PSK31 yes and it is pretty much free form. However one cool thing that Bob indicated last week which I have suspected since last year is that PSAT2 becomes a bent pipe once it detects PSK31. N8URE has sent SSTV and Hellschreiber type waterfall text which was then decoded using Fldigi to PSAT2. The part I suspected which he confirmed last week was that you can also send SSB voice to PSAT2 and theoretically it should send that audio back down. If I misunderstood what Bob said then I take that back but the way I understand it and we have proven that it will send whatever it hears once PSK31 is detected back down over FM.

I’ve been trying to figure out the correct process to engage NO-84 so testing for understanding here.

I can hear occasional PSK-31 in short bursts but have not been able to decode it yet.
I want to make sure I understand what settings to use.
Downlink USB & use FLDigi etc. for decode PSK-31
Receive downlink is USB?
What part of the spectrum Is the downlink typically in (Hz)?
Uplink is on 10 Meters USB also or LSB?
Assuming FLDigi will work PSK-31 fine for Uplink also?
What do I send on uplink, just station ID?
Thanks & look forward to having another bird to play with.
