Morse code abbreviations Morse code are formed. From 1845 until well into the second half of the 20th century, commercial telegraphic code books were used to shorten telegrams, e.g. "Pascoela = Natives have plundered everything from the wreck". The following Table of Morse code abbreviations and further references to Brevity codes such as the Q code, Z code and R-S-T system serve to facilitate fast and efficient Morse code communications. To make Morse code communications faster and more efficient, there are many internationally agreed patterns or conventions of communication which include: extensive use of abbreviations, use of brevity codes such as the RST
Morse code for non-Latin alphabets Morse code for non-Latin alphabets This is a summary of the use of Morse code to represent alphabets other than Latin. The Greek Morse code alphabet is very similar to the Latin alphabet. It uses one extra letter for Greek letter "Χ" and does not use the codes for Latin letters "J", "U" and "V". The "tonos" is not transmitted in Morse code; the receiver can simply infer which vowels require one. The "Greek diphthongs" presented in the bottom three rows of the table are specified in old Greek Morse-code tables but they are never used in actual communication, the
