Members of the Cape Ann Amateur Radio Association, 6 Stanwood St., Gloucester, will participate in the national Amateur Radio Field Day exercise from 2 p.m. June 22 to 2 p.m. June 23.

Since 1933, ham radio operators across North America have established temporary ham radio stations in public locations during field day to showcase the science and skill of amateur radio. This event is open to the public and all are encouraged to attend. Field day is a showcase for how amateur radio works to create an independent communications network.

“Ham radio functions completely independent of the Internet or cell phone infrastructure, can interface with tablets or smartphones, and can be set up almost anywhere in minutes. That’s the beauty of Amateur Radio during a communications outage,” said David Isgur, communications manager for American Radio Relay League. “In today’s electronic do-it-yourself environment, ham radio remains one of the best ways for people to learn about electronics, physics, meteorology and numerous other scientific disciplines, and is a huge asset to any community during disasters or emergencies if the standard communication infrastructure goes down.”

Anyone may become a licensed Amateur Radio operator. There are more than 725,000 licensed hams in the United States.
