[R-390] Intermittent

[LEE BAHR]

I have no idea what "broadcast" means.  If you mean AM broadcast stations 
are coming in on frequencies other then their assigned frequency,  I would 
suspect you have a poor grounding somewhere in the radio or in the antenna 
that is acting as a diode and rectifying the AM broadcast station.  All 
radio transmitters "broadcast" so your terminology is too vague to define 
your problem.
