WUMP (730 AM, "SportsRadio 730 The UMP") is a commercial radio station licensed to Madison, Alabama, and serving the Huntsville metropolitan area.

Part of the UMP's affiliation with Westwood One allows the UMP to carry a large package of NCAA basketball games, the March Madness tournament, the NCAA Division I Men's Ice Hockey Tournament, the College World Series, the Women's College World Series and select NHL games, including the Winter Classic and the NHL Playoffs concluding with the Stanley Cup.

[1] With new ownership, new call letters, a new frequency, and increased power in place, the station changed to an urban contemporary format branded as "D-73".

[12] In April 1989, Vascular Diagnostic Labs bought out the previous shareholders of Excelsior Broadcasting Corporation, the licensee for this station.

[13] In August 1989, with the financial issues resolved and the previous shareholders bought out, Excelsior Broadcasting Corporation was dissolved and the license was involuntarily transferred to Vascular Diagnostic Labs owner Dr. Merlin Kelsick.

[14] The call letters were changed to WBBI on August 19, 1991,[1] after Dr. Merlin Kelsick completed a deal to sell the station to Phoenix Capital Corporation.

[1] In June 1993, Phoenix Capital Corporation reached an agreement to sell WKMW to Madison Radio Company, Inc.

[1] The new call sign was chosen to match the station's new sports radio format and branding as "The Ump", an abbreviation of umpire.

The Dunnavant family of Athens owned the station from the early 1990s until agreeing to sell it to Cumulus Broadcasting in 2003.

[21] WUMP remains co-owned with former Dunnavant stations WVNN and WZYP, in addition to WHRP and WWFF-FM.
