Re: Resonant Feedback
At our college radio station there was one song that turned the transmitter off. Turns out that one of the notes in the song resonated one of the protection relays at the transmitter. We tested this during engineering tests with organ music and let the turntable slow down. We could hear the various notes of the chord vibrating the relay until, poof!, the transmitter turned off.
