History Of The Walkie Talkie

Before the world of mobile phones, we needed another way of instant communication when out and about. The walkie talkie served that purpose, and although they have more limitations than the mobile phone, they are still used extensively. It’s a tried and tested technology and cheap to run. The two way radio with its familiar antenna poking out of the top was first developed for the military. The company that later became Motorola invented the technology in 1940, the first kits were known as the handie talkie and were in use during World War II.

The system was soon taken up by the emergency services, including the police force. Industry also found a use for it, especially for workers involved in locations such as oil fields or construction sites. Frequencies are designated by the authorities and are strictly controlled. The amateur radio operators, or hams as they are known, were keen enthusiasts for the walkie talkie from the beginning. They have to have a license to operate by law. Many people who enjoy outdoor activities such as hiking have found them very useful. They are invaluable if an accident occurs and help is needed quickly.

The range is limited of course and is better in an open space than in built up areas. Underground situations or the interior of buildings will also affect the workable range for communication. The power output is determined by the batteries and the size of the antennae. The design of the walkie talkie has to be a balance between communication range and a size of receiver that is practical for use.

The toy market saw the potential and a number of manufacturers make working, toy versions. Children love to play with these and there is no license necessary because of the low power involved. Parents can have fun and keep tabs on their child.

These radios are as popular as ever, for business and social customers. Ultra high frequency band models are available now, which are more efficient than the citizens band radio so loved by truckers. Today’s walkie talkie doesn’t have to be as big as a brick now and you can buy slim line, lightweight models. They come with accessories such as earphones, belt clip and case cover. You can even get a two way radio watch, just like James Bond! If you’re technically minded, it is possible to make your own set of walkie talkies from two cordless telephones.
