WKHT (104.5 FM) is a rhythmic Top 40 station based in Knoxville, Tennessee.

This station signed on in November 1991 as WEMQ, later on as WQBB-FM, airing the same programming as adult standards WQBB.

In less than two years on the air HOT 104.5 forced its competitor WILD 98.7/WYIL to change formats.
