Amateur radio, or ham radio, is one of those things where you get it or you don’t.

But the American Radio Relay League hopes that a few more people get it after this weekend’s National Field Day, described as “part educational event, part operating event, part public relations event—and all about fun!” The event is part of the league’s Amateur Radio Week.

The idea behind National Field Day is for ham radio operators to show off and demonstrate their radios to the public while attempting to see how far their devices can reach. The event tends to draw emergency department staff, who often use ham radio as a secondary communication option. John Zabriskie Sr., assistant director of the Charlestown, Rhode Island, Emergency Management Agency, noted that the tests work as a nice refresher for employees.

“The field day demonstrations keep our teams in Westerly and Charlestown in sync,” Zabriskie told The Westerly Sun on Thursday. “We test our radios locally and long-distance — this keeps our teams sharp.”
