KXLS

The 1982 Broadcasting Yearbook lists KXLS as having an MOR format and was licensed to Alva, Oklahoma.  The sticker's border, palm trees and drop shadow on the call letters actually have a mirrored chrome look which can't be duplicated by my scanner.  Inside the black circle at the top of the triangle are the letters ZBC which stood for the now-defunct Zumma Broadcasting Co. (you can almost see it if you click on the sticker.)
