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. the signal goes on to subtly offer an incentive: the person who would rescue them would get whatever they wanted from them(see below).

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.
