Ken,

I don't have my rig anymore, so I can't verify 100
percent for sure your question regarding the step on
page 76. I don't remember what all is involved with
that and I never did it. Perhaps one of the other
members could advise.

Your problem sounds just like the master oscillator is
slightly off, and I would go ahead and perform the
oscillator calibration against WWV, it's quick and
simple. From what you describe, I think that may cure
your problem.
