The station broadcast on AM frequency 1530 kHz and was last under the ownership of Paulino Bernal Evangelism.
The station was founded in 1963 by Phil Crenshaw and Gaylon O. Gilbert.
Because it shared the same frequency as clear-channel station WCKY in Cincinnati, Ohio, KCLR operated only during the daytime hours.
The station sought the letters KCLR, for "K-Clear", because of its placement on a clear channel.
Bernal surrendered the license for KCLR and five other stations to the Federal Communications Commission on November 7, 2013.
