Radio Freedom

Radio Freedom is a radio signal in The Commonwealth in Fallout 4.

Radio Freedom is a radio station based from The Castle settlement after reclaiming it for the Minutemen. The radio will broadcast the same music as the Classical Radio station, as well as alerts for Minutemen related problems and sometimes give quests for the player to complete.

Bugs
There is a glitch where if The Castle is attacked, or an alarm is sounded within it's boundaries the Minuteman who plays radio freedom will stand up to fight, and never return to his post, repeatedly claiming that "You've got to restore power before I can continue broadcasting!". Not only does this permanently break radio freedom, it also makes your artillery unusable. Refer to the Radio Freedom Talk Page for a console command workaround. No known fix for Xbox or PS4 yet. Bethesda knows of this bug and has it classified under major bugs so it will likely get fixed for console in the next patch release.

For those who own the PC version a patch file can be found at http://www.nexusmods.com/fallout4/mods/5169/? Once downloaded follow the "Read me" instructions. After you enter the console commands attempt to assign any settler and the original broadcaster will return to his chair.
