I don't want to hijack this thread, but let me clarify: FSK does sort of
work with DM780 when using FSK RTTY on my Icom using the USB port for
PTT and the serial port for the FSK line. What happens is that when you
send the command to switch from transmit to receive, there is a fairly
lengthy delay of several seconds. I have tried pretty much every
configuration combination within DM780 and it just won't work and this
has been verified by Mike WA9PIE. The problem is that Rick W4PC will not
spoil his pristine code with the same "kluge" programming techniques
(his words, not mine) that Makoto Mor*i* uses for MMTTY. But that's OK
since I rarely do "casual" RTTY any more so I don't really need DM780
for that. If I am seriously chasing DX I use MMTTY and for contesting I
use N1MM+.
Now back to our regularly scheduled thread.
