KNSJ (89.1 FM) is a listener-supported community radio station licensed to Descanso, California, serving San Diego's Mountain Empire and the wider San Diego area. It airs locally produced public-affairs talk, free-form music and Spanish-language shows, alongside news from the BBC and Pacifica Radio. After a winter storm toppled its broadcast tower in February 2026, the station streams online full-time while raising funds to return to the FM airwaves.
