In May 1932, Albert S. Moffatt, a former newsreel photographer, was granted a construction permit by the Federal Radio Commission to begin work on a new radio station, with the sequential call sign WHEU. When the station officially signed on, its call letters were changed to WMAS.[2] The letters stood for Massachusetts, and they also include the owner's initials, although not in the correct order. The station's studios were in the Hotel Stonehaven, and when it signed on for the first time, on September 1, 1932, it broadcast on 1420 kHz with 100 watts.
In 1947, WMAS-FM signed on. At first, both stations mostly simulcast their programming.[3]
When network programming shifted from radio to television, WMAS-AM-FM switched to a full service, middle of the road music format. WMAS 1450 later had a country music format as "The Country Leader". On-air personalities included Dave Thatcher (also the station's news director), Fred Stevens, and Mike Williamson.
WMAS was one of the original "Music Of Your Life" adult standards radio stations, as its previous owner for many years, Bob Lappin (Lappin Communications, Inc.) was friends with the format's originator and syndicator, Al Ham.
On April 7, 2009, the format was changed to sports radio with programming from ESPN Radio. The call sign was changed to WHLL to represent the word "Hall". The Naismith Memorial Basketball Hall of Fame is located in Springfield and the station's studios were moved to the facility. Citadel merged with Cumulus Media on September 16, 2011.[6] After the merger, WHLL switched networks to CBS Sports Radio, a network that Cumulus Media had a financial interest in.
On December 27, 2018, WHLL changed its format from sports to country, branded as "98.1 Nash Icon", in line with the launch of an FM simulcast of WHLL on translator W251CT, which is licensed to Springfield.[7]
On February 13, 2019, Cumulus and Entercom announced an agreement in which WHLL and WMAS-FM, as well as WNSH in New York City, would be swapped to Entercom in exchange for Entercom's Indianapolis stations. Under the terms of the deal, Entercom began operating WHLL under a local marketing agreement (LMA) on March 1, 2019.[8] The swap was completed on May 9, 2019.[9] On March 22, 2021, WHLL rebranded as "Hall of Fame Country 98.1".[10]
On September 1, 2023, WHLL flipped to Spanish CHR, branded as "Nueva 98.1".[11]
