Radio KRFX-FM (The Fox Classic Rock)

KRFX (103.5 FM) is a classic rock station based in Denver, Colorado. The Clear Channel Communications outlet broadcasts with an ERP of 100 kW.

The station signed on the air in 1960 as KOA-FM with a MOR and later a Beautiful music format. The radio station was co-owned with KOA-TV (Channel 4). Studios were located at 1044 Lincoln Street. In 1968 KOA Radio and TV were purchased by General Electric Broadcasting. By 1974 KOA-FM would flip to Top 40 as KOAQ "Q103," where it would enjoy a successful run and become one of Denver's top-rated stations during the early 1980s. Jack Regan was the station's long-time program director and morning DJ. Alan Sledge was music director, and held down the mid-day shift. He later added assistant PD duties. In late 1983 General Electric sold KOA and KOAQ to Belo Corporation of Dallas for $22 million. Lee Larson was selected as the new General Manager. He came to Denver from KLOS in Los Angeles. In 1987 Jacor Communications purchased KOA/KOAQ for $24 million. After nearly 14 years playing Top 40 or Contemporary Hit Rock, on January 18, 1989 they would flip formats to Classic Rock and adopt the KRFX call letters, becoming 103.5 The Fox. The station continues as the flagship station for Clear Channel's "The Fox" radio station brand.
