ARDF Enthusiasts Compete In USA National Championships:

Fifteen US-eligible competitors took home first-place awards in the just-completed 17th US National Championships of Amateur Radio Direction Finding (ARDF) in Harrison, Ohio. The competition ran from August 3 through 6 on the 4,345-acre Miami Whitewater Forest and other nearby wooded sites, and it attracted more than 80 fans of the sport -- also known as foxtailing and radio-orienteering. This year's USA Championships were combined with the 9th ARDF Championships of International Amateur Radio Union Region 2 (IARU R2 -- the Americas. The IARU establishes rules for ARDF competitions The object is always to find as many of the required transmitters as possible in the shortest amount of time, and then navigate to the finish line. Competitors may use only their own direction-finding equipment, in addition to a compass and the provided map.

Classic 80- and 2-meter competitions with up to five hidden transmitters took place on separate days. Course lengths -- from start to each required transmitter and then to the finish -- ranged from 2.8 to 7.1 kilometers (1.7 to 4.4 miles), depending on age/gender category.

Two additional events took place, both on 80 meters. These included the sprint -- a shortened course with 10 transmitters and a faster transmitter cycle -- and foxoring, a combination of orienteering and foxhunting, in which participants receive maps marked with the approximate locations of a dozen very low-power transmitters to find. In all events competitors are divided into six age categories for men and five for women, with medals awarded to winners in each category. The 4 days of championship events were preceded by 3 days of informal training in other nearby parks.

According to IARU rules, US-eligible competitors must be either citizens or legal residents for at least 1 year.

Organizing and staging the championships were members of the OH-KY-IN Amateur Radio Society. Additional volunteers were members of Orienteering Cincinnati (OCIN), which also provided the event maps.

Complete results of all events in these Championships are available on the Homing In website, where there is also much more information about the growing sport of ARDF. Read more -- Thanks to Joe Moell, K0OV, ARRL Amateur Radio Direction Finding Coordinator
