It was an affiliate of the NBC Red Network in its early years, eventually shifting to the Mutual Broadcasting System.
The WCHR call letters and religious format originated on WTTM's sister station at 94.5 FM in 1969 and remained there for nearly 30 years.
The switch began with a period of simulcasting that started in November 1997; by the end of February 1998 WCHR was heard on AM only.
The WTTM call sign was subsequently used on a co-owned expanded band AM station licensed to Princeton, which broadcast a sports format with programming from ESPN Radio.
On January 7, 2008, 920 dropped the sports format and returned to WCHR's religious programming as the 1040 facility was converted into WNJE, a simulcast of ESPN Radio's New York City station, WEPN.

The station had been carrying Fox Sports Radio programming in the late night and overnight time periods.
