KUJ-FM signed on the air in 1996; 28 years ago (1996). It began with a rhythmic adult contemporary format. It originally was the sister station to KUJ 1420 AM. The two stations still share call letters but are no longer co-owned.

In 1999, under the direction of Program Director Dave Hilton, KUJ-FM shifted from Rhythmic to Mainstream CHR, thus garnering the station its highest 18-34 ratings ever. Unable to sell the station's high ratings, New Northwest Broadcasters, under the direction of Scotty Brink and Jeff Jacobs, shifted KUJ-FM back in a rhythmic direction in the Spring of 2002.

KUJ-FM returned to Mainstream CHR in March 2007. It competes with 105.3 KONA-FM in Kennewick, Washington, for Top 40 listeners.
