Foxoring

from Wikipedia, the free encyclopedia
80 m direction finder

Foxoring is a combination of amateur radio arrows (ARDF) and orienteering . The word "foxoring" is made up of fox hunt and o rientee ring .

Circles are drawn on a terrain map (ideally an orienteering map ), in each of which a mini-transmitter can be heard that has to be started. The transmitter does not have to be in the middle of the circle or in the circle itself, but it must be audible in the entire area of ​​the circle.

Small transmitters are used as transmitters, all of which constantly transmit on the same frequency. Their range is generally around 50 to 200 m. The actual range may vary depending on the type of transmitter, the installation location and the time of day. When designing the transmitters, you should therefore ensure that there is overlap. In contrast to a classic direction finding event with five transmitters, there are no specifications for the number of transmitters in Foxoring; sometimes more than 20 transmitters are used. Although foxoring can be carried out on the 80-meter as well as on the 2-meter tape , there are mostly only 80-meter foxoring. The reasons for this are the low prevalence of 2-meter Foxoring transmitters and the fact that with Foxoring it is not the direction finding technique that is in the foreground, but orientation in the terrain.

As with classic amateur radio direction finding, stamping pliers and control cards or electronic timekeeping systems are used to prove that a transmitter has been found .

Foxoring competitions have been part of the ARDF World Championships as well as the IARU Region 1 and Region 2 championships since 2012 . A maximum of ten transmitters are used.
