Speaking of zero beating, why not get an AM receiver tuned to WWV and
zero beat the tone from the AM receiver to the SSB receiver? That way
you can get within fractions of 1 Hz and it's a lot easier than watching
a computer screen.
I found that I couldn't get the K2 spot on because of the calibration
procedure. I got it darn close, though.

Michael and all,
Yes, because the K2 has independent BFO adjustments for USB and LSB you must
know that both BFOs have been properly set before you can do 'tone matching'
to determine the correct dial setting. It IS a good method to verify that
one has achieved correct calibration, but if the dial calibration is
suspect, attempting to get it correct by matching the LSB/USB tones may
prove to be an exercise in frustration.
If you need to set WWV right on (as when using it to set the reference
oscillator with the N6KR method), I recommend using Spectrogram to view the
frequency of the transmitted tones - they will alternate between 500 and 600
Hz in alternate minutes. See the dial calibration article on my webpage
www.qsl.net/w3fpr for more detailed information.

I've found that using the frequency calibration method in which you
switch
between LSB/USB when monitoring the tone (tuning for the point at which
there is the least difference in the WWV tone between LSB and USB) on WWV
at
15 or 20 MHz works very well on my Kenwood TS-930S. Given the fact that
the
K2 has independent BFO settings for LSB/USB, can this method be accurately
used to check the K2's display frequency against WWV?
Thanks, Michael N9BDF
