The name "Duke" automatically conjures up visions of John Wayne and nomadic, gunslinging cowboys. So when a radio station brands itself "Duke" it couldn't be anything but Classic Country.
WGEE / WDKF - New London/Sturgeon Bay/(W)GrEEn Bay, Wisconsin
WDKW - Maryville/Knoxville, Tennessee
WWDK - Jackson/Lansing, Michigan
All three of these stations are operated by Midwest Communications whose owner is named Duke Wright. Coincidence?
