I was active with ax.25 packet radio 20 years ago. What is actually useful is the ability to do this on HF radio. Here in South Texas I can connect to a gateway node somewhere in the country practically at any time and get a message out. Since the gateways are sometimes several hundred miles away, it would be impervious to any local disaster, provided I can get 12v at a few amps to run my gear.
