Yes what Tom and Scott said is what I do and is the correct way of working NO-84. You cannot just tune the 10m uplink like you would a linear transponder with SatPc32. It will make the PSK31 signal on the transponder undecodeable. The only real way to work it is with Doppler PSK. My setup consists of a FT-847 on the 70cm downlink, with SatPC32 correcting the doppler on the downlink which by the way I have no issues with. Then I have my FT-950 doing the uplinking on 10m (I use the FT-847 for VHF/UHF/Sat Only and FT-950 for HF only). I use a homebrew dipole that is actually for 40/80m but it tunes up on 10 meters just fine and works well for the uplink on NO-84. I then use FLdigi to decode the PSK31 signals as FLDigi allows multi-decoding for PSK31 which allows me to decode multiple signals in the passband at once. And of course I use DopplerPSK for the generation and correction of the PSK31 signal. Hope this helps. Unfortunately there is not a lot of activity on the PSK31 transponder but I hope that changes with the upcoming launch with Psat-2.
