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...
