KGEI was a 250KW commercial shortwave international radio broadcast station. Originally constructed, owned and operated by General Electric, the station opened in 1939 on San Francisco’s Treasure Island. In 1941, it moved to a permanent site in Redwood City. This building housed the transmitter and control facilities; the exterior walls are three feet thick, to better resist any WW II enemy bombings. At the time, KGEI was the only US broadcast station capable of reaching across the Pacific.
