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 dish on the Lunar Lander 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.

If you discover your father's whereabouts from someone other than Three Dog and still complete this quest he will compliment your upstandingness and then give you the key and map market to his personal weapons stash at Hamilton's Hideaway.

Quest
To begin this quest, proceed down the stairs (in the same area as Three Dog) to the back door of the Galaxy News Radio (station) leading to the car tunnels to Dupont Circle.

There is a known bug in the Xbox 360 version of the game where, if you do not exit Galaxy News Radio via the back door as Three Dog instructs, you will be unable to return to the building to complete the quest via the front door (using the intercom will result in the doorman telling you that it's open, when it's not), and the side-door will be locked and require a successful very hard lockpick to open. It is not known if you can backtrack from Dupont Circle to the back door, but dialog from Three Dog when you accept the quest would suggest that you cannot. Picking the very hard side door will result in negative karma, but will allow you entrace to the building to complete this quest.

NOTE: You will meet many hostile Feral Ghouls, Super Mutants, Wild dogs and Raiders in the tunnels, so Fast Travel to Megaton first to stock up on Stimpaks, ammo and weapons. If you have any form of Assault Rifle and Small Guns this quest should be much easier.

Enter the car tunnel door and walk through the tunnels exiting into the outdoors. Enter the Dupont Station, where you will encounter two Super Mutants. Headshots with an Assault Rifle will finish them off, and these will be the last two in the station. Follow the way points (heading south and staying on the Red Metro line always) for a long but easy distance, passing the Central Station, then later arriving at the Museum.

Inside the Museum you need to find the parabol. Some Super Mutants and Super Mutants Brutes are around so you better have some ammo to take care of them with. The Quest item is the antenna/parabol on the Lunar Lander.

Grab the antenna, exit the Museum and head for the Washington Monument. It is also in the Capital Mall area and can be seen from the entrance to the Museum of Technology - it is a giant, needle-like obelisk to the West of your location. There are Brotherhood guards stationed here that will grant you entrance. Take the elevator to the top, and interact with the radio equipment here to install the dish. Finally, return to Three Dog at Galaxy News Radio to finish the quest.
