What’s the version of your wsjt-x and is it on macOS? I noticed a weird bug that wsjt-x v2.7.0 on macOS can deafen qmx every time it transmits or changes the band. Entering the menu then exit restores the audio. This happens only if you select QCX/QDX or QMX for the radio type. Kenwood TS480 works fine.?
