Today is Field Day, the annual event where thousands of hams across the nation publicly demonstrate their emergency communication abilities. You can find hams constructing emergency stations in parks, schools, backyards and shopping malls operating using only emergency power supplies. If you are interested in getting started with ham radio but don’t have a license, today is a great day to do so. Field Day is one of the few opportunities when you can operate without a license at the GOTA (get on the air) stations (which are supervised by licensed hams).
You can find your local field day station on the ARRL Web station locator.
