The station first signed on the air on December 1, 1951; 73 years ago (1951-12-01). Its original call sign was WGNU and its city of license was Granite City, Illinois.[3] Founded by Chuck Norman and owned by him for the rest of his life, it was held in trust after his 2004 death. Under Norman's ownership, the station featured a wide-ranging local talk radio format. Norman also signed on FMsister station WGNU-FM (now 106.5 WARH) on November 24, 1965.
WGNU was sold to Radio Property Ventures, owners of KXEN, on September 26, 2007. WGNU switched to an urban gospel format.[6][4]
Former KFNS host Tim McKernan and his company, InsideSTL Enterprises, bought the weekday air time on WGNU, and the station switched its weekday programming to sports radio talk on August 1, 2013. The weekday schedule consisted of 11 hours of local shows, as well as programming from CBS Sports Radio. The Urban Talk format continued to air on weekends.[7] This lease agreement ended in September 2016, when insideSTL Enterprises took over the operations of KFNS and moved its programming onto that station.
Controversy
The station briefly made national headlines. Former St. Louis Cardinals player Jack Clark, who cohosted "The King and the Ripper" with longtime St. Louis radio personality Kevin "the King" Slaten, claimed Los Angeles Angels slugger Albert Pujols had used performance-enhancing drugs (PEDs) while Pujols was with the Cardinals. Clark had been the Cardinals' hitting coach during the early part of Pujols' 12-year tenure in St. Louis. Clark had said that he talked to Pujols' former personal trainer and said that "I know for a fact he was" using PEDs.[8]
Pujols responded by threatening Clark and WGNU with a defamation lawsuit, and vehemently denied that he had ever used PEDs. The trainer added that he hadn't even talked to Clark in over ten years. InsideSTL cut ties with Clark and Slaten after only seven shows.[8][9][10] It also issued an apology to Pujols.[11]
Sports betting
In 2018, the station's community of license was changed from Granite City to St. Louis, Missouri.[12]
On March 27, 2023, the station changed its call sign to KWUL. Effective May 8, 2023, Radio Property Ventures sold KWUL, KXEN, and translator K264CY to Louis Eckelkamp's East Central Broadcasting for $210,000.
