KSGM AM transmitted its first broadcast on July 5, 1947 from Ste. Genevieve, Missouri. KSGM was located at 1450 on the AM dial with a power output of 250 watts. KSGM's pioneer broadcasting schedule included local news of interest to the Chester community, religious broadcasts from St. John Evangelical Lutheran Church, sports from Chester High School and special programming from Menard State Prison.
KSGM's friendship with the Chester Community continued to grow and as early as 1954, KSGM established studios in the First Bank Building in downtown Chester.
In 1961, KSGM was relicensed to Chester. KSGM improved their dial position from 1450 to the familiar 980, and increased our power to 1,000 watts.
A considerable list of wonderful personalities performed on KSGM over the last 50 years, the list is too numerous to mention. Chester's KSGM AM today teams with KBDZ FM in Perryville to serve a wider area in Southern Illinois and Southeast Missouri with entertainment and information.
KSGM provides live sports coverage of Chester High School Yellow Jacket sports in addition to sports coverage of St. Vincent Catholic, Perryville, Ste. Genevieve and Valle Catholic High Schools in Missouri.
