you probably have a bad tuning coil or other part in the 7.8mhz IF section.

if one of the tuning coils has a broken or corroded wire inside it, the coil can act like a little antenna.

you may have experienced something like this before by touching your fingers to certain sections of a radio's PC board and hearing AM transmissions.

start poking around the IF section and see if you can't isolate which component is causing the problem.

another way to find if you have a bad coil is to try aligning the IF section and see if you have a coil that won't align or acts weird.
