I would suggest it's worth the time to swap the VFO A and VFO B
encoder boards. It could be the encoder itself or its contacts to the
front panel board, either of them.
If you take this course, you might want to check the encoder board
contacts on each of them, and also take a look at the
An encoder problem?

The charge was $100.
“$100?” the TV owner questioned. “All you did was plug it in.”
Repairman: “That was $5. The other $95 was for knowing what to do.”

Percussive resets are well-known for finding a general problem area.
They don't localize it, but it's a start.
Good luck with this. An encoder board SOL problem happened to me
about five years ago, and I followed the same advice I gave you (which

I think you are on to something, Matt. On a hunch, I performed a
percussive reset as NASA calls it. I lifted the front on the K3
about an inch and dropped it. The problem went away for now. When it
comes back, I will do as you suggest.
Many thanks to all who replied.

My father, W1BML used to repair TVs and radios after his work was
over back in the 50's in PA, he was the go to guy back then to have
electronics repaired (was W8QXF then W3QXF when the area changed).

’Tis true that doing a reset can cause a problem to go away and is often the

My K3 has developed a problem with the VFO. It is, of course, just

When I turn the VFO knob very slowly, the frequency display follows
