A walkie-talkie is a hand held device, two way radio receiver/transmitter. 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.

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

Field of application

Handheld radios are not only used on the bike, on fielddays or during walks, but also in the car or at the location of the registered amateur radio station. Amateur radios are rarely also used by BOS radio units on BOS frequencies, although they have no approval for this radio service. Here one takes advantage of the fact that the frequency ranges of modern handheld radios can be extended. Thus, the radios are not only prepared for radio abroad (there are larger amateur bands available), but also for emergency radio.
