Mike, DK3DWN replied to a post I made yesterday on the amsat-bb mailing list. FAST2 seems to be slightly high in frequency, so I updated my scripts last night and captured the following earlier:

Got up this morning, checked my mheard list and saw an entry I hadn’t seen before for FAST2. Checked my logfiles and I found this (output from listen -t -a):
1200mk: fm FAST2 to BEACON ctl UI pid=F0(Text) len 123 08:20:33

Wow, I wasn’t expecting a full beacon from one of the two FASTRAC satellites, sure, I recently started listening for them, but still, this was a bit unexpected given that I only have an omni-directional antenna, cool though. Now what does it actually mean?
Well, FAST2 is the Amateur Radio callsign for FASTRAC 2 or “Emma” as the satellite is nicknamed. For the rest, I decided to be lazy, Mike, DK3WN has quite a few telemetry decoder programs written, so I downloaded the one for FASTRAC, put it onto a VM, cleaned up my logfile entry a bit and we get.
More detail on what this means is available here. I was wondering about the date and saw this on their facebook page.
The GPS receiver on Emma has not failed, since separation we have had a harder time of commanding her (can do so at very high elevations for a short time) so at the moment one of the microcontrollers that generates part of the beacon… message needs to be reset, which is why the message shows old information. We are in the process of upgrading our groundstation so that we can more easily command Emma and make sure we can reset that microcontroller.
Thanks for your interest and collaboration,
The FASTRAC Team
By the looks of it, the Atmel AVR is still stuck. Hopefully the command team can get it sorted.
(AX.25) Packets from International Space Station.
Nothing overly complicated. I am capturing the output from the mheard command, part of the Linux AX.25 tools package. The AX.25 port (Radio/TNC/Omnidirectional antenna) is listening for packets from the International Space Station and PCSAT. The output updates every 10 minutes and is available here.
