XHUAA-TDT

XHUAA-TDT, virtual channel 57 (UHF digital channel 22), is a television station located in Tijuana, Baja California, Mexico, whose over-the-air signal also covers the San Diego, California area across the international border in the United States. The station is owned by the Grupo Televisa; it is an affiliate of El Canal de las Estrellas. XHUAA began broadcasting in digital on UHF 22 in early 2006 making it the second station in Tijuana (and at the time one of very few in Mexico) to have a digital signal (sister station XETV was the first).

XHUAA signed on in 1990; its original concessionaire was Radiotelevisora de La Rumorosa, S.A. de C.V.

By then-current Mexican law, XHUAA was suggested to start broadcasting digital television by January 1, 2010, although this station was allowed at its discretion to start broadcasting DTV before law required it to, and XHUAA-TDT had signed on in 2006. The original assignment was channel 20, but the chosen channel caused issues to land mobile services in Los Angeles, prompting the FCC in the United States to request a channel change.
