For more details on the history of 92.7 FM from 1959 to 2004, see WLIR.
92.7 FM went on the air in 1959 with the call letters WLIR and played Broadway tunes and classical music. In the early 1970s, the format shifted to progressive rock, then to modern rock in the 1980s. In 1987, the call sign changed to WDRE-FM, and in 1996 they went back to WLIR-FM. Univision bought the station in 2004 and became a multi-cast for "Latino Mix" WCAA 105.9 FM based in Newark, New Jersey and New York City (WCAA would later start broadcasting at 96.3 FM as the result of a frequency swap with classical music station WQXR.)
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.
