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.

Fantastic finish for the night radio orienteering. Thanks to banlaggare Erik Sandwall and the nice little cabin.

Probably a new record for the number of participants at 9 people. Thanks to Robert for bringing in folks. Perhaps, we should have additional bonus points for bringing a new person to this sport.

It was again a close finish with the map scale at 1:6000 and without the screens. Robert took the championship by 8 seconds. The second place was equally tight between Tilak and Albin, where Albin dived for the fox and Tilak dived for the plug a fraction later. Albin was a gentleman in saying that Tilak has the plug and let him punch the control. The difference in the recorded time between second  and third is 7 seconds.

Perhaps, the night hunts could be improved with the installation of orienteering screen so that the hunters don’t gather together at the same control,  waiting for the next  transmission. Perhaps some discussion points for the avslutningsfest.

It was good to see the old timers Ingvar and Lars R.
