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 alerts for minutemen related problems and sometimes give quests for the player to complete.

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. There is currently no known fix for this issue, the only solution is to simply never return to the castle after your initial setup of the settlement, even if castle is under attack, so long as you never enter the area, the minuteman will continue to play radio freedom, and your artillery will continue to function.
