The station went in the air in July 1969, and by 1975 had 3000 watts on 103.1 MHz using the callsign WPOK-FM, simulcasting its sister station 1080 WPOK (AM), also in Pontiac.[2] WPOK-FM changed its callsign to WJEZ in November 1984;[3] the AM station eventually went off the air by 1998.[4] WJEZ was a modern country station by 1989,[1] and received authorization to move from 103.1 MHz to 93.7 MHz in the early 1990s.[5]

In 2003, the WJEZ callsign was moved to sister station 98.9 at Dwight, Illinois; that station still remains WJEZ as of 2010. 93.7 became WTRX-FM, a classic rock station with the nickname "Thunder 93.7 WTRX". It later became "WTRX, The Oldies Channel", from the name of the Westwood One's music network format it used; the music network was purchased by Dial Global and WTRX-FM began using Dial Global's Kool Gold format, except during mornings.

In 2010, the station changed its callsign to WJBC-FM and began simulcasting sister station 1230 WJBC (AM) from Bloomington.

On August 15, 2014, at 3pm, WJBC-FM split from the simulcast and became one of the first stations to flip to the new "Nash Icons" country network as 93.7 Nash Icon.
