KFRG is a commercial country music formatted radio station in San Bernardino, California, broadcasting to the Riverside-San Bernardino, California, area. KFRG is believed to be the original "Frog" station under previous owner Keymarket. The brand name has subsequently licensed by Keymarket to dozens of American radio stations. Owned by CBS Radio, its studios are in Colton and the transmitter site for KFRG is north of San Bernardino.HistoryKFRG was previously known was KQLH with a soft adult contemporary format. Due to strong competition from Los Angeles stations KOST and KBIG, KQLH was unable to succeed as an adult contemporary station. On December 25, 1989, KQLH flipped to a country format. The call letters were then changed to KFRG.On August 17, 2006, KFRG became the only country radio station that could be heard in the Los Angeles area by default, as KZLA changed its programming format to rhythmic adult contemporary, until December 1, 2006 when KKGO changed its programming format from adult standards to country to fill a void in the Los Angeles area.
