[Elecraft] K2 Tuning knob resistance to tight

[Don Wilhelm]

Sam,

That happens when some of the fuzz 'strings' from the felt washer gets 
caught up in the slot on the encoder shaft.
Try to get it out with the tip of a knife or a needle, and believe me, 
it is not an easy task.  Worst case, if you can't get it out, you may 
have to replace the encoder.  Use a new felt washer in any case.
