Walkie-talkie (from walk 'to walk' and to talk 'to speak') or handheld radio (usually abbreviated HFuG) is a radio that has a mains-independent power supply and is designed so that it can be transported and operated by one person. In amateur radio and professional radio services, such as the authorities and organizations with security tasks, it complements the station radios, which are used as vehicle radio stations (see: mobile radio), land radio stations and relay radio stations. In addition, almost all radios in the field of so-called "Everyman radio" - with the exception of CB radio - are usually also designed as handheld radios for licensing reasons.
Many different handheld radios are used in the amateur radio service. Handheld radios can operate mostly on the 2-m and/or 70-cm bands, and more rarely on the 23-cm, 6-m or 10-m bands. Usually, the radios have only (narrowband) frequency modulation for transmitting (10-meter radios often also have single-sideband modulation.) Amplitude modulation and wideband frequency modulation (broadcast reception) are often also available for receiving. Common handheld radios are standard for relay radio use. Operation is also possible via Echolink, provided a DTMF transceiver is fitted. There are also radios available which are additionally equipped with a module for digital signal transmission. As transmission standard C4FM, DMR and D-STAR are common.

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.
