About Radio Orienteering

Quick Introduction to the ARDF sport – Radio Orienteering

What do you get if you combine a small hand-held radio equipment, running (or walking) in the beautiful Swedish nature, and solving a shortest-route problem? You get radio orienteering and in Gothenburg, the local name is Göteborgs Rävjägare (GRJ). Note that we do not hunt any fox (räv), it is just a name from the dinosaur era (1950s). We simply look for radio transmitters hidden in the landscape on a given map with the help of a compass and more importantly a radio receiver. The location of the transmitters are not provided on the radio-orienteering map, unlike regular-orienteering maps.

Your task is to find radio transmitters hidden in the forest. Usually there are five transmitters that takes turns transmitting a Morse signal with its identity while the other transmitters remain silent. See https://en.wikipedia.org/wiki/Radio_orienteering and https://pejla.se/ for further information.
