History
The station signed on the air in 1991 as 94.1 KRIO. In 1998, it changed its call sign to KKMG and moved to its current dial position at 104.1 MHz. Then on September 11, 2002, the call letters switched to KMFR and on April 12, 2004, back to KRIO.

Beginning in 2010, KRIO began simulcasting with KSAH 720. On February 10, 2011, the station changed its call sign to the current KSAH-FM. Beginning in 2012 and continuing for six years, the simulcast was discontinued when KSAH 720 switched to a Spanish-language sports radio format, using ESPN Deportes Radio. When that network was discontinued in 2018, the two stations resumed their simulcast.
