About ARDF

In this sport there are no vehicles, traffic jams, or exhaust fumes. ARDF brings radios into the great outdoors with maps and compasses, providing a uniquely enjoyable way to learn new radio skills. This radio sports activity deals with the taking of radio bearings to navigate through wooded areas in search of transmitters. It involves constructing direction-finding equipment, training amateurs in the rules of the sport, and organizing events in the USA and other IARU countries.

Interest and participation in ARDF activities are growing, and ARRL provides encouragement and support for ARDF activities across the United States. Events often take place at amateur radio conventions and hamfests as a magnet to amateur radio for youth and others. Championship competitions are held annually to help decide membership on the US team at the ARDF World Championships.

Join Team USA!

Would you like to represent the USA at international ARDF competitions? There are World Championships held on even-numbered years, and World Youth ARDF Championships (WYAC) have been held annually since 2017. Citizens of the USA, Green Card holders, and those who have lived in the USA for the previous year and have not competed for the title of Champion in any other country during that time, are eligible for membership on ARDF Team USA.

The only way to ensure an invitation to join the team is to prove your mettle by competing in ARRL-sanctioned ARDF competitions such as the USA ARDF Championships. But occasionally there are open team positions available that can be filled by qualified individuals lacking competitive results. A limited number of non-competing visitors may also travel with the team. USA Team members and visitors are responsible for all expenses associated with their participation, including paying for their own transportation, room, board and entry fees. Contact the ARRL ARDF Committee for full details.
