See SOS listen ) normal inter-character spaces that would occur if they were being sent as normal text. These ligatures are properly represented in print by a ligating bar or overline above the letters, indicating that they are linked and sent as one contiguous character. In Morse code, prosigns or procedural signals are dot/dash sequences that have a special meaning in a transmission: they are a form of control character. They are normally written as if they were composed of one, two or three ordinary alphabetic characters but they are sent "run together", omitting the 1 From Wikipedia, the free encyclopedia ······· · · · Prosigns for Morse code Error, correct word follows (six or more dots in a row) Error (easily identifiable by "broken" rhythm) Although these are not really prosigns, an error may be indicated by some series of Es: K, KN, and SK are also commonly used in text modes such as RTTY and PSK31. Notably, SK ("stop keying") is also used by TTY/ TDD users, though "GA" ("Go Ahead") is typed rather than "KN". Understood. Thank you. Best regards. Signing o S1: E E A couple of dits typically ends the contact. In practice, S1 and S2 would be conventional amateur callsigns uniquely identifying each of the parties to the contact.
