Notes: Originally WNAD and licensed to Norman, the station programmed many formats over the years. In 1981, the call letters changed to WWLS. The “LS” stood for Larry Steckline, a controversial owner of radio stations in Oklahoma and Kansas. After the change to WWLS, the format went from country to oldies. Over time, the amount of sports broadcast increased. Al Eschbach, an iconic sports talk host, moved over from KTOK to WWLS in the 1980s.
This station morphed from oldies to sports at some point around 1985 or 1986, settling as SportsRadio 640.
Fox Broadcasting (who later owned KNOR/KREF-AM 1400) bought the station in 1989 and owned the station until 1998 when Citadel Broadcasting (then-Caribou Broadcasting) bought the station and combined it with Sports Talk 1340 (a time-brokered operation on Clear Channel’s KEBC-AM 1340) on this frequency and then KNTL-FM 104.9.
AM 640 was a constant as the FM simulcast frequency changed four times in 14 years.
In 2012, the simulcast was split and AM 640 became a full-time ESPN affiliate and took the KWPN call letters. KWPN still simulcasts WWLS-FM during Oklahoma City Thunder basketball games and University of Oklahoma and Oklahoma State football pre- and post-game programming.
