Voice of Victory describes the design and construction of Hallicrafters Radio transmitters and receivers and explains how these radios aided our soldiers and allies in World War II. This was a very heavy (and expensive) radio and the first part of the film explores the extensive planning and testing by amateur HAM radio operators that it took to introduce the device to the war front. The second part of the film focuses on the construction and components of the radios. It also documents the assembly of the devices step by step. Anyone who owns a Hallicrafters HT-4 or the modified military version, the BC-610, will find valuable footage of the inner workings of these devices. But the film is also an engaging historical document for viewers with an interest in the history of technology and World War II.
