During the Continuation War, the Finnish Army discovered that the retreating Soviets had scattered radio-controlled mines throughout the city of Viipuri. These mines were set off when a three-note chord was played on the frequency the radio was tuned to, causing three tuning forks (of which each mine had an unique combination) to vibrate at once. Once the Army and Yleisradio experts discovered how the mines worked, a Yleisradio mobile transmitter was brought to Viipuri, and Vesterinen's polka (Säkkijärven polkka) was played on the same frequencies the mines used. This operation continued for over three months, until the batteries of the mines were drained.
