I just upgraded to WSJT 1.7 after installing an Intel NUC as my PC. I transferred the same config from the original PC. Each time the radio attempts to go into transmit, the manually set DIGU mode reverts to USB. Was there a change in the latest version of WSJT? The other strange thing is that the CAT commands pass the check, but PTT isn't working and the PTT logo turns RED when I try to check it. Reconnected the old PC, using the same settings and PTT works fine.
