Percentage and per-thousand signs: To indicate the % or per thousand, the figure ), the fraction bar and the figures 0 or 00 shall be successively transmitted (i.e.The ITU defines methods in which these may be sent in Morse code: The ITU gives recommendations for a variety of other Morse code characters and occurrences that need to be sent. End of Work, also is given by the ITU as understood. This may result in Morse characters having two slightly different meanings. Some letters and procedural characters are those in common use, but the ITU recommendations have also been used. Invitation for a particular station to transmit (KN) 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. The use of Morse code enables ham radio operators to use their equipment to contact other ham radio stations over great distances. These days the greatest use of the Morse code is for ham radio or amateur radio.

As a result it has been in use for sending telegraph messages as well as radio communications. It refined the first one which had varying character lengths, and the new one was far easier to use. The code which is today called the International Morse code was the second code developed by Samuel Morse. The different Morse code characters have been in use since the 1860s when the Morse code was developed.
