KRTH (101.1 FM, K-EARTH 101) is a U.S. Classic Hits radio station located in Los Angeles, California, broadcasting to the Greater Los Angeles Area. Its signal covers an extremely large area, due in part to their antenna location on Mt. Wilson, and can sometimes be heard as far south as San Diego and Tijuana, as far east as Moreno Valley, as far west as Santa Barbara and as far north as Baker, California. The station has studios on Wilshire Boulevard in the Miracle Mile district of Los Angeles.
KRTH broadcasts in the HD (hybrid) format.
KRTH signed on August 11, 1941 as the first FM station in Los Angeles. The station's original call letters were K45LA, broadcasting on 44.5 Megacycles from a tower atop Mount Lee. After World War II, when the FCC mandated the 88-108 Mc. range, the station was moved to 99.7 Mc., and the call letters were changed to KHJ-FM, after its then-sister AM station KHJ. In 1948, KHJ-FM moved yet again to its current broadcast frequency of 101.1 FM, eventually relocating its transmitter to Mount Wilson.
In 1965, when KHJ switched to top-40 format "Boss Radio", they simulcasted on KHJ-FM. From 1968-70, KHJ-FM aired Drake-Chenault's "Hit Parade" format, an automated mix of oldies and current hits. In 1971, the station carried another Drake-Chenault top-40 format, "Solid Gold Rock And Roll."
