The 93.7 frequency first signed on in the late 1960s as WLVH, the first Spanish-language radio station in the state of Connecticut. Though the station had a loyal audience, the concept of a Spanish-language FM station in an area with a (then) relatively small Hispanic population was seen as being ahead of its time. With FM prices rising, WLVH later bought 1550 kHz (today's WSDK) and in 1991, sold 93.7 to American Radio Systems with WLVH moving to AM. With ARS's takeover came the change to a stint with the local NOAA weather signal for a week before the launch of the new format: Hot Adult Contemporary, as WZMX, chosen for the station's mix format by PD Herb Crowe (Max on KIIM FM Tucson AZ) and Ron O - Midday DJ, the first on air announcer on Mix. The "Mix" format promised listeners a mix of different varieties of music with little talk or DJ chatter, a directive reflected in the slogan "Four Songs in a row - No talk".

Other DJs included Monk & Kelly-Mornings, Jonathan Monk of WTIC FM Hartford, WERI FM 'RI-104' Westerly RI alumni, Diana Kelly, Jon's wife also WTIC Hartford alumni, Ron O-Middays and Production Coordinator, later, Donna Rose-Middays, Neil Jackson-Afternoons, Ted Dalaku-Nights. Danny Wright did live overnights.

In spite of being a "new" station for the majority of the market's listeners, the Mix format began well; though the format started to flounder. The purchase of rival WTIC-FM by ARS in 1994 and its subsequent conversion to a Hot AC format led ARS to flip the younger WZMX to an all-70s format in the middle of that year. To boost the station's listenership, WZMX hired popular morning drive host Sebastian away from WCCC in February 1995, engaged well-known announcer Chuck Riley to be the station's voiceover talent. After a downturn in 1996, the station added 1960s and 1980s music and reimaged itself as Classic Hits 93-7.

The Classic Hits period produced lot of creative programming, such as "Saturday specials" which followed a theme (i.e., all disco music, music of the 80's, management staff hosting shows), ran countdowns that at times featured hundreds of songs, and was the Connecticut home of New England Patriots football games and an overflow home of Hartford Whalers hockey games.

By 1998, Classic Hits ran its course and rumors of a format change circulated. After CBS Radio took over the ARS stations that Spring, WZMX's format evolved into a broad-based, classic-leaning, rock format as The Point. This format never had any sort of success, and on May 6, 1999, at 10 AM, WZMX flipped to a "Jammin' Oldies"-style format as Dancin' Oldies Z93.7. As with other stations in that format (and as with past formats of 93.7's existence), the format had early success, but soon dropped in the ratings, and was still the lowest rated station in the Hartford market.

On March 16, 2001, WZMX flipped to an urban-leaning Rhythmic format as Hot 93.7, based on that of sister station WPGC-FM in Washington, DC. The last song on Z93.7 was Last Dance by Donna Summer, while the first song on Hot 93.7 was "Stutter" by Joe. The first station playing such a format on FM in the Hartford, New Haven and Springfield, Massachusetts markets, WZMX would soon become a regular Top 5 station and often has been the #1 station in the market. Coincidentally, that same format had been proposed as a replacement twice before but was rejected for fear that it would not work in Hartford. The success of Hot 93.7 led to the launch of rival WPHH (Power 104.1) in 2003, which had a limited effect on WZMX's success. WPHH was also the sister station of Top 40 Mainstream WKSS, whose once-dominant hold on Hartford's Top 40 scene would take a major beating in the wake of WZMX's arrival, which in turn may have served as one of the reason behind WPHH's debut. In addition, WZMX also has competition with WKSS and WPHH's sister station in New Haven, Top 40 WKCI, who has also seen its listener base erode slightly after Hot 93.7's debut.
