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
Hog-Morse Hog-Morse Hog-Morse was the tendency of inexperienced telegraph operators to make errors when sending or receiving in Morse code. It is so called after one example, "home" () becoming "hog" (), which is just a subtle error in timing. The term was current in the United States in the period when American Morse code was in use. The American code was a little different to the International Morse Code currently in use. With the American code it is easier to make timing errors of this sort because there were several more symbol timings than there are in the international code.
