A new adventure of John Bont.

To take part in this exciting game, Scouts need:

  • an amateur radio station capable to communicate with other amateur radio stations, preferably on the HF bands.
  • or a web radio receiver that can be operated by a computer, e.g at
  • A computer connected to the internet or a radio contact with someone that operates such a computer.
  • A printer connected to the computer.
  • An Android smart phone
  • A piece of yellow paper, letter size or A4 size.
  • A similar piece of blank, white paper and a pencil to make notes.
  • Scout map reading skills.
  • Ingenuity and creativity.

Scouts can take part individually, in patrol units or as a group.


  • Work together with a Scout group in another country (to get the starting info for the game)
  • Experience how to make a radio contact or listen to short-wave transmissions
  • Learn the spell alphabet
  • Train basic map reading skills and compass use
  • Learn how to download and install an app on a smartphone
  • Experience information coding and decoding
  • Have fun discovering our world


John Bont & the hunt for the lost treasure


John Bont is the special agent of the Bureau of Information and Valuables (BIV). For this new mission, John has to retrace vital information that has gone missing, information that may lead him to a long-lost treasure. The BIV suspects it is hidden on a non-populated island, somewhere. Luckily, John was able to find a map of the Island.agent

The Bureau has arranged that John is airlifted to this island; he is dropped by parachute at point A (coordinate 25101700).

After his safe landing, John Bont takes his compass: he has to walk 1.4 km in the direction 45 degrees. John quickly walks in a straight line and arrives at point B (plot his position on the map and note the map coordinates).

Here at B he is able to use his short-wave radio. He checks his watch for the correct time, and dials his radio to the agreed frequency. Then he listens for a contact with 9M4S. John fist reports the coordinates of his position at point B to the 9M4S station. If he does this correctly, he receives a code set of 4 letters. John knows that in case he cannot reach 9M4S directly, he can also ask another participating radio station in the network for this information. There is at least one such station on each continent.  It may take a while before he finds someone who has these letters, but he is patient and keeps trying. At last he succeeds and carefully writes down the 4 letters he received. He marks them as group Y.

Quickly John packs up his gear and rushes another 1.6 km in the direction 342 degrees. This is point C (mark this on the map and again note the map coordinates). At C he finds an old smugglers cabin with a PC. And yes, the PC is still working. Would this be the key to the lost information?

John now searches his back-pack. Where did I put my very smart phone? Ah, he finds the connection wire and the phone; brilliant. John carefully connects his phone to the old PC and switches both of them on. Following what he learned in his Scout troop, he now downloads from the Google Play Store an App called “Enigma Simulator”. John knows that it can break any code, as long as he uses the M4 type machine, so as a precaution, he needs that App.

But what about the ring settings. Wooh, how to get those? BIV did not gave him any clue for that. John has to sit down and think. He nervously fiddles around his radio buttons. Would the radio help?

What did his patrol leader used to say? “if you can’t see the answer, you are sitting on it”. John looks around him. Sitting on it? He sits on point C, on top of a hill. Of course, that’s it ! John enters the map coordinates of point C into the Enigma settings. There we go. He reels the four wheels into the starting position, which is always JOTA. John now enters the four letters of group Y that he received. The Enigma machine gives him four new letters. John carefully notes down these new letters and he notes them as group X.


John’s heart beats fast as he types the following address into the PC’s web browser:

http:\\[4 letters of group X][4 letters of group Y].

A mysterious web page appears on the screen. Yes! John pushes the print button but in his enthusiasm forgot to switch the printer on. He puts the special yellow paper in the printer and tries again. Yes, he’s got it !!

John Bont carefully folds the paper and puts it in his pocket. Mission accomplished. He walks outside and finds a shady place under a tree. He opens up his lunch box to find out what BIV has prepared him for lunch..….
