RodB: Thanks. I figured it was 46 or 51 but I really didn't know which.
morzh: I don't really have the equipment for alignment right now since this is outside my usual (old computer) tinkering space, but might be worth looking into in the future. But that's good to know.
Also I had more time to toy around with the radio when it wasn't after 1 am. While there's a hum at lower frequencies (peaking around 600 kHz), it seems to be noise rather than just not getting reception since I can still use the AM transmitter there and it displaces the hum. It just doesn't work as well as it does at higher frequencies.
So for now it seems to work as a radio and I can still route an MP3 player through it to get something other than talk and sports.
Edit: Okay, I realized I have a clock radio with AM to compare with and it gets hum at the same range so I guess there's just local interference. Guess it will be on to fixing the pilot lights.
