AMSAT FoxTelem Version 1.11 Released

I am releasing version 1.11 of FoxTelem. This primarily supports new features needed for GOLF-TEE development and the CubeSatSim. If you are using FoxTelem in the lab or classroom then this release should be installed. It also fixes several bugs that will help with live decoding of AO-95. It is not a mandatory upgrade but it is recommended.

Specifically it addresses the following:

  • Fixes a bug where Costas decoding can stop if audio is being monitored
  • Supports all the latest features needed for the CubeSatSim
  • Better warnings for tracking and Find Signal errors
  • Supports all the latest GOLF-TEE layouts
  • Fixes a bug where strong signals may not be tracked correctly
  • Supports math expressions in telemetry conversions
  • Better handles USB device errors

You can download FoxTelem here:

AMSAT Pacsat Ground Station Version 0.43 Released

I’m releasing an update to the Pacsat Ground Station. This version:

  • Parses the MO-112 FailSafe beacons and saves them for analysis.
  • Fixes a bug where FalconSat-3 telemetry data could not be downloaded from the server
  • Defaults FalconSat-3 to not check Pacsat File Header checksums. This was annoying for partially downloaded files.

You can download it here:
https://www.g0kla.com/pacsat/index.php

[ANS thanks Chris Thompson, G0KLA/AC2CZ, AMSAT Pacsat Ground Station Developer, for the above information]

FalconSat-3 Update

I had sufficient WiFi to check out FalconSat-3 around 1200 UTC 8 July 2021. Thankfully, only the TX had gone off and a reload right now isn’t necessary. If I can make the time, I’ll look over the telemetry logs and see if we had a low voltage trip or something, but not sure.

Users—until further notice, please limit the size of your uploaded files to around 10k or less. Just before the bird went silent, numerous large files were being uploaded and downloaded. I cannot say for sure if this is related to the recent issue, but let’s call it a hunch.

In the meantime, FalconSat-3 is again open for BBS and digipeater use – please limit file upload size to 10K or less.

Long Live PCSAT (NO-44) (and PCSAT-11)

Some (current) APRS Amateur Satellite history:

CONSTRUCTION: For what it is worth, After 20 years, both PCSAT side A and B transponders (digipeaters) remain semi-operational as the longest running student project satellites in space. Further they were built desk-top style using simple off-the-shelf Kantronics KPC-9612 TNC’s and Hamtroncs kit TX/RX boards. All parts are COTS and chips are in sockets. Batteries are AA NiCd’s. There are no CPU’s on board. All command/control/telemetry is just what is inherent in the TNC’s. Only thing we did was replace all electrolytic caps with tantalums. Having no clean room, we just used kem wipes and alcohol to wipe off all the fingerprints and dust before bagging for delivery.

NOTE: No one should be so cavalier if their mission is REAL and costing great amounts of expectations and money. Back then it was just a free ride with no expectations other than student involvement.

SAFE MODE (NOT): The only thing wrong was stupid thinking on the power budget. As our first satellite, we put on dual A/B systems AND additional 9600 baud DUAL UHF backup link receivers so that we had QUAD backup command RX capabilities in case of failures. The problem was we decided that all systems must come up on power-up in order to have access to all the redundant backup reset and command capabilities if needed and (DUH!), if all was OK, we would turn off the unnecessary backup-UHF receivers and un-crossconnect the transmitters.

TOO-COMPLEX LOGON: That is what kills it (on every orbit). If the reason it reset is because of low battery, then the last thing you want is for EVERYTHING to be ON when you are coming into the sun and trying to charge back up. There is not yet enough power to get the command in to command off the unnecessary systems! Further, the commands required a full two-way AX.25 connection requiring 5 packets to exchange the password challenge and password response. All of which fully loaded the cross-connected XMTRs while trying to recover power.

NO CPU or OPERATING SYSTEM: PCSAT had no programmable CPU. Just two-dual-port TNCs and 2 VHF XMTrs and 2 VHF RCVRS, and 2 UHF 9600 baud RCVRS. There was nothing in which to put SMART-safe-mode power-up thinking. Hence the fatal flaw to just power up everything and command later… duh…

WITH LUCK: But luckily, the orbit occasionally has short eclipses and longer sun side (about 1 hour) which gives it enough time to sometimes have enough power to do a few user digipeats. Though after only a few, that usually kills the battery for the rest of the orbit. We long since gave up trying to go through the entire secret logon process to try to turn off the extra UHF receivers, only to have it last another’ 10 minutes or so until the next eclipse and so that is why it just does its thing and sometimes people are successful, or not.

MISSION: Side A of PCSAT (AKA W3ADO-1) remains operational on 145.825 digipeating when power permits. Same for side B which has a digipeater with a 144.39 MHz downlink for use over North America which at the time was thought would be useful for communicating *TO* normal 144.39 travelers who may be traveling outside of range of the terrestrial network for a while.

TODAY (June 8, 2021), one of our sysops tested the side “B” and confirmed it remains operational. That is why you might occasionally see PCSAT-11 in the APRS logs. Although within the rules at the time of launch, in the last decade, the IARU has officially made notice that operation of satellite downlinks in the old 144.30-144.40 range are no longer authorized. Besides, we never came up with a good use of the side B anyway. (Broadcast an APRS message to all North American mobiles, or special traffic to a specific mobile).

Of course, we learned those lessons and had 6 successful follow-on APRS satellites with only the last two (PSAT and PSAT2) had programmable CPUs (BASIC Stamps). See http://aprs.org/sats.html

Upcoming Satellite Operations

Quick Hits:

VP2V/K3TRM: I will be operating from Tortola, BVI as VP2V/K3TRM on July 4-17, 2021. Activity will be on 40-6M SSB & digital, and satellite.

EN57/67: @SeanKutzko KX9X and @Nancy_N9NCY will celebrate Sean’s birthday in the Michigan’s Keweenaw Peninsula July 15-19. Look for them on FM and SSB satellites, with the possibility of some Parks On The Air activity as well. They will also hit EN57/67 on 7/14&19 on the Yooper Rove.

K0JM, Monday, Tuesday, Wednesday (July 12-14) I’ll be on the north shore of Lake Superior. I hope to get in at least one pass in each of the grids: EN36, EN46, EN47, EN48, EN57 and EN58. But this will be holiday style, so no guarantees. Mostly linears, but some FM perhaps.

Major Roves:

WY7AA:

July 11 DN25 daytime passes
July 12 DN27 with a guest Gridmaster hopefully
July 13-16 DN28 holiday style
July 17 DN38 holiday style
July 18 DN47/48 daytime passes
July 21-23 DN54 holiday style
July 25-27 DN64 holiday style
July 30-31 DN63 holiday style

July 11 & 18 will all be planned trips just for Sat passes FM and SSB. I will try to publish passes ahead of time on Twitter and QRZ. The remainder of the trip will be camping in remote areas with little to no internet or Twitter. I will get info out as I can, but I won’t be able to setup skeds ahead of time. Lots of POTA activations on Sats and HF as well.

Call for Nominations – 2021 AMSAT Board of Directors Election

AMSAT solicits nominations for the 2021 AMSAT Board of Directors election, to be held in the third quarter of the year. The seats of the following four incumbent Directors expire in 2021 and will be filled by this year’s election:

Jerry Buxton N0JY
Drew Glasbrenner KO4MA
Patrick Stoddard WD9EWK
Michelle Thompson W5NYV

Further, up to two Alternate Directors may be elected for one-year terms.

A valid nomination for Director must be written and requires either one Member Society or five current individual members in good standing to nominate an AMSAT member. Written nominations, with the nominee’s name, call sign, and contact information, as well as the nominators’ names, call signs, and contact information, should be sent to the AMSAT Secretary:

Jeff Davis, KE9V
1909 S. Batavia Avenue
Muncie, IN 47302-2044
ke9v at amsat.org

A copy should be sent to Executive Vice President Paul Stoetzer, N8HM, at n8hm at amsat.org.

The AMSAT bylaws require that the nomination be written and in the form specified by the Secretary. The Secretary has elected to accept written nomination materials via mail or in electronic form, including e-mail or electronic image of a paper document. Fax transmissions cannot be accepted.

No matter what means are used, petitions MUST be received by the Secretary no later than June 15th. The Secretary will verify the qualifications of candidates and nominating members or Member Societies as petitions are received, and will notify candidates whether their nominations are in order by the end of June.

[ANS thanks Jeff Davis, KE9V, AMSAT Secretary, for the above information]

CHESS CubeSats Will Not Carry Amateur Transponders

Two CHESS CubeSats had been planned to carry amateur radio linear transponders, however, it was announced on June 10, 2021, there will not be any amateur payload on the satellites.

A translation of the press release reads:

The CHESS project management, due to funding constraints, had to move the project towards a commercial cubesat platform. Space is scarce on this new platform to accommodate another payload. Subsequently, there is no longer an opportunity to carry a ham radio transponder on board.

The CHESS project management has correctly decided not to use frequencies in the amateur satellite service and to use earth exploration or experimental UHF- and X- band frequencies.

The ham community, who assured the funding of the transponder, is very disappointed by this decision, but must accept it.

Such projects always carry risks of one partner changing its mind. That is what happened here.

Many thanks to all who have actively supported the transponder project, especially the AMSAT-UK and AMSAT-NL team.

ARISS Offers More Fun to ARRL/AMSAT Field Day Operators

Amateur Radio on the International Space Station (ARISS) has decided to keep its ARISS InterOperable Radio System (IORS) in crossband repeater mode until after ARRL Field Day ends. The IORS ham station is located in the Columbus Module of the International Space Station.

ARRL Hq Contest Program Manager Paul Bourque, N1SFE, has confirmed that successful radio contacts made through the ARISS IORS, in crossband repeater mode, will count for an ARRL Field Day QSO point, but also for Field Day bonus points! Another fun opportunity for points. Don’t forget the rule limiting stations to 1 QSO per any single channel FM satellite. On-orbit astronauts always have very busy schedules, but if a voice contact were to be made with them, it would count for QSO credit but not for satellite bonus points. Only an ARISS crossband repeater QSO qualifies for the bonus. Crossband repeater contacts are also valid for AMSAT Field Day for satellite operations, held concurrently with the ARRL event.

Frequencies for ARISS crossband repeater operation are as follows: 145.990 MHz up, 67 Hz tone and 437.800 MHz down. If you haven’t used the ISS repeater yet, be sure to practice with it before Field Day (June 26-27, 2021). These contacts can be tricky, but hams can practice right now…can you do it?

ARISS had planned a mode switch to APRS packet during the second week of June. Now, ARISS is targeting the switch by the astronauts to packet after the first ARISS school contact following ARRL Field Day. In more news for ARISS supporters: the astronauts will power down the ARISS radio station during USA spacewalks on June 16 and June 20, 2021.

FUNcube Dongle Stock Update

Over the past month it’s proven difficult to keep stock, but we look forward to having stock ready within the next few days.

During the pandemic, we’ve seen a significant uptick in sales of the FUNcube Dongle, and this trend continues.

While we’ve managed to maintain stock for most of the past twelve months, it’s not been easy, and for the last month or so unfortunately we’ve been running on empty. The perfect storm combination of increased demand, logistics delays due to the pandemic, and more recently the global parts shortages, have all impacted our ability to maintain stock.

On June 10th, it was announced that a limited stock was available for purchase at https://funcubedongle.3dcartstores.com/checkout_one.asp

[ANS thanks the FUNcube Dongle Team for the above information]

Changes to AMSAT TLE Distribution for June 10, 2021

Rather than continue to send a “No amateur satellite additions or deletions…” report each week, I have decided to send an update message only when an addition or deletion has actually occurred. It seems a waste of bulletin space to send a message when there is really no new news.

Please assume that if there is no change message, that means no additions or deletions have occurred.
