Do not fill this in! === Mexico === All digital television stations in Mexico have '''-TDT''' callsign suffixes. Analog stations, which existed until December 31, 2016, had '''-TV''' callsign suffixes. The equivalent of low power or translator service in Mexico is the ''equipo complementario de zona de sombra'', which is intended only to fill in gaps between a station's expected and actual service area caused by terrain; a station of this type shares the callsign of another station. In analog, these services often were broadcast on the same or adjacent channels to their parent station, except in certain areas with tight packing of television stations (such as central Mexico). In digital, these services usually operate on the same RF channel as their parent station, except for those with conflicting full-power applications ([[XHBS-TDT]] Cd. Obreg贸n, Son., channel 30 instead of 25), in certain other cases where it is technically not feasible ([[XHAW-TDT]] Guadalupe, NL, channel 26 instead of 25) or to make way for eventual repacking on upper UHF ([[XHPNW-TDT]] has four shadows on 33, its post-repacking channel, instead of 39). ''Equipos complementarios'' can relay their parent station, or a station that carries 75% or more of the same programming as its parent station.<ref>[http://www.ift.org.mx/sites/default/files/2016-12-30dof-diariooficialdelafederacion.pdf IFT: Disposici贸n T茅cnica IFT-013-2016 "Especificaciones y requerimientos m铆nimos para la instalaci贸n y operaci贸n de estaciones de televisi贸n, equipos auxiliares y equipos complementarios"], which became effective on January 1, 2017, provides the guidelines for the operation of digital television stations and their shadows.</ref> Stations of either type may have unusually low or high effective radiated powers. [[XHSMI-TDT]] in Oaxaca is licensed for two watts in digital. The highest-powered shadows are [[XEQ-TDT]] Toluca and [[XHBS-TDT]] Ciudad Obreg贸n, both at 200 kW.
