I believe that these days what hams have traditionally provided is largely irrelevant and redundant in many parts of the country. However there is one
unique service that hams can provide during a local disaster. That is email via Winlink on HF. It is the "new relevancy" in an era when cellular and internet service might be non-existent or very spotty, yet voice coms may well still be intact.
Here in District 1 of NW Indiana we are in the process of setting up six or more portable HF systems for rapid deployment that will provide Winlink for the EOC and other relevant agencies during an emergency. We can allow the 'client' to compose their own email(s), then the ham operator will send it on its way. The operator can also print out any incoming email(s) for the client as well.
We set up an HF/Winlink station out in the field during a recent SET exercise in less than 15 minutes, and handled many test 'emails' during the exercise!
