Mark Wheat grew up near Cambridge, England, where he regularly listened to the late great BBC DJ John Peel. Like Peel, Wheat came to the USA to start his radio career. Emigrating in 1983, Wheat lived in St. Louis, in Kure Beach, N.C., and in Hoboken, N.J. It was while living in Hoboken that Wheat learned how to push the buttons at the legendary free-form station WFMU.
After moving to the Twin Cities in 1992, Wheat volunteered at community radio station KFAI and created Local Sound Department, playing only Minnesota music. Wheat spent 18 months at commercial station Zone 105, hosting Across The Pond, a weekly show playing music from all over the world. In 1998, he became Director of Student Programming at the University of Minnesota's Radio K, and created a weekly magazine show, The Music Lovers Club.
Wheat hosted weekdays 6 to 10 p.m., including The Chart Show on Wednesdays at 8 p.m. from 2005 until 2020.
