Before WQBU aired Mexican music, it was WDRE-FM, and later WLIR-FM. Univision bought the station in 2004 and became a multi-cast for "Latino Mix" WHBI 105.9 FM based in Newark, New Jersey.
On Memorial Day 2005, both stations became "La Kalle," a reggaeton-formatted station. The station at 105.9 became WCAA and 92.7 became WZAA.
In late January 2007, Univision ended the simulcast and changed the call sign to WQBU.
In March 2007, the station announced that they would become the Spanish-language home of the New York Yankees. Beto Villa is the play-by-play announcer. [1]
