I can get as far as test the CAT (which klunks the radio and the opens the Test PTT option) but I get no reaction from the Test PTT button. Similarly, if I go back to the program and try "tune," I get a red tune button but the radio does not go into transmit (doing this into a DL, of course). . . . So far this is the only software I've gotten working this morning on any digital stuff. . . . About ready to go back to just being a CW/SSB op. Firm believer that this is a hobby, not a religion. Obviously I do not know the magic incantations for shaking the holy bones over the sacred fires. . . .
