Signal Oscar Tango

A radio transmission in the vicinity of Jury Street Metro Station. The large antenna tower near the station entrance can be turned on after unlocking the gate. Once the power is restored, it begins broadcasting morse code.

The signal equipment is in the nearby Drainage Chamber, which is accessed through a nearby manhole cover. There is a protected sleeping chamber under the room with the radio equipment, which can be accessed by a wall switch opposite the radio. Accessing it can cause two garden variety raiders to spawn and attack.

It appears that raiders detected the people who sent the signal. After torturing and killing them, the raiders deactivated the signal tower and took the chamber for their own.

Morse code translation:

CQ CQ CQ DE OT OT OT K

This translates to "calling anyone, this is Oscar Tango, over".
