Signal Oscar Tango is 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. Opposite the radio on the chamber's east wall is an electrical switch which opens the sleeping chamber below. Inside are several bodies mutilated by raiders. As you are inside the chamber, two raiders may enter the chamber above you, which means you have to fight your way out.
