Licensed to Manchester, Connecticut, United States, the station serves the Hartford-New Britain-Middletown area.

WTHT was Hartford's third radio station, affiliated with the Mutual Broadcasting System from 1936 to 1945 and ABC from 1945 to 1954.

As a result, WTHT radio left the air on February 13, 1954; WONS became WGTH, which added ABC programming to its schedule.

In 1994, the studios were moved to the fourth floor of a building on Cedar Street in Hartford, and the station—then WLAT—operated with a Spanish-language format under new ownership.

In 1999, Alfredo Alonso's Mega Broadcasting purchased the station for $575,000 from Jeffrey Dressler.
