Shown here is the Hallicrafters Model RE-1 Sky Courier receiver from 1945. For the G.I. far from home, the radio was as important as mail call in staying connected with home. Early in the war, whatever receiver could be found was pressed into service, but the harsh conditions meant that the military needed a rugged “morale” set, and the RE-1 was the answer.

The set could operate from batteries (90 and 9 volts) or AC power. The method for switching was ingenious. To switch to battery operation, the line cord was inserted into a jack in the back of the radio. The prongs of the cord completed two circuits, and thus served as a DPDT switch, connecting the batteries. The set tuned 550-1600 kHz and 2.8-19 MHz, and contained a built-in antenna.

Above all the set was rugged, and was designed to resist both corrosion and fungus.

The picture and description appeared in the May 1945 issue of Radio News.
