<We all know that AM broadcast radio fades when you drive under a bridge but FM doesn't tend to nearly as much. Why is this?> I'll leave the real answer to someone else, but thought readers might enjoy an anecdote on the subject. The following paraphrased letter to the editor appeared in Radio Electronics magazine in the mid-sixties: "When I drive through a tunnel, FM is okay, but all AM stations suddenly vanish. What should I do?" The editor at the time (whom I believe was the same guy that edits Popular Communications today) replied: "Stay away from tunnels! You're a menace to the entire AM broadcast industry!"
