    Apollo 13 Movie - Receiver

    I just watched Apollo 13 and noticed that in the scene where Jim Lovell's wife is in her bedroom she is listening to NASA communications on what appears to be a "NASA" receiver of some sort. I'm just wondering. Was this a legitimate device or a movie prop to bump up the drama? If it IS real...
