Signal Sierra Romeo

Broadcast tower KT8 is located directly north of Little Lamplight and northeast of Vault 87. Upon activation of the tower, one will receive the Radio Signal Sierra Romeo in Morse code. Down a cliff northeast of the tower is a drainage chamber which can be easily seen from the local map. This is one of nine drainage chambers broadcasting a Morse code signal.

Drainage chamber
In the chamber there are two pre-War books and a motorcycle handbrake and motorcycle gas tank, Pork n' Beans and Sugar Bombs. There are two terminals, one broken and the other with some mixed script with the error of an "invalid decry.key" when activated. On the third desk lies the encryption key. It can be used on the encrypted terminal to open the trap door on the floor to the right.

Downstairs one will find the ham radio signal source and two dead Chinese remnant spies. In this chamber, there's also a mini nuke, a Chinese Army: Special Ops Training Manual, a Chinese commando hat, two bottles of purified water under the desk, and various other objects.

Morse code
The station transmits:

The message is as follows: "Calling anyone this is Sierra Romeo over," with "over" meaning, "I am awaiting a reply."
