Hi:

Colin noted that RF can get into a variety of audio circuits.  A case in 
point occurred last summer on vacation.  A small traveler in our party had a 
Teddy Ruxpin.  From time to time the bear would make a ticking sound like a 
metronome.  It took us a while to figure out that this happened when someone 
in the group was talking on their cell phone.
