WPJX 1500 is an AM radio station, licensed to Zion, Illinois, that has aired a Spanish format since February 2011. The station is owned by Polnet Communications, who also owns WKTA Evanston, WNVR Vernon Hills, and WEEF Highland Park-Deerfield. The station transmits with a directional 250 watts of power from 3 towers located on the corner of Delany Road and 21st Street near Wadsworth, Illinois. The station's daytime signal serves northern Lake County, Illinois and Kenosha County, Wisconsin. WPJX was licensed to operate during daytime hours only until May 2009 when it began broadcasting 24 hours a day with a power of 250 watts daytime and 2 watts nighttime.
The station has had several formats over the years, which have included Latin Jazz, sports talk (ESPN Radio), Classical, Classic Country, Gospel, and Adult Contemporary. The station was once co-owned with WKZN 96.9 (later WNIZ and now WWDV) and had studios in downtown Zion when they were co-owned.
In 1983, the station's callsign was changed to WNIZ, and the station began airing a Classical music format, simulcasting the programming of its sister stations WNIZ 96.9 and WNIB 97.1. In 1984, Lake County Broadcasting Co. purchased the station from Northern Illinois Broadcasting Co. for $200,000. On December 1, 1984, the station's callsign was changed to WRJR.
On June 24, 1996, the station's callsign was changed to WTAU. As WTAU, the station aired a Regional Mexican format as "La Mexicana", simulcasting with 1300 WTAQ. WTAU and WTAQ were both owned by Lotus Communications Corporation at this time.
In July 1998, the station became an affiliate of Radio Disney along with its sister station WTAQ. On December 3, 1998, the station's callsign was changed to WDDZ. The station continued to simulcast Radio Disney with its sister station WRDZ until it was taken off the air in January 2000.
Between 2000 and 2002 the station spent much of its time off the air while its previous owner ABC Radio was working on selling it off. On May 16, 2001, the station's callsign was changed to WPJX. A short-lived LMA to the owners of WBJX Racine, WI (now WJTI) brought the station back on the air for a short period in the spring and summer of 2001 simulcasting WBJX and airing its own Regional Mexican music from the Shiloh Mall in downtown Zion. The station then signed off the air until spring 2002 with occasional "tests" to keep the license going with easy listening music in the fall of 2001. It returned to the air permanently in spring 2002 first with its previous format, a simulcast of Radio Disney station WRDZ La Grange.
In 2006, Polnet bought the station from Multicultural Broadcasting for $230,000. When Polnet bought the station, the format was changed to a feed of Radio Fórmula. On February 11, 2009, Radio Fórmula was replaced by the Hard rock/Heavy metal format "Rebel Radio". "Rebel Radio" was replaced by a syndicated Spanish format in mid-February 2011.
