[Elecraft] K3 No. 8527, CMP/PWR-Control not responding

[Thomas Kluge]

Hi Arne,

A few years ago I had an issue with one of the push buttons at one of
the encoders (K3, SN #1160). This problem resulted in a complete mix-up 
of the function assignments of almost all buttons in the front panel -
so I had to repair it. I decided to exchange all 4 encoders - because
the types were changed in the meantime and the push feeling is
different. As already written in an other comment: It was not really
fun and not so easy. And the end I was quite happy when I powered it up
and everything was working again (and nothing else got broken during
the repair)... You may have already the latest encoder revision - in
this case it's "only" one to replace...
The following web page was quite useful:
