WNDZ (750 kHz) is a commercial AM radio station broadcasting a Classic Hits format. Licensed to Portage, Indiana, it serves the Chicago metropolitan area. The station is owned by Newsweb Corporation.
WNDZ is a daytimer station. It transmits 15,000 watts. To send its signal toward Chicago from its transmitter site, it uses a directional antenna with a three-tower array. Because 750 AM is a clear channel frequency reserved for Class A station WSB in Atlanta, WNDZ must go off the air at sunset to avoid interference. The towers are on Bay Road at Robbins Road in Portage.
