Captured with the Rodenstock 50mm/4.0 HR Digaron-W lens (@ f/6.3), Phase One IQ4-150 digital back, Cambo 1250 camera (vertically shifted -5mm).

This modest but handsome, art-deco-accented building was built in 1941 to house the transmitter for "KGEI", a commercial shortwave radio broadcast station whose programming could be heard across the Pacific. It shut down in 1994.

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.

250kW is a lot for a radio transmitter right?
I vaguely recall growing up listening to the radio some stations boasting that they were broadcasting with their 100kW tower but I didn't understand what they were saying other than thinking, it's a hundred, that must be a lot 🙃

@[email protected] Yes, though not uncommon for international shortwave broadcasters (who want to achieve maximum coverage for their signals).
