Question T2A08
From subelement T2 - T2A
What is the meaning of the procedural signal “CQ”?
Why is this correct?
CQ means 'calling any station' - it's a general call inviting anyone to respond and make contact. When you transmit 'CQ CQ CQ, this is [your callsign],' you're announcing your availability to talk with any amateur who hears you. The other options are incorrect: CQ has nothing to do with quarter-hour timing, it's not a test transmission (that would be different), and it's the opposite of restricting transmissions to one station - CQ specifically invites all stations to respond.
Memory tip
Remember CQ by thinking 'Come Quick' - you're inviting anyone listening to quickly respond and start a conversation. This pattern applies whether you're on HF bands seeking distant contacts or local VHF/UHF frequencies looking for nearby stations.

CQ originated from early maritime radio as 'sécurité' (French for safety), later abbreviated. In amateur radio practice, always listen first before calling CQ to ensure frequency coordination and avoid interference. After calling CQ, wait for responses and be prepared to conduct proper station identification per Part 97 requirements. This procedural signal is fundamental to amateur radio's self-policing approach to spectrum management.
Think about it
Why do you think amateur radio uses a standardized procedural signal like CQ instead of just saying 'anyone want to talk?' in plain language?
