Original Report 1/30: Champlin Broadcasting will begin shifting “True Oldies 1640” KZLS Enid/Oklahoma City to Talk on Monday, February 3.
Reid Mullins, who had hosted mornings at Clear Channel Talk 1000 KTOK until last August will join the station Monday for a daily program from 7-10am. McCarvilleReport.com states that “The new show on KZLS will bring back the “information and news” paradigm that former KTOK listeners were accustomed to, Mullins said. Guests will include local, state, and national political figures, commentators, and experts in various fields and sectors from agriculture, energy, healthcare, immigration and more.”
Mullins joining KZLS will kick off another format change at the station, which picked up the Oldies format and KZLS call letters when sister Classic Country “99.7 Hank-FM” KNAH debuted in late September. KZLS will shift to News/Talk in all dayparts by the end of February.

It was areal treat to hear the Oldies on 1640 via skywave at night in the Dallas area. They had a real nice processor setting too and were not handicapped by the reduced analog bandwidth which so many AM stations seem to run as a default these days. Nothing like Oldies in marvelous mono on skywave. I knew it was too good to last 🙁
