KBRC signed on the air on December 11, 1946; 78 years ago (1946-12-11). It was owned by Leo H. Beckley and was the first radio station to broadcast in the Skagit Valley region.[3] Through the 1950s, 60s and 70s, the station aired a full service, middle of the road (MOR) format of popular adult music, news and sports. By the 1980s, it switched to adult contemporary music.
In the 1990s, the station flipped to a classic hits-oldies format of music from the 1960s, 70s and 80s. KBRC would also broadcast local Skagit County news as well as hourly updates from ABC News Radio.
On November 19, 2018, KBRC changed its format from classic hits to classic rock.[4] It began promoting its FM translator as its primary dial position.
