KX3 sudden total audio loss

Bill Frantz
During Field Day, my KX3 was running SSB in the GOTA station.
All of a sudden, it lost all audio output, both speaker and
phone. A normal shutdown and restart restored the audio. Does
anyone have any idea what might have happened. (Getting it
working was more important than collection debugging information.)

Could be, but the radio was run from a 95AH lead-acid battery
with solar panel charger and it has internal betteries which
will carry it over a loss of external power.

The charge controller was manual as the electronic one was
making too much RF noise. They monitored the voltage and plugged
in the solar panels when the battery got low and unplugged them
when it got high.

Someone could have kicked the wires though.
