Some rough and ready calculations *assuming a LEO* are that PSK needs the TX frequency adjusting every second or so, certainly over the duration of a short PSK transmission no Doppler correction on TX at 29MHz will result in no QSO.
But there's plenty of software which can adjust an HF transmitter so it'll just be a question of user education. Myself I would probably TX with my TS-480 and RX with a TS-2000. PSK-125 may be a better option as it is on 6m when there's an opening (such as today).
