Lyndon Green was known technically as a PR1 (protected repeater station, type 1), comprising a two-level bunker with heavy blast doors.
The bunker was built in 1953.
It is semi-sunken, with the main distribution frame and active equipment on the ground floor and power plant and ventilation system in the basement below ground.”
Lyndon Green is on one of the main trunk telephone (and television) cable routes between London and Birmingham, having a number of important circuits passing through it. It was constructed at a time when all repeaters (amplifiers) used thermionic valves (vacuum tubes), which required far more electrical power than the solid-state amplifiers of today.
