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. 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. During the 1940s and 1950s, WMAS was a member of the Yankee Network, a programming service originating in Boston for New Englandradio stations. WMAS was also a CBS Radio Network affiliate. It carried the CBS line-up of dramas, comedies, news, sports, soap operas, game shows, children's shows and big band broadcasts, during the "Golden Age of Radio." In 1947, WMAS-FM signed on. At first, both stations mostly simulcast their programming. 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, 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 was friends with the format's originator and syndicator, Al Ham. In June 2004, WMAS-AM-FM were sold to Citadel Broadcasting for $22 million. Citadel switched AM 1450 to an unsuccessful talk radio format, then tried oldies, playing Scott Shannon's The True Oldies Channel from ABC Radio. On April 7, 2009 the format was changed to sports radio with programming from ESPN Radio and the call sign was changed to WHLL. Citadel merged with Cumulus Media on September 16, 2011. After the merger, WHLL switched networks to CBS Sports Radio. Cumulus Media has a financial interest in the CBS SportsRadio Network. ESPN Radio programming is now heard in the Springfield area on WUCS 97.9 MHz. 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. 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 on March 1, 2019. The swap was completed on May 13, 2019.
