I must have, but I was suggesting the same thing, a signal generator set on the IF frequency is all that is required to align AM radio IF's to peak them, it doesn't even need to be modulated if you look at the DC out of the detector. I was not suggesting not using a signal generator, just that most of the time a sweep of the frequencies around the center IF frequency was not needed for radios (unless you have an FM detector), so maybe you missed my point?
