Tony,

Hear closely - the KX3 audio shuts down if there is excessive audio 
coming into the mic jack.  I suspect that is what is happening.

Start over on the audio level controls with each of them set to 
mid-range, and then adjust for 4 bars solid with the 5th bar flashing on 
the ALC meter.

Don't forget about the POWER slider in WSJT-X.  It is not a power 
control at all, it is just another audio level control.

73,
Don W3FPR
