It operates from studios at Audacy's Buffalo offices in Amherst, New York, with a transmitter located southwest of Warsaw.

[2] Perhaps at least partly because of the station's unique ability to cover both the Buffalo and the Rochester radio markets with one rimshot signal, WLKK is known for its frequent format changes.

The FM station on 107.7 at Wethersfield originally started broadcasting June 6, 1948 as WFNF, a member of the Rural Radio Network based in Ithaca.

One of its longest-running formats, country on WNUC (under the ownership of John Casciani) ran from August 31, 1992, to October 2000, when the station was sold to Adelphia Communications for $5,600,000.

Between October 2000 and April 2004, Empire Sports Network, under VP/GM Bob Koshinski, operated the radio station, aimed at fans from Western New York into the Finger Lakes.

Later additions would include Jim Brinson, Doug Young (who defected from WGR and is widely credited as the person who landed the interviews and guests that made WNSA so popular), and Zig Fracassi, who had been a nationally syndicated host until the dissolution of the Sports Fan Radio Network.

Jim Kelley, Mike Robitaille and Schopp (later replaced by Simon) hosted a two-hour show known as The Sharpshooters prior to Buffalo Sabres games.

Other unique features included "Superfan," a humorous short-form serial about a Buffalo sports fan endowed with superpowers, and "Haseoke," a feature in which audiotapes allegedly from Sabres goaltender Dominik Hašek singing karaoke were played on-air (poking fun at Hašek's thick Bohemian accent).

During Empire's ownership, 107.7 added its first Buffalo-area translator, W297AB in Williamsville, to improve the station's signal quality in Buffalo and the inner-ring suburbs.

That resulted in the retirement of Art Wander, the defection of Mike Schopp to WGR and part-time work at ESPN Radio.

The end of WNSA came when the station was sold to WGR's owner, Entercom Communications, in May 2004 for $10.5 million, and announced an immediate format change.

Several hundred hours of WNSA's programming, including several unique specials, were archived by producer Steve Cichon and are available for purchase.

The station indirectly took aim at the classic rock market and sought to create a more laid-back, relaxed atmosphere.

Disc jockeys, which included Hank Dole and Lorne Hunter, occasionally told the story behind the song (sometimes from CD liner notes).

[11][12] Beginning in 2014, the station began holding an annual alternative music concert series called Kerfuffle.

[13][14] On September 13, 2020, WLKK/W284AP quietly rebranded as "Alt 107.7/104.7", as part of a systemic "revamping" of Entercom's alternative rock stations.

[18] Liz Mantel, who had spent six of the previous eight years at WYRK, was the first local personality hired for the station, becoming the morning host in September 2021.

In April 2024, Audacy indicated plans to continue operating the digital-only "Star 102.5" when it included the channel among a suite that would begin using Super Hi-Fi AI-powered automation.
