ARDF - one of the last great adventures

What is ARDF ?
ARDF Amateur Radio Direction Finding . Also known as a FOX HUNT, it is closely related to the sport of orienteering. With orienteering, competitors run with the help of a compass to the points indicated on a

map. In a foxhunt, up to 5 small transmitters are hidden in a wooded area which the participants need to locate using a radio-directional receiver, a map and compass. To make the hunt more interesting, the transmitters send signals in succession. For example, if 5 transmitters are hidden, each one transmits for one minute at 5-minute intervals.

Who can take part?

Everyone. However, a little technical knowledge, good directional skills and stamina are an advantage. Since the direction finding equipment is only a receiver, no amateur radio licence is necessary. There is no age restriction. The whole family can take part, from Grandfather to Grandchild. Anyone interested can turn up to the next local club event, such as the ones we hold here at the OV V19 Hagenow. Individuals can decide whether to take the foxhunt at a leisurely pace or strive for first place. There are foxhunts of all sizes, from small OV Fox Hunts to world championships.

Where can I learn ARDF?

The foxhunts for OV-level represent best opportunity. Other participants and organisers will always be happy to help with technical and tactical advice. In addition, local radio clubs frequently hold talks on the subject. The beginner does not necessarily need a DF receiver to begin with as there are often spare receivers that can be borrowed at the meetings.

How does an ARDF event work?

Up to 5 small transmitters are hidden in a wooded area which transmit alternately for a 1-minute period. So transmitter 1 will be active for the first minute, transmitter 2 for the second minute, then transmitter 3, with the sixth minute being transmitter 1 again. Different signals will be coming from different directions. In addition to the directional receiver and compass the participant has a detailed map of the area, supplied by the organiser. Competitors start in small groups from certain points on the map. At each transmitter location, competitors mark their map with a hole-punch as proof of a successful find. Each foxhunt has a time limit, which should not be exceeded. It is better to miss a transmitter than run over time. The winner is the one who finds the most transmitters in the shortest time.
