WJMJ is a non-commercial radio station licensed to St. Thomas Seminary in Bloomfield, Connecticut, broadcasting on 88.9 FM, with translators on 107.1 in New Haven, Connecticut and on 93.1 in Hamden, Connecticut. WJMJ reaches central Connecticut, south central and western Massachusetts, and also streams online. The main tower is located on top of Johnnycake Mountain in Burlington, Connecticut. JMJ stands for Jesus Mary Joseph. The current programming consists of "music you can't hear anywhere else," including adult contemporary, jazz, soft rock, adult standards, classical music, and Roman Catholic religious programming, along with ABC News. The slogan for the station is “Catholic Radio – Where Faith Meets Life”.
In 1976, WJMJ was founded by the late Archbishop John F. Whealon, as a way to bring the Gospel to a wider audience through a format of inspiring messages and pleasant music. WJMJ claims to be the first archdiocesan-operated radio station in the United States. When WJMJ first went on the air the studios were located in Glastonbury, Connecticut. They moved to Bloomfield in the early 1980s. A fire tower originally stood where the WJMJ radio tower now stands. In 2009, the WJMJ studios were moved to Prospect, CT, which also houses the Office of Radio and Television of the Archdiocese of Hartford.
WJMJ replaced most of their non-Catholic programming in June 2008. “Festival of Faith”, the 14-hour block of radio shows on Sunday which ranged from short inspirational spots to recorded worship services or talk shows produced by an assortment of area Protestant and Eastern Orthodox churches was replaced beginning Sunday, June 1, 2008 by local Catholic programming, as well as material from the EWTN network. WJMJ also carries live Metropolitan Opera broadcasts on Saturday afternoons.
After many years of broadcasting in monaural, stereo broadcasts have begun in January 2009.
