Amateur radio direction finding (ARDF, also known as radio orienteering, radio fox hunting and radiosport) is an amateur racing sport that combines radio direction finding with the map and compass skills of
orienteering. It is a timed race in which individual competitors use a topographic map, a magnetic compass and radio direction finding apparatus to navigate through diverse wooded terrain while searching for radio
transmitters. The rules of the sport and international competitions are organized by the International Amateur Radio Union. The sport has been most popular in Eastern Europe, Russia, and China, where it was often used
in the physical education programs in schools.
For many of our events we use WiFi foxes so that the youth can use their cellphone as a detection/range tool.
With dedicated higain directional antenneas and receivers youth can triangulate transmitter positions from a distance. This game combines BSA Orinteering skills along with math, radio and topology.
ARDF events use radio frequencies on either the two-meter or eighty-meter amateur radio bands. These two bands were chosen because of their universal availability to amateur radio licensees in all countries. The radio
equipment carried by competitors on a course must be capable of receiving the signal being transmitted by the five transmitters and useful for radio direction finding, including a radio receiver, attenuator, and
directional antenna. Most equipment designs integrate all three components into one handheld device.
