Fox Hunt

Fox Hunting or T-Hunting (hidden transmitter hunting) or Radio Direction Finding.

Locating a radio transmitter, whether hidden, intermittent, interference-generating or just for fun can be a challenging sport. It tests your knowledge of radio theory, navigational skills, equipment operational skills and just plain detective skills.

Fox hunting can be as simple as walking around with a handheld HT to an elaborate suite of commercially-made radio direction finding equipment. It can cost no money at all to thousands of dollars. Many hams choose to build simple, low cost antennas and attenuators rather than buy them. Here are some web sites that may be of interest.

The bible of fox hunting is undoubtedly this one:
