[2] WFNK has an effective radiated power (ERP) of 100,000 watts, broadcasting from a transmitter in Poland, Maine, making it among the highest-powered FM stations in New England.

WFNK is also known for its long-running campaigns in support of Portland's Barbara Bush Children's Hospital and Maine's Make-a-Wish chapter.

DJs were given the freedom to choose whatever rock albums they wanted to play and discuss topics in music, politics and lifestyles they felt motivated to cover.

[4] In December 1989, WBLM switched call signs and frequencies with WTHT and became "Thunder 107", airing a contemporary hit radio format.

[5] Since its founding, the station was hard to hear in parts of Portland and its suburbs, due to its 30,000-watt tower located 25 miles north of Maine's largest city.

On April 6, 2004, WTHT began running a continuous recorded loop directing listeners to 99.9 FM, where "The Wolf" was relocated.

The station launch was backed by numerous TV commercials and other promotions, with WFNK quickly becoming a ratings success in the Portland radio market.
