Distress signal (Brotherhood of Steel)

Distress signal is a radio station in Fallout 4.

The signal is found during the Brotherhood of Steel quests The Lost Patrol and Liberty Reprimed. This signal is emitted from a distress pulser. When listened to it on the Pip-Boy, the broadcast consists of monotonous beeping noises which change tempo depending on the player character's proximity to the pulser itself.

During The Lost Patrol, the player character can pick up these distress pulsers, which takes the distress signal station off the air.
