In this game, players are looking for hidden @boardname@ that emit radio signals.
The hidden @boardname@ are called **beacons**.
### Setting up the radio
## Setting up the radio
We set the radio group to ``1`` to make sure all the players are using the same group.
We also tell the @boardname@ to transmit its serial number (that's a unique number that identifies it)

The beacon simply needs to send a radio message every now and then. To pace it out,
we add some ``|show icon|`` blocks to animate the screen.

## Is the beacon close?
To determine how far or close, we use the signal strength of each radio packet sent by the beacons. The signal
strength ranges from ``-128db`` (weak) to ``-42db`` (very strong).

The hunter screen displays ``SmallDiamond`` on the screen if the beacon is far, ``Diamond`` mildly close and ``Square`` if it is close. Use the ``signal`` values collected in the previous step to determine when to show those letters.
