CW Prosigns, Q Codes and Abbreviations
THEME

CW

Prosigns, Q codes, and abbreviations for amateur Morse. Wording follows ITU procedural signals and the ARRL on-air set.

LettersFiguresPunctuationProsignsQ codesAbbreviations

Pressing a letter, figure, punctuation mark, prosign, Q code, or abbreviation plays it at 15 WPM with a 700 Hz tone. The code is not shown, because Morse is to be listened to, not read. This page does not show the code.

Prosigns

A prosign is one Morse character. Where the name is two or three letters, those letters are run together with no letter space between them. K and SK are sent as single prosigns: SK is run together, and K is the single letter K, not separate letters and not a word spelled out. A bar over the letters means the same thing.

SignalMeaning
End of the message. Often written with a bar, or as +.
Wait. Stand by.
Break. A quick handover, or an interruption, without a full callsign exchange.
Separator between thoughts, or a new sentence. Often written as =.
Closing the station. Going off the air.
Go ahead. Any station may transmit. The single letter K, not spelled out.
Go ahead, only the station I am working. Others should not answer.
End of the contact. Sent as one character, not as S then K. Same signal as VA.
Distress. The three letters are run together. Not a calling or practice signal.
Eight dits, sent as one character. Disregard the last word. Operators often send a shorter string of dits, and it is still read as an error.

Q codes

These are the Q codes heard in ordinary CW contacts, not the full ITU list. A question mark makes the question. Without it, the same code is the statement. Each line is the question, then the statement.
