Transmitter hunting is an activity wherein participants use radio direction finding techniques to locate one or more radio transmitters hidden within a designated search area. This activity is most popular among amateur radio enthusiasts, and one organized sport variation is known as Amateur Radio Direction Finding. Other terms used to describe the activity include Radio-Orienteering, T-hunting, Fox Hunting, Bunny Hunting, and Bunny Chasing.
Ok..It's me 50+ years ago... this is an antenna which we put in the back windows of a 53 Chevy... we turned it manually to determine which direction to drive!
We had a ten element yago on the side of the car
Ed and Paul could not figure out why the older guys hung around us?
We now know! Duh!!
The older guys who used to ignore us suddenly became our best buddies, wonder why???
Mobile transmitter hunts refer to organized events where participants travel exclusively or primarily in motor vehicles. Most mobile transmiiter hunts use VHF transmitters and receivers. Some participants use radio direction finding equipment and antennas mounted on a vehicle. Others use antennas that are temporarily deployed in an open window or an opening in the vehicle roof, and that can be easily rotated by hand while the vehicle is in motion.
Other participants employ handheld antennas and radios that can only be used when the vehicle is stationary. Some mobile transmitter hunts require participants to leave their vehicles and proceed on foot to reach the actual location of the radio transmitter.
The winner of a mobile transmitter hunt can be either the first vehicle to arrive at the hidden transmitter, or the vehicle that travels the shortest overall distance to locate the hidden transmitter. Some hunts also feature a separate "mail-in" competition, in which teams in fixed locations work together to locate hidden transmitters, then secretly give the coordinates to the organizers without actually traveling to the site.
The team which provides the closest coordinates wins, thus a team which believes that the transmitter is in the northwest parking lot at 2nd and Elm (if it actually is there) will beat a team which says that the location is 2nd and Elm.
This type of hunt enables participation by contestants who are unable to travel, such as shut-ins, school groups, etc., and requires a greater level of skill and coordination. Mobile transmitter hunts are more popular in North America than other parts of the world.
