WKAF is a radio station in the Boston, Massachusetts market licensed to Brockton, Massachusetts, simulcasting the rock format of WAAF. It broadcasts on 97.7 MHz, and serves the Metro Boston and South Shore areas of Massachusetts, which are unable to receive WAAF's main 107.3 MHz signal.
WKAF first went on the air in 1948 as WBET-FM, the sister AM station of WBET/990 (now WXBR/1460) in Brockton (WBET would buy WBKA/1460 & WBKA-FM/107.1 & shut down 990 and 107.1). The two stations almost always simulcast programming for the next 28 years. On November 1, 1976, WBET-FM went Stereo and broke away from the AM to broadcast a Top-40 format. On January 1, 1977, the call letters were changed to WCAV. In July 1982, the station switched to country music and targeted the South Shore of Massachusetts. This format continued until 1999. For some of that time, WCAV was the only country-music station on the FM dial in the Boston area.
In 1999, WCAV was purchased by Radio One, a company that owns and operates radio stations which target African American communities. Radio One made many transmitter improvements and established new studios in Roxbury, a largely African American section of Boston. After weeks of dead air and a week-long stunt of a loop of Tone Lōc's "Wild Thing", the station was relaunched on December 6, 1999 as WBOT, "Hot 97.7", targeting the Greater Boston area with a Mainstream Urban format.
From the very beginning, WBET-FM/WCAV/WBOT had been plagued by a poor signal in Boston and points north. However, after the relocation of the transmitter to Great Blue Hill in Milton, Massachusetts in summer 2005, the station's signal improved dramatically.
WBOT had never made any significant strides against its main competitor, WJMN "Jam'n 94.5", a station which had no signal problem and depended chiefly on the region's large Caucasian population for success. At the same time, Radio One had been experiencing great success with the Urban Adult Contemporary/Urban Oldies format of WILD 1090, a weak AM radio station that was prohibited by FCC regulations from operating at night.
On October 20, 2005, Radio One moved the format and intellectual property of WILD to WBOT's FM signal. This move eliminated WBOT from the Boston radio dial, and created the new "97.7 WILD FM". WILD-FM had retained the Urban Adult Contemporary programming of the old WILD/1090 during the day, and aired the old WBOT's Mainstream Urban format during the late afternoon and early evening hours. The station officially changed call letters to WILD-FM on October 26.
There was speculation that the format of the old WBOT would be reborn if Radio One acquired a second FM station in the Boston area, but there was nothing to suggest that such a move would occur. The former "Hot 97.7" format was now airing on 97.5, before moving to 87.7 as a pirate radio station, until it was shut down in 2010. The group now maintains a web-only presence.
Entercom buys WILD-FM 
On August 21, 2006, AllAccess.com reported that Entercom had purchased WILD-FM and would change the format to rock (a simulcast of WAAF 107.3). The end of WILD-FM came after "Wild Thing" by Tone-Loc at about 7:00 pm EDT on August 21, and the station began a stunt of a computerized voice counting down to 5:30 pm EDT the following day, August 22. At that time, the simulcast of WAAF began with the song "For Those About To Rock (We Salute You)" by AC/DC. The station changed its calls to WKAF on August 30, 2006, reflecting the new simulcast.
The move has expanded the signal reach of WAAF to more of the urban areas of Boston and the South Shore cities and towns of Massachusetts. However, both WAAF and WKAF have signal issues in the South Coast and Taunton areas.
