[Elecraft] K3 Sticky Power Control

[Grant Youngman]

So it’s probably not the rotary encoder.  My first guess is that it could be related to oxidation on the front panel pins where they plug into the main board.  Or pwr cal maybe? — not sure if that could cause these symptoms.

Others here (likely smarter and better looking) may have a better idea ..
