Anyone associated with communications has heard of the Morse Code. The Morse Code was in widespread use for many years. Initially it was used in telegraph systems, but as radio or wireless began to be used, the Morse Code was adopted for use in this medium as well. Here it provided a very efficient and convenient form of modulating a radio carrier to enable data to be sent. Although far more effective forms of communication are available today, the Morse Code was used for around 150 years and this time it carried huge amounts of traffic and conveyed many important messages.

Morse code history With new and more sophisticated forms of communication now available, the use of the Morse code is has declined considerably in recent years. Many years ago the use of radio began the decline of landline Morse systems. This was compounded by the introduction of the teleprinter that used a keyboard to enter messages, and provided a printed copy at the far end. In Britain the Post Office discontinued the use of landline Morse code in 1932, although its use continued until the 1960s in both the USA and Australia. Whilst the use of the Morse code is in decline it is still widely used in some areas. There are some telegraph enthusiasts who set up historical displays and communicate using original keys and sounders. They use the public telephone system with dial up units and modems to enable them to carry the Morse signals over the public telephone network. The main area in which Morse is used today is for radio transmissions. While the requirement for ships at sea to be able to send Morse code distress signals ended on 31st January 1999, many other still use Morse. Some ships still use it as a cheaper option than the satellite communications systems that are in general use now. Also some armed forces still use it as a last ditch form of communications.
