I've been reading this list for a while, decided it's about time I posted something. I attempted to decode the Fox-1A telemetry on 2 passes over Arizona today (approx. 0130 and 0300 UTC) using my Kenwood TS-2000 without success. I configured it for 9600 packet operation, monitored the audio out of ACC2 connector and could see over 20 Khz of audio bandwidth using software based audio spectrum analyzer. Audio response looked good from 0 to 20 KHz so I thought I would be good to go. Nope. I fed audio into 2 different sound card devices - one being the RigBlastger Advantage set to 48 KHz sample rate and the other audio device being my Laptop's built in sound card mic input set to 48K and 96K on different attempts. Audio levels were adjusted so as not to be excessive and sounded clean when played back through the speaker.
When attempting to decode, I could see a very nice eye pattern in the telemetry decode software but the data square waves were pointy looking as if some high frequency filtering was being applied to them. I' not conclusively saying the TS-2000 won't work but I did everything right and tested as thoroughly as possible prior to the actual satellite passes with no success. I'll try again and see if I missed something and report back.
What DID work for me was decoding the signal via SDR. In this case It was an RTL-SDR dongle in direct sampling mode connected to the 10.695 Mhz IF of the TS-2000. HDSDR was used with output bandwidth set to 96 Khz. Audio was piped to Fox telemetry decoder via VB Virtual Audio Cable software.
