Morse code abbreviations
Morse code abbreviations differ from prosigns for Morse Code in that they observe normal interletter spacing; that is, they are not "run together" the way prosigns are. 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"[1]. S2: S1 DE S2 = R TU CUAGN 73 S1 DE S2 SK Understood. Thank you. Best regards. (signing With heavy use of the Q code and Morse Code Abbreviations, surprisingly meaningful conversations can be had. Note that very few English words have been used ("is" and "name"), only abbreviations. S1 and S2 might not speak the same native language. Of course, real rag-chewing (lengthy conversations) cannot be done without a common language. On the worldwide amateur bands this is often English. Contesters often use a very specialized and even shorter format for their contacts. Their purpose is to process as many contacts as possible in a limited time (e.g. 100-150 per hour).
An amateur radio conversation in Morse code
The skill to have sensible conversations with Morse is more than knowing just the alphabet. To make communication efficient, there are many internationally agreed patterns of communication. A sample CW conversation between station 1 (S1) and station 2 (S2) S1:
