WNDZ (750 kHz) is a commercial AM radio station broadcasting an ethnic brokered programming format.
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.
[3] WNDZ is a brokered programming station, where hosts pay for their time on the air and may advertise their products and services or seek donations.
[10][11] In late May 1998, the station switched from brokered programming to the motivational "Personal Achievement Radio" network, which moved from WYPA 820.
