Greenbriar radio signal

The Greenbriar radio signal is a radio station in the Commonwealth in 2287. It can be picked up after extending the satellites at radio tower 3SM-U81. It is a distress signal from a group of survivors hiding in an abandoned bunker, surrounded by unidentified creatures.

Characteristics
The bunker is straight east of radio tower 3SM-U81 on the western bank of the river. The hatch down into the bunker is hidden in the bushes behind an iron barrel in a run-down camp site. There are two nearby camp sites. The correct one has a picnic bench and a cooking station, the other one has some dead settlers/traders.

At higher levels a mirelurk queen may spawn near the entrance of the bunker.

Inside are two skeletons, a number of food coolers, a few first aid kits, a wooden crate, a hunting rifle, a suitcase and the Ham radio broadcasting the signal.

Behind the scenes
The Greenbrier Resort in West Virginia was home to the "continuity of government" bunker designated for members of Congress and their families in case of an apocalyptic event. It later appeared in Fallout 76 as the Whitespring Resort.
