I run the FT 817D and FT 450D here on ALL digital modes,
both use the same SignalLink I/O cable and patch headder.
My PSK 31 software is DigiPan 2004, before DigiPan was G3PLX. Yes tried ALL the others, $$ and free on win XP thru win 10, always came back to DigiPan. Only drawback .. lousy logger .. history lQQkup is great but field and format just awful, N1MM+ solved all my problems. N1MM+ is also the best thing that ever happened to Field Day.
