[Elecraft] P3 Not Zeroed

[Bob McGraw K4TAX]

First make sure the radio is correct on all WWV frequencies.   I use CW mode and Auto Spot.  That will get to within 2 Hz or better. Adjust the Ref freq to calibrate. 

Then you can calibrate the P3 to the radio. 

No tuning or listening for zero beat required.
