![]() ![]() In the days of the telegraph a message could be sent using a single wire ( and earth return), and for radio communications it could be implemented by turning the transmitted signal or carrier on and off. In this way it is possible to send a message in Morse code by simply turning a signal on and off in the correct manner to represent the dots and dashes. The Morse code is a code that uses a series of dots and dashes to represent the different letters of the alphabet, numbers and procedural notations. It is still used commercially in a number of areas, but it is not widely used. ![]() Despite this Morse code can still be heard when listening on the HF radio bands, and in fact it is still in widespread use in amateur radio or ham radio circles. Nowadays with the development of new technologies, the Morse code has been superseded in terms of technology in many areas of radio communications. Later with the invention of wireless or radio communications, the simplicity of the Morse code lent itself to the transmissions of the day, and it soon gained a new applications becoming a mainstay for radio communications for many years. It was simple to use and flexible, and it soon became a World-Wide standard, allowing communications around the globe. This system became the first widespread method of sending messages over great distances. Initially the Morse code was used for sending messages over a telegraph system and as a result it became known as the Morse telegraph. The Morse code was developed by Samuel Morse and his associates in the middle of the nineteenth Century and has been in widespread use ever since. In these ways, the Morse code is still very much alive and widely used, even after more than 150 years since it was first used. In addition to this, many services that use radio communications still train their users in Morse code in case it is needed for last ditch radio communications, and many radio beacons and similar items may use Morse code to identify themselves. ![]() Today the usage of Morse code is much less than it used to be, but the bottom end of many ham radio bands is still packed with many radio hams communicating using the Morse code. It was widely used for more than a century and provided its value in a variety of areas from land line telegraph systems through to radio communications. The Morse code is a long established form of communication.
