WNWI (1080 AM) is a time brokered radio station broadcasting an ethnic radio format. Licensed to Oak Lawn, Illinois, USA, it serves the Chicago area. The station is currently owned by the Birach Broadcasting Corporation. WNWI operates on a clear-channel frequency, with WTIC (AM) in Hartford, Connecticut and KRLD (AM) in Dallas, Texas the dominant Class A stations.
WNWI's calls stand for "Northwestern Indiana", a reference to the station's former city of license of Valparaiso, Indiana. The station broadcast a full-service adult contemporary music format from Valparaiso from its sign-on in 1965 until the spring of 1998, when it officially moved into the Chicago market by changing its city of license to Oak Lawn and relocating its transmitter to Riverdale.
The bulk of WNWI's programming is Polish language music, news, and talk programming. Other weekday programming includes Serbian Radio Chicago, a one-hour radio show hosted by Milorad Ravasi which incorporates news, music, and interviews from Serbian culture. On weekends, programming blocks variously target the German, Macedonian, Polish, and Serbian communities.
