Mount Lee transmitter complex (Los Angeles)

Named for Don Lee, an L.A. Cadillac dealer in the 1920's. His son Tommy bought the mountain top from Mack Sennett, who wasn't doing too well in the post-silent Hollywood era and really needed the money.
Lee built an FM transmitter in 1940, (the first FM radio west of the Mississippi), initially an "amateur" station with the call letters K45LA. This later became a commercial station known as KHJ (FM-101.1).
Lee had also put up one of America's first television stations here in 1939, W6XAO-TV, which was later known as KTSL, Channel 2 until it was bought out in the early 1950's and became KNXT, (later KCBS).
The U.S. Army took control of the facility on 7 December 1941, and presumably occupied it for the duration of the war.
There have been no commercial stations on Mount Lee for many years. The many antenna arrays festooning the mast are used by various government agencies and public safety and/or relief agencies, such as the Red Cross.
