The station primarily targets the Portland, Maine area, but due to the high elevation of Mount Washington, can be heard across a much wider area of Maine and New Hampshire, northern and central Vermont, and parts of southern Quebec, northeastern Massachusetts and the Adirondacks of upstate New York.

[2] Along with WMTW-TV (channel 8), which had signed on in 1954, WMTW-FM was owned by Mount Washington Television, an ownership group that included former Maine governor Horace Hildreth.

[3] For most of its early years, WMTW-FM broadcast a beautiful music format, featuring quarter-hour sweeps of mostly soft instrumentals, with limited talking and commercials.

With the ownership change, the radio station switched its call letters to WWMT in 1972,[6][7] then to WMTQ in 1973,[8] and then finally to the current WHOM in 1976.

[9] The station offered an easy listening format consisting of instrumental versions of pop songs from artists like Henry Mancini, Ray Conniff, Percy Faith, Chet Atkins, and Herb Alpert, as well as several soft vocals per hour like The Carpenters, Dionne Warwick, Johnny Mathis, and Perry Como.
