[Elecraft] K3(s) main oscillator calibration

[w4sc]

I like the zero beat WWV method.  Used it in the Navy to calibrate / PM the 10MHz frequency standards aboard ship. Requires the least amount of test equipment!  If you can receive WWV on 20MHz to calibrate the K3/K3S, all the better,  

Using a frequency counter I would think  0.1Hz resolution and attending accuracy would be in order, plus an accurate time base in the counter, GPS locked,,, or oven-ized, on all the time reference ,,, ect.
