Univision's over-the-air presence in Detroit makes Detroit/Windsor the only market in the United States or Canada with terrestrial stations in English, Spanish and French -- the French station is Radio-Canada affiliate CBEFT on channel 54, which rebroadcasts Toronto's CBLFT.
The station's master control is remotely originated via satellite from Equity's headquarters in Little Rock, Arkansas; Equity maintains a local news and advertising sales office at 5600 King Street in Troy. The station appears to have limited backup signal transmission arrangements; during several instances of bad weather, the WUDT-CA transmitter has sent simply a black screen or "NO SIGNAL" message.
On March 28, 2007, Comcast added WUDT to its Detroit lineup on channel 65, replacing the network's national East Coast feed, which had been carried since the 1980s when Comcast in the Detroit area was known as Barden Cablevision, and when Univision was known as Spanish International Network (SIN). However, it is still not available on WOW! Detroit, Bright House Livonia or Cogeco Windsor; WOW offers the national feed instead, however, Bright House does not have the station or the network on any of its lineups in Livonia, Farmington, Novi or Redford. Cogeco Windsor doesn't carry the network or the station due to restrictions set by the CRTC.
The station operates with an Effective Radiated Power of only 50 kilowatts with a directional antenna, covering the immediate Detroit and Windsor areas, plus large parts of southern Oakland and Macomb counties and small portions of Wayne and Essex counties.
The station took to the air on January 4, 1989, as low-power W05BN on channel 5. It then became WBXD-LP on September 1, 1995, and would later be acquired by Viacom in 2000, with the MTV2 music television network affiliation -- all of the properties have since gone to the new CBS Corporation after CBS and Viacom went their own separate ways, Viacom did keep MTV2. CBS is responsible for Detroit's only duopoly, CW affiliate WKBD 50 and CBS UHF flagship WWJ-TV 62. CBS also owns radio stations WWJ-AM 950, WXYT 1270 AM with simulcasts on WXYT-FM 97.1, WVMV 98.7 FM, WYCD 99.5 FM, and WOMC 104.3 FM.
Viacom later sold WBXD-CA to Equity Broadcasting, who then proceeded to rename the station WUDT-CA. The station went from MTV2 to Univision in a matter of hours. This move occurred on November 18, 2004. Again as mentioned, Viacom and CBS split very late in 2005. Viacom kept MTV2, but all the broadcast assets went to CBS Corporation. In 2007, Equity Broadcasting was renamed Equity Media Holdings Corporation.
The station applied for a license to operate digitally on VHF channel 8, putting it between the analog signals of WXYZ-TV on channel 7 and CBET on channel 9, which could cause some interference. This may also cause interference with Cleveland's WJW in the southeastern areas of Essex County, which has its analog signal on channel 8 as well. The application was filed and a construction permit was granted on October 10, 2007 and it expires on October 11, 2010.
