[Elecraft] "K3 VFO A not responding" message

[N5GE]

That sounds like a serial port processing problem in the software and
would indicate that the software can't keep up with the VFO and when
it can't keep up it simply sends a message that the VFO isn't
responding.  That's just my guess.  I could be wrong.

Look at N1MM's manual and see it there is a setting that doesn't pole
the VFO continuously.

My home brew software doesn't attempt to keep up with the VFO, since
usually when I am tuning quickly I'm looking at the rig and the P3's
tracking of the VFO.  The software gets a reading of the Both of the
VFO's states only when the auto update that the K3 VFO sends arrives
in the data stream from the K3.

Disclaimer:

I've never used N1MM and my statement is just one from a retired
software developer.  It is not intended to disparage the quality of
the software.
