I think it's a great idea. I suspect there will, indeed, be some Doppler challenges.
Although, I wonder.... How would Doppler's impact on PSK-31 be different from, say, SSTV? I ask because the SSTV schedules on AO-51 have been pleasantly surprising to me, in terms of the quality of image I was getting.

We are considering an HF transponder for our next long range CUBESAT mission planning. It can have three modes:
- APRS 1200 baud for command and control and APRS on 145.825
- PSK-31 multi-user SSB uplink on 29 MHz and FM down link on
145.825 3) 29 MHz uplink and 24 MHz downlink SSB transponder
We will welcome someone in the AMSAT community that wants to contribute to mission 3, the HF transponder. We tried the #2 PSK-31 mission on PCSAT2 and RAFT, both failed due to HF antenna deployment problems. Now we are going to try again...
