KFI-FM was a short-lived FM broadcasting station, licensed to Los Angeles, California. It was the first station with a transmitter located on Mount Wilson. The station began test programs in 1946 and only lasted until 1951, when the owner, Earle C. Anthony, decided to shut down operations and return the license to the Federal Communications Commission (FCC). This was because relatively few persons had FM receivers, and owners saw a limited future for FM operations.
