Walkie-talkie
hand-held two-way radio communication device
A walkie-talkie, more formally known as a handheld transceiver or handheld radio, is a hand-held, portable, two-way radio transceiver. Its development during the Second World War has been variously credited to Donald Hings, radio engineer Alfred J. Gross, and to Henryk Magnuski and engineering teams at Motorola. First used for infantry, similar designs were created for field artillery and tank units. After the war, walkie-talkies spread to public safety and eventually commercial and jobsite work.
Typical walkie-talkies resemble a telephone handset, with a speaker built into one end and a microphone in the other (in some devices the speaker is also used as the microphone) and an antenna mounted on the top of the unit. They are held up to the face to talk. A walkie-talkie is a half-duplex communication device. Multiple walkie-talkies use a single radio channel, and only one radio on the channel can transmit at a time, although any number can listen. The transceiver is normally in receive mode; when the user wants to talk they must press a "push-to-talk" (PTT) button that turns off the receiver and turns on the transmitter. Some units have additional features such as sending calls, call reception with vibration alarm, keypad locking, and a stopwatch.
“Walkie-talkie” enters the record as hand-held two-way radio communication device. Crown Archives preserves that source wording while asking what Walkie-talkie, hand-held and two-way can confirm, complicate or overturn.
Why this record matters
“Walkie-talkie” is worth following because a concise public description often conceals a longer documentary argument. Here, Walkie-talkie, hand-held and two-way provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q938319. The Library of Congress control number is sh85144899. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
