Set the band and the tune digits to your favorite AM stations frequency (say
1240 or whatever). Turn the PTO shaft by hand until you hear your station.
If you get all the way to one end with nothing head, go the other direction.
You will also hear the noise level peak up when you're more or less
synchronized. Be careful not to turn it past its stops however. It's no
big deal, I have to do this every time I open mine up.
