History

WNZK began broadcasting on October 12, 1985. The western Detroit suburb of Westland was its original city of license. It switched to Dearborn Heights by 1990. The station was always owned by Birach Broadcasting. The original studios were at 21700 Northwestern Highway in Southfield, Michigan.
According to the FCC online , WNZK is the only AM radio station in North America using two frequencies, one by day, one at night.
At one time, several radio stations in Detroit were multi-lingual. 97.9 FM aired a similar ethnic format for many years with a similar call sign, WMZK. It used the same "Station of the Nations" slogan until 1980. That station is now urban contemporary WJLB. Several Detroit-area AM stations were also aimed at different ethnic groups. But they have also changed to more mainstream formats.
