    Possibly the earliest true application of negative feedback in RF circuits was Tuska's Superdyne, which had an RF circuit with the familiar tickler coil upside down. In 1923, Tuska and Robert Miner developed a modification of the original regeneration circuit which was called the "Superdyne". The pair had the idea of reversing the regeneration to squelch oscillations in the circuit.
