WMAS-FM (94.7 MHz), branded 94.7 WMAS, is a commercial radio station licensed to Enfield, Connecticut, and serving the Springfield metropolitan area and Pioneer Valley of Western Massachusetts.

Advertising revenue came from the hippie boutiques, head shops, concert venues, and music stores that catered to the counter-cultural youth of the day.

[citation needed] This freeform radio format ended in September 1969 after complaints were made about expletives in a Wild Man Fischer song.

Ham Agnew was also the licensed Chief Engineer of the station in addition to being the architect of the "Progressive-Free Form" format, and resigned shortly after a meeting with Roy Cohn and Tony Gazzana.

[citation needed] In 1979, WMAS-FM began airing a soft adult contemporary format, a forerunner of what the station is today.

In June 2004, WMAS-AM-FM were sold to Citadel Broadcasting for $22 million;[4] In January 2011, WMAS-FM agreed to change its city of license from Springfield to Enfield, Connecticut, to facilitate the relocation of WPKX (97.9) from Enfield to Windsor Locks; the deal, which allowed Citadel to use a generator owned by WPKX owner Clear Channel Communications in Albuquerque, New Mexico, did not require any changes to WMAS-FM's physical and studio facilities.

The Kellogg Krew Morning Show won the Massachusetts Broadcasters Association "Air Talent of the Year" award in 2013.
