According to mexicoradiotv.com, an excellent site by Texas TV board regular Fred Cantu, Nogales TV station XHNSS-TV has changed affiliations. The former Galavision affiliate is now affiliated with CadenaTres, whose flagship is XHTRES 28 Mexico City (formerly XHRAE). XHNSS brands itself locally as SieteNogales, or 7 Nogales, and seems to provide local news. Its branding is a little confusing in that XHFA-TV 2 Nogales brands itself as Azteca 7, after its primary station's dial position in Mexico City. XHNSS-TV has a Facebook page - www.facebook.com/canal7 - which it created on November 1 of last year, so I'm guessing the affiliation change occurred about that time as well. In addition to Nogales, Sonora, the station serves most of Santa Cruz County and reaches as far north as Green Valley.
