The concession was awarded on November 30, 1988, and Mayans set out to build Tijuana's third TV station and second UHF, after XHAS came to air in 1981. Transmitter tests began in the summer of 1989 and the station was on air by 1990, with a schedule of music videos and some local programs including, in 1991, 25 San Diego Padres road games in Spanish and adding Spanish play-by-play to ESPN and TNT telecasts of NFL preseason contests. The music video programming, an outgrowth of sister XHMORE-FM 98.9, came to dominate the station's output, and channel 45 was known as "MORE TV" during the 1990s.
