... This reference signal is then sent to a phase comparator which controls a voltage controlled oscillator (VCO) which produces a 61.44 kHz output frequency. This output is divided down to 60 Hz and feed back to the phase comparator to lock in the frequency. This frequency lock provides great immunity ...

Battle of the Beams
The Battle of the Beams was a period early in the Second World War when bombers of the German Air Force (Luftwaffe) used a number of increasingly accurate systems of radio navigation, mainly developed by Johannes Plendl, for night bombing in the United Kingdom. British scientific intelligence at the Air Ministry fought back with a variety of their own increasingly effective means, involving jamming and distortion of the radio waves. The period ended when the Wehrmacht moved their forces to the East in May 1941, in preparation for the attack on the Soviet Union.
