Hmmm. Cowboy, I gotta wonder. Could it have gotten the "Golden Screwdriver" treatment before you got it? Somebody who keyed it on AM and turned every slug, looking for a change on the meter needle?
Usually they don't receive too well after that treatment, either.
Trouble is, you need to be able to poke a probe into the radio and take a frequency-counter reading from an internal section to tell if I'm right.
If enough slugs get turned blindly, a legit tech will align the radio from "square one". Most SSB radios can only be aligned right by tapping into internal frequencies with a frequency counter.
If you're set up to do that, great. If not, you need to see somebody who is, from the sound of things.
