WZTU 94.9: A History of Miami Radio Evolution
The airwaves of Miami have always been a reflection of the city's shifting culture, tastes, and demographics. One frequency in particular has undergone a remarkable transformation over the decades, evolving from a simulcast of early AM radio to a modern Hispanic powerhouse. The journey of the station now known as WZTU is a chronicle of the broader American radio industry, marked by changes in ownership, format flips, and the rise of stereo broadcasting.
The Early Years: WQAM-FM and WAEZ
The story begins in 1947 with the launch of WQAM-FM, owned by the Miami Herald. In its infancy, the station served as a full-time simulcast—broadcasting the same content as its AM counterpart, WQAM. However, this first iteration was short-lived. In 1957, Storz Broadcasting purchased WQAM and, seeing little value in the FM band at the time, took the signal off the air and returned the license to the Federal Communications Commission (FCC).
A new era began in 1962 with the arrival of WAEZ. Operating with 81,000 watts, WAEZ made history as the first station in Miami to broadcast continuously in stereo. Owned by Arthur E. Zucker (whose initials formed the "AEZ" call sign), the station broadcasted easy listening music from the Deauville Hotel in Miami Beach.

By 1969, the station became WOCN-FM to align with its sister station, WOCN. While maintaining its easy listening roots, it experimented with Spanish-language romance music and was briefly branded as "Stereo 94" in the mid-1970s.
The mid-70s brought a dramatic shift in identity. In 1975, under Guy Gannett Broadcasting, the station became WINZ-FM. It adopted a progressive rock format known as "Zeta-4." This rock identity evolved in 1981 when the station flipped to a CHR (Contemporary Hit Radio) and Pop format branded as "I-95." As an affiliate for Dan Ingram's Top 40 Satellite Survey, "I-95" engaged in a fierce ratings battle with WHYI, eventually reaching the #1 spot in the Miami ARB (Arbitron) ratings. By early 1986, the station attempted a hybrid of classic rock and adult hits as "Rockin' With Class....95-INZ."
In early 1987, the station fully committed to the rock genre, rebranding as "Zeta" with the call letters WZTA. This marked the beginning of a nearly two-decade tenure as a rock destination. During the 1990s, the station transitioned through ownership from Paxson Communications to Clear Channel Communications (now known as iHeartMedia). Under this leadership, WZTA evolved into an active rock format—a style focusing on harder, modern rock tracks. Despite a brief foray into alternative rock in the early 2000s, the station returned to active rock in 2004. However, declining ratings led to the end of the Zeta era on February 10, 2005.

Following the demise of Zeta, Clear Channel launched WMGE, known as Mega 94.9. This move was part of a larger strategic effort led by Alfredo Alonso to expand Hispanic radio offerings in the market. Mega 94.9 operated as a hybrid of English and Spanish language urban programming. Interestingly, the exit of WZTA left a void for rock fans, prompting Cox Radio to flip its dance station, Party 93.1, to the active rock format as 93Rock (WHDR) on February 14, 2005.
Mega 94.9 struggled to maintain its audience and, after two years, shifted to a Hispanic Top 40 format in 2007. The final major evolution occurred on September 9, 2016, when WMGE rebranded as "Tú 94.9." Shortly after, on September 16, 2016, the station adopted its current call sign, WZTU.
