A walkie-talkie, more formally known as a handheld transceiver, HT, 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 , Henryk Magnuski and engineering teams at Motorola .
Batteries are a notoriously expensive part of building out your toolkit, so getting a free charger and two batteries (3.0 amp-hour and 5.0 amp-hour) certainly sweetens the pot.
The SCR-536 is often considered the first of modern hand-held, self-contained, "handie talkie" transceivers (two-way radios). It was developed in 1940 by a team led by Don Mitchell, chief engineer for Galvin Manufacturing (now Motorola Solutions) and was the first true hand-held unit to see widespread use. [1]
The equipment tag glued to the edge of the front panel was the main (external) way to tell the difference. The original batteries had a 3 V tap (series diode-reduced to 2.4 V) for the PRC-25's tube filament. This remained unchanged so the batteries could operate either radio it was placed in, but the PRC-77 did not use the 3 V tap at all.
Several hand-held Project 25 radios used around the world. Project 25 (P25 or APCO-25) is a suite of standards for interoperable digital two-way radio products. P25 was developed by public safety professionals in North America and has gained acceptance for public safety, security, public service, and commercial applications worldwide. [1]
Donald Lewes Hings, CM MBE (November 6, 1907 – February 25, 2004) was a British-Canadian inventor, born in Leicester, England.In 1937 [1] he created a portable radio signaling system for his employer CM&S, which he called a "packset", but which later became known as the "Walkie-Talkie".
Although a relatively large backpack-carried radio rather than a handheld model, the SCR-300 was described in War Department Technical Manual TM-11-242 as "primarily intended as a walkie-talkie for foot combat troops", and so the term "walkie-talkie" first came into use. [3] The final acceptance tests took place at Fort Knox, Kentucky in Spring ...
