[Elecraft] K3 freq goes wonky

[Don Wilhelm]

Old synth boards or new?

First thing I would suggest is to turn the manual to the Calibration 
Procedures and if you have the old synthesizers, do the Synthesizer 
Calibration, followed by the Reference Oscillator calibration.  If you 
have the new synths, then skip directly to the Reference Oscillator 
calibration (the new synths do not need calibration).

I am not certain that will fix it, but it certainly can do no harm. 
Periodically checking those calibrations is good for the "annual 
physical" of your K3.

I wouldn't be able to hear anyone on frequency. If I tuned up and down they continued to sound like they were off frequency. This only happens between 14.272 and 14.285
