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. |

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.
