Bob Bruninga WB4APR has a couple of documents with recommendations for beacon intervals when working the ISS digipeater. One mentioned a 5-minute interval for unattended stations: http://www.aprs.org/iss-aprs/iss-tx.txt Another document recommends that unattended stations should be in "receive ONLY mode." (emphasis is Bob's): http://www.aprs.org/iss-aprs/utiquet.txt I agree with the latter. If your station is unattended, why have it transmit at all?! It may be different for less-populated parts of the world, where gateway stations may transmit and then receive their beacons from the ISS, which will show up on ariss.net and other sites. For Europe, and definitely North America, the gateways really don't need to transmit if they are unattended. There should be activity on most passes, maybe even late into the night, to know 145.825 MHz on the ISS is up and running. Please don't misunderstand me... I think it is great for hams to set up gateway stations listening on 145.825 MHz for the space-borne APRS activity (ISS, NO-84, even NO-44 when it gets enough power to transmit complete packets). But these stations, like other stations that aren't operating as gateways yet transmit automatically, shouldn't contribute to the congestion on the frequency. I know I am in the minority on the ISS digipeater moving back to 145.825 MHz. Between the unattended stations clogging up the frequency and some local interference I hear on 145.825 MHz around my house, having the ISS on 437.550 MHz was fun! I worked it from home, and on some of my road trips in the past 5+ months. Even for some of my last NPOTA activations at the end of 2016. I'll continue to work the ISS digipeater, almost exclusively with my APRS-ready HTs (TH-D72A, or TH-D74A), looking to make QSOs by exchanging APRS messages with other stations. If you can work packet from your station, and we are in the same footprints, I hope to hear you (and see you on my screen) soon. Like W5PFG mentioned a year ago, let's get more stations on 145.825 MHz making QSOs... 73!

Message-ID: The RARSfest satellite demos today were a success, despite some difficulties. In all we made 17 contacts across one SO-50 pass and one FO-29 pass. You can see a few pictures of the demos here: http://imgur.com/a/uMOF4 I had trouble getting into SO-50, and Tucker, W4FS, had trouble hearing FO-29. After reviewing a video I made of the SO-50 pass, I realized I wasn't aiming the antenna in the right direction for the first half of the pass. I had a hard time tracking it as the location we chose which was the easiest for attendees to find was also right next to the building the hamfest was in, and SO-50 rose right behind it. By the time I heard the bird around 20 or 30 degrees elevation, I wasn't aiming quite right, so every time I tried to get in I got very intermittent audio at best. After one complete transmission, Jeff, WB8RJY, came back to me and said hi to the hamfest and everyone clapped. Unfortunately I wasn't able to complete the QSO. At max elevation I knew exactly where to aim and called him back and completed the QSO. Towards the end of the pass when the bird was further north and less people were in its footprint I made a string of contacts adding up to eight in total. As for FO-29, Tucker was getting S9 noise during the first half of the pass and could barely hear any signals. I experienced the same interference yesterday when I did some practice passes. It's something local we can't control. It was so bad Tucker actually turned off the radio halfway into the pass and apologized to everyone that he wasn't going to be able to complete the demo. Not long after this he noticed a text message from a friend listening to him on the downlink saying he sounded fine. So he turned the radio back on and this time there was no noise because all we heard were very clear voices. After he found himself on the downlink and made one CQ, Clayton, W5PFG, came right back to him. And the crowd cheered when Clayton referenced the hamfest and said he was from Texas. After that Tucker had a mini pileup and made eight more contacts adding up to nine in total. It looks like I had a crowd in the high 20s and Tucker had a larger crowd in the low 30s. I was pleasantly surprised we were able to get such a good turnout considering this was added to the hamfest at the last minute. Thanks to all of the operators who worked us! And to anyone that called us who we couldn't get back to, like Paul, N8HM, thanks for trying and sorry we couldn't make contact.

It is much appreciated. I am too looking once in a while for an ISS contact. On the other hand, I have realized that many stations are actually on the keyboard and they answer, but I don't decode it on my system and they might not either. I see it later on the web. In addition, folks are not that quick in response also and trying to type an answer and get a packet out especially on a less elaborate station is not always easy. Yes, I am using UISS with pre-recorded answers and a quick mouse click but I still need a few tries to sometimes see or hear my own packet repeated. So, bottom line for me, be happy for the few contacts and help others along :-) 73, Stefan, VE4NSA On Sat, Apr 15, 2017 at 6:50 PM, Patrick STODDARD (WD9EWK/VA7EWK) < amsat-bb at wd9ewk.net> wrote: > Hi! > > Earlier today, I tweeted a quick comment about what I saw on > the ISS 145.825 MHz digipeater just after 1900 UTC this > afternoon.

ARISS did the foot work and paperwork a few months ago to launch the last back-up Ericsson VHF handheld radio to the ISS. This work was begun in October after the failure of the Ericsson unit that had been used on the ISS. The Ericssons have been operating on the ARISS for 16 years. In the last days of February, the SpaceX 10 launch vehicle, Dragon, flew to the ISS with the HT onboard. After the docking, ISS crew members had the odious job of unloading and unpacking 5,500 pounds of cargo, including the Ericsson HT. ARISS got word Friday morning that we now have VHF capability back in the Columbus module. Followers of ISS Fan Club have already posted that they've heard and used VHF packet, and are thrilled and happy to have it again! In 2015, ARISS began its first fundraising campaigns. ARISS relies on NASA, ARRL, AMSAT and many fine individual donors, along with ARISS volunteers, to maintain the day-to-day operations and cover those expenses along with all costs and work related to the hardware, and building a new radio system, including the expensive space certification tests. Donors can go to www.amsat.org and www.ariss.org to support the program that excites hams and young people and educators who are inspired by amateur radio on the ISS. 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.

It was the efforts of those volunteers that made the 2016 Dayton Hamvention a success for AMSAT. The interaction with AMSAT members, satellite operators, designers, and builders makes the whole experience a lot of fun. The 2016 Hamvention is May 19-21 in a new venue: the Greene County Fairgrounds in Xenia, Ohio. Would you consider helping AMSAT at the Hamvention this year? 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.

Through the Melbourne Space Program (MSP) affiliated with the University of Melbourne, all is moving ahead for a hand-over of the nano-satellite in November and a launch as early as January 2018. Funding comes from the University of Melbourne, while the Melbourne Space Program is an organisation that holds the licensing, and other matters related to the launch. In a media release, the MSP revealed that plans are well under way with rideshare provider SpaceFlight with a contract signed for a November hand-off and its launch as early as January 2018. It has involved a group of ambitious students, seeking to understand and help redefine the Australian space sector through innovation in education, economics and policy, as well as engineering. Australia is the only Organisation for Economic Cooperation and Development (OECD) nation without a space agency. In 1966, University of Melbourne students built Australia's first satellite that was launched in 1970 as Australis Oscar 5 to be tracked by 200 radio amateurs in 27 different countries. The Melbourne Space Program has about 70 active members who are students ranging from 1st year university to masters level and post- graduate. The key objectives include being the first students to launch an Australian nano-satellite, create education, research in space, collaborate with academia and industry, and promote gender parity in the STEM (science, technology, engineering and mathematics) and Arts disciplines. Work was continuing to launch Australia's first nano-satellite and more news is expected in coming months. (Fred Swainston VK3DAC/VK4FE, WIA STEM Coordinator) Aussies tracking satellite Students of the FH Aachen University of Applied Sciences in Germany will launch the COMPASS 2 cube-sat in May and are at looking for a possible ground station partner in Australia. WIA Director Fred Swainston VK3DAC/VK4FE, WIA STEM Coordinator says the International Space Station Crew Fund Scholarship winner for 2017, Ian Benecken has asked the Wireless Institute of Australia for help to track it. COMPASS 2 is to be launched from a Polar Satellite Launch Vehicle by the Indian Space Research Organisation carrying other commercial satellites. >From a polar 600 kilometre high orbit the cube-sat will beacon once a minute the callsign of ON04DL (ON zero four DL) on 437.300 MHz. The unique location of Australia makes it ideal for partner ground stations, and already it has piqued an interest from the ARISS telebridge centres on VK4, VK5 and VK6. Soon to be published is software that anyone can use to decode the beacon signal and the launch is likely to be on the 1st or 2nd week of May.

I also look online after the passes, hoping to see gateways picking up the activity. Looks like some of the gateways either need to be turned on again, or switched back to 145.825 MHz. Seems like there are a lot of stations using UISS, which makes the use of APRS messages an easy thing. Several of the calls I saw on the radio today were the same calls that never responded to APRS messages in the past. More often than not, if the station is using an HT, or maybe a mobile radio (as identified on the screen when I see details on that station on my screen), those are the stations I have the best chance at making a QSO. Maybe some of these stations won't stay on 145.825 MHz, after the novelty of the ISS digipeater coming back to 2m wears off. If there are operators at those keyboards, hopefully they will answer the APRS messages they receive from me and others, and try to contact stations they see/hear on these passes.

I'm also using UISS with the fields pre-loaded for quick, standardized answers given the short time of the pass. While it is quite convenient to load up some software for soundmodem and UISS vs. all the hardware cable connections to a standalone TNC - the shortcoming with the software approach is that you'll only decode and display packets that are 100% correct, with no single bit error, checksum matches perfectly. So our stations are often copying a good-sounding downlink signal but it just takes a single bit error and we're not seeing the other station's reply on the screen ... or they're missing our reply. For this reason I'm thinking of going back to my MFJ-1270C TNC when I have some time to wire it back up. In the TNC you can issue the PASSALL = ON command and you'll see all packets, even the incomplete or bad bit messages. In the past I saw enough of most messages that I could understand what was received. No unattended beacons at this shack - but the preloaded messages I have within UISS are usually the same on many passes. -- 73 de JoAnne K9JKM k9jkm at amsat.org From wageners at gmail.com Sun Apr 16 02:54:35 2017 From: wageners at gmail.com (Stefan Wagener) Date: Sat, 15 Apr 2017 21:54:35 -0500 Subject: [amsat-bb] Thoughts on ISS packet switch back to 145.825 MHz (long) In-Reply-To: References: Message-ID: Thanks JoAnne, Point well made!

I have lightly tested it, and it works fine with UISS. It also can give a lot of information about the RX signal. It is a bit more work to set up compared with Soundmodem because it uses a configuration file, but you also get more fine tuning. 73s, Alan WA4SCA <-----Original Message----- ...many stations are actually on the keyboard and they < > answer, but I don't decode it on my system and they might not < > either ... using UISS ... < References: Message-ID: <15b74f574d8.2808.7f4d2737b6a69b496aabc539d02dbffb@gmail.com> JoAnne, What software would you run with your hardware TNC ?

It came on 5.25 disk but I have a copy of it on an old computer hard drive ... good thing I'm an electronics hoarder. I still haven't tossed out PC's from the 1990's :-) The window MFJCOM software runs in is the command line interface. It pretty much looks like the window you get with the windows 'Run' command. Plain ascii, not much help for commands, no mouse, etc. When MFJCOM comes up in the usual TNC 'cmd:' mode you can send the setup and operating commands to the TNC. Once setup in the cmd; mode you issue a 'CONVERS' command to enter the UI mode. A ctrl-c gets you out of CONVERS and back to cmd; My article in the AMSAT Journal has a table showing the top dozen or so TNC commands useful for configuring a hardware TNC for operation with ARISS packet. I believe there would be lots of terminal emulator programs out there that get the job done. Running in this basic mode I'm talking directly to the TNC hardware. What the TNC receives is what I'd see directly in the terminal emulator window. I still have the hardware TNC project on my to-do list. Before I go so far as trying to bring up a 20 year old PC box I think I'll take Alan's advice and try Direwolf. Alan mentioned that Direwolf has some of the commands I've been missing via UISS - like PASSALL and ways to display some of the additional protocol. Now that I think about it, I have an old laptop with dual-boot linux and windows on it which also has a 'real' RS-232 port on it - I could see how linux based terminal emulators work too.

I have an olde DSP2232 TNC that I used in the 'old' days when I was the South East area Satgate. It has full duplex packet capabilities among others. Been using it lately for QRP (5 watts) RTTY. The programs I have are: HyperterminalPrivatge, K95g (Kermit), Putty, Realterm, TeraTerm, and Termite V3.2. Each has their own advantages. I use TeraTerm the most. I like that it can have cut and paste data inserted i n the window. I believe it also allows you to send a file as well. Most of them are a matter of taste. K95 has a lot of built-ins but a bit harder to use. Reid, W4UPD On 4/16/2017 9:46 AM, JoAnne K9JKM wrote: > Hi Kevin, > > > What software would you run with your hardware TNC ?

Bob, WB4APR -----Original Message----- From: AMSAT-BB [mailto:amsat-bb-bounces at amsat.org] On Behalf Of Patrick STODDARD (WD9EWK/VA7EWK) Sent: Saturday, April 15, 2017 7:51 PM To: amsat-bb at amsat.org Subject: [amsat-bb] Thoughts on ISS packet switch back to 145.825 MHz (long) Hi! Earlier today, I tweeted a quick comment about what I saw on the ISS 145.825 MHz digipeater just after 1900 UTC this afternoon. Since tweets are limited in length, I'm posting a longer message here... In the past few weeks, once word got out that a replacement for the failed Ericsson VHF HT on the ISS was being sent up to the station, many were anxiously looking forward to seeing the ISS digipeater move from 437.550 MHz back to 145.825 MHz, where it had been until the old radio's failure in mid-October 2016. I understood that many would welcome this change, but I was not jumping up and down with excitement. Unfortunately, after seeing the activity on the ISS digipeater in the past day or so since the replacement VHF radio was put on 145.825 MHz, my worries have been confirmed. For many, the move to 437.550 MHz meant many stations that could easily work 145.825 MHz would have to change. Whether it was a different antenna for the 70cm band or dealing with Doppler with the 437.550 MHz frequency, almost all of the unattended stations that had been present on the 145.825 MHz frequency were gone. If you wanted to use the ISS digipeater to work other stations, this was a great opportunity. Many stations using APRS-ready HTs and mobile transceivers were showing up, using a group of memory channels to compensate for Doppler, and were making contacts. Some fixed stations, including those already capable of satellite operating, were also showing up. Even on the busier passes, the 437.550 MHz always seemed to be clear of the clutter from the unattended stations that previously inhabited 145.825 MHz. Fast forward to yesterday (Friday, 14 April). The ISS digipeater switched to 145.825 MHz in time for afternoon/evening passes over Europe (around 1330-1400 UTC). Lots of stations showed up, based on looking at the ariss.net web site. The same thing started to happen here in North America, later in the day. The passes I worked last night were not bad, but there were more stations on one pass that went over much of the continental USA than I'd typically see on 437.550 MHz. By midday today (1900 UTC), it seemed like many more stations were on the frequency. I saw 11 other call signs on a pass just after that time this afternoon. At best, there may have been 4 or 5 other operators at their keyboards or keypads, looking to make contacts. The others were just squawking away, not answering APRS messages sent to them. By the time the ISS footprint was reaching the east coast, the frequency was congested. Lots of position beacons were coming through, but not much of anything else. This is not new; Clayton W5PFG wrote about this about a year ago, here on the AMSAT-BB list: http://amsat.org/pipermail/amsat-bb/2016-April/058200.html For the two passes I worked this afternoon, around 1900 and 2035 UTC, I made two QSOs on the earlier pass, and one on the later pass. A shame, considering there were so many other call signs on the earlier pass, and even some rare spots - stations in DM44 in northern Arizona and CM86 in Santa Cruz CA were seen. It is interesting that hams want to have their stations squawk on 145.825 MHz when nobody is at the keyboard. It could be doing it 24/7, no matter if the ISS is in view or not. Would anyone think of setting up their satellite station to automatically transmit their call sign and location every 15/30/60 seconds to SO-50, unattended? I think not! That could be a violation of the regulations, and would definitely be poor form by that operator. Bob Bruninga WB4APR has a couple of documents with recommendations for beacon intervals when working the ISS digipeater. One mentioned a 5-minute interval for unattended stations: http://www.aprs.org/iss-aprs/iss-tx.txt Another document recommends that unattended stations should be in "receive ONLY mode." (emphasis is Bob's): http://www.aprs.org/iss-aprs/utiquet.txt I agree with the latter. If your station is unattended, why have it transmit at all?! It may be different for less-populated parts of the world, where gateway stations may transmit and then receive their beacons from the ISS, which will show up on ariss.net and other sites. For Europe, and definitely North America, the gateways really don't need to transmit if they are unattended. There should be activity on most passes, maybe even late into the night, to know 145.825 MHz on the ISS is up and running. Please don't misunderstand me... I think it is great for hams to set up gateway stations listening on 145.825 MHz for the space-borne APRS activity (ISS, NO-84, even NO-44 when it gets enough power to transmit complete packets). But these stations, like other stations that aren't operating as gateways yet transmit automatically, shouldn't contribute to the congestion on the frequency. I know I am in the minority on the ISS digipeater moving back to 145.825 MHz. Between the unattended stations clogging up the frequency and some local interference I hear on 145.825 MHz around my house, having the ISS on 437.550 MHz was fun! I worked it from home, and on some of my road trips in the past 5+ months. Even for some of my last NPOTA activations at the end of 2016. I'll continue to work the ISS digipeater, almost exclusively with my APRS-ready HTs (TH-D72A, or TH-D74A), looking to make QSOs by exchanging APRS messages with other stations. If you can work packet from your station, and we are in the same footprints, I hope to hear you (and see you on my screen) soon. Like W5PFG mentioned a year ago, let's get more stations on 145.825 MHz making QSOs... 73!

I AGREE 100 %.. When it was on 437.550 stations had a chance to make some contacts. Now that it is back on 145.825 the satellite is saturated with stations almost eliminating the possibility of making a good contact through the digipeater. Today is Easter Sunday and on the 1815 UTC pass through middle America it was like working a pileup on 20 meters. Hopefully over time , we will see a reduction in Activity on the ISS packet system and more trying to work NO84 and NO44 .

The amateur radio equipment on the ISS is an experiment! Sometimes it works and sometimes it doesn't. Based on your location, equipment and ISS position you will* NOT* decode every packet, and yes that includes your own packets. So folks will be trying again and that's okay. *They don't become a source of QRM* on the ISS since the ISS will only re-transmit if its a good packet. They are exercising their license privileges to work through the ISS and for many having that first digipeat after many tries is their success story and we welcome that. 73, Stefan, VE4NSA On Sun, Apr 16, 2017 at 1:43 PM, Gabriel Zeifman wrote: > I think the golden rule of working all sats applies to ISS as well: if you > can't hear (or decode), don't transmit!

The point he's trying to make is that many stations just keep on transmitting when they can't hear anything. We can use that amateur radio on ISS as an experiment as an excuse but that doesn't really fly. APRS is beyond an experiment as it is a well established form of using APRS via satellite, nothing new here. Furthermore, what is the point of trying repeatedly to transmit if you can't decode? It is the golden rule for a reason and it applies everywhere, satellite or terrestrial. If you can't hear it you can't work it, bottom line. Until you can decode packets you're just creating QRM. 73, Mike Diehl AI6GS > On Apr 16, 2017, at 2:46 PM, Stefan Wagener wrote: > > Hi Gabe, > > With all respect I very much disagree.

Based on your setup, TNC, software etc you will NOT be able to decode every single packet and based on your setup and the ISS position the ISS digipeater will not re-transmit. It's the nature of the beast. No, you are not creating QRM if the ISS does not repeat your packet. Listen to the path of the ISS and you will hear that 50% of the time the radio is silent. It does not TX since there are no valid packets. Where is the QRM? There is none other than in you local environment where nobody cares. Don't discourage those that are trying to make it work. If you want a case, point out the stations and callsigns that create QRM and are not listenting/responding! Just check out the last pass over the US. You will find 10 stations, that's a station a minute with room to spare. This is NOT SO-50! 73, Stefan, VE4NSA On Sun, Apr 16, 2017 at 5:05 PM, Mike Diehl wrote: > Stefan, > > I think you're taking Gabe's comment too literal.

I think you have a misunderstanding of what is happening at the receiver on ISS. If we are all transmitting at it and it can't decode any of us then the transmitter is silent. If the setup is anything like most then it won't transmit until it is done receiving as a matter of fact. The QRM we are talking about is at the ISS, not local. For instance, if I'm not decoding anything and keep transmitting while you are trying to get in then we accomplish nothing. Our signals are mixing or tail ending so the TNC ignores us both. What exactly does that accomplish? Using transmitted packets as a gauge for who is trying to get in makes no sense. If we all keep trying to get in at the same time then zero packets will be transmitted. Using your logic one would assume nobody had tried to work the ISS when in actuality everyone did. Also, local QRM is exactly that, local. You may not have a problem with other stations being decoded via terrestrial but that's not the case here in DM14. I have many active ops on ISS around here and have received them without digipeating. I do not blame them for this, it is just part of how it works. Encouraging anyone trying to transmit when they can't hear ANYTHING is just flat out bad advice. I'll do my best to discourage this every time. I would love to hear how you think it is beneficial for a station to transmit when they can't hear what is going on. 73, Mike Diehl AI6GS > On Apr 16, 2017, at 3:18 PM, Stefan Wagener wrote: > > Thanks Mike, > > Again, you don't seem to get the point. Based on your setup, TNC, software etc you will NOT be able to decode every single packet and based on your setup and the ISS position the ISS digipeater will not re-transmit. It's the nature of the beast. No, you are not creating QRM if the ISS does not repeat your packet. Listen to the path of the ISS and you will hear that 50% of the time the radio is silent. It does not TX since there are no valid packets. Where is the QRM? There is none other than in you local environment where nobody cares. Don't discourage those that are trying to make it work. If you want a case, point out the stations and callsigns that create QRM and are not listenting/responding! > > Just check out the last pass over the US.

I don't have a dog in this fight since I don't work packet any more... but at one time I was a statewide packet coordinator and personally took care of numerous dual band packet nodes. I've listened to the audio while at those sites. There may be one thing to consider than a regular 'ground op' doesn't think of... At high altitude, the receiver can hear a LOT and there are a lot of packets that do not get decoded because two, three, even four or more stations will all transmit at once and cover some part of another stations packet, thereby negating each other. (FM capture effect does not really apply for packet unless it's near 100% with clear audio, which is rare.) Because those stations are not hearing each other, they will key up and transmit at will, whether another station is transmitting at the time or not. From the 'digipeaters' point of view, it hears only partial packets, with lots of overlapping signals, so it decodes none. Whether or not the activity is appropriate, I'm not commenting on that... but I'm addressing your question so that you can better decide for yourself that question. My answer to 'where is the QRM?' is... 'The radio is silent 50% of the time, because it cannot decode enough valid packets... true. But the reason it can't decode enough valid packets may well be (and most likely IS) that all the transmitting stations continually overlap each other. (QRM each other)' The error in the logic here is assuming that it doesn't retransmit because it doesn't 'hear'... On the contrary, it HEARS TOO MUCH and can't make sense of the mess to decode it. In other words, it manages to hear a packet in the clear, about 50% of the time. In simple terms, it's most likely silent BECAUSE of the QRM... as opposed to the silence being an indicator of a LACK of QRM as you have suggested. Which would be no different than SO-50 staying silent because 3-4 stations are all keying up at once and SO-50 can't make sense enough to decode someone's PL tone. In both cases... too many stations, bird can't hear... bird does not retransmit. 73 and good luck to all in finding a workable solution. Kevin N4UFO ?

There may have been only 10 stations, the problem is then 8 of them are sending beacons every 30 seconds and have no intention of making a QSO! This is a longstanding problem on the ISS 2m digi. I don't agree about your claims on the reliability of the ISS digi; I have routinely worked it and decoded my digipeated packets to the horizon with an Arrow and HT, even on 70cm. With little doubt I would consider the ISS digi one of out most reliable space based transponders, only not functioning when shut off for more prudent matters aboard the station. The ISS has a particularly sensitive receive, it will digipeat plenty, as with most satellites. As is a common disease among sat ops, people focus more on their transmit than receive. Take a listen to an FO-29 pass on the weekend, odds are you'll hear half a dozen stations calling CQ at the exact same spot in the middle with excessive power, and none of them will make a QSO. Maybe you'll hear a station crank the power up on AO-7 "because they can't hear themselves" and knock it into mode A, ruining the pass for most. It IS QRM. If you are preventing QSOs of people that can hear with blind transmissions, that is QRM. Knock yourself transmitting beacons in Western Australia, but over North America you will hear stations, and in any case you will hear RS0ISS (on the condition that you CAN HEAR. You may assume you are not creating QRM, but you often are. The ISS is not so different than SO-50 actually, people blindly transmitting not being able to hear and sharing a single channel, precluding other QSOs. I seem to recall hearing you on a pass a few days ago and giving you a call (which I heard myself clearly) and you didn't hear it. Maybe just a coincidence. 73, Gabe NJ7H On Sun, Apr 16, 2017 at 5:18 PM, Stefan Wagener wrote: > Thanks Mike, > > Again, you don't seem to get the point.

Thanks for your work as a statewide packet coordinator. That is great! I just worked the last ISS pass 20 min ago and the ISS radio was silent for 20 sec+ in between most packets. NO, I do not believe that the cause is colliding packets, since I can fire off rapid packets and they get repeated quickly, if I choose to and NO, no one has ever told me that I create QRM :-) Traffic was low on the last pass. Made three contacts easily. Hope that helps, Stefan since you don't have a dog in this fight and you are not working ISS packets, ther On Sun, Apr 16, 2017 at 6:00 PM, Kevin M via AMSAT-BB wrote: > > No, you are not creating QRM if the ISS does not repeat your packet. > Listen to the path of the ISS and > > you will hear that 50% of the time the radio is silent.

QRM on almost any satellite path is on the uplink, not the downlink. This is particularly true for modes that allow only one station to transmit at a time (specifically including packet). If more than one person transmits on the uplink wherein their transmissions overlap, neither is properly decoded by the ISS, so nothing is transmitted by the ISS. If this continues for the entire pass, there will never be any downlink transmissions. By your definition, there was no QRM (because you could not hear it - but the ISS did), and you encourage more stations to transmit - thereby making the problem even worse.

If 5 stations are calling him on one frequency and he/she cannot make out a callsign and says, ?Again?? and this continues over and over, the QRM was on the uplink to the human ear by all 5 stations transmitting. You can?t say it wasn?t QRM if he/she failed to respond to any callsign during a voice past. My 2 cents, worth about a penny.

But I don't have any 'proof' in hand and my experiences are merely similar, so a trip to a tower transmitter site won't be effective in this case. I wonder if it's possible to get the astronauts to make a recording of the receiver audio and send it to the ground by other means. X^D? Good luck!

Thanks for your work as a statewide packet coordinator. That is great! I just worked the last ISS pass 20 min ago and the ISS radio was silent for 20 sec+ in between most packets. NO, I do not believe that the cause is colliding packets, since I can fire off rapid packets and they get repeated quickly, if I choose to and NO, no one has ever told me that I create QRM :-)? Traffic was low on the last pass. Made three contacts easily. Hope that helps, Stefan On Sun, Apr 16, 2017 at 6:00 PM, Kevin M via AMSAT-BB wrote: > No, you are not creating QRM if the ISS does not repeat your packet.

I don't have a dog in this fight since I don't work packet any more... but at one time I was a statewide packet coordinator and personally took care of numerous dual band packet nodes. I've listened to the audio while at those sites. There may be one thing to consider than a regular 'ground op' doesn't think of... At high altitude, the receiver can hear a LOT and there are a lot of packets that do not get decoded because two, three, even four or more stations will all transmit at once and cover some part of another stations packet, thereby negating each other. (FM capture effect does not really apply for packet unless it's near 100% with clear audio, which is rare.) Because those stations are not hearing each other, they will key up and transmit at will, whether another station is transmitting at the time or not. From the 'digipeaters' point of view, it hears only partial packets, with lots of overlapping signals, so it decodes none. Whether or not the activity is appropriate, I'm not commenting on that... but I'm addressing your question so that you can better decide for yourself that question. My answer to 'where is the QRM?' is... 'The radio is silent 50% of the time, because it cannot decode enough valid packets... true. But the reason it can't decode enough valid packets may well be (and most likely IS) that all the transmitting stations continually overlap each other. (QRM each other)' The error in the logic here is assuming that it doesn't retransmit because it doesn't 'hear'... On the contrary, it HEARS TOO MUCH and can't make sense of the mess to decode it. In other words, it manages to hear a packet in the clear, about 50% of the time. In simple terms, it's most likely silent BECAUSE of the QRM... as opposed to the silence being an indicator of a LACK of QRM as you have suggested. Which would be no different than SO-50 staying silent because 3-4 stations are all keying up at once and SO-50 can't make sense enough to decode someone's PL tone. In both cases... too many stations, bird can't hear... bird does not retransmit. 73 and good luck to all in finding a workable solution.?

The "Common Problem" is not the lack of activity on the ISS (colliding packets), the problem is the unattended digipeating stations therefor by definition, the downlink signal everyone is hearing. Otherwise you wouldn't know that they are there:-) As I said before lets point them out and deal with it. I just have a hard time with someone claiming universally the 'golden rule" on the ISS (and again and again I am not talking about the SO-50's of the world). I encourage and will encourage folks to experiment with the ISS, trying to to get their packets through even if they don't get their own packets decoded on their side. This is what amateur radio is all about, trying to discover new ways .... Throwing the "book" at folks is not me.

I think all anyone was saying is (as is good practice on any sat, actually anything in ham radio) - listen before you transmit. "Listening" in the case of the APRS sats can be either waiting for a minute or two to see if you decode anything (including the beacon), or literally just turning the squelch off on your rig and listening for packet transmissions by ear. If you're hearing no activity by ear, and/or decoding the beacon but nothing else, great! Maybe it's just a slow pass. If you're hearing multiple transmissions by ear, but not getting any decodes (including the beacon) - maybe you have an issue with your RX and you should address that before transmitting. Otherwise you risk both QRMing other QSOs in progress, and/or having others attempt to respond to you and you won't be able to decode their packets. Just listen first, then transmit. That's the "golden rule" of any ham radio activity, not just sats or ISS digi. ?73? - Matthew ? kk4fem?

However much it may be insisted ISS packet is not SO-50, it is practically the same thing (single channel operating on FM). 73, Gabe NJ7H On Sun, Apr 16, 2017 at 7:18 PM, John Becker wrote: > just turn the thing off. end of all problems. > > > > _______________________________________________ > Sent via AMSAT-BB at amsat.org.

I'm not sure but it seems to be closely coupled with FM repeater operation where stations give a shout out to other stations they know. If only regular FM repeaters worked 10 minutes every hour and a half then maybe ops would realize how precious of a resource FM passes are. I also agree with the lonely pass situation. Out here on the left coast we run into a lot of quiet time. Many times I'm surprised I don't have to turn the bird on. On this type of pass it is perfectly acceptable to work the same stations or put your call out to generate activity to help others find the bird. Even some rag chewing with breaks is perfectly fine given you don't loose situational awareness. I think the situation you're describing is where a rare grid(s) is on or a demo station is on and you get a station who feels the need to call out or work dupes. There are many passes where I've just listened to the magic of radio in action, it has its own rewards. Making contacts is great but you really have to remind yourself that everyone else is trying for the same. It really is OK to have a pass go by where all you do is SWL. 73, Mike Diehl AI6GS > On Apr 16, 2017, at 6:58 PM, Tucker McGuire wrote: > > Hello space bird enthusiasts, > > I have noticed that certain stations on busy SO-50 passes work the same > stations that they have worked on many previous passes when they are in the > same grid.

It is great to stop and say hi to friends but do you do this on a busy highway, no. If we think of busy FM passes like the 405 here in LA you can see where this is counterproductive. If you want to hang out and chat with your friends then us hams have many options. HF, DMR, IRLP, the list is long. We all know if there was a single channel only on 40m with a 10 minute opening and you wanted to say "howdy neighbor" with DX rolling in you might be called a LID. Just like anything else, there's a time and place for saying hi to old friends, doing it in the middle of heavy traffic just isn't the time or place. 73, Mike Diehl AI6GS > On Apr 16, 2017, at 8:09 PM, Ken Alexander wrote: > > I see a new category of LID on the horizon: the operator who likes to say hello to his friends. > > When this is over, will there be any satellite operators left who AREN'T LIDs for one reason or another? > > > > -------------------------------------------- > On Sun, 4/16/17, Tucker McGuire wrote: > > Subject: [amsat-bb] Dupe contacts on SO-50 > To: amsat-bb at amsat.org > Received: Sunday, April 16, 2017, 9:58 PM > > Hello space bird enthusiasts, > > I have noticed that certain stations on > busy SO-50 passes work the same > stations that they have worked on many > previous passes when they are in the > same grid.

(4 diodes, and a siggen at 58 MHz) so they can then use two FT-817?s on the 21.4 MHz uplink and 29.4 MHz downlink) for our next satellite: http://aprs.org/hfsat.html ) Now we want to use an USRP 2922 SDR as the programmabel oscillator around 58 MHz so we can simulate Doppler. Can anyone whip out some code to make the oscillator follow a Doppler Ramp in freuqncy from say 58.100 to 58.900 MHz over a ten minute pass. That should be easy enough for one-observer. Can just be linear for now (simulating a low pass). But then once that is done, we need the driver to then FLIP the Doppler shift instantly in the opposite direction to simulate the shift seen by another observer at the other end of the pass. This is another layer of complexity, but we will simply have a push button input to shift between the two states when one station or the other is transmitting. But for now, the students just need some handholding to get the basic SDR acting as a signal gen at 58 MHz and how to input the freqncy ramp to it.

Hi Bob, You can take a look at gr-gpredict-doppler. https://github.com/wnagele/gr-gpredict-doppler Together with one or two (for the case of two observers) instances of Gpredict, it can do what you want. 73, Dani.

I did a similar project for my graduate SDR class a few years ago where I built a 'satellite simulator' using USRPs. Trust Me you don't want that code (I was new to all this at the time), but below are my two cents from lessons learned and new things since then. 1. The USRP 2922 SDR from national instruments is an Ettus Research (now owned by NI) USRP with an SBX daughtercard installed. The RF output of this device is between 400 MHz and 4.4 GHz. So if you are looking to use it as a programmable LO, it likely won't do. (also, kind of moot, but if you buy direct from Ettus Research, it is cheaper). What I would recommend is an Ettus Research N210 (https://www.ettus.com/product/details/UN210-KIT, $1896) and a different daughtercard that will work at the required Frequency, like a BasicTX that operates from 1-250 MHz (https://www.ettus.com/product/details/BasicTX, $83). While your at it, you might as well get the BasicRX so you can monitor the spectrum with the same device (has independent tuning between TX and RX, and you can install both daughtercards in one N210). 2. If you are using USRPs you are probably using GNU Radio (Awesome!). As Dani mentioned, there is a gr-gpredict-doppler out of tree module that can be linked with Gpredict to control tuning in GNU Radio. This is for sure probably the simplest most direct way to get up and running, so I second that idea (feel free to ignore my number 3). For my graduate class project, I used the UDP server feature of plain ole 'predict' (actually 'predict-g1yyh') to do achieve basically the same goals. The problem I ran into with this type of interface was time (like UTC time). At the time I didn't understand how to properly use predict via the UDP server function to query it for different time stamps other than 'now.' End result was I could only run simulations when an actual satellite was overhead, pretty clunky. Gpredict has a pretty simple interface for controlling time though (to move the simulation into the future or back into the past), and I'm sure it can be done in predict via the UDP interface, I was just new to everything, so lots of 'student operator error.' I mention it only as a 'watch out for this one' type thing. 3. One way to think of GNU Radio is that the 'flowgraph' or 'modem' is just a python class, which can be imported and controlled by large python programs (you can start/stop the flowgraph, update parameters, etc.). So for a bit finer control, and if I could do it all over again the way I would probably go, is another option called 'pyephem' (http://rhodesmill.org/pyephem/). This handy little python module is capable of importing TLEs and executing the SGP4 algorithm for orbital propagation. In addition you can feed it ground station coordinates and times (UTC) and then query it for az/el/range/range rate (doppler) information. Its basically a python version of the 'engine' that runs under the hood of predict or gpredict. So for a bit finer resolution, and to make a single compact python program that doesn't rely on an external program (only one 'thing' to execute and control), you could use pyephem to compute the doppler values and then feed that to GNU Radio. To be clear though, this is not a GNU Radio out of tree module, it is a standalone python module, and some coding would be required to merge the two (I would run pyephem in one thread or process with callbacks to control the GNU Radio parameters). 4. Last little nugget, when you install GNU Radio, it comes with a handy little set of executables. One of the commonly used ones is 'uhd_find_devices' which locates connect USRPs (IP or USB based connections) and returns basic information about them (IP addr, serial numbers, installed daughtercards, etc). If 'uhd_find_devices' works and returns info, then when you execute the flowgraph it should be able to locate the device. Another common one is 'uhd_fft' which is a quick way to get a spectrum analyzer like display up and running. The other lesser known tool is 'uhd_siggen' or 'uhd_siggen_gui.' This little tool lets you quickly generate transmit signals. So for a 'static test' to make sure the USRP is working as an LO (right power levels, frequency, etc.) you can use this to get a quick feel for whether or not it will work for your application. It has a bunch of sliders for controlling transmit gain and center frequency so you should be able to 'manually' test out your system and verify things are working before diving into the complexities of custom flowgraphs with the doppler simulations. Hope this helps. Cool Stuff!

You'll have to put in many years of crankiness before you can claim that title. You raise a point that has persisted for quite a while regarding FM Satellites. Experienced operators usually follow the proper protocol/etiquette on the single-channel resource. They rarely chit-chat unless the bird is idle. As with anything else, newbies are learning the ropes. The FM SATs, as we all know, are where the new folks start out because they are easy due to readily available equipment. These operators are trying to figure everything out at once - the frequencies, the antennas, the PL, the AOS/LOS/AZ/EL, the protocol, etc., etc. Until they figure all of these things out, the rest of the users are going to have to endure problems of various kinds. It's the utter reality of the situation. However, they are the "new blood" that we need to keep this aspect of the hobby growing. And, believe it or not, not all SAT Ops are Grid Chasers. Some only care about the thrill of pointing a signal up toward the sky and saying hello to someone via something flying through Space. We have no choice but to co-exist in this environment. It is what it is. A good primer for new operators can be found on John K8YSE's website at: http://www.papays.com/sat/general.html All we can do is be good examples for the new/other users. When someone is operating from a rare Grid and we already have it confirmed, stay clear. If the pileup dies down and no one is calling, it's perfectly fine to say a quick hello to let them know they are being heard. During routine passes, if you hear a new Call, it's nice to give them a shout so they get the operating experience. 73 & GL 2 All, Bob K8BL ________________________________ > On Apr 16, 2017, at 6:58 PM, Tucker McGuire wrote: > > Hello space bird enthusiasts, > > I have noticed that certain stations on busy SO-50 passes work the same > stations that they have worked on many previous passes when they are in the > same grid.

With voice communication, one can sometimes pick up the start or tail of a call sign, as the astronaut demonstrated, and use that to filter a second try. With digital, any bits that get corrupted result in no reception at all. I hate to suggest this, and admit I am assuming a cause without supporting evidence, but it might be necessary to remove the "vanity" aspect of ISS digipeating, and take down or hide from general view the reporting sites that support it. While a useful tool for troubleshooting, I suspect the vanity aspect of seeing your call in a public list day after day from an unattended station may be too strong a draw for some, resulting in the clogged channel. The SatGates that monitor for ISS and other APRS satellite traffic are still important part of the infrastructure, so that the information can be datamined from APRS-IS if you need it for troubleshooting. But the consolidated lists of who has been seen digipeating through the ISS, I think, may be contributing more trouble than they are worth.

I have some good recordings of voice stations getting a call back when as little as a single letter of their call was heard. It's amazing how well we can learn the voices of other ops when you're on regularly. This simply doesn't happen on packet. Another complication is that it is on simplex. That means on a 10 minute pass the maximum amount of time possible to digipeat is 5 minutes if the channel is fully saturated. Subtract out the ISS beacons we end up with less than 50% of the pass available for ISS to hear you. I'm not sure what the best solution is. You do bring up an interesting point about APRS-IS. Maybe it's possible to have them black list fixed beacon stations and remove the vanity aspect like you mentioned. 73, Mike Diehl AI6GS > On Apr 17, 2017, at 1:26 PM, Greg D wrote: > > Gabriel Zeifman wrote: >> It's not complicated.

Essential, actually. Not suggesting it should change, or is directly involved in the problem. So, doing some more digging, the vanity site I thought of was http://www.ariss.net/, and a few others that are similar. BUT, the map, and the table below it, clearly show stations that have live operators behind them, as demonstrated by the 2-way messages listed. And the more I look into the stations list, I'm thinking that Steve is doing some pretty clever filtering to weed out the ones that are just beacons (though I do see a few in there). I thought I saw a bunch that appeared to be unattended, but now I'm not so sure. So, perhaps, I'm off a bit about the vanity aspect of the unattended beaconing? Are there sites that list row upon row of call signs that aren't live? If there isn't a billboard for unattended beacons, why would someone engage in doing that? A vanity beacon that only the originator knows about isn't very vain. Perhaps something else, but not that.

References: <1003754611.2270908.1492473507146.ref@mail.yahoo.com> Message-ID: <1003754611.2270908.1492473507146@mail.yahoo.com> Hi Philip, I just made a trip up to Marion with the XYL to operate from EM85 last month, I had a good number of takers, even having to share the pass with another rover operating from a much needed grid to the south. I try to keep a list of grids around me and the more avid grid chasers that need them. That list will dwindle if not empty after such a trip, but within a short time, it grows again as new folks come into the hobby and get the bug. (AMSAT journal ran an article about the XYL & I going up there about 2 years ago, there and another grid. Fun day trip for the wife!) That said, I only have one callsign listed for EM85 at the moment, but that doesn't mean more don't need it. Not everyone can necessarily make a specific pass on a specific day. Yes, I keep EM95 fairly active and the EM96 line is just right up the road from me about 15-20 minutes. But, I have a about 5 on each list for EM84 and EM86 and I am sure there are more that need them. Bottom line, there are no regular sat ops in those grids. AND no regular op that I know of in EM85 (or else I wouldn't need to drive the hour or so up there periodically.) =^) So I am sure even an irregular presence in EM85 would be welcome! I suggest you make a note on your QRZ page that you welcome sked requests... because those of us afflicted with the grid chasing disease will ask other ops things like, 'Who did you work in XX99?' and then try and scare up a sked. As for gear, a pair of 817s is great... if you can't quite afford that, a full duplex HT or a pair of HTs for FM will do. Have a look at my gear on my special QRZ page and if you like the 'bag' idea, I can send you links to where to buy that particular bag and really good shoulder straps. (Also the power cable, battery, etc.) I got the bag and straps idea from N8HM who has about perfected the art of the 'wearable sat station'. https://www.qrz.com/db/N4UFO/P Whatever you do, just make sure to have fun... that's the name of the game. Sometimes we can get wrapped up and take the hunt too seriously. As has been said before. if you aren't having fun, you aren't doing it right.? 73, Kevin N4UFO From wageners at gmail.com Tue Apr 18 00:30:08 2017 From: wageners at gmail.com (Stefan Wagener) Date: Mon, 17 Apr 2017 19:30:08 -0500 Subject: [amsat-bb] Thoughts on ISS packet switch back to 145.825 MHz (long) In-Reply-To: <72B4E0E5-CFDA-443B-9F12-A53E80FC6674@gmail.com> References: <4cf7c608b22d092ae062393dd550f977@mail.gmail.com> <651D80DE-BD7D-4AF5-9ED3-0C624F4F9335@gmail.com> <23621b4e-5b6a-bbc5-d0a7-1ca4c9d7ef49@k6ccc.org> <255B194C-9599-4300-9292-AD04D1E79C9C@comcast.net> <28426faf-5cce-16b5-2763-4698c7ee83ff@big-river.net> <72B4E0E5-CFDA-443B-9F12-A53E80FC6674@gmail.com> Message-ID: Well Mike, Here is my log from the last pass. It shows 29 digipeats (~75% decoding success at my station) for 8+ minutes. Each packet is barely 1 1/2 seconds! That is a utilization of less then 5% assuming my math is correct. In addition, asking for "blacklisting of licensed operators" is something I certainly will not support and fortunately neither does the FCC. 73, Stefan, VE4NSA ..........................................

Please also prove me wrong that a simplex channel can support more than 50% utilization. The fact only 5% of the pass had the ISS radio transmitting can either prove nothing or support the fact that there is so much QRM AT THE ISS that very few complete packets were heard and digipeated. As far as black listing goes the FCC has no authority over what data a site decides to exclude from showing.

Nothing is taking place any differently than would have been happening before October. I have digipeated through ISS with my FT1DR to show up on the ISS Heard list. That is obviously what some of the station on the log provided were doing as well. That is totally acceptable. If you see a response from ISS there should be no need to try further. The key of course is to manually transmit and not setup the beacon. The FT1DR is not conducive for easy messaging. I have done successful messaging with an APRSIS32/TNC setup in the past. I will be trying APRSDroid to do the same in the near future. 73.

My point was just general simplex leaving protocols and other factors out just to keep it simple. Like you point out, adding in overhead we loose even more time. The major problem though is that the terrestrial stations can't hear each other so the door is wide open for collisions. Which is why unmanned beacons are trouble. I think what is being lost here is what is happening at the bird. It's not like a linear or FM transponder on full duplex where we can hear what is happening. We all know when we have a dead carrier on voice because the bird is instantly transmitting what it hears. Now in the case of simplex if a dead carrier was thrown at ISS for the whole pass then how exactly would we know? One could assume nobody was on. Lots of packets heard from the station can prove a lot were heard and decoded properly. A lack of packets can indicate two things, either it wasn't receiving a lot or there were too many. That's the point I've been trying to make this whole time. Beacons should be seen for what they are, stations just simply increasing the odds of collisions at the ISS receiver. 73, Mike Diehl AI6GS > On Apr 17, 2017, at 7:45 PM, Greg D wrote: > > I believe APRS Packet is basically an Aloha network.

This switch was done later than normal (normally done Sunday evenings UTC) due to the Easter Holidays. 73s Jim G3WGM and the FUNcube Team ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Low temperatures give higher freqs!) FUNcube-2 aka FUNcube on UKube The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/EO88 Nayif-1 FUNcube-5EO88 is presently operating in autonomous mode. The transponder isoperational when the satellite is in eclipse, ie the solar panels are NOTbeing illuminated.When the transponder is switched off, the telemetry beacon is on full power,when the transponder is on the beacon it is on low power.The transponder frequencies are:Uplink: 435.045 ? 435.015 MHz LSB (inverting)Downlink: 145.960-145.990 MHz USBTelemetry Tx: 145.940MHzAll FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

Nothing is taking place any differently than would have been happening before October. I have digipeated through ISS with my FT1DR to show up on the ISS Heard list. That is obviously what some of the station on the log provided were doing as well. That is totally acceptable. If you see a response from ISS there should be no need to try further. The key of course is to manually transmit and not setup the beacon. The FT1DR is not conducive for easy messaging. I have done successful messaging with an APRSIS32/TNC setup in the past. I will be trying APRSDroid to do the same in the near future. 73.

Why do you keep making me build a new modem to copy data every time you build a new satellite? Can't you just use a TNC? Why not fly a W0RLI packet BBS? 2. Why can't you just build a flying FM repeater, so I can use my regular equipment? The techies who built satellites explained patiently both of these were Really Bad Ideas; both are extremely poor choices from a technical standpoint. They are single channel, and use one of the most inefficient modulation schemes known to hams. We have spent the past 25+ years proving the techies were right on both accounts. Consider the numerous detailed discussions concerning problems with both over the past few days. Those techies would be, and perhaps in some cases are, nodding knowingly at seeing the validity of those objections being born out. But the users have also been proven right. Satellite APRS manages to work despite these limitations, and FM satellites are often in use AOS to LOS with normally good cooperation. (Everybody is a newbie sometime.) The ability to use rather simple equipment, easily understood, has won out over technically "sweeter" solutions. Users have tacitly decided that the limitations are a good tradeoff. The proof is the number of successful QSOs and Dxpeditions reported. However, the limitations are inherent in the chosen technology, and education, innovation, consensus, and courtesy can only do so much. Keep in mind there are other voice options in the form of linear satellites now, and with only slightly greater complexity. You can chase DX, grids, and rag chew at the same time without taking away resources from other users. To borrow a phrase from AMSAT-NA's Official Curmudgeon, Tom, K3IO, "But wait, there's more!" Digital voice and data systems are being developed by the current generation of techies which will make microwave systems, and the resulting bandwidth, available to the everyone using digital signal processing and eBay parts. As Phil Karn, KA9Q, puts it, any sufficiently advanced modulation scheme is indistinguishable from noise. But with that noise will come the ability to accommodate voice, TV, and data simultaneously. For some, the tradeoff of greater complexity for almost unbelievable capability will be worth it. For others, simplicity and familiarity will win out. In both cases, that is in the best traditions of amateur radio. 73s, Alan WA4SCA Curmudgeon (jg) From amsat-bb at wd9ewk.net Tue Apr 18 16:24:36 2017 From: amsat-bb at wd9ewk.net (Patrick STODDARD (WD9EWK/VA7EWK)) Date: Tue, 18 Apr 2017 09:24:36 -0700 Subject: [amsat-bb] AO-73/FUNcube Mode switch In-Reply-To: References: <160781.62abfb43.436008a2@aol.com> <9FEB9308451F4BF6B49AE43E026DBDC0@jimPC2> Message-ID: ?Jim, Thanks to you and the FUNcube team for the extended period of transponder time over the Easter holiday. It was nice to have the transponder available for a demonstration last night at a nearby college. Using my FT-817ND, SDRplay RSP1, and an 8-inch Windows 10 tablet running HDSDR, I was able to work two Mexican stations and a station in Las Vegas. The crowd saw the tablet's screen, where the transponder and the digital telemetry were easy to pick out of the waterfall display. 73!

Last night's presentation and demonstrations for the Mesa Community College Amateur Radio Club (KM7CC) in Mesa, Arizona, was a great way to spend an evening. Along with the presentation, satellite pass timing allowed for two demonstrations, using the ISS and AO-73. When I drove to the college, I arrived just in time for an eastern ISS pass around 0120 UTC - 40 minutes before the start of the meeting. I was able to make a couple of QSOs using my TH-D74A and Elk antenna, and ensure the HT was ready for a possible demonstration later in the evening. I had planned on using either AO-73 or EO-88 for a demonstration after the meeting around 0350-0430 UTC, but the meeting agenda had a break around 0300 UTC - just in time for a western ISS pass. Unlike many radio clubs, the presentations at the KM7CC club are done first. Knowing a break was scheduled, and that the ISS was passing by around that time, I made sure the presentation fit within the schedule. Then everyone went outside for the ISS pass. We weren't able to see the ISS, but I wasn't the only one reading the packet traffic on that pass. One of the attendees had a brand new TH-D72A and Arrow Yagi, and I helped him set it up to copy the packet traffic on 145.825 MHz. The two of us had crowds watching the radios and listening to the packet traffic, and others were using their mobile phones to see this happening on the ariss.net web site. I was able to work two of the 3 stations I saw on the pass - thanks to KK6OTJ and AD5MT in southern California for the quick exchanges. The meeting went for about 25 minutes after the break for the ISS pass. This meant the AO-73 pass just before 0400 UTC was available for one more satellite demonstration. Since I mentioned my portable all-mode satellite station during the presentation, including an SDRplay receiver and Windows 10 tablet running HDSDR, I used that setup out for the AO-73 pass. Not many were on that pass, but I think I worked everyone else I saw and heard. Tony XE1H in Guadalajara started things off. Tony also operates using a club call sign, XE1TD. A contact was made with that call sign, too. A couple of minutes later, Brad W5SAT in Las Vegas showed up for the third and final contact for me on that pass. With the Windows 10 tablet and HDSDR, I used the waterfall display to show where the digital telemetry was, along with seeing the width of the transponder. This was a great practical demonstration of using SDR in ham radio, something that was discussed by the club during the meeting. Thanks to Charlie NJ7V and the KM7CC club for the opportunity to visit the club, give a presentation, and have two demonstrations last night. And I still have two more presentations later this week... 73!

That's all well and good that he wants to see himself online, but maybe he needs to look closer because his packets ARE getting forwarded by Igates so that isn't the problem. Bottom line is that he's beaconing way too often and creating a problem for people that are actually trying to make a contact and aren't so worried about seeing themselves online.

I will be leaving direct to Europe from the K6G expedition, first ops being on 4/30. First stop is a long layover in Iceland. BIKF airport happens to be right on the HP83/84 line, so I plan to operate from there. Scheduled times on the ground are 4/30 1345Z - 5/1 0740Z, subtract a bit for customs and security time, plus I'll probably be visiting the Oceanic Air Traffic Control Center at some point. West Coasters and ops in the center of NA take note, there is likely only ONE usable pass (sadly). This is the 1956Z pass of AO-7, which has footprint over basically the entire continent. I sure hope the QRO lids remain at bay and don't flip it to mode A, this is a very rare opportunity. Plenty of passes possible for the East Coast and Europe. After that, I will be heading to Amsterdam for four nights, then Brussels for one night. Not sure how much operating in each country but I hope to work at least one pass to the US from each towards my CCXD. The second week will be in the British Isles. May 6-8 on Jersey, 8-10 on Guernsey, and 10-13 on Isle of Man. I will be staying on the west coast of each island to maximize possibilities for low passes to North America. To wrap it up, I will do a day roving in Northern Ireland and the Republic of Ireland with George MI6GTY before heading back home. This is a trip with my family, so I won't be on every pass. I will make my best effort to be on good North America bound passes, and it should be easy to cover Europe as well. AO-7 will be the primary NA bird, but some use of FO-29 will be possible. All countries are CEPT TR61/01 and I have gotten LoTW certificates for all calls. All QSLing will be through LoTW, but if necessary I can get some cards made up, which will be available via direct NJ7H as usual. Callsigns: Iceland TF/NJ7H Netherlands PA/NJ7H Belgium ON/NJ7H England M/NJ7H (short layovers, not sure if will be used) Jersey MJ/NJ7H Guernsey MU/NJ7H Isle of Man MD/NJ7H Northern Ireland MI/NJ7H Republic of Ireland EI/NJ7H 73, Gabe NJ7H From diehl.mike.a at gmail.com Wed Apr 19 00:59:13 2017 From: diehl.mike.a at gmail.com (Mike Diehl) Date: Tue, 18 Apr 2017 17:59:13 -0700 Subject: [amsat-bb] ISS Beaconator In-Reply-To: References: Message-ID: <6CF73CC4-5399-4719-9C32-4D093A73A53B@gmail.com> Jeff, It's quite clear the station is running an unattended beacon, just look at the packets. Even if this was a live person at a keyboard it would still be borderline jamming. That's kind of the definition, constantly transmitting with no intent on making a QSO and blocking other stations from doing so. I can only hope that the station is doing it on accident due to some improper configuration and not doing it on purpose. The purpose of packet RADIO over satellite is not so that you can see yourself on the internet, we have many other ways to accomplish that, like this Internet BB. You should really consider why a station needs to beacon at 3 second intervals to see if he shows up on a website. The latency alone can be greater than that so they are transmitting again without sufficient time to know for sure they've been gated. To your point about the lack of quality gates, if this station wasn't constantly transmitting it might hear something and gate it. Makes the problem worse, not better. 73, Mike Diehl AI6GS > On Apr 18, 2017, at 4:38 PM, Jeff wrote: > > All this is demonstrating is that N3FCX is watching the ARISS site to see himself/or if his message has made it to the internet.

I copied those packets directly via RF which means all of them were being digitpeated by the ISS when I decoded them. They were being seen by anyone in the footprint and picked up by other IGATE stations. Secondly, I was running a passive IGATE, forwarding what I received to the APRS-IS. Based on your statement, if I took down my IGATE, should the other station transmit more often? My posting of those packets was not meant to insult anyone or cause any embarrassment. I posted what I received at my station. Readers can draw whatever conclusions their hearts desire. I didn't insult anyone by license class, their goals, etc. Call my email ridiculous if you will, but it is not my station broadcasting packets via the ISS every 5-10 seconds when in the footprint. 73 Clayton W5PFG On Tue, Apr 18, 2017 at 6:38 PM, Jeff wrote: > All this is demonstrating is that N3FCX is watching the ARISS site to see > himself/or if his message has made it to the internet.

At first I only looked at your email. I know he doesn't run unattended, so I don't know what he is doing. Us old guys lose it, it's just a matter of time, you will see in 30 years :-) I will try and contact him to see what's going on.... Here's what I found on APRS.FI... 2017-04-18 17:23:14 EDT: N3FCX>DJFT2R,RS0ISS*,qAR,KD8THX-6:'g.7l <0x1c>#/]SP= 2017-04-18 17:24:16 EDT: N3FCX>DJFT2R,RS0ISS*,qAR,KB3KBR-6:'g.7l <0x1c>#/]SP= 2017-04-18 17:24:54 EDT: N3FCX>DJFT2R,RS0ISS*,qAR,NZ4D-6:'g.7l <0x1c>#/]SP= He should of saw his first TX that got DIGI'd, but maybe for some reason he didn't, I don't see why, but I also don't know why this indicates that this is the end of the world, but will look into it, best I can.. 73 Jeff kb2m -----Original Message----- From: Clayton Coleman Sent: Tuesday, April 18, 2017 9:05 PM To: AMSAT-BB ; Jeff KB2M Subject: Re: [amsat-bb] ISS Beaconator Jeff, I encourage you to look more closely at the packets in my original email and at the raw packets on ARISS.net. I copied those packets directly via RF which means all of them were being digitpeated by the ISS when I decoded them. They were being seen by anyone in the footprint and picked up by other IGATE stations. Secondly, I was running a passive IGATE, forwarding what I received to the APRS-IS. Based on your statement, if I took down my IGATE, should the other station transmit more often? My posting of those packets was not meant to insult anyone or cause any embarrassment. I posted what I received at my station. Readers can draw whatever conclusions their hearts desire. I didn't insult anyone by license class, their goals, etc. Call my email ridiculous if you will, but it is not my station broadcasting packets via the ISS every 5-10 seconds when in the footprint. 73 Clayton W5PFG On Tue, Apr 18, 2017 at 6:38 PM, Jeff wrote: > All this is demonstrating is that N3FCX is watching the ARISS site to see > himself/or if his message has made it to the internet.

Our website is at: http://sebastopolschools.org/brook-haven/ Our FaceBook page can be found at: https://www.facebook.com/brookhavenschool/ The students and staff are very excited about this opportunity to speak with an astronaut on the ISS. We sincerely appreciate everyone who has helped to make this possible! Participants will ask as many of the following questions as time allows: 1. What are the most dangerous jobs on the ISS and what has been your scariest moment? 2. When you return to Earth what is the biggest adjustment to your body? 3. Does the moon look closer in space? Do the phases of the moon look the same as on earth? 4. What special things did you bring with you to remind you of your family? 5. How do you adjust to not having a regular sunrise and sunset? 6. How do you adjust to not being able to sit down or lay down for months? 7. What evidence of climate change have you seen from the ISS? 8. Does an animal's biology determine whether or not it can go to space? What animals have been on the ISS? 9. What medical examinations and vaccinations do you need before you can go to space? 10. If you could bring one thing back from the ISS what would it be? 11. What is the level of danger on a day-to-day basis? 12. What is your favorite thing to do in space? 13. What scale / period of time do you use? 14. Do you get dizzy or off balanced in space and if so, what do you do about it? 15. Is time different in space than it is on earth? 16. Are there medical risks with going into space? 17. How much radiation are you exposed to in space vs. earth? 18. What types of plants are you able to grow in space? 19. What is the most important project / experiment you are working on? PLEASE CHECK THE FOLLOWING FOR MORE INFORMATION ON ARISS UPDATES: Visit ARISS on Facebook. We can be found at Amateur Radio on the International Space Station (ARISS). To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD 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.

ITF-2 has two communication systems, A and B, and switches them every 50 minutes. CW beacon could be received clearly in the pass which was in the period of system A. The system B has the antenna to demonstrate in space. CW beacon which seemed to be from B has been received several times at our grand station from Apr. 15 (JST), but the intensity is still week. Now, we have been investigating the cause, and doing our best for recovery. Due to this problem, signals may be very weak, or not be heard in ITF-2 pass. Please note this. We would be glad if you could send a report in the case of no signal from ITF-2. Reception reports can be submitted at: https://operationitf-2.blogspot.jp/p/blog-page_58.html Operation information of ITF-2: http://operationitf-2.blogspot.jp/ Atsushi Yasuda, JI1OEH University of Tsukuba Satellite project From cspacone at socal.rr.com Wed Apr 19 16:23:31 2017 From: cspacone at socal.rr.com (cspacone at socal.rr.com) Date: Wed, 19 Apr 2017 16:23:31 +0000 Subject: [amsat-bb] ISS Beaconator II In-Reply-To: Message-ID: <20170419162331.OOB6P.204089.root@cdptpa-web03> Agree.

Quite easy compared to C.A., both in terms of licensing (how much simpler can it be than having an FCC Amateur Extra license with CEPT TR61/01, just add appropriate prefix and operate), and health + security. That being said, I had a blast on my Central America trip recently to Belize (V31NJ), Guatemala (TG7/NJ7H), and Honduras (NJ7H/HR9). It was easy to attain licenses or permission to operate in each country and always felt comfortable while operating. In Belize even had three locals plugged in with me on a pass of AO-73! They we're very exited when I worked Clayton W5PFG and told them he was in Texas, and later Patrick WD9EWK in Arizona. I pretty much always had a good internet connection (cellular or local wifi), so it was easy to make sure everyone got quick QSLs! Most contacts were uploaded to LoTW under an hour after they occurred (instant gratification, what can I say). 73, Gabe NJ7H On Wed, Apr 19, 2017 at 1:26 AM, Norm n3ykf wrote: > Just think: If you'd chosen to go to Central America or those > environs, anti malarials would be the new morning ritual.

How are you? All is well I hope? Still with DirecTV? We are very busy with work - I've been building new master control services and we are doing a lot of international expansion. The new facility is finally making some progress. I changed my call sign last year to W5SAT (get it SAT, satellite). I just picked up an IC-7300 - nice little rig actually. Also I have been interested in 6 meters - meteor scatter lately but also have the e-skip season coming up. Been branching out a bit from doing mostly satellite operations. Ok, talk to you later if you are sitting around bored give me a call and catch up.

Message-ID: Hello everyone. While the ISS packet digipeater is off for the crew docking today, I thought it might be a good time to see what I could learn from the group in regard to the rather drastic reduction in performance (both ways - TX & RX) that I've seen since the Space Station's digipeater moved back to 2-meters. I noticed this from day-1 and might have even commented on it previously. But now that some time has passed and a good number of you reading this have had your own experiences with the ISS back on 2-meters, I had to bring it up again. I realize that is a complete apples/oranges situation... different radios & antennas on BOTH ends, different band propagation, etc., etc. But here is my dilemma... While I have been enjoying the very positive reports from many of you, I have also been in touch with some hams from various locations that, like me, can't buy a connection. And unlike myself, these are experienced operators who regularly could connect to the ISS on 70cm across perhaps half the width of the U.S. Also, to the best of my knowledge, these same amateurs were very successful on 2-meter packet to the ISS before the original radio failed. So yes, I know this is like asking why two different cars drive differently, but as I said my confusion is how and why others are seeing so much success. One more stick on the fire is that my iGate is also basically deaf now, even though I have put it on an appropriate 2m antenna and of course changed the frequency settings. I was enjoying an exceptional number of iGate relays to the website on 70cm, but next to zero on 2m. (Please let me add that my 2-meter packet setup works very well to a local digipeater or on terrestrial APRS. Also, my iGate hears extremely well if I move it to 144.39) Getting digipeated is fun, but frankly I would be happy to just HEAR the thing again. So, I don?t really think it?s competition on the band & some of us not being heard, but rather something more in the RF arena. As always, observations and suggestions from everyone are appreciated! -Scott, K4KDR Montpelier, VA USA From jimlist at zoho.com Thu Apr 20 19:20:24 2017 From: jimlist at zoho.com (Jim Heck G3WGM) Date: Thu, 20 Apr 2017 20:20:24 +0100 Subject: [amsat-bb] AO-73/FUNcube Mode switch Message-ID: <0F0D127DE63E474AB46F83A0C09384ED@jimPC2> Hi Folks, This is to let you know that I have just switched AO-73/FUNcube into amateur mode, with transponder activated 24/7. Early this week due to ground station availability. As per normal, we will switch back to autonomous mode on Sunday pm UTC. 73s Jim G3WGM and the FUNcube Team ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Low temperatures give higher freqs!) FUNcube-2 aka FUNcube on UKube The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/EO88 Nayif-1 FUNcube-5EO88 is presently operating in autonomous mode. The transponder isoperational when the satellite is in eclipse, ie the solar panels are NOTbeing illuminated.When the transponder is switched off, the telemetry beacon is on full power,when the transponder is on the beacon it is on low power.The transponder frequencies are:Uplink: 435.045 ? 435.015 MHz LSB (inverting)Downlink: 145.960-145.990 MHz USBTelemetry Tx: 145.940MHzAll FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

In-Reply-To: References: Message-ID: <2476BE37F99E4A5093707DD5AEB34A2C@CSI9020> I?ve gotten a number of excellent replies to my question, but since they were all off-list, I thought I would post a short summary in case anyone else was interested. One reply that taught me a lot referenced the situation that has already been discussed regarding the very large volume of traffic being directed towards the ISS since it returned to 145.825. As explained in the note, if a digipeater is flooded with transmissions to the point that many (most?) cannot be decoded, then naturally it has nothing to re-transmit back over the air. That is a very valid explanation for why I might not be HEARD, nor receive very much on the downlink. And my iGate certainly can?t forward much to the website if successful digipeats are way down. While that might explain the situation over the Eastern US, I got a ?same situation here? from Australia. So, I have to continue wondering if it?s more than just congestion. Another ham that is seeing closer to normal performance is operating at higher power than many of us. So, that is another vote in the direction of a ?too busy? receiver on the ISS with only a few contacts getting through. Time will tell; I just wanted to share those informative off-list comments. Many thanks to all who replied. -Scott -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- Scott wrote: > Hello everyone. > > While the ISS packet digipeater is off for the crew docking today, I > thought it might be a good time to see what I could learn from the group > in regard to the rather drastic reduction in performance (both ways - TX & > RX) that I've seen since the Space Station's digipeater moved back to > 2-meters. > > I noticed this from day-1 and might have even commented on it previously. > But now that some time has passed and a good number of you reading this > have had your own experiences with the ISS back on 2-meters, I had to > bring it up again. > > I realize that is a complete apples/oranges situation... different radios > & antennas on BOTH ends, different band propagation, etc., etc. But here > is my dilemma... > > While I have been enjoying the very positive reports from many of you, I > have also been in touch with some hams from various locations that, like > me, can't buy a connection.

While I have been working on perfecting my dual HT handheld satellite operation methods, I discovered that I simply don't have enough hand's, ears, and eye's for everything. With this limitation in mind, I designed a simple circuit board to interface a headset with a pair of HT's, and an audio recorder. The board as designed can interface to a pair of FT-60's via 3.5mm TRRS cables, or a VX-8 with Yaesu's CT-M11 cable. RX audio is sent to a stereo headset (in mono, of course) and to one channel of a stereo recorder. Microphone audio from the headset mic is sent to the TX radio and to the other channel of the stereo recorder. This way, the recorder should capture both sides of the QSO without issue. The recorder has 2 pot's for level adjustment of both the TX and RX audio levels to the recorder. I also included a trimpot to adjust the bias level of the microphone, should one wish to lower it for any reason, as well as a header to install a PTT switch. My plan was to mount a momentary switch on a handle I plan to make for my arrow antenna. I will have 2 extra boards available in a few weeks time when they get back from my board fab house. If anyone is interested, I can drop one of these extra's in the mail, and I would ask for about $25 for them. I can make more if there is a large interest from the group. Enjoy. Mike, AE0MT.

The Camb- Hams have been activating the Scottish Isles each year since 2008. As in the past, ten or more operators will be active on all bands and many modes from 4m to 80m, 2m & 70cm for Satellites and 2m & 23cm for EME. The HF bands will be covered by four simultaneous stations while the 6m & 4m stations will have a great take-off towards the UK and Europe. All stations will be able to run at the full UK power limit. EME operations will use 150W to 55 elements on 23cm and 400W to 17 elements on 2m, primarily on JT65, but also available for CW skeds - if your station is big enough. Satellite operations on 2m & 70cm will use X-Quad antennas and a fully automatic Az/El tracking system. Activity is planned on AO-7 (mode B), FO-29, SO-50, AO-85 & AO-73. All the up-to-date plans and progress will be on-line at http://dx.camb-hams.com. Most importantly, this is a group of good friends doing what they enjoy, so please give them a call and enjoy the trip with them.

Message-ID: Hi everybody. This is essentially a request for what I believe the scientific folks call "peer review"... I continue to try to understand why none of my equipment has been receiving the ISS digipeater very well since the switch back to 2 meters, despite the fact that the same hardware does well on terrestrial packet and in the case of 145.825 in particular, I have even received packets from PSAT since re-configuring for VHF reception on my Raspberry Pi / RTL-SDR iGate. So, my point is that it isn't that NOTHING is working on 2-meter packet or 145.825 here. And as I've mentioned in the past, I hear from others with similar stories so we're not sharing hardware or location. This evening there was a favorable pass here and I see on ariss.net that several stations were digipeated while the ISS was over the U.S. Great news! I monitored that pass in receive-only mode with the same type of TXCO version-3 RTL-SDR that I use for my iGate. The results were very strange and I hope incorrect. I certainly would appreciate it if someone might repeat my test when time permits. Here is an image showing my SDR tuned to the local NOAA Weather Radio on 162.475. By all appearances, my frequency display is accurate in the VHF band. https://www.dropbox.com/s/w1dll06xwinteap/NOAA-Wx-Radio-on-freq.png?raw=1 ... without changing any settings other than frequency, the following image shows a Spectra-Vue plot of my reception of the packet transmissions from the ISS on this evening's pass: https://www.dropbox.com/s/s46o3pi87yk9t2h/spec-view.png?raw=1 ... I took a ballpark stab at the center point of closest approach and unless I did something awfully wrong, it's roughly 5 KHz above the expected 145.825 frequency. If by any chance this is accurate, it explains why I've been seeing poor reception here. (On the other hand, if my observations are completely wrong and flawed, this makes just over 1000 times that I've looked foolish!)

In-Reply-To: References: Message-ID: <7fde043a-6e11-a5b4-4c57-c2dd81aec45b@aei.ca> Scott, I had a look at the two noted images. The first thing that I noticed was that the mode was set in both cases to wide band FM not narrow band FM. If you are trying to copy ISS packet using WBFM that might be the source of your problem. It could be that the new radio on the ISS has a somewhat lower deviation than the old radio. The second image (Spectravue) does indicate that your receive might be a bit high in frequency. If you are not using your SDR to try and copy the ISS then perhaps you should state what equipment you are in fact using; I may have missed it from an earlier post. I have been having good luck copying the ISS using my FT-817. Sometimes I use a dual band VHF/UHF collinear vertical and sometimes a small yagi, the yagi works better but the vertical still works OK too. I don't adjust for doppler, I just set the FT-817 to 145.825. Doppler on 145.825 for a typical pass is about +/- 3.5 kHz at least according to GPredict. cheers, Graham ve3gtc On 2017-04-24 22:20, Scott wrote: > Hi everybody. > > This is essentially a request for what I believe the scientific folks call > "peer review"... > > I continue to try to understand why none of my equipment has been receiving > the ISS digipeater very well since the switch back to 2 meters, despite the > fact that the same hardware does well on terrestrial packet and in the case > of 145.825 in particular, I have even received packets from PSAT since > re-configuring for VHF reception on my Raspberry Pi / RTL-SDR iGate.

I wasn't concerned with demod or decoding packets on this particular night; but rather to run a wide-band capture with no doppler correction to allow the transmitted signal to paint the doppler curve on my display to identify the center crossing at closest approach. That does a number of things for me like identify the transmitted frequency (at least as received by my hardware), verify my TLE's, and to get a visualization of how much doppler shift is occurring between AOS & LOS. It does interest me quite a bit to try to characterize differences between those who are seeing better performance -vs- those who are not, so you're right on to mention hardware. We can't generalize, but I see "some" evidence since the freq change that the group having better luck might be those with equipment like the FT-817 and the folks using the excellent Kenwood HT's. But it goes without saying that with such a large sample group, a VERY large number of people could step forward with minimal equipment reporting good success as well. From my own testing I can observe that I decode way more packets with an SDRPLay than with a cheap mobile rig or generic RTL-SDR. I know that sounds obvious (that superior hardware gives superior results) but that's not my point... rather that it just "feels" like that wasn't so much the case with the previous 2-meter setup. I could easily be wrong but when it seems like some experimentation might provide some useful info to improve everyone's enjoyment of the resource, I have a hard time leaving it alone! ============================ On Mon, Apr 24, 2017 at 8:33 PM, Graham wrote: > Scott, > > I had a look at the two noted images.

Message-ID: <22b00a75-d04d-38d7-d610-82c95fa36e97@bellsouth.net> I used an Alinco DJ-X11T receiver in SDR mode to record an 80 degree ISS pass at 13:33:53 UTC this morning. The packet signals did appear on the expected frequency given Doppler shift (centered on 145.825 MHz). However, there does appear to be an issue with the packet transmissions. Scott's Dropbox image of the pass over several minutes compressed the packet transmissions to the point that the issue is not visible in his image, but it is quite apparent in my waterfall which only shows about 20 seconds at a time in KGSDR. Namely, the centerlines of all packet transmissions describe a "J" shape, even at AOS and LOS when Doppler should not be noticeable at all. In other words, there is a rapid increase in transmitted frequency at the start of a packet transmission, and this frequency change rate diminishes toward the end of the transmission. This phenomenon could very well cause some receiving systems to fail to decode packets. I tested my system against local terrestrial packet stations just prior to the pass, and the packets show vertical lines in the waterfall, so this is not some systemic issue in my receiving system.

The event is scheduled to begin at approximately 08:52 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between FX0ISS and F8KGY. The contact should be audible over France and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in French. Thionville is a commune in the Moselle department in north-eastern France, close to the Luxembourg border. The city is located on the left bank of the river Moselle. Thionville is well-known for the Steelmaking activity until years 1970, and for the Malbrouck Castle nearby (15th Century). More than 1000 pupils from 11 to 18 attend Helene Boucher High-School in Thionville. The school is preparing students for the "Baccalaur?at Litt?raire, Economique et Scientifique" Some students, aged 15, have preparing their HAM-radio license to be able to use the equipment on D-Day. Other students aged 15, are also working on an educational model project which will allow them to show how to use the equipment necessary to get in touch with ISS, to younger students. These same students would also like to present this educational model and the project itself to compete for "Olympiades de Physique", a prestigious challenge, open to all French high-school students. A scientific club called "Objectif Mars" (Mars Objective) has existed for three years at H?l?ne Boucher high-school. It work's on: The computer programming of self-sufficient robots, The making and the launching of micro-rockets, The making and the use of an astronomical telescope. Getting in touch with ISS is part of the same project "Objectif Mars". Participants will ask as many of the following questions as time allows: 1. Comment les passagers de l'ISS s'arrangent-ils pour leurs cycles de sommeil? 2. Comment r?agit l'horloge biologique face ? la disparition du rep?re jour/nuit? 3. Comment la station ISS parvient-elle ? ?tre autonome en ?lectricit?? 4. Quand vous transpirez apr?s une s?ance de sport, comment vous douchez- vous? 5.

Comment la station ISS et vous-m?mes ?tes affect?s par une ?ruption solaire? 10. Comment la station est-elle prot?g?e contre les rayonnements cosmiques et les vents solaires? 11. Comment faites-vous pour vous soigner en cas de besoin? (maladie, blessure, etc..) 12. Comment fonctionne la centrale inertielle de la station? (angles d'inclinaisons) 13. Quelles sont les sensations lors d'une sortie extra-v?hiculaire? 14. Comment est affect?e l'oreille interne par le manque de pesanteur? (tournis, mal de l'espace) 15. Peut-t-il y avoir des conflits entre vous? Si oui comment les g?rez-vous? 16. Si on vous propose de participer ? une mission vers Mars, le feriez-vous et si oui, pourquoi? 17.

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.

Message-ID: Since I have been using both a Kenwood TH-D72A and other less-than-optimal gear for packet and APRS over the last several years, I decided to do a side-by-side packet decoding test this afternoon during a 38 degree ISS pass at 2048 UTC. Both ground stations were connected via a splitter to the same antenna (an old analog TV antenna at 0 degree elevation and covering all 360 degrees azimuth). Both ground stations also shared the same Pentium dual-core laptop computer for software. The less-than-optimal station included the following: Icom IC-02AT HT Unified Microsystems SCI-6 Sound Card Interface AGWPE UI-View32 The Kenwood TH-D72A was in packet mode and decoding through the latest version of Yet Another APRS Client (YAAC). Both stations were tested prior to the pass on terrestrial APRS with almost identical decoding results. Tuning during the pass was done in 5 kHz increments on both stations (145.830 MHz, 145.825 MHz, 145.820 MHz). Reception during the ISS pass was less than stellar due to local noise, but both stations decoded the same number of packets (13), although they didn't always decode the exact same packets. So even with the non-linear frequency shift noted previously by K4KDR and myself, there does not seem to be any appreciable difference between my ISS packet decoding ability now and any point in the past, even with non-packet hardware. Perhaps a couple of other stations could share their experience in this regard.

I saw that the difference between the two Control Box is the Azimuth Display, that the G-5400B one has on the left and on the right side of the display: 180 S, while the G-5500 one has on the left side of the display: 0 N and on the right side of the display 90 E.

Shouldn't damage the rotator if you use the control box as a drive unit, rather than as an indicator (will be wrong, as the g-5400 is a 360 adnd g5500 is 450). Use a K3NG arduino rotator connected to the aux plug on back as a controller. Can use relays or transistors to key the aux control lines. Do note that K3NG's code needs to be cofigured correctly: I.E. total rotation and center.

They both use a phase shift capacitor for full torque, and also a method of protecting the motor in case it hangs. In the G-5400, the azimuth rotator has the capacitor in the control box, and uses thermal limit switches. The elevation rotator has the capacitor located in the rotator housing, and uses mechanical limit switches. In the G-5500, both units have the capacitor in the rotator, and mechanical limit switches. For completeness, the original Kenpros, which Yaesu acquired, had the capacitors for both in the control boxes. There are reasons why mounting the capacitor remotes is better, but it is much messier to replace, and more likely to fail due to the temperature extremes. 73s, Alan WA4SCA <-----Original Message----- References: <37CA2B76-6AF4-42AF-845F-31C0A6C76682@alice.it> Message-ID: Pic of external mounting G5400 azimuth motor start/run capacitor here: https://www.flickr.com/photos/n3ykf/34151446542/in/dateposted/ Not very difficult to do.

In-Reply-To: References: <02c11a27-ff8b-65d4-7fdc-b89f26c51ab9@bellsouth.net> Message-ID: <7add6e30-afe8-4586-22ef-c8820e45bee2@bellsouth.net> Yes, I can, but I'm not complaining about performance. The point of the TH-D72A vs. IC-02AT test was to see if evidence existed to support the notion that there might be some anomaly with the new ISS APRS system that might explain why some operators (Scott, K4KDR and others apparently) are unable to decode packets now when they could previously, either on 70 cm or 2 m. If my comparison test had come up, say, 13 to 2 packets decoded in favor of the TH-D72A, that would lend credence to the notion that such an anomaly might exist but is masked by the better performance of purpose-built (i.e. designed for packet/APRS) equipment like Kenwood and Yaesu transceivers. When you have a measure of experience with something like ISS APRS reception, it's easy to brush off reports like Scott's and just chalk them up to operator ignorance, operator incompetence, simply forgetting a step or two in a setup process, etc. But Scott is asking for some help (a sanity check), and I was just trying to perform a few independent tests. There are plenty of other operators who could do the same thing. So now the question would seem to turn to things like: What do Scott's station and the others have in common (if anything)? Are they all SDR type stations? If they are SDR stations, are typical SDR stumbling blocks handled properly (offset, center spike at 0 Hz offset, etc.) Are the station components and transmission lines well shielded? Have local interference sources come into existence on or near 145.825 MHz since the ISS was previously on that frequency?

I plan to operate several satellites this time and to concentrate on evening passes when they are available. Equipment will be (as it was on Montserrat in 2015) an IC910H and Arrow. I'll again announce the passes I'll operate here on amsat-bb in advance with updates during the expedition. Callsign will be FJ/N0KV. Satellite QSOs will be uploaded to LOTW either during or immediately after the trip and paper QSLs will be available from N0KV; please provide an SASE. Jim, WD0E AI5P, N0KV, W0ZA and WD0E plan to operate from Pointe Milou, St. Barthelemy Island (IOTA NA-146/Grid Square FK87) from October 17 - 26. Operation will be on 80-10 meters (SSB/CW/RTTY) with satellite operation by WD0E. Conditions may largely limit most activity to 20 meters and down. Operating 160 meters is being considered; however, no antenna option is yet finalized. Satellite operation will take place on several satellites. A satellite and pass schedule will be announced on the AMSAT-bb in advance. Equipment includes three Elecraft K3's and two 500 watt Elecraft amps. Antennas include a SteppIR crank IR vertical for 80-10 meters, a folding hexbeam by Folding Antennas (Germany) on 20-10 meters, LPDA's on 20 and 17 meters and verticals on 30 and 40 meters. Operation will be as continuous as conditions warrant. The Colorado operators have decided to use FJ/N0KV as their callsign while AI5P will be active as FJ/AI5P. FJ/N0KV logs will be updated to LOTW while Rick's logs (FJ/AI5P) will not since he continues to be an analog guy with an actual key and pen/paper log. Paper QSLs will be available from both N0KV and AI5P direct and via the buro. US addressees send SASE; addressees outside the US should send SAE plus $2 for return postage. Use of Club Log is not anticipated. Further information will be published as the trip approaches.

The event is scheduled to begin at approximately 12:02 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between RS0ISS and SX2ISS. The contact should be audible over Greece and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in Greek. The 14th Elementary School is a mid-size school in the centre of Katerini city. It is a three floor building with 16 classrooms established in 1977. Many residents have attended it all these years. It has won prizes and honors in various fields (culture, athletics, etc.) and its graduates have successfully continued their education in a higher level. Teachers' effort is to engage kid's mind in a research for knowledge in various fields like science, technology including space, engineering and arts. For this reason, in the flexible zone program, the school kids are engaged in projects such as an exhibition of their drawings with themes from space and planets, paper handicrafts with related themes, presentations about space exploration and how satellites are staying in orbit. Their activities include visits to the local amateur radio club to find out how telecommunications work. Participants will ask as many of the following questions as time allows: 1. What is your current mission aboard ISS? 2. What age did you first realize that you wanted to become a cosmonaut? 3. What are your thoughts when you look at Greece from space? 4. Are there any debris in Space? 5. How do you brush your teeth? 6. How do you get a shower? 7: How many times did you walk in space? 8. What do you eat and drink in space? 9. How do you have fun in the Space Station? 10. How fast do you travel? 11. How much time do you need to get in to the space suit? 12. How long does it take to get to space? 13. What are your thoughts during your mission? 14. How do you prepare for your space travel? 15. How long do you stay in space for every mission? 16. How many times have you travelled in space? 17. What words describe a man's effort to become a cosmonaut? 18. What does an astronaut feel when he observes the Earth from space?

As per normal, we will switch back to autonomous mode on Sunday pm UTC. 73s Wouter PA3WEG and the FUNcube Team ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Low temperatures give higher freqs!) FUNcube-2 aka FUNcube on UKube The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/EO88 Nayif-1 FUNcube-5EO88 is presently operating in autonomous mode. The transponder isoperational when the satellite is in eclipse, ie the solar panels are NOTbeing illuminated.When the transponder is switched off, the telemetry beacon is on full power,when the transponder is on the beacon it is on low power.The transponder frequencies are:Uplink: 435.045 ? 435.015 MHz LSB (inverting)Downlink: 145.960-145.990 MHz USBTelemetry Tx: 145.940MHzAll FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

You can send frequency updates to it, but not read the frequency data from the radio. The limitation that introduces is you can't use the tuning knob to tune around the passband, you'll have to use the controls in SatPC32 (or other software). 73, Paul, N8HM On Sat, Apr 29, 2017 at 10:50 AM, Dave Mann wrote: > Please help me out with critical comments about receiver sensitivity vis-a-vis the venerable FT-736R and latest 2-m/70-cm all-mode transceivers best suited for AMSAT work. > > Thanks in advance, > Dave N4CVX > > Sent from my iPad > _______________________________________________ > Sent via AMSAT-BB at amsat.org.

I've learned from good advice like that received here to stick with what works best. My two optimized Kenwood TS-830's are good examples of that. Yes the FT-736R has limitations on the CAT instruction set and interfacing.

The FT736R receiver sensitivity is limited by its noise figure, which is about 4 or 5dB at best. By the time you add on a little coax loss you have a receiver which struggles to compete with modern sets. However, having said that the radio is loved by many as a simple receive (masthead) preamp powered directly from the radio can transform its sensitivity. It is still used by many for EME Contesters also like this radio but frequently replace the internal LNA and mixer with one produced by Mutek. www.ssbusa.com/mutek.html I have one here and still use it.

Bought it new. I must have had a lemon as it lost the finals twice. Went back to the factory the first time, got it back and plugged in. Before I even had a chance to enter any frequency on the dial, there was smoke coming out of the top of the radio. Back it when to Yaesu. Yaesu took it back, refunded my money and I bought the Icom (I think 710) on the market back then. Forget the model number, but it was a huge radio. Anyhow... one of the problems I found with the 736R was the power meter. It did not represent anything other than the position of the knob. Instead of indicating what was going out the back door, the meter showed where the knob was positioned. I had the radio out at field day the very first time in 1993 after using it at home for several months and we could not make one contact. I knew how to operate the satellites and knew what I was doing. After an evening of trying, we hooked an SWR meter to the output and found there was nothing going out even though the power meter consistently showed anywhere from full power to low power as the power knob was turned. That is when I sent the radio in the first time. I did not like that design for the power meter. Have no idea if other manufacturer's do the same thing but it is kinda dumb although easier than measuring the output power. I have known many hams that have used the 736R and still use it and have no problems. Just my experience. 73...bruce From AJ9N at aol.com Sat Apr 29 23:38:43 2017 From: AJ9N at aol.com (AJ9N at aol.com) Date: Sat, 29 Apr 2017 19:38:43 -0400 Subject: [amsat-bb] Upcoming ARISS Contact Schedule as of 2017-04-29 23:00 UTC Message-ID: <30cde.1cf9a34.46367e03@aol.com> Upcoming ARISS Contact Schedule as of 2017-04-29 23:00 UTC Quick list of scheduled contacts and events: Lyc?e H?l?ne Boucher, Thionville, France, direct via F8KGY The ISS callsign is presently scheduled to be FX?ISS The scheduled astronaut is Thomas Pesquet KG5FYG Contact was successful: Thu 2017-04-27 08:52:17 UTC 83 deg (***) Orel, Russia, direct via TBD The ISS callsign is presently scheduled to be RS?ISS The scheduled astronaut is Oleg Novitskiy Contact was successful: Sat 2017-04-29 06:05 UTC (***) 14th Elementary School Katerini, Greece, direct via SX2ISS The ISS callsign is presently scheduled to be RS?ISS The scheduled astronaut is Fyodor Yurchikhin RN3FI Contact was successful: Sat 2017-04-29 12:02:10 UTC 69 deg (***) *************** *************************************************************** ARISS is always glad to receive listener reports for the above contacts.

It is time to be creating your shopping list and making your travel plans. Last year, we had 45 people assist with the AMSAT booth at Dayton. We've had a good response so far to our call for volunteers, but we could really use another 10-15 people. The 2017 Hamvention is May 19-21 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 most 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 Steve, n9ip at amsat.org if you can help. Thank you!

The bulk of this episode is an on-location interview with two Raleigh NC area hams who gave a couple of live demonstrations of operating through satellites at the Raleigh Hamfest, April 15, 2017. There?s some banter between hosts David Goldenberg W0DHG and Gary Pearce KN4AQ back in the studio. And toward the end Gary announces a Viewer Challenge that we?ll detail down below. The satellite hams are John Brier KG4AKV and Tucker McGuire W4FS. At 18 years old, Tucker is a relatively new ham who first started operating satellites last summer, and quickly jumped into the deep end. John?s been around longer, but ham radio satellites and space operation captured his focus, too. He produces videos about it on his YouTube channel, Space Comms. Gary talked to John and Tucker after they completed their second demo, and he edited a little of each demo into the interview. There?s video of all of both demonstrations on YouTube. John shot himself operating through ?Saudi-Sat? SO-50, a ?Mode J? FM crossband repeater (145.850 MHz uplink and 436.795 MHz downlink). John used three cameras (including a GoPro on a headband for a unique view). Gary edited the video and put it on the HamRadioNow YouTube channel as an extra bit if video. Gary added two more cameras to the mix to shoot Tucker operating through FO-29, a Japanese satellite that uses a 100 kHz wide ?linear transponder? for mostly SSB and CW (and NO FM, please) between two meters and 70 cm. There?s a few minutes of that demo in this episode, and the whole thing is on John?s Space Comms channel. Watch HRN 316: Look! Up in the Sky!

Over the weekend of April 22-23, 2017, AMSAT-UK members met at the Surrey Space Center to conduct some final testing of the command uplink on the Engineering Model of their payload which will launch on the European Space Agency ESEO mission. The payload, which will transmit 1k2 and 4k8 BPSK telemetry on 145.895 MHz, was set up in the Arthur C Clarke building, with the AMSAT-UK team sending commands on L-band (1260 MHz) from some distance away in the university grounds. A large string of attenuators simulated the path loss to low Earth orbit, while the VHF telemetry confirmed the level of signal received at the ?spacecraft antenna? and that the commands had been executed correctly. With the lab and range testing declared a success, work now begins on constructing the Flight Model hardware. This is due for delivery by the middle of the summer so that it can be integrated into the 50 kg microsat. ESEO is expected to be launched late this year or in the first quarter of 2018.

President Donald Trump -- with daughter Ivanka Trump and astronaut Kate Rubins, KG5FYJ, joining him in the Oval Office -- called Whitson on April 24 to congratulate her on her accomplishment. With Whitson for the call on board the ISS was astronaut Jack Fischer, KG5FYH, who arrived on April 20 for his first mission aboard ISS. "Peggy is a phenomenal role model for young women, and all Americans, who are exploring or participating in STEM education programs and careers," President Trump said. "When I signed the INSPIRE Women Act in February, I did so to ensure more women have access to STEM education and careers, and to ensure America continues to benefit from the contributions of trailblazers like Peggy." Whitson tweeted back, "Thank you, Mr. President, for the great opportunity to highlight the research we are doing up here aboard the space station and beyond!" Last November, Whitson, 57, launched to the ISS on her current mission, with 377 days in space already under her belt, and broke the 534 cumulative-day record in space held by Jeff Williams, KD5TVQ. Whitson became the first woman to command the space station in 2008, and on April 9, she became the first woman to command it twice. She also holds the record for most spacewalks by a female astronaut. "This is an inspirational record Peggy is setting today, and she would be the first to tell you this is a record that's absolutely made to be broken as we advance our knowledge and existence as both Americans and humans," said NASA acting Administrator Robert Lightfoot. This is Whitson's third long-duration stay on board the space station, and her mission was recently extended for another 3 months. Instead of returning to Earth in June as originally planned, Whitson will remain on the ISS until September, returning home with Fischer and Russian cosmonaut Fyodor Yurchikhin, RN3FI. Whitson first served aboard the ISS in 2002 as part of the Expedition 5 crew, was the Expedition 16 commander some 5 years later, and has conducted numerous Amateur Radio on the International Space Station (ARISS) contacts with students on Earth. Whitson has since let her Amateur Radio license lapse.

Operation will be on 80-10 meters (SSB/CW/RTTY) with satellite operation by WD0E. Conditions may largely limit most activity to 20 meters and down. Operating 160 meters is being considered; however, no antenna option is yet finalized. Satellite operation will take place on several satellites. A satellite and pass schedule will be announced on the AMSAT-bb in advance. Equipment includes three Elecraft K3's and two 500 watt Elecraft amps. Antennas include a SteppIR crank IR vertical for 80-10 meters, a folding hexbeam by Folding Antennas (Germany) on 20-10 meters, LPDA's on 20 and 17 meters and verticals on 30 and 40 meters. Operation will be as continuous as conditions warrant. The Colorado operators have decided to use FJ/N0KV as their callsign while AI5P will be active as FJ/AI5P. FJ/N0KV logs will be updated to LOTW while Rick's logs (FJ/AI5P) will not since he continues to be an analog guy with an actual key and pen/paper log.

The radioclub is housed in a scouting building and several scouts came to see what we were doing, soldered a very simple electronic light and showed some real interest in radio. I noticed the ARISS contact with the school in Greece was during this open day so I told the club I would demonstrate this and brought the arrow antenna and a simple handheld radio to show the other amateurs and the visitors that it is possible to hear an astronaut with simple means. The announcement that we were going to hear an astronaut was received with great joy and everybody who was there at the time came out to hear it. After a few (tense) minutes the voice of the astronaut came through and we al heard clear audio. Even some of the radio amateurs were surprised how easy it is to receive signals from space. For as far as I know nobody there understood greek so it was just the idea of hearing an actual astronaut talk that held a crowd.

Software wise this all seems to work. I use a linux setup, with gpredict to track the satellites and calculate doppler shift. The gqrx sdr software can act like a radio that gpredict can control so the receiving frequency is correct. It controls both gqrx as receiver and my ft-857 as transmitter. Hardware wise I bought an rtl-sdr with a small preamp and built the pre-amp into a metal case. This works up to the level where I received AO-73 and received a weak Fox-1A and recorded the pass. But when I pressed the transmit button on the FT-857 (tuned to the 70cm uplink frequency) the receiver (tuned to the 2m downlink frequency) went deaf. Some testing with the arrow antenna and transmitting on 70cm shows the preamp turns deaf on 2 meter. Even without the preamp but with the internal amplifier of the rtl-sdr this happens. Setting the gain to 'automatic' causes a huge drop in signal and takes time to recover. Complete details, experiences, pictures of my setup and details I left out start at https://idefix.net/~koos/newsitem.cgi/1490542545 - has anybody done anything with an rtl-sdr as the receiving side, how do you setup the gain? Is there a solution to fix this? - specific to fox-1a: I am reading somewhat different reports of the downlink and uplink frequencies when I search with google. I hope http://www.amsat.org/?page_id=4690 is right. I did notice the signal is weak even with an amplifier.

AO-85 uplink freq 435.180 ST 67.0hz, dwlink 145.980. 73 Ed PY2RN From: Koos van den Hout To: amsat-bb at amsat.org Sent: Sunday, April 30, 2017 4:57 PM Subject: [amsat-bb] Receiving with an rtl-sdr, desense on transmit I am trying to go full duplex 'on the cheap' by using an rtl-sdr on the receiving side, keeping an ear on the downlink while transmitting. Software wise this all seems to work. I use a linux setup, with gpredict to track the satellites and calculate doppler shift. The gqrx sdr software can act like a radio that gpredict can control so the receiving frequency is correct. It controls both gqrx as receiver and my ft-857 as transmitter. Hardware wise I bought an rtl-sdr with a small preamp and built the pre-amp into a metal case. This works up to the level where I received AO-73 and received a weak Fox-1A and recorded the pass. But when I pressed the transmit button on the FT-857 (tuned to the 70cm uplink frequency) the receiver (tuned to the 2m downlink frequency) went deaf. Some testing with the arrow antenna and transmitting on 70cm shows the preamp turns deaf on 2 meter. Even without the preamp but with the internal amplifier of the rtl-sdr this happens. Setting the gain to 'automatic' causes a huge drop in signal and takes time to recover. Complete details, experiences, pictures of my setup and details I left out start at https://idefix.net/~koos/newsitem.cgi/1490542545 - has anybody done anything with an rtl-sdr as the receiving side, how do ? you setup the gain? Is there a solution to fix this? - specific to fox-1a: I am reading somewhat different reports of the ? downlink and uplink frequencies when I search with google. I hope http://www.amsat.org/?page_id=4690 is right. I did notice the signal is weak even with an amplifier. Thanks for any insights and tips, ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?

I have since switched to using an SDRPlay RSP2, due to its better input filter, Digital resolution, and shielding. One problem with these RTLSDR devices is that they have very broad-banded input filters. Consequently, the transmitter signal, although attenuated, is received by the RTLSDR, causing it to desense. You will need add more filtering to sufficiently attenuate signals outside of the receiver band of interest. 73, Mac / AE5PH On 04/30/2017 02:57 PM, Koos van den Hout wrote: > I am trying to go full duplex 'on the cheap' by using an rtl-sdr on the > receiving side, keeping an ear on the downlink while transmitting. > > Software wise this all seems to work.
