Amateur Radio Direction Finding (ARDF), also known as "fox hunting," is a popular outdoor sport and amateur radio activity that involves using radio equipment to locate hidden transmitters. The objective is to find the location of the hidden transmitters as quickly as possible, using only radio direction-finding techniques.

ARDF is a challenging activity that requires a combination of physical fitness, radio knowledge, and navigation skills. Participants use a portable radio receiver and directional antenna to pick up signals from the hidden transmitters, and then use their knowledge of radio propagation and direction finding to determine the location of each transmitter.

The hidden transmitters, also known as "foxes," are typically small, low-power radio beacons that transmit at a specific frequency. They are often hidden in a wooded area or other challenging terrain, requiring participants to use their navigation skills to locate them.

ARDF is a popular activity among amateur radio enthusiasts, especially in countries like Russia and other former Soviet Union countries where it has been an organized sport for decades. It is also gaining popularity in other parts of the world, including the United States, where it is often used as a training activity for emergency response personnel and search and rescue teams.

ARDF is a fun and challenging activity that combines radio communication, navigation, and physical fitness, and is a great way for amateur radio enthusiasts to test their skills and have fun outdoors.


WiFi Amateur Radio Direction Finding, also known as Fox Hunting, is a game or sport that involves using radio direction-finding techniques to locate a hidden transmitter (also known as a "fox"). In this case, the hidden transmitter uses a WiFi signal rather than a traditional radio signal.

The game typically involves two or more teams of radio amateurs who use handheld directional antennas and portable receivers to track down the location of the hidden transmitter. The first team to locate the transmitter wins the game.

The use of WiFi signals in this game is relatively new, and it presents some unique challenges compared to traditional radio signals. WiFi signals can be affected by interference from other signals, obstacles such as buildings and trees, and other environmental factors. This makes the game more challenging and requires the participants to be more skilled in radio direction-finding techniques.

Fox Hunting is a popular activity among radio amateurs, and WiFi Amateur Radio Direction Finding adds a new twist to the traditional game. It can be a fun and educational way to learn about radio communication and direction-finding techniques while also providing an opportunity for outdoor activities and team building.




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.
