What is "xhopma-tdt"

XHOPMA-TDT is a digital-only television station in Mexico City, the flagship station for the Sistema Público de Radiodifusión del Estado Mexicano (SPR) transmitter system. It broadcasts on channel 30 from a transmitter atop Cerro del Chiquihuite; its primary signal is the SPR's Una Voz con Todos network.

XHOPMA signed on in 2012. Its transmitter is located on Cerro del Chiquihuite, which is home to the majority of Mexico City's broadcast stations. Not long after, the name of the OPMA network, originally "30 TV México", was changed to its current Una Voz con Todos, to reflect that it aired on different channels in each city.
