History

The station signed on the air on July 18, 1972 (1972-07-18).^[6] The original call sign was KILA and the station broadcast on 95.5 FM. Its city of license was Henderson. It has always had a Christian radio format. It was a non-commercial station but it broadcast on a commercial frequency.

KILA switched frequencies on August 8, 1985, going from the commercial section of the FM dial to the section reserved for non-commercial stations. At that point, it began broadcasting on 90.5 FM with Las Vegas as its city of license.^[7] The programming became known as "Sounds of the Spirit Radio" with management adding a chain of rebroadcasting stations and FM translators around the Western United States. Reflecting its Sounds of the Spirit Radio name, KILA switched its call letters to KSOS in 2005.
