KNOR

1400 AM KNOR went on the air in (K) NORman, Oklahoma in 1949.  A 1994 article from The Oklahoman newspaper says that KNOR's owner was willing to donate the station to the University of Oklahoma.  I can find no evidence that this ever happened.  This OUDAILY article from 1996 says that the station started a show called "The Fringe" playing Alternative Rock on Friday and Saturday nights.  While the show was run by OU students, they were not sponsored by the university.
1400 AM currently airs a Sports format with the call letters KREF.
Obviously, the bottom sticker is suffering from some bad ink issues.
