What Is Foxhunting?
Foxhunting (hidden transmitter hunting) participants attempt to find a hidden transmitter (the “fox”), using handheld or mobile directional antennas within a designated area. As a minimum, you will need a mobile or portable 2M radio and usually a directional antenna, although some hunters use multiple radios and specialized DF (direction finding) antennas. You can work alone or in teams to find the fox.
While foxhunting is fun on its own, it’s actually good practice for hams to be able to find malicious or unintended interference from other radio sources. It’s important to have a good team of trained “hunters” to nail down interference sources, and foxhunting is great training.
How To Get Started
As a minimum, all you need is a portable VHF/UHF radio (HT) or mobile radio with a car-mounted antenna. A radio that has a good S-meter (signal strength) will be helpful. You’ll probably also want a directional antenna (yagis and loops are popular options – see below for a cheap build-it-yourself tape measure yagi). Then just listen on the published frequency after the hunt is announced. If you hear the fox, use a combination of signal strength and a directional antenna to try to determine which direction it’s in relative to where you are. After a few receptions, you should be able to close in on the general location.
