I think the only thing you need to do is figure out why the interface
isn't keying the radio.
Since you have Digipan on your pc, in the configuration menu, under
soundcards, select the USB sound device for both RX and TX. Also under
the configuration/serial ports menu, select "none". Press f9 and the
radio should key and the psk tones transmitted
If this works, then your RTTY problems are in the MMTTY settings. If
it doesn't key in Digipan, then the problem is probably in the
interface. Not installed, connected, or adjusted right.
MMTTY only does RTTY and Digipan does PSK. You can try the trial
version of MixW which John uses. It is multimode, but I never got it
working here. Until you get the hardware figured out, you might want to
hold off on any software that has a trial period, since you can't take
full advantage of it. The cd that came with the SL may have had some
other software on it.
BTW, I stick to RTTY and haven't done any psk in years, so of course
I'm an expert.
If need be, find the fuse on the 480 and light it.
