WCMT-AM 1410 was the first radio station to begin broadcasting in Weakley County on June 1957. WCMT's call letters stand for "Weakley County, Martin, Tennessee" and was solely owned by Jones T. Sudbury of Blytheville, Arkansas. The property was purchased from Cliff and Virginia Weldon on highway 45 North which would later become known as North Lindell Street in Martin.
Following deregulation of the FCC in the late 1980s, WCMT- AM became a 24-hour-a-day station but with reduced night time power so as to not cause interference with other stations. This allowed listeners never to have to turn the dial to other stations after sunset. WCMT improved the station's coverage by constructing a new broadcast tower in 1989 which allowed for a stronger signal for listeners.
Thunderbolt Radio receives recognition for St Johns Radiothon. In July 1992 Brundige sold his interest and Tinkle was named President of Thunderbolt Broadcasting and joined a group of local investors to continue to enhance local radio.

The first was for WCMT AM 1410 which now broadcasts on 100.5 FM.
