WTSJ-LD (channel 38) is a low-power television station in Milwaukee, Wisconsin, United States, owned by Innovate Corp. The station's transmitter is located at the Milwaukee PBS tower on North Humboldt Boulevard in Milwaukee's Estabrook Park neighborhood. History Early license establishment WTSJ-LD has its origins in a construction permit for a low-power television station on channel 55 in Ludington, Michigan, which the Federal Communications Commission (FCC) granted to Richard L. Bourassa on May 31, 1995 and issued the call sign W55CG. Bourassa sold the station to MS Communications on November 16, 2000. A month later, MS filed for a license to cover the permit, which was granted on February 16, 2001; on May 24, the company obtained a construction permit to move the station to channel 53 in Milwaukee as W53CC. The channel 53 permit was subsequently replaced with one for operation on channel 38 (as W38DT) on April 14, 2004. MS Communications had plans to establish wireless cable networks, but never broadcast anything other than test patterns on its stations. Bustos era with Azteca Bustos Media purchased the station from MS Communications for $1,350,000 on June 9, 2006. MS had shut down the W55CG facility in Ludington on the previous day in preparation for the completion of the sale. Bustos changed the call letters to WBWT-LP on August 30, 2006, built the channel 38 facility in Milwaukee, began airing a test pattern in September 2006, and officially signed WBWT-LP on the air on December 12. The station originally served as an affiliate of Azteca América and also initially carried a video simulcast of the morning program from sister radio station WDDW (104.7 FM). It expected to add additional local programming to serve Milwaukee's Hispanic community. Time Warner Cable began carrying the station throughout its service area in October 2009 on digital cable channel 807. Bustos filed for a construction permit with the FCC to build digital transmitter facilities on UHF channel 31 in 2010. In September of that year, Bustos transferred most of its licenses to Adelante Media Group as part of a settlement with its lenders. Switch to MundoFox On July 25, 2012, Adalante announced that it had signed an affiliation agreement to switch its Azteca America affiliates to upstart Spanish-language network MundoFox, which officially launched on August 13. However, WBWT-LP switched to the network two weeks earlier on August 1 during its unadvertised soft launch period. Azteca's national
