A typical QSO

A typical QSO (contact) in amateur radio follows a standard structure, though it can vary depending on the mode (voice, CW, digital) and the preferences of the operators. Below is an example of a voice QSO on SSB (Single Side Band):

Calling CQ (Initiating a Contact):

Station 1: "CQ CQ CQ, this is [callsign], calling CQ and standing by."

Responding to the CQ:

Station 2: "[Station 1 callsign], this is [Station 2 callsign]. Over."

Establishing the Contact:

Station 1: "[Station 2 callsign], this is [Station 1 callsign]. Thank you for the call. 
You're [signal report, e.g., 59]. 
My QTH is [location], and my name is [name]. How do you copy? Over."

Station 2: "[Station 1 callsign], this is [Station 2 callsign]. Thank you. 
You're [signal report, e.g., 59]. 
My QTH is [location], and my name is [name]. Nice to meet you! Over."

Continuing the Conversation:

Station 1: "[Station 2 callsign], thank you for the information. 
Conditions are [e.g., good, noisy]. 
I’m running [e.g., equipment description, power, antenna]. 
How about your station? Over."
Station 2: "[Station 1 callsign], I’m running [equipment details]. 
Conditions here are [e.g., clear, rainy, sunny]. Great to make contact! Over."

Ending the QSO:

Station 1: "[Station 2 callsign], thank you for the QSO. 
Hope to catch you on the air again. 73 (best regards) and good DX! 
[Station 1 callsign] clear."
Station 2: "Thank you, [Station 1 callsign]. 73, and have a great day! [Station 2 callsign] clear."

In CW (Morse code), this structure is abbreviated, with standard prosigns (e.g., "73" for best regards, "SK" for end of contact) and Q-codes (e.g., "QTH?" for location). For example:

CQ: "CQ CQ CQ DE [Station 1 callsign] K"
Reply: "[Station 1 callsign] DE [Station 2 callsign] KN"
Signal Report: "UR RST 599 599 QTH [location] NAME [name] HW? BK"
End of QSO: "73 TNX FER QSO SK"

Digital modes like FT8 follow an even more condensed exchange, typically automated by software.
