Augusta Amateur Radio Association will hold its annual Windsor Hamfest on Saturday, Aug. 20, at the Windsor Fairgrounds , Ridge Road, Windsor.

The event, which brings together amateur radio operators from Maine and New Hampshire, begins at 8 a.m., with vendors admitted at 7 a.m. for set-up.

There will be a large flea market of radio and computer-related items, and there is no charge to vendors. Vendors must supply their own tables and chairs. In case of rain, indoor space will be available.

Meetings for the Sea Gull Net, the Pine Tree Net and the Maine Slow Speed Net will be held at 9 a.m., followed by a testing session for all classes of FCC amateur radio exams at 10 a.m. The fee for the exams is $15, and applicants must provide two forms of identification, one of which is a photo ID. Copies of currently held amateur licenses and FCC certificates of successful completion must be provided; copies will not be returned.

Door prizes will be awarded at noon; winning ticket holders must be present to win.

Breakfasts and light lunches will be provided by the Whitefield Lions Club from its concession booth under the main grandstand.

The event has traditionally been held on the Saturday after Labor Day, but because the American Radio Relay League’s New England Convention is scheduled for that date in Boxboro, Massachusetts, the event was moved. The Windsor event is sanctioned by ARRL.

Admission will cost $5 for adults, and free for those younger than 16 when accompanied by a paying adult.
