KKBJ-FM (103.7 FM), known as "Mix 103.7", is a radio station based in Bemidji, Minnesota, that airs a Top 40 (CHR) format. It is owned by RP Broadcasting. The station's programming during the daytime hours is local, although night and weekends are satellite fed from Today's Best Hits network.
The station previously had a Top 40 (CHR) format as B-103, "Today's Best Music" and flipped to adult contemporary as Mix 103.7 in 1994, after being sold to RP Broadcasting. The station switched to hot adult contemporary format a few years later. In recent years, the station began evolving to a hybrid of Hot AC and Top 40 (CHR), also known as an Adult Top 40 format.
