WHNM traces its origins to New Hampshire's first broadcast radio station, WKAV, an experimental station run by a local radio club, which went on the air in 1922 but went dark about a decade later after a myriad of financial problems. In 1934, the station was reborn under a new license as WLNH at 1310 kHz on the AM dial, moving to 1340 in 1941 and to the current 1350 frequency in 1954.
The station would change to WKZU in 1983[2] and WMRS in 1985,[3] before returning to WLNH in 1987 and becoming WEZS in June 1994.[4] As WEZS, the station initially featured a beautiful music/easy listening format, which was eventually modified to smooth jazz. WEZS was a rare AM station to play smooth jazz, along with WCIN in Cincinnati, Ohio.
WEZS began an FM simulcast on translator W277DJ 103.3 in June 2018.
According to North East Radio Watch, in January 2023, the station changed its call letters to WHNM on January 14 and nickname to "The Moose 103.3", with a classic hits format.[5][6] The changes were associated with the sale of the station and its translator by Gary W. Hammond to Patrick Costa's Costa-Eagle Radio Ventures Limited Partnership. The sale was consummated on January 25, 2023, at a price of $225,000.
