KJYO, known as "KJ103", is a Top 40 (CHR) radio station serving the Oklahoma City area and is owned by iHeartMedia. Its transmitter is located in Northeast Oklahoma City, and studios are located at the 50 Penn Place building on the Northwest side.


The station began broadcasting April 8, 1961 as KJEM-FM, sister to KJEM (800 AM), and adopted an adult standards format. Studios were located where the Oklahoma City Federal Building (Murrah Building) once stood. It changed calls in 1972 to KAFG and ran an automated oldies format. KAFG's transmitter site was at 23rd and N. Classen on top of the Citizen's National Bank tower.

In May 1977 it re-launched as a rock station known as "The Zoo" and adopted the call letters KZUE. During this time it was owned by INSILCO Broadcasting which later changed its name to Clear Channel Radio, and eventually iHeartMedia. After losing its audience to the then new KOFM (now Magic 104.1), it became an AC station known as "Z-103" in 1979. The station adopted the handle "K-Joy" (The Joy of Oklahoma) and an easy listening format in 1981 and changed its call letters to KJYO. It has been a Top 40 (CHR) since 1983 but leaned towards the Rhythmic Top 40 format in 1989-1991 when it was known as "Kontinuous Jams." In late 2007 KJYO-HD2 was launched with a New Music format. In late 2015 KJYO-HD2 changed New Music format to iHeartRadio Music Festival.
