The city of license was changed from Slidell to Kenner, where Louis Armstrong New Orleans International Airport is located. It switched to a Hot Adult Contemporary format as WKZN "105.3 The Zone." On August 29, 2005, the station's transmitter was severely damaged during Hurricane Katrina, knocking it off the air. It returned to broadcasting with low power as a temporary simulcast of co-owned WWL 870. Other FM stations in New Orleans suspended their music formats during the storm's aftermath to rebroadcast news from local TV stations. In early October 2005, Entercom decided to switch two of its New Orleans FM station dial positions. 95.7 WTKL and WKBU Bayou 105.3 switched frequencies. The 105.3 frequency became WTKL with a classic hits format and the "Kool" name, formerly "Kool 95.7." Only three weeks later, it was decided by Entercom to scrap the classic hits format and return 105.3 to the WWL simulcast. Entercom cited positive listener response to WWL being heard on FM and complaints about its removal from the FM dial. Some listeners said they wanted WWL programming to remain on FM due to issues receiving the AM station in the New Orleans Central Business District. The "Kool 105.3" format continued as an Internet-only webcast for a short time it was discontinued on FM. With 105.3 simulcasting WWL, Entercom asked the Federal Communications Commission (FCC) to switch the call letters to WWL-FM. Sister station 101.9 WLMG was the original home of the WWL-FM call sign, from 1970 to 1980, airing beautiful music at first, and then Top 40 hits.
