Thanks for pointing out the likely culprits, Don. That's quite a record of repair jobs...it's no wonder you know your way around the K2! I figured it was unlikely to be the encoder but I thought I'd check just in case. 73, Steve VE3SMA On Monday, June 10, 2019, 10:21:10 a.m. EDT, Don

Steve, It is rare to find a faulty encoder. Those encoders are the optical type and almost never fail. I have seen only one failure in the time I was repairing K2s and I have dealt with over 1000 repairs. I would first reflow the soldering on the encoder wires and Front panel U3 as well
