[Elecraft] K3: VFO A Tuning Freeze problems

[John K3TN]

Back in March, VFO A on my 2 month old K3 froze up. Back to Elecraft for
about 6 weeks, but the shipping seemed to cure the problem before it got
there, and it worked fine when I got it back - until last night.
Turning VFO A knob causes display to flicker last digit but not QSY. Using
RIT knob will change VFO frequency and display, VFO B knob changes VFO B,
computer control will QSY both VFOs.

Elecraft had mentioned maybe computer control hangup on my end was the
problem, but disconnected computer and serial cable from K3 and restart -
same problem. Elecraft had also mentioned could be a board seating problem,
and since I was annoyed at this unreliable K3, I did the tried and true "one
inch drop on desk" test - which cured the problem, for now anyway.

I've emailed Elecraft support and I guess this time I'll open the K3 up to
reseat the boards (vs. wait out Elecrafts 4-6 week repair backlog) but
figured I'd check if anyone else has seen the same problem with any other
potential solution.
