History

The Crosley Corporation of Cincinnati, Ohio manufactured the Signal Corps Radio set SCR-284 that consisted of the BC-654 and associated support equipment.

The BC-654 was introduced in Africa during Operation Torch and was the first radio set used for communications from the beach to the U.S. Fleet to coordinate naval gunfire and beach radio networks. More than 50,000 BC-654s were produced and delivered in support of Operation Overlord, the D-Day invasion of Normandy. Over 150,000 units were eventually produced in total. After the war, many BC-654s were sold as surplus for $15 each. Today, many are restored and operated by vintage amateur radio enthusiasts.
