[Elecraft] KX-1 Glitch

[Don Wilhelm]

Scott,

I suspect it is the encoder and not the firmware.  Every instance of 
that behavior I have seen is cured by replacing the encoder (and I have 
repaired a lot of KX1s.
If you do not have good desoldering tools, cut the pins of the encoder 
close to the body and then you can 'rock' the 2 securing tabs out.  
Remove the remaining pins one at a time.  Clean up with solder wick and 
if there is solder remaining in the holes, heat the solder pad and push 
it out with a wooden toothpick or stainless steel needle.

BTW - the model designation on Elecraft products does not have a dash in 
it.  it is "KX1", not "KX-1".
