Signal Oscar Zulu

Located in the North-Eastern area of the Fallout 3 Map, South of the Republic of Dave, the Relay Tower 'KX-B8-11', when activated, will relay a message from Bob Anderstein, a plea for medical assistance for his son, who is sick.

To the South-East of the Tower is the Drainage Pipe Bob mentions. Within is a small chamber, a living area with two adult sets of skeletal remains along with assorted supplies and Purified Water. In the opposite chamber, there is a burnt-out terminal and the HAM Radio used to broadcast the distress signal.

It is uncertain if the son also died along with his parents, or recovered and eventually left, as there are no child remains.
