[Elecraft] Strange Problem

[Stephen W. Kercel]

Fellow Elecrafters:

I have had a strange problem with my K2, that I've both discussed 
previously on the list and discussed with Scott at Elecraft. The 
problem was that the rotation of the tuning knob would occasionally 
feel rough on my fingertips as it turned, and I heard what I thought 
were clicking sounds whenever I got the rough feeling.

Jim, KA1SU, figured out what was really gong on. The little ring that 
holds the shaft of the encoder in position in the encoder body was 
catching on the fibers of the felt washer behind the tuning knob. The 
clicks were the sound of felt fibers ripping out of the washer, and 
the "roughness" of feel was the abrupt jerk of the tuning knob as the 
fiber pulled free. The felt washer was torn up pretty badly.

How's that for bizarre?
