[Elecraft] K2 VFO tuning problem on TRN 6 only

[Matt Osborn]

Probably not the problem, but just in case, have you changed the
addresses (dip switch) on all the XVs?

BTW, I'm still waiting for my XV432; you must be a tester.

If I turn up the audio volume, I can hear noise when I move the VFO knob (except in the Lock mode).  The noise is not there when any other band is chosen.  All other TRN channels and HF bands tune normally.
