WKQZ can be reached in most of the Mid-Michigan thumb as the signal increases as listeners travel north toward Midland, and decreases as listeners travel south of Flint and Lapeer. As listeners travel southward, WDRQ 93.1 Detroit's signal tends to "bleed" into WKQZ's signal.
What is now Z93 was originally WRCI "Easy 93-5", an adult contemporary music station at 93.5 FM in Midland. WRCI was locally programmed at first, but in 1982 affiliated with the "Star Station" adult contemporary format delivered via satellite by Satellite Music Network. The station then tried a country format, known as "Kickin' Country 93.5 WRCI", for a very short period of time. After going off the air briefly, the station changed its calls to WKQZ and adopted its current rock format in 1986, and the station soon afterward shifted from 93.5 to 93.3, enabling a boost in power from 3,000 to 39,000 watts.
