Amateur radio operators used to complain about a noisy signal known as
the Russian woodpecker. It was a staccato noise, somewhat like a
woodpecker's drumming, that would appear on various bands at various
times. Rumor had it that it was an experimental over-the-horizon radar
being developed by the USSR. Wikipedia says it went off the air in
1989.
