History pre-1988

KJKK started as KBOX-FM ("K-Box"), playing easy listening and occasional jazz music in 1965. Although it was the sister station of KBOX-AM 1480 (now KBXD), a Top 40 and then country music giant during the 1960s and 1970s, the two stations never simulcasted until 1982, when AM 1480 became KMEZ-AM. In 1973, the call letters were changed to KTLC (meaning Tender Loving Care for your ears) while maintaining its easy listening format. 3 years later, the callsign was changed once again to KMEZ and carried the new branding EZ 100, while still maintaining the easy listening format and was a flagship station for SMU College football.
