Detailed walkthrough

 * To start this quest, you will have to leave the bunker and go back to Elder McNamara. After you complete the quest Still in the Dark, Elder McNamara will ask you once again for your help. Accepting his request will activate.
 * Elder McNamara will give you a Remote Signal Transponder. He will ask that you head to Black Mountain and place the transponder in the broadcast building at the summit. Black Mountain is located near Hidden Valley to the north
 * After you pass the crater you will find a gate, open the gate and a friendly supermutant name Neil will stop you and ask you what you are doing there and warn you of the danger ahead
 * If you pass a Speech check (50), he will aid you in your quest. It is recommended that you have Neil help you since the supermutants are formidable opponents.
 * If you don't have the necessary skill, you must make your way up Black Mountain without him. Neil will be located to the Southwest in a shack.
 * Once you've cleared your way up the mountain, there will be a village with a crater in the center. There are 3-4 more Supermutants here. Neil is behind the Dome structure. The dome has two trunks with a considerable amount of caps in them(Leveled ?).
 * Talk to Neil again and he will create a distraction for you to head up to the Broadcasting Station. There will be a Nightkin Sniper and several leveled Nightkin outside the buildings. The storage area has a treasure hunt inside. Take the note on the dummy, which asks you to find: 1 Missile Launcher, 3 Missiles, 3 C-4 Plastic Explosives, 5 Frag Grenades and 1 Super Stimpack.
 * Head to the radio center, enter, and exit through the rear. Grab the key below the stairs, near some rocks, and head up the stairs.
 * Tabitha will be inside the second floor room (unless you have completed Crazy, Crazy, Crazy). There are 2 ways to deal with her:
 * Reactivate Rhonda, a broken Mister Handy, in the storage room (Science 60 required).
 * Kill her
 * Attach the Remote Signal Transponder to a console in the upper level of the radio center.
 * Report back to Elder McNamara, he says they have been receiving telemetry from the transponder. He will reward the title Brotherhood of Steel Paladin, T-45d Power Armor a lousy reward for a quest as it is in very poor condition and can cost an overall 10000 caps to repair, and full access to the armory.

Bug

 * (pc) Trying to validate the quest when Elder McNamara is at the entrance will stuck your character. You need to wait Elder McNamara to go back to his office room and sit. (ps: feel free to correct my english)
