Probably not, as radio communications has come a long way in recient years. However, back in the 1990s, I was working in Louisiana when Hurricane Andrew hit, and Ham radio was the only game in town there. All of the public service and cell towers had gone down, and amateur radio operators were actually travelling with police and fire ofiicials to act as their communications. So, who knows. Let's hope we don't have to test it anytime soon.
