Simplify Your Life With Two-way Radios

Gone are the days of Samuel F. B. Morse wherein telegraphic information is expressed through dots and dashes or “dits” and “dahs.” In this age, a two-way radio is more usable unlike those of Morse's. A two-way radio can both transmit and receive, unlike a broadcast receiver, which only receives content one-way.

As technology expands, communication always changes and became up-to-date. We can apply it to two-way radios because of its features like the push-to-talk button, which is often present to activate the transmitter. There are also radios that are available in mobile and stationary base configurations like the hand-held portable two-way radio often called as “walkie-talkies” or “handie-talkies.” And in the year 2000, the two-way radio headset was released. Before two-radios began, there are communication devices that help the crew of the ship or air pilots on navigating the seas and skies. As early as 1907, two-way telegraphy traffic across the Atlantic Ocean was commercially available. Senior Constable Frederick William Downie of the Victorian Police developed the first truly mobile two-way radio in Australia in 1923. The Victoria Police were the first in the world to use wireless communication in cars, putting an end to the inefficient status reports via public telephone boxes which had been used until that time. As radio equipment became more powerful, compact, and easier to use, smaller vehicles had two-way radio communication equipment installed. Installation of radio equipment in aircraft allowed scouts to report back observations in real-time, not requiring the pilot to drop messages to troops on the ground below or to land and make a personal report.

During World War II hand-held radio transceivers were extensively used by air and ground troops. Early two-way schemes allowed only one station to transmit at a time while others listened, since all signals were on the same radio frequency, which was called ""simplex"" mode. By using receivers and transmitters tuned to different frequencies, and solving the problems introduced by operation of a transmitter immediately next to a transmitter, simultaneous transmission and reception was possible at each end of a radio link, in so-called ""full duplex"" mode. When voice transmission became possible, dedicated operators were no longer required and two-way use became more common. Today's two-way mobile radio equipment is nearly as simple to use as a household telephone, from the point of view of operating personnel, thereby making two-way radio communications a useful tool in a wide range of personal, commercial and military roles.

An example of a two-way radio that both transmits and receives at the same time is the cellular phone or mobile phone like those of Motorola, which started as producers of car radios and later on, the two-way radios. There are many types and configurations of two-way radios and these are the conventional or trunked, simplex or duplex, push-to-talk, analog or digital, data over two-way radio, which is classified into analog or digital, and engineered or not engineered.

Motorcycle communications is necessary especially in the military and navy officials. It used in reporting the actions in the area. It is indeed definite to have a two-radio at this age because it can simplify and ease communication through love-ones and also for security. Its broad uses and wide coverage will surely make tasks and talks understandable and noteworthy.
