[Elecraft] K3: VFO A Tuning Freeze problems

[Stan Gibbs]

John,

The disassembly is pretty straightforward. Though, if you didn't build your K3, it might seem a bit more daunting. The process is just about like installing the sub-receiver in an already built K3. 

I would expect that Dale would have checked the encoder-socket integrity when he had it on the bench. 

73,
Stan

The shack is in the basement, pretty cool operating conditions and neither time did the failure occur during a long period of contest operating, so the thinking was the board seating issue, not the temperature sensitivity. But, I'll see what Elecraft comes back with.
