KOMO 50 kW Transmitter
Vashon Island, Washington
KOMO
increased its power to 50 kW in 1948, inaugurating this new transmitter
plant on Vashon Island, located in the Puget Sound Southwest of
Seattle. The central part of the main floor contained the
transmitter. The left wing contained an operator's bunk room,
coffee kitchen and tube storage; the right wing held the supervisor's
office and laboratory. The full basement contained a double
garage, transmitter blowers, water-cooling equipment for the auxiliary
5 kW transmitter, and general storage. The antenna system
consisted of three 500 ft. half-wave towers.
This was
KOMO's 50 kW transmitter installation. The RCA BTA-50F
transmitter is at left, with the antenna phasor and monitoring panel at

transmitter and audio controls. A concrete vault behind the
transmitter contained the large transformers and reactors, and a dual
air cooling system was located in the basement.
