The station began broadcasting October 7, 1950. The station's call sign was originally WEBS, but before going on the air the call sign was changed to WOPA to reflect the location of its studios. The studios and antenna were in the former Oak Park Arms Hotel, now a retirement community.

Pervis Spann began his radio career on WOPA in 1959.

In 1984, the station's call sign was changed to WBMX.

In January 1987, the station was sold to the Polish National Alliance for $2 million, and its call sign was changed to WPNA on May 1, 1987. WPNA was the home of the long-running Chet Gulinski Show, which featured polka music and was quite popular in Chicago's Eastern European communities.

On May 25, 2022, the Polish National Alliance announced the sale of WPNA to Daniela Wojcik's CSWWII, LLC for $725,000. The sale was consummated on August 1, 2022. Alliance Communications, which still owns 103.1 WPNA-FM, retained the rights to the WPNA call sign and intellectual property. The station changed its call sign to WEUR on August 31, 2022.
