[Elecraft] K3 front panel encoders

[Olli Tuppurainen]

Has anyone figured out how to clean or fix front panel encoders  (SHIFT/LO ,
HI /WIDTH) ?  These cheap ( ~ 0.5$  encoders ) in my K3 has always been
quite " jumpy " i.e.  value jumps up and down in random steps . Also the"
feeling " is not what you would expect form rig in this price range.

Similar issue was in FT-1000MP RIT encoder in 90s . Dust got inside the
optical encoder and turning RIT knob jumped frequency steps quite randomly.
