A radio station in St. Joseph Missouri with the call letters, KRES originally debuted in 1947 at 1550 AM. The KKJO call letters were adopted in 1962, and KRES today is used by a country station in Moberly, Missouri. The middle of the road format was dropped in 1966 for Top 40. Calling themselves Tiger Radio, KKJO was St. Joseph's version of Top-40 radio akin to the pioneering sound at nearby WHB in Kansas City. As the 70s passed, KKJO became more oriented to oldies, and into the 80s it had acquired more sports and talk oriented programming.

The FM counterpart to KKJO, originally at 105.1 MHz, debuted in 1960. KUSN-FM simulcasted with Top 40 KUSN-AM at 1270 kHz. in the wake of KKJO's success, KUSN AM-FM switched to a modern country format in 1968. KUSN-FM's call letters were changed to KSFT (K-Soft) in 1974 to reflect a new automated ["Beautiful Music"] Beautiful music format which was adopted at the time. In 1977, KSFT (T-105) adopted an automated Top Forty format, moved to Album Rock in 1978, and when it was acquired from KUSN in 1979, it was switched to a successful country format.

KKJO swapped frequencies with KSFT on March 1, 1989, moving the country format to the AM, and KKJO (K-JO 105) shifted to Contemporary Hit Radio (Top 40). In 1992, in the wake of the growing presence of rhythmic tracks on Top-40, KKJO became Hot Adult Contemporary while KSFT started broadcasting satellite formats, first adult standards and later oldies. In April 2000, KKJO moved to 105.5 as Susquehanna prepared to introduce a short-lived '80s music format, KFME. Today, KKJO retains its hot adult contemporary format while including tracks from the 70s and 80s, both in rotation and in hour-long segments nightly.
