Galaxy News Radio (quest)

Galaxy News Radio is a Fallout 3 quest connected with the Galaxy News Radio station. It is also an Xbox 360 achievement.

You must find a radio antenna in the Museum of Technology and place it at the top of the Washington Monument.

While normally you must complete this quest before you can proceed with the main quest, there are two ways to skip it. You can either use the speech skill on Three Dog, at which point he will give you a clue to your father's whereabouts without requiring you to do the quest first, or you can simply travel to Rivet City unprompted and meet with Doctor Li directly. You can still choose to do the Galaxy News Radio quest later by talking to Three Dog. Also, talking to Doctor Li and then completing the quest and talking to Three Dog leads to him giving you the key to a weapon cache.
