Relay Tower KX-B8-11

Located on northeast of the Capital Wasteland, this station, after turning her power source on, broadcast Signal Oscar Zulu to the near vicinity.

Underneath the hill is a drain culvert containing some pre-war books, purified water, other sundries, the long dead bodies of the broadcaster, and the ham radio set producing the signal which you can turn off. It's kind of nice in that it has a sleeping bed and no aggro creatures if you happen to be hurt.
