WAWA was a radio station licensed to West Allis, Wisconsin, serving the Milwaukee area, located at 1590 AM. Its studio and transmitter were located in Elm Grove. For the station's entire existence, WAWA was the sister station to WAWA-FM (later WLUM-FM). The station signed on the air in 1961, and signed off in 1988, when the owner returned the license to the FCC. Since the FCC no longer re-licenses daytime-only stations, the 1590 AM frequency allocation in the Milwaukee market is considered to be permanently deleted.
