About Radio Orienteering

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.

All are welcome to reach us and try this sport. See About us / Contact us page for more details.

Results of Dag DM, Hisingsparken, 23rd Sept’18

It was a lovely warm day in September to have the DM at Hisingsparken. It was great to see Erik A who showed up well before the time to meet. He as missing from action for many months. Lars R being on schedule had to park some distance away, as parking was full. Without the help of Lars R, setting up this hunt would have been difficult. As he helped out taking the additional equipment. Thanks Lars R!

The tracks are pleasing to run. Going from 2-5-1-3-4 took around 6.9 kms when planting the foxes. There were people everywhere, especially those who were hunting for mushrooms!

Unfortunately or luckily there were at least two people for the DM. Looking at the map, I think Erik took the optimal route, coming in first at 1 hour and 1 minute while Lars took in 1 hour and 37 minutes. It was great to follow the hunter count, as it felt like a football commentary as to where the competitors were and in what order they are taking.

I felt like I should have kept fox 2 and fox 4 at equal distance such that they were equally loud. But then, that would have been easily 7.5+kms. Potentially, taking more than 2 hours if senior competitors took them by walk.

Finally, at the awards ceremony, it was strange to be other end of trophy, handing it out to the winner.

 

Update: Now with Erik Sandwall’s optimum route calculation, it appears that Erik A took the optimal path with 4-3-2-5-1 with bird’s flight distance of 3093 meters while the 2nd shortest route was 2-4-3-5-1 with 3096 meters. For the second shortest route, I guess one would have to swim across slätta damm 🙂
