Broadcast Tower KT8

The  is located north/northeast of Vault 87, south of Shalebridge in the mountains.

There's only a radio antenna and its generator (the latter's switch can be flipped to emit Radio Signal Sierra Romeo). Quite a few bent metal girders on the site suggest a typical mutant outpost.

A couple of super mutants and possibly a centaur can be found wandering the area. If the player visits this area after escaping the Jefferson Memorial through to the Citadel there may be a small scene with 2 Vertibirds: one will be shot down by a missile and the other escapes. The culprit, a Super Mutant with a Missile Launcher, can be seen near the broadcast relay. Not surprisingly, he will shoot you on sight.

Drainage Chamber
Just slightly to the north, below the cliffs the broadcast tower is built upon in the alleyway that cuts between the rocks you will find  "Sewer Entrance to Drainage Chamber". Inside you will find collapsed sewage tunnels and a door. In this room should be random custom-weapon items, and two computer terminals. One is broken, the other requires a decryption key to open the secure hatch in the floor, unveiling the source of Radio Signal Sierra Romeo. The decryption key is on top of the desk in the same room.

In the subchamber, you'll find a ham radio along with the remains of two Chinese Remnant Spies. It's unclear what killed the two spies (unlike other towers where you'll often find clear signs of raider violence), but it is a possibility that they starved to death or died of radiation poisoning, even though there is plenty of food in the computer chamber.

Interestingly enough, if they are resurrected with the console, they have normal ghoul voices instead of Chinese voices.

Notable Loot
There are two Pre-War Books in the room with the computer terminals.

There is a mini nuke, some Purified Water, a Chinese Commando Hat (with matching Chinese Jumpsuits), and a copy of the Chinese Army: Special Ops Training Manual in the sub-level with the two spies.
