Morse Code Chart / Table
- a Morse code chart or table giving the Morse signals and their corresponding letters and characters which today is widely used in ham radio or amateur radio applications.
This summary of Morse code, keys and keyers is split into several pages: What is the Morse code

The different Morse code characters have been in use since the 1860s when the Morse code was developed. The code which is today called the International Morse code was the second code developed by Samuel Morse. It refined the first one which had varying character lengths, and the new one was far easier to use. As a result it has been in use for sending telegraph messages as well as radio communications.
These days the greatest use of the Morse code is for ham radio or amateur radio. The use of Morse code enables ham radio operators to use their equipment to contact other ham radio stations over great distances. The advantages arising from the simplicity of the use of Morse code, allow many ham radio enthusiasts to construct their own equipment as well as allowing contacts to be made when signal strengths are low and interference levels are high.

Some letters and procedural characters are those in common use, but the ITU recommendations have also been used. This may result in Morse characters having two slightly different meanings. VA, i.e. End of Work, also is given by the ITU as understood.
Additional Morse code characters
The ITU gives recommendations for a variety of other Morse code characters and occurrences that need to be sent. The ITU defines methods in which these may be sent in Morse code:
Length of Morse code characters
In order that the Morse code characters are easy to read, it is necessary to ensure that they are the correct length. Too long or too short, and the Morse code messages can be very difficult to read as the rhythm of the different characters is destroyed. Part of the International Morse code "standard" is an agreed definition of the various lengths of dots, dashes and spaces.
By keeping to these lengths the Morse code characters are much easier to read.
The Morse code is still widely used for amateur radio or ham radio applications. It enables ham radio contacts to be made all over the world with ease, especially when using low powers or more modest antennas. While the Morse code is not generally widely used, it still has applications for ham radio, and the above Morse code chart or Morse code table is useful to identify the main symbols used.
