In the meantime, we'll still have our Katrinas, Sandys (including those of the Hook variety), Fergusons, and other disasters whose effects will be amplified by the slow decay. You will still have a need, in our increasingly post-industrial idiocracy, of getting news and information about local happenings. Here is one more useful tool you can add to your kit. It contains a list of tactical frequencies that are generally only used when multiple public safety agencies have a need for interoperability (to talk to one another) during disaster response and mitigation. That means they are generally quiet unless something is happening.
Learn what you can. Acquire the necessary gear. Get ready. It's gonna happen, just not as quick as you think. Be thankful for that. It gives you more time.
The National Interoperability Field Operations Guide (NIFOG) is a technical reference for emergency communications planning and for radio technicians responsible for radios that will be used in disaster response. The NIFOG includes rules and regulations for use of nationwide and other interoperability channels, tables of frequencies and standard channel names, and other reference material, formatted as a pocket-sized guide for radio technicians to carry with them.
I would also peruse the other document selections at http://www.publicsafetytools.info/. They will become the basis for Version 2.0 of the workshops starting next year.
