Basic Principles of Using a Walkie Talkie

A walkie talkie, also known as a hand-held radio transceiver, is a two-way, handheld radio transmitter. It operates by picking up signals from a fixed base station and then passing them on to a receiving station. Its development during the Second World War was widely credited to American radio engineers, namely John D. Johnson, Harry W. Coughlin and others at Motorola. It was designed for use by military and civilian personnel to communication tasks such as locating an artillery piece or aerial craft, locating downed airmen, monitoring enemy activity or finding survivors of a crash. Some sources indicate that the first walkie talkie to be used in this manner was the radio sets used by Royal Air Force Pilots in the war.

A walkie talkie can be described as a radio that can receive and transmit on a fixed radio frequency band. This fixed frequency band ranges from thirty megahertz to forty kilobits per second. This means that a typical walkie talkie can transmit over a hundred feet. They work on different modes, for example Mains, PLL or TDMA. Each of these modes is suitable for different applications.

There are various types of walkie talkie for specific purposes. They can be used for general emergencies such as police communications or search-and-rescue operations; they can also be used by fire departments to communicate with their firefighters or EMTs on the scene of an accident. Meanwhile, they are widely used by military and public safety departments for communication tasks during exercises and disaster drills.

Public safety agencies have been using walkie-talkies for years, which is one reason why they are becoming more popular among the general public. In fact, the Federal Aviation Administration (FAA) has even banned the use of two-way radios and their related devices in certain areas such as New York City and Chicago because of security concerns. The reason for this ban is that officials believe these devices can be used to interfere with aircraft surveillance.

In order to minimize interference with other radio devices, it is important that the frequency band used by the walkie talkie is the same as the one used by the speaker and microphone. It should not be too far away but close enough to allow the user to make out a name, address, number or other basic information. In fact, the closer the distance, the better. The closer the two elements are, the less likely it is that one will be able to transmit a message.

One thing that many users forget to think about when using walkie talkies is that they will inevitably be subjected to some level of background noise. Since the transmission is through waves, this can come from other sources, including nearby electronic equipment and even people walking by. If the background noise is too high, the person using the walkie talkie may not be able to make out either the name or address being transmitted, much less receive it. In order to combat this problem, it is often a good idea to purchase a small, lightweight, waterproof headset that is capable of transmitting and picking up sounds at a much lower volume.
