Skilled telegraphists must also know many traditional International Morse code communications conventions. The skills required to have efficient fast conversations with Morse comprise more than simply knowing the Morse code symbols for the alphabet and numerals. 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 92 Code, RST code, Q code, Z code as well as the use of Morse prosigns.

PASCOELA = ' Locals have plundered everything from the wreck.' However, these cyphers are typically 'fake' words six characters long, or more, used for replacing commonly used whole phrases, and are distinct from single-word abbreviations. From 1845 until well into the second half of the 20th century, commercial telegraphic code books were used to shorten telegrams, e.g. Main article: Commercial code (communications)Īlthough a few abbreviations (such as SX for 'dollar') are carried over from former commercial telegraph codes, almost all Morse abbreviations are not commercial codes.
