[BC] RF interference problem

[RON DOT'O SR.]

FM stations won't cause this problem in audio equipment as there is no 
"natural" detector in the components as there is for AM (transistor 
junctions to rectify and detect the RF).  A very strong VHF FM signal MIGHT 
cause buzz or hiss but is very unlikely.
