Semper Fi. Aim High. This We’ll Defend. To all the men and women of the U.S. Armed Forces who have served in any war and given their lives, Motorola remembers. For more than 80 years, we’ve been there too — fighting right beside you. Our Handie-Talkie SCR536 portable two-way radio, developed in 1940 by Galvin Manufacturing Corp. (later Motorola) engineers, was a World War II icon. In 1943, we designed the world’s first FM portable two-way radio, the SCR300 backpack model, for the U.S. Army Signal Corps. Weighing 35 pounds (15.9 kg), this “walkie-talkie” radio had a range of 10 to 20 miles (16-32 km). Yes, Motorola remembers. And we salute you. Learn more about Motorola over the years.
