[Elecraft] K3 - Faulty VFO B encoder

It's a faulty encoder - I had two of them go bad with these same symptoms. Talk to the guys at support at elecraft.com and they will replace it.

I have a K3 SN 1553 

When I first power up the K3 the VFO B works correctly. 

After about 1 minute it starts to get eratic and then stops working completly. 

I have re-loaded the latest (non Beta) Firmware. 

I checked to to see that the VFO B encoder is properly seated to the connector. 

Seems like a temperature related problem. FP temp is normal 27 C 

Has anyone seen a similar problem or have any hints where to start troubleshooting?
