Although two-way telegraphy and 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.Well Today,let’s learn something about the history of Walkie Talkies !
Walkie talkies weren’t very popular until the war broke out in 1939. and they suddenly became valuable military technology. In this period, the walkie talkie weighed around five pounds, was about seventeen inches in height, and for the most part it was made entirely of metal.
How Was the Walkie talkie Invented
It is said that 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. but it wasn’t called a walkie talkie at the time. It was simply a two-way field radio. They were also called wireless sets, known as “pack sets”. Journalists who were reporting on this new invention during the war made up the term “walkie talkie.
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 signalling system for his employer CM&S, which he called ‘packset,’ and later on became known as 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.
Continued development of walkie talkie
Nowadays ,Walkie talkies are widely used in any setting where portable radio communications are necessary. including business, public safety, military, outdoor recreation.and the like, and devices are available at numerous price points from inexpensive analog units sold as toys up to ruggedized (i.e. waterproof or intrinsically safe) analog and digital units for use on boats or in heavy industry.
Most countries allow the sale of walkie-talkies for, at least, business, marine communications, and some limited personal uses. such as CB radio, as well as for amateur radio designs. Walkie talkies, thanks to increasing use of miniaturized electronics. can be made very small, with some personal two-way UHF radio models being smaller than a deck of cards (though VHF and HF units can be substantially larger due to the need for larger antennas and battery packs).
In addition, as costs come down. it is possible to add advanced squelch capabilities such as CTCSS (analog squelch) and DCS (digital squelch) (often marketed as “privacy codes”) to inexpensive radios. as well as voice scrambling and trunking capabilities. Some units (especially amateur HTs) also include DTMF keypads for remote operation of various devices such as repeaters. Some models include VOX capability for hands-free operation. as well as the ability to attach external microphones and speakers.
Consumer and commercial equipment differ in a number of ways. commercial gear is generally ruggedized, with metal cases, and often has only a few specific frequencies programmed into it (often, though not always, with a computer or other outside programming device. older units can simply swap crystals), since a given business or public safety agent must often abide by a specific frequency allocation. Consumer gear, on the other hand, is generally made to be small, lightweight, and capable of accessing any channel within the specified band, not just a subset of assigned channels.
Through a span of about eighty years, the walkie-talkie has developed alongside the latest of technologies. As technology has developed, so has the walkie-talkie, and so it will continue to in the years to come. Who knows what the future holds for the walkie-talkie!
