The station signed on the air on December 22, 1969; 55 years ago (December 22, 1969).[5] The call sign was originally WHMS-FM, broadcasting at 92.1 MHz. It was only powered at 3,000 watts. WHMS-FM was owned by the Flamingo Broadcasting Company on East 2nd Street and played middle of the road (MOR) and easy listening music. In 1972, it changed its call letters to WQXK and aired a country music format.
That ended in 1974. The station decided to serve Miami's growing Hispanic community. The language switched to Spanish and the station began playing oldies that were well-known in Cuba, Puerto Rico and the Dominican Republic from past decades. The station changed its call sign to WCMQ. CMQ640 AM was one of the most popular radio stations in Havana in the 1950s and 60s. Over time, the oldies were reduced as WCMQ began concentrating on Spanish classic hits from more recent decades.
On April 1, 2012, WCMQ-FM changed its format from Spanish classic hits to salsa music, branded as "Zeta 92".[6]
On October 31, 2019, the radio began playing an occasional English-language hit amid the Spanish-language music, with the focus being on songs from the 1970s through 1990s.
