XW-2D and MSK144
by Wilson C 13 Jul '21

13 Jul '21

With XW-2D operating in short 2 second bursts and then being off for around 5 secs, would QRP MSK144 transmissions work if the transmit/receive time is reduced down to 5 secs? I'm aware that digital modes have been tried before and are hazardous to satellite health if the power levels are too high, hence the requirement for low power. It seems a shame to have a satellite up there that is working (kind of) but not utilised . Wil - G6WQN

Re: Odd issue with CAS-4A & B
by Wilson Convery 13 Jul '21

13 Jul '21

Hi their Frank. I have seen this behaviour on the CAS 4 satellites. I use Gpredict and had to modify the code so that I could retune the transmitter to get the down link where it should be and then re-lock the Tx and Rx frequencies so that I can tune around. I just assumed that either the onboard rx or tx had drifted slightly and this was "normal". 73 Wil - G6WQN

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 thisvaround 1200 UTC 8 July 2021. Thankfully, only the TX had gone off and a reload right now isn't necessary.vIf 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.

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 followon APRS satellites with only the last two (PSAT and PSAT2) had programmable CPUs (BASIC Stamps).

Odd issue with CAS-4A & B
by wa2ndv＠gmail.com 10 Jul '21

10 Jul '21

I am having issues related to doppler on the uplink for these two sats. Its just started the past few days. While I am tracking the beacon freq and QSO's just fine on receive the required transmit frequency seems to be anywhere from -3 to -1 Khz from published center and it is moving throughout the pass, but does not appear to be in a linear fashion ( this in addition to normal doppler correction being applied during the pass ) This issue is not seen on RS-44 or PO-101. I'm waiting for some good XW passes to test further. Nasabare TLE's are up to date and compare closely to Kelso's TLE's. Anyway, just wondering if anyone else is noticing this ? Thanks 73 Frank WA2NDV FN30

TH-D72 Programming Files -- RT Systems
by Les Rayburn 10 Jul '21

10 Jul '21

Very interested in working the APRS satellites using my Kenwood TH-D72, but repeated efforts to correctly program the radio are proving frustrating. Wondering if anyone has a fully programmed TH-D72 that works the APRS birds reliably who might be willing to share their programming file? It’s always easier for me to modify an existing file than to start from scratch. I use both the Kenwood software and the RT Systems (which I much prefer) software to program the rig. Thanks in advance for any assistance. 73, Les Rayburn, N1LF Maylene, AL EM63nf AMSAT #38965, ARRL Life Member, CVHS Life Member, SVHF Member Powered by Mailbutler <https://www.mailbutler.io/?utm_source=watermark&utm_medium=email&utm_campai…>, the email extension that does it all

Long Live PCSAT (NO44) (and PCSAT-11)
by Robert Bruninga 08 Jul '21

08 Jul '21

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 tantilums. 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 LOGGON: 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 unnecewssary 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 thinkinng. 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, 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 are no longer authorized. Besides, we never came up with a good use of the side B anyway. (Broqdcast 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 followon APRS satellites with only the last two (PSAT and PSAT2) had programmable CPUs. (Basic Stamps).

Falconsat-3 again open (users please read)
by Mark L. Hammond 08 Jul '21

08 Jul '21

Hello Folks, I had sufficient wifi to check out Falconsat-3 this morning around 1200utc 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. 73, Mark L. Hammond [N8MH] AMSAT Director and Command Station

Hi, KC1DKY is the only K2H sat op and he is FM only and has been very busy. It's possible he will be able to work some passes tonight after he gets off work. Please don't email him for info. He has already gotten lots of emails. Next year hopefully we will have more ops. Good luck and hope everyone had fun. We do have at least a couple clean sweeps on sats which is great! 73, John Brier KG4AKV
