[Elecraft] Left hand rotary encoder failure on KX3

[Richard Corfield]

I've tried my KX3 today and noticed that the left hand volume rotary
encoder is not working. Is this a common problem? Is there anything I can
do to try to get it working again?

I'm in the UK and this is a second hand radio, so I can't so easily just
sent it back to Elecraft I don't think.

A firmware restore has given me a non-zero AF Gain setting, but no sidetone
as that is turned low and can't change without this encoder.

Thanks
