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.
