Because 1030 AM is a clear channel frequency reserved for Class A station WBZ in Boston, WNVR must avoid interference.

[5][7][6] The station's call sign stood for "News Voice Radio", its slogan at the time.

[5][7] WNVR was originally owned by Midwest Radio Associates, and ran 500 watts during daytime hours only, with its transmitter located in Mundelein, Illinois.

[5][9][10][11][12][13] In 1993, WNVR was sold to Polnet Communications for $495,000, and the station adopted a Polish language format.

[19][20][21] In 2003, the station's nighttime power was increased to 120 watts, using a directional array at its present location.
