[Elecraft] KX3: Intermittent loss of RX sensitivity

[Dick Dievendorff]

I have had this with other radios. It turned out to be a coax connection that cleared up temporarily with application of a bit of power, but then generally got worse. 

One was up the tower...

I picked the KX3 up used, and it needed the VFO B encoder replaced, which I did myself with the help of some advice from Lyle, Roman and Elecraft support (Thanks!!!). This obviously required the disassembly of the KX3. I'm not sure if the sensitivity problem is related to this or not. The encoder works fine. This seems like a "sticky relay" issue. Has anyone experienced this issue and have any suggestions on the cause and a cure?
