Through 19, KFI-FM broadcast its own music programs, separate from KFI (AM).
In the early 1950s, while the audio quality was much better than AM, FM radios were not cheap, there were no AM-FM combination radios yet and stereo broadcasting on FM didn't happen until 1961.
KFI-FM was the first Los Angeles FM station to have its transmitter on Mt. According to an article written by Marvin Collins several years ago, KFI-FM used a General Electric 3 k W Phasotron transmitter, operating with a 2-bay antenna, giving the station an ERP of 10,000 watts.
Anthony sold KECA in 1944 and it moved to 790 k Hz and became KABC.
KFI helped to keep the calm during the dark days of World War II by airing President Franklin D.
KFI (640 k Hz, KFI AM 640) is an AM radio station in Los Angeles, California, owned and operated by i Heart Media. He was an early president of the National Association of Broadcasters and, during his term, oversaw the establishment of the organization's first paid staff.
On November 29, 1944, KFI officials broke ground on Mount Wilson for construction of a new FM and TV transmitting facility.
The station only lasted until 1951 when the owner, Earle C.KFI, 640 k Hz, was an affiliate of the NBC Red Network and KECA, 1430 k Hz, carried programming from the Blue Network.In 1939, KECA moved to 780 k Hz, the frequency of the former KEHE.The frost warnings moved to 7 pm until the late 1970s when they were removed from the schedule.KFI put the first FM station on the air, west of the Mississippi, in August 1941 from Mount Lee. This was what soon became KHJ-FM and is today's KRTH at 101.1 MHz.Later, the 1951 Broadcasting Yearbook listed KFI-FM's power as 16,500 watts.
