Answer Notes
In Morse code (CW), the letter "K" is transmitted at the end of a sequence to mean "Over" or "Any station please reply". It acts as an open invitation for anyone who hears the transmission to go ahead and respond.
It is important to distinguish "K" from other similar procedural signals. For instance, "KN" is used when you specifically want only the called station to reply, and "AR" is used to indicate the end of a formal message.
