Q SIGNALS
Although used for CW, sometimes you will hear "Q Signals" used at public service events by radio operators. Q Signals were designed to shorten certain questions and answers by using standardized abbreviations.
I've included the most commonly heard Q Signals for your information.
(There's nothing worse than not understanding what someone is asking you in "Q" and being too embarrassed to ask!)
QSL Can you acknowledge receipt?
QSO Can you communicate with me?
QSY Shall I change frequency?
QTH What is your location?
