[Elecraft] K2 4 MHz Osc Calibration with RWM Moscow [C1]

[Don Wilhelm]

Colin,

While that may work, I have never done it that way and cannot say.
I would choose one of two alternate methods.
1) Use Spectrogram to determine that you are receiving a tone at exactly 
1000 Hz, then proceed with the N6KR method.
2) Tune the signal on another AM receiver - the tone you hear will be 
the modulating tone and you can zero-beat the signal received on the K2 
to that tone.
