[Elecraft] WWV tones and CW reverse?

[JAKidz]

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.
