FOXHUNTING
what is foxhunting? |
Also known as T-Hunting, Transmitter Hunting and DFing, the main idea
is to track down transmitter(s) causing harmful interference to your
home station or repeater. Quite often hams are asked to help find
transmitters causing interference to local government agency
frequencies, or find the source of TVI. Foxhunting is a way to practice
and polish those skills in a fun activity by tracking down a fellow ham
keying his transmitter at known intervals. Rules for foxhunts vary from
group to group - these are the ones used
by the Illinois Chapter of MARC. |

foxhunt schedule |
There are currently no foxhunts scheduled. If interested contact Perry
Reh, N9MUC.
Come on out and see what this is all about, and the
different techniques used to fox hunt such as signal strength, phase
shift, and sometimes even doppler. Hunt trials, tribulation, and
excuses are discussed after the hunt at a local eatery. Join the Fun!

Some hunters are using GPS and APRS DF
Bearing plots to assist
in navigation and zeroing in on the fox's den. Here is the route
taken by Marc, WB9MAI on the August 2001 hunt to find Bill Thompson,
N9BT
hidden just off of Rt 14 in Arlington Heights.
Skip Allison, K9SA, delivered a great
presentation about APRS at the October, 2004 MARC meeting. You can download his PowerPoint slides here.
