Distress signal (Relay tower 1DL-109)

Distress signal is a radio station in Fallout 4. It can be picked up after extending the satellites at relay tower 1DL-109.

Location
The origin of the signal is a ham radio inside a train car, southeast of the relay tower. The train is, as mentioned in the broadcast, surrounded by several feral ghouls. The fourth car (blue toppled over train car) from the north has a hatch to an interior on the car's top end, partially hidden behind a bush. Inside this car are the skeletal remains of a woman surrounded by blood, a locked crate and the broadcasting ham radio. Also a small teddy bear without it's owner.

Bugs
This signal and the nearby Boston City Works Beacon and garbled radio beacon do not turn off when their original ham radios are turned off by the player. This has been fixed in the 1.4 patch.
