The ARRL promotes and governs many Amateur Radio events. To learn about these contests go to the ARRL Home site, choose On The Air, then Contests, then Contest Calendar, and Contest Dates Calendar. The calendar will note the date and name of the ARRL sanctioned event. You can then find the requirements and more information about the event. Happy contesting!
In 2017 the Texas State Parks on the Air Event was April 8th and 9th. They camped and activated at Lake Whitney State Park, just a little west of Hillsboro. There were about 4 RV’s, plus a tent or two, all hams. It was a great weekend!
The SWDCARC participates in the annual ARRL Field Day which is held the fourth full weekend in June each year. Guests are welcome to come and observe or participate in this 24 hour event.
