In 1969, a sister station, WGLB-FM, was launched on 100.1 MHz (now WSJP-FM). At first, they mostly simulcast their programming. In 1995, WGLB was purchased by Joel Kinlow, a Milwaukee area minister, out of bankruptcy for $311,900.[4] Kinlow split the simulcast in 1996, replacing their soft adult contemporary and jazz programming with black gospel on AM 1560 and 1970s oldies on WGLB-FM.[5] In 2003, the FM station was sold to Starboard Broadcasting, which flipped it to Catholic religious programming. Kinlow also once owned television station WJJA (channel 49) in Racine, which aired programming from the Home Shopping Network (HSN).
In August 2001, WGLB's city of license was changed to the Milwaukee suburb of Elm Grove, and the current transmitter site went into operation. The station also obtained authorization to begin nighttime broadcasting.
