A while back I posted with my long term problem with 2 year old K3 with VFO A tuning freezing or becoming intermittent. Dale and Wayne at Elecraft replied that it could be a bad VFO A optical encoder, since I had tried all the other suggested fixes.
They mailed the encoder, it arrived Saturday am, Sunday pm I installed - and problem solved. Compared to potentiometers, reliability of optical encoders seems way higher but this one was bad. Thanks to Dale and Wayne for the support and my K3 is now tuning as smooth as silk.
