Restored 42-321
#14

Well the reception is nice and clear all up and down the dial. It's just that everything is about 30khz high on the dial. I've been looking over the schematic, and thinking about how it works, and I think I could probably do a very light tweak on the trimmer to the oscillator circuit and move the entire band down a small bit. Shouldn't have any reason to screw around with anything else at this point, since otherwise reception is pretty ideal. Should really even need a sig gen for that, as I'm not going far, the radio will be in tune with itself, and for all I know - I'm putting it right back where it's supposed to be.

I'll mark it first. It'll either work or it won't.
