WKVB (107.3 FM) is a non-commercial radio station licensed to serve Westborough, Massachusetts, United States, carrying a contemporary Christian format known as "K-Love".

Owned by the Educational Media Foundation (EMF), WKVB does not broadcast any local programming but functions as the network affiliate for K-Love in Greater Boston and Worcester.

The station also featured personalities including Bob Rivers, Liz Wilde and Greg Hill, and was the first high-profile radio home for Opie and Anthony in the mid-1990s.

[3] On October 5, 1960,[4] the Federal Communications Commission (FCC) awarded the Waterman Broadcasting Corporation, owner of WAAB (1440 AM), a construction permit to build a new FM radio station licensed to Worcester on 107.3 MHz, to transmit from Asnebumskit Hill in Paxton.

[8] In later years, WAAF ownership would erroneously claim a longer history than that of its own license, stretching back to experimental FM station W1XOJ in the late 1930s.

[23] WAAF's third sale of the decade would come in 1978: the station, its AM counterpart WFTQ, and WEZN were sold to a group of employees, known as Park City Communications, for $3.2 million.

[19] Music heard on the station tended to lean toward a harder rock focus from artists like Led Zeppelin, Ted Nugent, Van Halen, and Pat Benatar.

It was during this time, in September 1981, that the Rolling Stones played a warmup show for a group of WAAF listeners at Sir Morgans Cove, a Worcester nightclub.

While WAAF refused to announce the name of the location, WBCN obtained the information from a Worcester police officer, causing a large crowd of 4,000 to form outside of the 300-seat venue; 10 people were arrested.

[29] WAAF promotion director Steve Stockman blamed WBCN for announcing the venue on-air, declaring his competitor's actions "reckless and irresponsible".

The station had also asked the town's fire chief to give the winner keys to the city; he declined, believing the initial offer to be a prank phone call.

On March 10, 1989, NewCity Broadcasting traded WAAF and WFTQ to Zapis Communications in exchange for WEKS-FM (104.1) in Atlanta in what was a tax-free asset swap; each half of the transaction was valued at $15 million.

"[54] Starting on January 9, 1991, WAAF's programming was simulcast over WFTQ due to what John Sutherland called "substantial losses" for the AM station's prior format;[55] among the people dismissed was Steve LeVeille.

As the station continued to evolve under the "Untamed Radio" brand, Liz Wilde was hired initially for evenings in 1990, then promoted to afternoon drive in early 1992.

[59] Following Ruby Cheeks' departure from WAAF to return to Cleveland at WNCX,[60] Greg Hill assumed sole hosting duties for what would be called The Hill-Man Morning Show.

Both Wilde and Hill's on-air presentations, in addition to billboards and television commercials suggestively promoting the station, netted attention in the local press for what was deemed as "raunchy" content.

[64] Every November, starting in 1993, WAAF held a popular annual charity event "Walk and Rock for Change", raising money for food banks in Massachusetts and New Hampshire.

[66] For the first two weeks of December 1993, Greg Hill engaged in an elaborate stunt dressed up as a "Mystery Santa", handing out $50 bills to random people and even to Boston Mayor Thomas Menino, who declined the money offer.

[67][68] Hill's reveal took place in a news conference after several days of $10,000 giveaways, including several hundred dollars to a homeless shelter, saying he was aiming to capture "the curiosity of the people".

[71] WAAF program director Ron Valeri tuned into WBAB while visiting family in Long Island and called Hughes to offer them a job.

[76] In May 1997, Hughes and Cumia started one of their most notorious promotions: "Whip 'em Out Wednesday", where women engaged in "flashing" to any oncoming drivers that had a "WOW" sticker on their car.

[84] While the FCC took no action,[83] the negative reaction caused American Radio Systems (which had purchased the station, along with its AM counterpart, for $24.8 million on August 1, 1996)[85] to fire the duo and suspend Mittman for one month and Douglas for a week.

The competitiveness was especially notable as WBCN had several distinct advantages over WAAF: a signal centered in Greater Boston, the local rights to The Howard Stern Show, and the flagship station designation for the New England Patriots Radio Network.

[91] Due to both American Radio and Infinity having multiple station holdings in the Boston market, Entercom purchased WAAF and WWTM, along with WEEI (850 AM), WRKO, and WEGQ, from the combined entity for $140 million on August 14, 1998.

[99] Mistress Carrie, who has never publicly disclosed her surname, applied to be a producer for Opie and Anthony right before their dismissal in 1998, but was still hired full-time to the evening shift;[100] her involvement at the station dated back to a college internship seven years earlier.

[3] Despite the K-Love network affiliation agreement having been officially signed four days earlier, on a Friday, Mistress Carrie and Mike Hsu were not informed of the transaction until two hours before the press release was issued, in between both of their respective airshifts.

Among the in-studio guests was Aerosmith bass player Tom Hamilton, who personally reminisced about the first time he heard Dream On played anywhere on radio while driving in his car, listening to WAAF.

[133] Other guests on the program included Bob Rivers, Peter Zipfel, Greg Hill, Gregg "Opie" Hughes, Anthony Cumia, and Rebecca Pratt.

[145] In July 2022, EMF purchased a second Boston-area station, WBOQ (104.9 FM) in Gloucester, to bring K-Love programming to portions of Boston's northeast suburbs not served by WKVB.

[148] WKVB does not air local programming; all content is transmitted via satellite by the Educational Media Foundation's K-Love network based out of Rocklin, California.
