21st IARU World ARDF Championships Announced

The Czech Radio Club has disseminated Bulletin 1 for the 21st IARU World ARDF Championships, which will be held August 27 to September 2, 2023 in Liberec, in the North Bohemia region of the Czech Republic. A training camp, consisting of courses in all four radio orienteering disciplines (foxoring, sprint, and 80m & 2m classic) will be held August 24-26.

Competitors representing the USA in the championships will be selected based on individual performances of competitors at USA Radio Orienteering Championships.

Same Sport, New-ish Name

An announcement from the ARRL ARDF Coordinators:

The name Radio Orienteering has been around for a very long time and has frequently been applied to the sport of ARDF, but it hasn't been recognized in any official sense. Because Radio Orienteering is more descriptive of the sport (especially to the orienteering community), and because Amateur Radio Direction Finding is often confused with other radio direction-finding activities (like mobile t-hunting), the ARRL ARDF committee has decided to officially favor the use of the term Radio Orienteering. We believe that a transition to that name will result in less confusion, and perhaps, quicker acceptance of the sport by orienteers and others who will more readily grasp the essence of the sport. So look for more references to Radio Orienteering going forward, and don't be confused: it is the same radio navigation sport we all enjoy, but with a more descriptive name.

About Radio Orienteering

In this sport there are no vehicles, traffic jams, or exhaust fumes. Radio Orienteering (aka, Amateur Radio Direction Finding, or 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 Radio Orienteering activities are growing, and ARRL provides encouragement and support for Radio Orienteering 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 Radio Orienteering competitions? There are World Championships held biannually, 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 Radio Orienteering Team USA.

The only way to ensure an invitation to join the team is to prove your mettle by competing in ARRL-sanctioned Radio Orienteering competitions such as the USA Radio Orienteering 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.
