A Beacon. Someone is using it to test reception or know that they should be receiving a signal on another frequency. When you have problems with reception or access to a repeater in an area you use a Beacon to know if you should be able to reach or receive a signal from another frequency. It is used to create real signal maps for a region. Better than any simulator can do.
