During the last week of Nov 2010 IS-14 just went dead (at least on my location, El Salvador). Eventually it came back, but the Puerto Rico Mux on 3946h, 14450 7/8 is no longer accesible. Can anyone confirm what I am experiencing, or better yet does anyone know if the PR mux has changed? I know of other guys in my country who are experiencing the same trouble. Thanks in advance.
