Except during the Gatlinburg, TN wildfire last November... For many years, the quote "When all else fails... Amateur Radio", has been used to point out that ham radio can assist during emergencies. This is excerpted from The Tennessean this morning. It was part of the story "Records show chaos, confusion". I think it says a lot about how bad the situation became: "The $120 million statewide Motorola radio system used by the Tennessee Highway Patrol and the departments of correction and transportation failed to perform. Even ham radio systems weren't available." So much for the guys running around with yellow vests and 3 or 4 HTs on their belt saving the world. Repeaters were probably out of service, but simplex voice or packet might have been helpful. Many repeaters are co-located with public service sites so if the equipment building burns, or the power goes off with no backup, ham repeaters are also dead.
