I have the Digirig Mini and matching cables. I have these settings on the FT-897D:
Menu 38 User-U
My comp sees the PnP USB sound card Com 3
Vara FM: PTT / COM/Com 3/RTS
When I start a Winlink Session I can hear the radio calling out, set to 3 tries. Doesn’t connect. I verified audio contact via FM simplex. The other station hears the same 3 rings. What am I missing?
