Some updates from the Arizona/Sonora border:
In Agua Prieta, XHAPS is broadcasting Telemax HD on RF 22, virtual 12.1, and is no longer putting out an analog signal on channel 12. XHAPT 17 is still broadcasting Canal de las Estrellas in analog, observed at about 6:15 pm MST. Analog shutoff is December 11, so XHAPT must be digital by next month - likely on RF channel 17, its final digital assignment, rather than on its interim digital assignment, channel 39.
In Naco, XHNAC has Telemax HD on RF 33, virtual 7.1; analog XHNAC was off the air. It is the town's only TV station, so analog shutoff has already come to Naco.
In Cananea, XHCAN has Azteca 7 HD on RF 25, virtual 4.1. No analog signal was detected. XHCCS and XHCNS also broadcast in Cananea, but I was not able to pick up either station in either digital or analog format. I have picked up XHCNS in analog on channel 56 in the past. Analog shutoff is still scheduled for December 31.
In Nogales, XHFA has Azteca 13 HD on RF 15, virtual 2.1, XHNSS has Cadena Trés on RF 31, virtual 7.1, XHNOA has Azteca 7 HD on RF 24, virtual 22.1 and XHNOS has Canal de las Estrellas on RF 41, virtual 50.x. Each of the above stations, except for XHNSS, is also broadcasting an analog signal on its original channel. XHNON, the Canal 5 station, is broadcasting exclusively in analog on channel 38, observed at about 10:00 pm MST. Analog shutoff is still scheduled for December 31.
