About Foxhunting

Foxhunting is a radio activity which involves searching for a transmitter using direction finding techniques. Also known as amateur radio direction finding (ARDF) Foxhunting is one form of Radiosport and is “popular in Eastern Europe, Russia, and China, where it was often used in the physical education programs in schools.” ¹

The skills practiced by Foxhunters are useful for locating Radio Frequency Interference (RFI) sources and Emergency Locator Beacons.
