Signal Oscar Zulu
 Drainage chamber
Relay tower KX-B8-11 is located northeast of the Temple of the Union, and far south of the Republic of Dave. When activated by a switch on a transformer below the tower, it broadcasts a plea for medical assistance for the son of Bob Andersteen. This is one of nine drainage chambers with a ham radio signal. The message repeats:
If anyone can hear this, this is Bob Andersteen.
My family and I have taken refuge in a drainage chamber not to far from a radio relay tower outside of DC.
My boy is very sick and needs medical assistance, please help us if you can! We are listening for your response on 3,950 kHz.
To the southeast and down a hill, at the base of the cliff to your right, you will see a sewer gate. Within are two small chambers. One is a living area with two adult skeletons (male and female) along with food, surgical tubing, a crutch, and other assorted medical supplies. However, despite the message stating that Bob Anderstein has a young boy with him, there is no third child skeleton to be found. It is presumed that the child either out-lived his parents and left the safety of the sewer, or the game designers simply forgot to add a third corpse. In the opposite chamber, there is a burnt out terminal and the ham radio used to broadcast the distress signal, as well as a pre-War book, a D.C. Journal of Internal Medicine, and purified water.
- This is one of two amateur radio transmissions that do not include Morse code; the other is signal Yankee Bravo.
