Welcome to the San Diego Transmitter Hunters
We are all about ham radio with a focus on Transmitter Hunting. Transmitter hunting is a service that we practice two times a month so we can participate in emergency situation such as a downed aircraft that has a radio beacon that is transmitting. But don't let this practical reasoning be addressed as a boring application. Transmitter hunting has become a game, a fun game in reality to develop Transmitter hunting skill. Transmitter hunting can be as simple as using a hand held 2 meter radio as a receiver to receive the signals of the hidden transmitter while using ones body as an attenuator to determine the direction of the hidden transmitter or using sophisticated equipment that plots the direction on a computer screen while you drive following the direction of the hidden transmitter. The art of Transmitter hunting has become a game of luck and skill to see who is going to find the hidden transmitter first knowing that if they do find it first it is their turn to hide the transmitter on the next hunt with intension of fooling the hunters. Transmitter hunting, Fox hunting or Radio Direction Finding (RDF) is used to locate the exact location of a radio transmitter broadcasting a signal. A transmitter is hidden in a boundary by a transmitter hunter who had won the previous hunt. Mobile transmitter hunting is organized events where participants travel exclusively or primarily in motor vehicles. Most mobile transmitter hunting hunters use VHF transmitters and receivers. Some participants use radio direction finding equipment and antennas mounted on a vehicle, whereas others use antennas that are temporarily deployed in an open window or an opening in the vehicle roof 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 hunting 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 hunting event 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. Mobile transmitter hunting events are more popular in North America than other parts of the world.
On Foot Hunts
On foot Foxhunting is a map and compass exercise as well as a test of direction-finding skill. Successful hunters pay careful attention to their own location and the bearings to all foxes at all times, plotting them on detailed orienteering maps provided by the organizers. They know that if they miss a fox bearing, they must wait four minutes to hear that fox again. They also eye their watches, since exceeding the time limit (usually two to three hours) means disqualification. In other words, it is better to return under the limit with only one fox found than to find all five but take one minute over the limit.
All competitors use the same venue and search for the same foxes, but there are eleven age/gender categories (per rules revision in September 2009). Only one category (M21) is always required to find all five. Others usually need to find two to four foxes; the designated ones to find are different for each category. Foxes may be found in any order.
