WYXB (105.7 FM), branded as "B105.7", is a commercial radio station owned by Urban One in Indianapolis, Indiana.

The founders formed "The Fine Arts Society of Indianapolis" in 1968 to keep classical music on the radio but no longer dependent on advertising dollars.

The call letters on 105.7 FM changed to WTLC on January 22, 1968, and flipped to an Urban Contemporary format.

The station switched to adult contemporary, playing the softer hits of the 1980s, 90s and current AC music.

[5] On June 13, 2022, Emmis announced it would sell its entire cluster of radio stations in Indianapolis to Urban One.

Studios for Urban One stations in Indianapolis, WLHK, WIBC, WFNI, WTLC, WTLC-FM and WYXB are on the southwest quadrant of Monument Circle.
