John,
The 'proper' answer depends on what you consider 'zero-beat' to be. In CW
mode, you would want to hear the WWV carrier at your chosen sidetone pitch
for a real 'zero-beat' setting - AND the displayed frequency will be offset
by the sidetone pitch amount.
If you are using SSB, there is no offset, but in SSB mode, zero beat will
be heard with the carrier at zero frequency (which neither your ears or the
K2 audio can hear).
I believe it is better and easier to listen for the 500 and 600 Hz tones
transmitted by WWV to assure exact zero beat. I use Spectrogram to tell me
when I have tuned correctly to zero WWV - the displayed peak will be either
at 500 or 600 Hz depending on which minute it is (can you tell I don't have
the gift of perfect pitch? <G>).
Take a look at the K2 dial calibration article on my website
www.qsl.net/w3fpr for more detailed information on setting the reference
oscillator.

Holiday Greetings:
When a K2 is set to zerobeat the 10 Mhz WWV carrier, should the
pitch of the WWV tones not change when toggling between CW and CW
reverse in CW mode or between USB and LSB as toggled by CW reverse? And,
when the pitch does not change, the difference between the frequency
readout (10000.14) and 10000.00 is how much lower I need to set C22?
Thanks,
John, K7JG.
