How Was the Walkie-talkie Invented
Although two-way telegraphy and the two-way radio has been invented years earlier, it was only during the years from 1934 to 1941 when the first hand-held two-way transceiver or the walkie-talkie was first developed.
Two persons and an engineering team were credited for inventing the device, and they are radio engineer Alfred J. Gross, Canadian Donald L. Hings, and Motorola’s engineering team.
The three were credited for the invention of the walkie-talkie because each of them came out with their respective inventions and contributions leading to the full development of the first official walkie-talkie.
Radio engineer and developer of the Joan –Elenor system made the first real attempt to develop the early technology behind the walkie-talkie from 1934 to 1941.
In 1937, Canadian inventor Donald L. Hings also developed a portable signaling system for his employer CM&S, which he called ‘packset,’ and later on became known as a walkie-talkie.
Three years later, an engineering team at the Galvin Manufacturing Company, which would later become Motorola, developed the first radio receiver/transmitter, the backpacked Motorola SCR-300, which they also nicknamed walkie-talkie.
During World War II, similar designs of the walkie-talkie were developed for the military, which also contributed significantly to battle strategies, and even to winning the war.
Subsequently, post-war development of the walkie-talkie spread to public safety and eventually to commercial and the business front.
The old walkie-talkies were only operating in half-duplex mode or within a single radio frequency, which means that transmission is done one at a time between communicating parties through the traditional ‘push-to-talk’ button on the walkie-talkie.
The first hand-held walkie-talkies were also larger than a telephone handset and featured an antenna mounted on top of the unit. As radio equipment become more powerful, compact and easy to use, the subsequent walkie-talkie designs became smaller over time.
These days, modern-day walkie-talkies already appear like mobile phones. Motorola has developed a mobile phone, that also serves as a walkie-talkie, which became a hit among many companies in the world.
