XHTM-TDT is a television station licensed to and broadcasting from Altzomoni, State of Mexico on virtual channel 10. Founded in 1952, it was the second television station built outside of Mexico City and the first relayer.
XHTM, along with Canal 5 transmitter XEX, serves one of Mexico's largest television service areas with a string of transmitters stretching from Taxco de Alarcón, Guerrero to Tlaxcala, Tlaxcala, including transmitters in Pachuca, Hidalgo, Cuernavaca, Morelos and San Martín Texmelucan, Puebla. XHTM's digital transmitter was initially located at Televisa's Puebla transmitter site along with the digital operations of its Altzomoni sister stations and both analog and digital signals of Televisa's Puebla independent XHP-TV; in 2015, final digital facilities were built on Altzomoni, coinciding with a power increase from 45 kW to 236.
