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
Russian Morse code Russian Morse code The Russian Morse code approximates the Morse code for the Latin alphabet. It was enacted by the Russian government in 1856. To memorize the codes, mnemonics are used, called "melodies" (напевы). A "melody" for a morse code for a character is a phrase which is sung (hence the name): the syllables with vowels а, о, ы correspond to dashes and sung long, the other syllables and the syllable "ай" correspond to dots and sung short. The "melodies" differ among various schools. The correspondence between the Cyrillic and Latin letters was later passed on into MTK-2 and subsequently
