What do you get if you combine handling radio equipment, running (or walking) in the beautiful Swedish nature, and solving a shortest-route problem? It is radio orienteering and in Gothenburg, the local name is Göteborgs Rävjägare (GRJ). All you have is a radio receiver, a map and a compass. Your task is to find radio transmitters hidden in the forest. See https://en.m.wikipedia.org/wiki/Radio_orienteering and https://pejla.se/ for further information.
