Detailed walkthrough
The player character cannot access the top level of the Top of the World unless they repair the signal. One must first travel to the Seneca Rocks Visitor Center and search the bodies there for signal repeater notes and a signal repeater schematic. Look for Darion Jones, in military fatigues.

The materials need to be collected next, including an RCX01-A39 duplexer at the 98 NAR Regional wreckage near the New Appalachian central trainyard and an SMU-97 transponder at the Horizon's Rest plane crash site. The transponder is located on the cliffs, inside the derelict airliner's pilot's cabin, on the wall. The duplexer is in the overturned red NAR wagon just next to the state route at the crash. Watch out for super mutants at Horizon's Rest and robots at the 98 NAR Regional wreckage, including a Sentry Bot.

Once collected, one must combine the two at any tinker's workbench to create a signal booster. With it in hand, head to the National Isolated Radio Array and mount it in the auxiliary dish to the northeast. A group of robots will spawn. These robots are often a group of Mister Gutsies, usually either lieutenants, majors, or colonels. Several of the Gutsies may be legendary enemies as well, meaning that they will explode a few seconds after death. They also have ballistic weaponry that can down a player character in a few hits due to their high firing rate, usually using .44 or .45 rounds. Super mutants will normally be found at the location as well, including one in the structure where the terminal for rerouting the power is located.

After dealing with the robots, reroute the power, listen to Rose's broadcast now that she's able to send it all over Appalachia, and return to Rose at the Top of the World. She will let them up and allow them to "meet" Hank Madigan. This quest is also mandatory to be able to complete Strange Bedfellows as player characters need to be in Rose's good favor before she'll help them meet with Meg and befriend the Raiders.
