From March 15, 2010 until November 25, 2010, KSPA aired a talk radio format. From 2002 until March 2010, KSPA aired an adult standards format, known as The SPA, which from February 1, 2007 until March 15, 2010, was simulcast on sister station KFSD, expanding KSPA's signal into San Diego County. The station aired music programs on the weekends, including Big Band Jump with Don Kennedy, Jazz at The SPA with Jeff Gehringer, Sounds of Sinatra with Sid Mark, and Radio Deluxe with John Pizzarelli. Prior to 2002, KSPA was classic country station KIKA. Before that, it was KMSL, which was the only all-sports station ever to broadcast in the Inland Empire market. The morning show was co-hosted by minor league baseballpublic address announcer David Achord and former National Football Leaguerunning backGreg Bell. The station was owned by the Rancho Cucamonga Quakes baseball team and its call sign was derived from "muscle," a term associated with the stereotypical strength of athletes. KMSL aired Quakes games as part of its programming, as it does now. Before that, it was the leading Spanish-language radio station in the area, KNSE. In November 2010, program director Jeff Gehringer announced that the talk format failed to find an audience and would be dropped. On November 26, 2010, the day after Thanksgiving, KSPA began playing Christmas music, which was also airing on KFSD thus reviving the simulcast. On December 26, both stations returned to their previous adult standards format. That format lasted until March 1, 2012, when it flipped to a business talk format that it inherited from sister station KCEO. KSPA is rumored to be planning a switch to Cumulus Media's syndicated Nash FM country music format in early 2015. In February 2015 KSPA changed their format to country, branded as "KIK Country 1510". On May 18, 2015 KSPA changed its format to Spanish Catholic religious, branded as "Guadalupe Radio". KSPA returned to adult standards on January 1, 2017. In mid-2017, San Jose-based Intelli LLC began operating KSPA under a time brokerage agreement and airing the "Viên Thao Radio" Vietnamese programming which also airs on Intelli's 1290 KAZA in Gilroy, California. In March 2018, Intelli purchased KSPA from Ontario Broadcasting for $1.35 million; the purchase was consummated on August 21, 2018. Intelli also owns KPAM in Troutdale, Oregon and KKOV in Vancouver, Washington. \ KSPA went silent on May 6, 2020. The request for Special Temporary Authority to remain silent, filed two days later, gave the reason as "loss of transmitter site... tower dismantled."
