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.
