A walkie-talkie is a hand held two way radio receiver/transmitter or transceiver. It was developed in the Second World War.

Radio engineer Alfred J. Gross worked on the early technology behind the walkie-talkie between 1934 and 1941. During the war it was developed by Donald L. Hings and engineering teams at Motorola led by Henryk Magnuski.[1][2]

Typical walkie-talkies today are phone sized and have a push-to-talk button. Walkie-talkies are used for various reasons, in the military, for amateur radio, and for personal use.

History[change | change source]

The first walkie-talkie was so large it had to be carried in a backpack, and was called Motorola SCR-300. Motorola also made other Walkie-talkies during World War Two.[3] During World War Two The first hand-held Walkie-talkies were also developed by Motorola during WWII.[4]

Development[change | change source]

The idea of walkie-talkies did not get much interest until the war started in 1939. After a few years, the Motorola team had improved them so that the army could use them. There were also vehicle and tank versions.[1] The British, Germans, and Americans all had their own versions.

Motorola also produced the hand-held AM SCR-536 radio during World War II, and it was called the "handie-talkie" (HT).[4] The terms are often confused today, but the original walkie talkie referred to the back mounted model, while the handie-talkie was the device which could be held entirely in the hand (but had vastly reduced range).

Uses[change | change source]

Walkie-talkies are widely used in many settings, including business, police force, military, and recreation.
