Programming on XHUNAM generally consists of educational telecourse programs for UNAM students, plus public affairs, documentary and cultural programming. Some XHUNAM programming can also be seen on the nationwide Edusat service.
XHUNAM began broadcasts on analog channel 60 on December 5, 2000, where it broadcast for five years. On November 30, 2005, however, XHUNAM launched its digital signal, one of the first in the country and also one of the first digital-only stations in Mexico. Despite having channel 60 as its analog channel, TDT channel 20 has no virtual channel information.
XHUNAM is generally on the air daily from 8AM to as early as 12 Midnight (longer on some nights, especially if there's a movie or concert scheduled).
At a power of 200 watts, XHUNAM generally covers only the greater UNAM area in Mexico City, though it had coverage on cable providers and SKY México nationwide. It received a major coverage boost with the launch of the Organismo Promotor de Medios Audiovisuales digital transmission network: almost all of its transmitters carry teveunam as their fifth subchannel, and its full-power Mexico City station, XHOPMA-TDT, carries it as digital subchannel 30.2.
