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 abbreviations provided by the prosigns for Morse code, the International Q code, Z code, RST code, the telegraph era Phillips Code and many well known Morse code abbreviations as discussed in this Wikipedia article. Together all of these traditional conventions serve as a somewhat cryptic but commonly understood language (Lingua Franca) within the worldwide community of amateur radio Morse code operators. These codes and protocols efficiently encode many well known statements and questions from many languages into short simple character groups which may be sent manually very quickly. The international Q code for instance encodes literally hundreds of full normal language
