Have you tried WSJT-X?
I started with Digipan, then moved up to WSJT-X. I found getting the settings to work took the most time.
I installed JS8Call today and have it communicating with my Icom 706MKIIG for CAT, and a signalink as external soundcard interface. It seems to be operating - the waterfall moves and I can change freq, but haven't seen much activity, and have not decoded anything. Might be the settings, or the antenna or the bands..
I used the settings I worked up in WSJT-X for setting up JS8Call.
What problems are you having?
Computer control?
Soundcard interface?
Display?
