Boston City Works Beacon

Boston City Works Beacon is a radio beacon in Fallout 4. It is broadcast from an unmarked location close to Relay tower 1DL-109, approximately halfway to Forest Grove marsh.

Location
The radio broadcast is found when extending the Relay tower 1DL-109. The signal origin is 89 meters away and can be found by heading west, towards Forest Grove marsh. The location is a waterway lock, and is broadcast from inside the Operations building. Once inside, there is a hatch hidden behind some cardboard boxes that allows access to a small sublevel.

Bugs
This signal and the nearby distress signal and Garbled radio beacon may not turn off when their original ham radios are turned off by the player. Leaving and re-entering the area may resolve this.
