WTMJ radio, WKTI and WGKB moved to a new studio within the Third Street Market Hall in downtown Milwaukee at the end of 2022.

In addition to a standard analog transmission, WKTI broadcasts in HD Radio and rebroadcasts their AM sister station on its second subchannel.

[2] In May 1940, the Federal Communications Commission (FCC) announced the establishment, effective January 1, 1941, of an FM band operating on 40 channels spanning 42–50 MHz.

This original WTMJ-FM, along with co-owned WSAU-FM in Wausau, ended operations on April 2, 1950, with their licenses turned in to the FCC for cancellation.

[7] A second WTMJ-FM, predecessor of the current station, commenced operations on June 1, 1959, at 94.5 FM, and ran beautiful music programming for the next 15 years.

To support the new brand, the owner wanted to change the station's call sign but could not decide on the two middle letters of a new name.

The station manager, Jack Lee, proposed "WWWI", but the airstaff was not comfortable about using the tongue-twisting call letters on-air.

However, slow adjustments were made to WKTI's playlist, changing to an Adult Top 40 format to attract new and younger listeners.

In late 2006, Bob Reitman semi-retired, moving on to a weekly program on local public radio station WUWM.

Cindy Huber hosted the evening program for two years, but then left the station in a reshuffle and moved to WLDB.

For example, the Milwaukee Brewers Sunday broadcasts moved to WKTI to allow Green Bay Packers radio play-by-play reports to air on WTMJ.

[11] On July 22, 2010, WLWK aired a Brewers game to allow WTMJ's coverage of a sudden flash flood emergency.

[12] At 12:12 p.m. on November 6, 2008, after playing "Damn, I Wish I Was Your Lover" by Sophie B. Hawkins and "Hello, Goodbye" by The Beatles, Journal Broadcast Group general manager Steve Wexler went on WKTI to introduce listeners to a complete makeover for 94.5 FM.

The WKTI call sign then moved to the Sturgeon Bay/Door County channel 22 translator for WGBA-TV in Green Bay.

From July 8, 2009 to October 1, 2011, WTMJ-TV's third digital subchannel carried the music network TheCoolTV; the affiliation was co-branded with Lake FM.

An announcement followed the end of Side 1 from Scripps Milwaukee Radio's Vice President and General Manager Tom Langmyer thanking listeners of The Lake (and revealing the "Abbey Road" move was intended as a tribute to how the station launched) and notifying them about a forthcoming format change.

[21][22] In November 2017, after only two-and-a-half years, WKTI surpassed WMIL to become the radio market's top-rated country station with listeners 6+ according to the Nielsen Ratings.

At that point, with the competition no longer presenting a challenge, WMIL returned to its previous default leadership position, albeit with lower ratings than it had before WKTI became a country station.

WKTI was a country start-up station beginning with no audience, before eclipsing WMIL, the market leader, within a very short period of time.
