[Elecraft] K3 Frequency Calibration

[Ray]

Gents
Go to a WWV signal, (5.000000)  on a Good Strong Frequency.
Place the Mode To Upper SSB, Listen to the Beat note Tone Freq,
Now Move the Mode to Lower SSB. Adjust the  Ref. Cal. Osc. until the Beat Note is the Exact Same Freq
On Lower SSB and Upper SSB.   Done

Not having a frequency counter, I went to the alternative method outlined in page 49 of the manual.  I thought I did it all "by the book", but found that when I was done 15-MHz WWV's carrier frequency (determined by zero-beating the carrier) was almost 400 Hz low. Since I wasn't looking for FMT-level accuracy, I went back to WWV and adjusted the REF CAL setting by ear until 15.000 on my RX dial was as close to zero-beat with WWV as I could tell. We'll see how it worked out, but I wonder if I simply have some fundamental misunderstanding of what's involved.  Wouldn't be the first time...
