FM radio interference in Marshall 100w 2203 head My friend's home studio is situated about 500 feet from a tower that broadcasts a local FM radio station. Although other equipment in the studio rarely picks up the reception, my Marshall amp seems to really like it. I've had my amp there for the past 3 years, & the radio reception seems to have gotten worse. Even when plugging straight into the amp, you can make the radio louder by moving the guitar & cord.     I'm not sure if the station has increased broadcast power recently, or if something in my amp is going South, making radio reception more audible.     Any clues before bringing my amp to the shop?     Like I said, the sound of the radio has always been there, & is more pronounced when using a string of boost boxes, but I just want to make sure it's not something with my amp. This only happens at his place, no where else.     Thanks in advance,   Steve
