Prosign · CW procedural signal
HH prosign in Morse code
Eight dots, sent fast — 'disregard the previous group, here it is again.' The CW equivalent of crossing something out.
Morse pattern
........
Sent as one continuous shape — no inter-letter gap between the component letters.
Meaning
HH — Error / disregard
Notation
Written HH; just eight consecutive dits.
When this is used
Used the moment you make a sending error: send HH, pause, then send the corrected word. Listening operators erase the previous word mentally.
