WCRU

On January 1, 1963, the station first signed on with the call sign WAAK. The original city of license was Concord with 1,000 watts daytime and nighttime.

Fred Whitley, owner of WGTL in neighboring Kannapolis had applied for this frequency as a daytime-only station in Dallas in order to keep new competition out of his market. He won the construction permit for the station in Dallas, took the call letters WAAK off the top of the Federal Communications Commission (FCC) call sign list, refurbished WGTL's studio, buying the audio board from WSJS-TV, and put the old WGTL console in Dallas.

William E. Rumple was the Chief Engineer of the station for the entire time that Fred Whitley owned it. Whitley ran the station on a break-even basis for about 25 years. In the mid-1980s he sold it to the Marlow Brothers from New Jersey.

The new ownership made sweeping changes to the station, switching it from Easy Listening and Middle of the Road music, which aired during the Whitley years, to an Adult Top 40 sound. Another tower was added to allow the station to broadcast at night.

The establishment of several Top 40 stations in the Charlotte market eroded the listenership of WAAK. By 1990, the station was sold again and moved to a Christian radio format. Several ownership changes took place over the next decade.

In December 2002, WAAK was sold to The Zybek Media Group. Zybek flipped it to a talk radio format. The call letters were changed to WZRH with the moniker "The Z-Monster". The new owners immediately filed for a power increase in an attempt to place a stronger signal over the city of Charlotte. The initials ZRH of WZRH stood for Zachary Richard Howerton, son of owners Rick and Beth Howerton.

As Rick's on-going health problems continued to worsen, broadcast duties were given to Brian O'Brian, until the station was sold. Because of the increase in power, there was a great deal interest in the purchase of the station. The station was sold in mid-2004. Jim Huggins assumed general manager duties and hosted the morning drive time show for approximately a year until the format was changed from talk to Christian radio by Truth Broadcasting.

Two years later, the station was sold yet again to Truth Broadcasting of Winston-Salem. On May 21, 2007, the station began airing Christian talk and teaching programs 24/7. In early 2008, the station's call letters were changed to WCRU to match the call letters and programming format of Truth Broadcasting's other AM stations, WTRU in the Piedmont Triad and WDRU in the Research Triangle.

Truth Broadcasting added two FM translators in Davidson and Pineville. These not only provide an option for listeners who prefer FM radio, but fills in the gaps when the main signal must reduce power at sunset; WCRU's nighttime signal is effectively limited to Gaston County.
