All, I just tried Wayne's procedure and it worked great. My first measurement showed my VFO to be well below my BFO. It turned out that after 3 itterations I had turned my VFO up to about 5 Hz below my last BFO reading and the BFO had not changed. Everything is now on the money. I think that this one is a winner so put it on the list in the manual. Fran
