History.
The station first signed on the air on September 15, 1963, as KLOC. It was founded by country music artist Chester Smith, who served as general manager. The station was a daytimer, required to go off the air from sunset to sunrise. Reflecting its owner, KLOC played only Country and Western music.
The station was acquired by Threshold Communications in 2001 for $400,000. The call sign was changed to KVIN. It formerly featured programming provided from Jones Radio Network and Dial Global. It was a network affiliate of Westwood One's "America's Best Music" until December 2013.
