Distress pulser

The distress pulser is a junk item in Fallout 4.

Characteristics
The distress pulser is a device used by the Brotherhood of Steel to mark specific locations, or in the event of an emergency where a soldier or squad may be downed and in need of assistance. When active, it emits a series of blips to any device capable of picking up radio frequencies, which become clearer as the receiver travels closer to the source.

Locations

 * One is located in the National Guard training yard, near the corpse of Tara Astlin.
 * South of Med-Tek Research, in a destroyed building near the corpse of Varham.
 * In the Revere satellite array, in a small shack built on one of the southern satellite dishes.

Bugs
There is a bug where if a distress pulser is dropped on the ground in a settlement and then scrapped using the settlement building screen it will permanently emit a distress signal.
