Sound Card<–>Radio Audio Isolation
#4
Well, I knocked up an interface this afternoon.

That was the easy bit.  Quite soon frustration set in.  First up WSJT-X won't talk to the radio via the CAT cable. (I suspect the cable - cheap Chinese fake prolific job.).  I have what I hope is an FTDI one on the way from the UK.

I am using an external USB sound card. At first it didn't want to play nice, then suddenly around sundown I started getting decodes on 20m.  Pretty exciting, even if I couldn't reply.

Then the PC decided to randomly switch back to using the internal microphone, despite the software wanting to use the USB card.

After mucking around for a couple of hours, the waterfall looks like it is receiving but no more decodes - of course it may be that there was nothing to decode after sunset.
