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 Relay Tower you will spot a car on what remains of the road. The drainage pipe is just south, and down the short cliff from the vehicle. Within is a small chamber, a living area with two adult sets of skeletal remains along with assorted supplies, a pre-war book, D.C. Journal of Internal Medicine, and Purified Water. In the opposite chamber, there is a burnt-out terminal and the HAM Radio used to broadcast the distress signal.

On the room opposite to it are 3 skeletons (of the family of 3) and some packaged food, which indicates that you're to late to the rescue.
