I was wondering if anyone had tried doing the reference oscillator frequency
calibration for a K2 without the rather troublesome step of accurate
zero-beating by feeding the 500/600 Hz audio tones from WWV/WWVH to a computer
sound card or smart phone spectrum analyzer, or similar program? It's pretty
easy to read these audio frequencies out to a precision of 1 Hz or so using
Spectran or Spectrogram, for example.
Right now, I'm seeing both WWV and WWVH tones (at the same time!) on my
computer screen (within a few Hz of the correct audio frequencies), with the K2
tuned to 15000.24 kHz, so it really ought to be re-calibrated.
Are there any issues with this option, before I start into the whole process?
