Huh, history repeating itself. In WWII, the Soviets had a type of land mine that was detonated by playing three specific frequencies over the radio. The Finns figured it out and blasted a polka tune, Säkkijärven polkka, over the radio for four months straight to jam them
That song is special because it contains a large number of unique combinations, so the soviets had a hard time finding a sequence that the song wouldn't set off.
