The station signed on the air in 1951 under the call letters WKIN and was soon owned by Cy Bahakel. The station was originally daytime-only and, over the years, increased its power to 5,000 watts.
In the 1960s and 1970s the station was a popular Top 40 outlet with a personality-DJ format. Some key names over the years included:
Bill Austin
Eddie Skelton
Joe Mills
Phil Roberts
John Selby Engineer
Gary Morse
Dick Winstead ("Richard Bailey Winstead," "Dickie-Doo")
Nighttime service was added in 1981 with a new 4-tower directional array at the intersection of East Stone Drive and New Beason Well Road in Kingsport, and a nighttime power of 500 watts. The 5-kW daytime operation was consolidated to this site as well in about 1990.
In 1982 WKIN changed to a country format under the branding "A Great Brand Of Country." Variations of country and classic country would continue over the next couple of decades.
The WGOC callsign was on 640 AM from April 9, 1993 until February 26, 2007, when the callsign was moved to what had been WKIN,[2][3] a news/talk and sports station.[4]
