What are Morse code abbreviations?

They are short groups used instead of frequently repeated words or phrases. CQ calls any station, QTH shares a location, and 73 closes a friendly contact.

Abbreviations, Q-codes and prosigns are not identical

Abbreviations use normal letter spacing. Q-codes are standard three-letter groups beginning with Q. Prosigns manage the flow of a message and are often sent as one continuous signal.
