[Elecraft] Why is my K3 off frequency?

[Grant Youngman]

The other option if you don’t want to go through a REF CAL, is to simply tune to the NCS. Use the dial display to get close, and then, like the old days, ignore it and tune a few Hz until the NCS sounds right.

But, Wayne published a procedure using WWV that will get you within 1 Hz at whatever WWV frequency you choose.  It used to be on the Elecraft web site but I can't find it now, maybe he'll speak up.  It's simple but you must go slowly.  Set the display to WWV's freq at the 1 Hz display precision, select CONFIG->REF CAL, and adjust the REF CAL frequency for exact ZB.  While in REF CAL you'll see a number like
