WNML (AM)

However, 990 AM is a Canadian clear channel frequency, so at night, to avoid interference with other stations, WNML uses a directional antenna with a four-tower array.

The first formal regulations establishing radio broadcasting in the United States were adopted by the Department of Commerce effective December 1, 1921.

A notice in the October 3, 1922, issue of the Knoxville News reported that: "The Peoples' Telephone and Telegraph Company is experimenting with its new radio broadcasting station.

"[5] Peoples' was a local Knoxville telephone company, and after the initial tests proved successful, it was issued its first station license on November 3, 1922.

[11] Two months later, in late October 1925, the station was destroyed by a major fire on the roof of Peoples' Telephone and Telegraph.

[13] Later that month it was announced that the rebuilt station would be located atop the Sterchi Brothers building near the Gay Street viaduct.

[16] The station's frequency changed many times, eventually settling at AM 990 in March 1941 with the implementation of the North American Regional Broadcasting Agreement.

[18] Seeking a bigger performance area, WNOX moved its studios to Whittle Springs Road in north Knoxville.

So sure of getting the Channel 10 license, the company poured thousands of dollars into the Whittle Springs building to make it a top-notch radio-TV studio combination.

After the FCC awarded the TV license to Jay Birdwell, local owner of WBIR AM and -FM in 1956, Scripps-Howard was saddled with a huge studio to ultimately be used just for radio, amid a dwindling live listening audience.

Within a few years, WIVK 990 began adding some talk radio programming, eventually transitioning to an all-talk format.

Beginning in 2023, a change in the daily lineup was announced with the debut of “Tyler Ivens and Will West" in afternoon drive time.
