History
The station used to be known as KYJT "The Jet" and aired a classic rock format. In 2005, it adopted the slogan "Star 100.9" and aired an adult contemporary format.[citation needed] In December 2017, after its annual Christmas music programming, KQSR relaunched as hot adult contemporary station "Mix 100.9".[3]
On December 15, 2023, KQSR flipped to a classic rock-leaning classic hits format as "100.9 The River"; before the change, Yuma had no rock or classic hits stations, whereas the "Mix" hot adult contemporary format directly competed with similarly-formatted KLJZ.[4] Even though KQSR was the second-ranked station in the Yuma market in Eastlan's spring 2025 ratings–trailing only sister station KTTI–El Dorado Broadcasters agreed to sell the stations to K-Love Inc. for $375,000 in November 2025;[5] K-Love reserved the call sign KYLK for KQSR.[6] The sale initiated a wind-down of El Dorado's Yuma operations that also saw the closure of KBLU on February 28, 2026, ahead of a planned mid-March completion of the sale.[7]
