[Elecraft] K3 - Intermittent FP switches

[Don Wilhelm]

Skip,

I suggest you remove the Front Panel assembly and check to see if the 
connector pins on the long connector are tin or gold.  If they are tin, 
then they should be replaced (only the male pins, the mating female is 
already gold).  Elecraft will supply a "kit", I believe at no cost.

Often just removing and replacing the connectors will solve 'strange 
happenings' because the process wipes away oxidation.

If the pins are gold and the behavior continues, contact Elecraft 
support for further action.
