2043B radio

Radio is a Fallout and Fallout 2 item. In the original Fallout, the radio may be used to cause a diversion among the Super Mutants patrolling the outer regions of the Northern Military Base, allowing the player easier access to the base's interior. Attempting to use the radio in other locations elicits a squeal of unintelligible static. It can also be linked with the computer that controls the forcefields within the military base giving you remote control over them.
