 XEIMT ended its relationship with Imevisión in December 1991, leaving the air.The next year, the government announced the sale of the remainder of Imevisión, including the 7 and 13 networks; Televisión Azteca would buy both networks, creating its Azteca 7 and Azteca 13 networks from their infrastructure.In March 1993, XEIMT returned to air with test signals from a new transmitter location, Cerro del Chiquihuite, which offered vastly improved coverage of the Mexico City area.
