Radio Room

BRIDGE DECK | AMIDSHIPS

00:00 / 00:55

The radio room on a Liberty ship could often be its only link to the outside world.  For security reasons,  ships typically maintained radio silence, but there was still a large amount of radio traffic for the radio operator to monitor. Radio signals were sent in Morse Code, unlike the voice communications that predominate today. 


Merchant ships often carried only a single radio officer, although they could sometimes be assisted by communications personnel from the Naval Armed Guard.  If the ship needed to be abandoned it was equipped with a portable hand-cranked radio, and the radio officer was responsible for transporting this radio to a lifeboat and continuing to send out distress calls.


The O’Brien’s vacuum tube radio equipment is still functional and continues to operate as a commercial radio station under its original wartime call letters, KXCH.
