AM 1530 signed on the air October 10, 1974. The station’s call letters were originally WKDC representing the signal coverage in Will, Kane, DuPage and Cook counties. The studios were built for stereo (Cetec Sparta stereo audio equipment) although it was not until 1976 when the FCC authorized the station to test AM stereo. Daytime and night-time findings on AM stereo were presented at the 1977 NAB Convention in Washington, DC.
In 1994, AM 1530 changed its call sign to WJJG. The call letters stood for owner Joseph J. Gentile. Joe’s nickname is “The Baron of Barrington,” where he owned a Chrysler-Plymouth dealership for many years.
In 1998, the station began broadcasting over the radio as "105.9 Cyber Radio", the first online radio station in Chicago.
On September 19, 2012, AM 1530 changed its call letters to WCKG.
