WTAX's first license was granted on October 11, 1923, to the Williams Hardware Company in Streator, Illinois. The call letters were randomly assigned by the government from a sequential list of available call signs. It was initially on 1300 kHz, with a power of 20 watts.[7] In mid-1927 the station was reassigned to 930 kHz.
Following the establishment of the Federal Radio Commission (FRC), stations were initially issued a series of temporary authorizations starting on May 3, 1927.[8] In addition, they were informed that if they wanted to continue operating, they needed to file a formal license application by January 15, 1928, as the first step in determining whether they met the new "public interest, convenience, or necessity" standard.[9] On May 25, 1928, the FRC issued General Order 32, which notified 164 stations, including WTAX, that "From an examination of your application for future license it does not find that public interest, convenience, or necessity would be served by granting it."[10] However, the station successfully convinced the commission that it should remain licensed.
In 1948, WTAX added an FM station, broadcasting at 103.7 MHz, WTAX-FM. That station is now WDBR. Recently, co-owned 93.9 FM has taken the WTAX-FM call letters to simulcast the news/talk programming on 1240 AM.
Programming was previously also broadcast on 107.5 FM, over translator station W298AP, which once served as a second signal for sister adult hits station WABZ. The W298AP simulcast lasted until January 31, 2017, when W298AP switched to oldies, now simulcasting WDBR's HD3 subchannel.
