WHYN-FM (93.1 MHz "Mix 93.1") is a commercial radio station licensed to Springfield, and serving the Pioneer Valley of Western Massachusetts.

It carries several nationally syndicated shows from co-owned Premiere Networks, including On with Mario Lopez weekday evenings and American Top 40 with Ryan Seacrest on Sundays.

The studios and offices are in downtown Springfield's "Marketplace" along with sister stations 560 WHYN (talk radio), and 100.9 WRNX (country music).

The transmitter is atop Mount Tom in Holyoke, Massachusetts, more than 1,001 feet (305 meters) in height above average terrain (HAAT).

[6] By 1953, when WHYN-TV (now WGGB-TV) signed on from Mount Tom, only WHYN-FM was still transmitting from the mountain, as WMAS-FM had moved to the WMAS (now WHLL) tower in Springfield and WACE-FM had gone dark.

WHYN's long-time morning team consisted of Frank Knight and news man Ron Russell (DeMatteo).

Dan Williams was the longest continual employee of WHYN-AM-FM, having started in the mid-1970s when Guy Gannett Broadcasting was the owner.

After being purchased by Affiliated Communications, the station's format was switched to adult contemporary music geared towards an 18–54 female demographic.

At that point, Frank Knight and Ron Russell exited to be the morning team on Lapin Communications' 1450 WMAS for that station's "Music Of Your Life" adult standards format.

The IDs at the top of the hour quietly stated the Springfield city of license and the concept was that the station was "The Giant", a mythological entity broadcasting down to all the people of Southern New England.

Caringer stayed on as PD through the format change, eventually giving up the position when it became obvious he was no longer making management decisions, but simply an order taker from the consultant in Seattle.

Evening DJ Mary Ferrero, who lost her position to Strong, exited to become the production director at WMAS-AM-FM and Jennifer Fox took her place on WHYN-FM.

Due to budget constraints, the station fired her in late 2006[citation needed] and was replaced by the syndicated John Tesh show at night.
