History of the Walkie Talkie A walkie-talkie is a hand-held portable, bi-directional radio transceiver. The first walkie-talkies were developed for military use. Major characteristics include a half-duplex channel (only one radio transmits at a time, though any number can listen) and a push-to-talk switch that starts transmission. The typical physical format looks somewhat like a telephone handset, possibly slightly larger but still a single unit, with an antenna sticking out of the top. Where a phone's earpiece is only loud enough to be heard by the user, a walkie-talkie's built-in speaker can be heard by the user and those in his immediate vicinity. The first radio receiver/transmitter to be nick-named "Walkie-Talkie" was the backpacked Motorola SCR-300, created by an engineering team in 1940 at the Galvin Manufacturing Company (fore-runner of Motorola). The team consisted of Dan Noble, who conceived of the design using FM technology, Henryk Magnuski who was the principal RF engineer, Marion Bond, Lloyd Morris, and Bill Vogel. Motorola also produced the hand-held AM SCR-536 radio during the war, and it was called the "Handie-Talkie" (HT). Donald L. Hings also worked on the early technology behind the walkie-talkie between 1934 and 1941, and is sometimes said to actually have invented it. A Hand-held transceivers became valuable communication tools for police, emergency services, and industrial and commercial users, using frequencies assigned for these services. Walkie-talkies are also popular with some amateur radio operators, operating with an amateur radio license in several different frequency bands. Since even a powerful commercial walkie-talkie is limited to a few watts of power output and a small antenna (the physical size of the package limits both battery capacity and antenna size), hand-held communication range is typically quite short, with a typical range not exceeding the line-of-sight distance to the horizon in open areas, and much less in built-up areas, within buildings, or underground. Many radio services permit the use of a repeater which is located at some high point within the desired coverage area. The repeater listens on one frequency and retransmits on another, so that reliable hand-held to hand-held unit range can be extended to a few score miles (kilometers) or further, using repeaters linked together. Low-power versions, exempt from licence requirements, are also popular children's toys. Prior to the change of CB radio from licensed to un-licensed status, the typical toy walkie-talkie available in retail stores in North America was limited to 100 milliwatts of power on transmit and the 27 MHz citizens' band channels using AM amplitude modulation only. Later toy walkie-talkies operated in the 49 MHz band, some with FM (frequency modulation), shared with cordless phones and baby monitors. The lowest cost devices are very crude electronically, may employ superregenerative receivers, and may lack even a volume control, but they may have elaborate packaging. Unlike more costly units,low-cost toy walkie-talkies may not have separate microphones and speakers; the receiver's speaker typically doubles as a microphone while in transmit mode. The personal walkie-talkie has now become popular again with the new U.S. Family Radio Service and similar unlicensed services in other countries. While FRS walkie-talkies are also sometimes used as toys because mass-production makes them low cost, they have proper superheterodyne receivers and are a useful communication tool for both business and personal use. Operation in the Family Radio Service is restricted to walkie talkies limited to 500 milliwatts of effective RF power. Some FRS models also include the surrounding GMRS channels, which require a license. Trivia Handie Talkie refers to Mototorla portable products only. According to the US Patent and Trademark Office, Handie Talkie became a trademark of Motorola, Inc. on May 22, 1951. The application was filed June 24, 1948 and the trademark registration number is 71560123. The abbreviation HT is commonly used to refer to portable handheld ham radios (from any manufacturer) in the UHF and VHF ranges. A walkie-talkie is called "talkie-walkie" in French.

Answer in Canada by Donald Hings in 1937
Answer Hi First walkie-talkies were used by radio enthusiasms shortly after Second World War. They were modifying available military equipment, to use for comm…unication. After that, lorry and truck drivers started using CB radio, mobile units for communication.
Al Gross in 1938 and Donald L. Hings invented the second waly talky in 1942.
so the army could talk to each other when someone was behind enemy lines
A walkie-talkie (more formally known as a handheld transceiver) is a hand-held portable, two-way radio transceiver. The first walkie-talkies were developed for militar…y use during World War II, and spread to public safety and eventually commercial and jobsite work after the war. Major characteristics include a half-duplex channel (only one radio transmits at a time, though any number can listen) and a push-to-talk switch that starts transmission. Typical walkie-talkies resemble a telephone handset, possibly slightly larger but still a single unit, with an antenna sticking out of the top. Where a phone's earpiece is only loud enough to be heard by the user, a walkie-talkie's built-in speaker can be heard by the user and those in his immediate vicinity. Hand-held transceivers may be used to communicate between each other, or to vehicle-mounted or base stations.

Motorola invented the walkie-talkie in the 1930s for War communication.
They were originally invented by Mr. Al Gross. He patented them in 1938. Mr. Gross became interested in wireless communication when he was 12 years old and was shown a s…hip's radio during a boat tour. He was still working and giving presentations to school children, one of his favorite things, when he was over 70 years old. Mr. Gross also invented the pager, the CB radio, and came up with the idea behind cellular communications (cell phones). Some sources also give credit for the walkie-talkie to Mr. Donald Hings. He had a walkie-talkie that was introduced in 1942. Mr. Hings may have come up with the name "walkie-talkies." He was asked what people could do with the radio, and he said, "walk and talk." He died on December 21, 2000. http://library.thinkquest.org/04oct/00451/walkietalkie.htm
