Communication and Radio Procedure
Communication and radio procedure tests clear, brief and disciplined voice procedure. The examiner looks for correct prowords, phonetic alphabet and net discipline.
Prowords
ROGER means received and understood. WILCO means will comply. OVER means I have finished and expect a reply. OUT means the conversation is ended and no reply is expected. SAY AGAIN asks for repetition; I SAY AGAIN introduces it. Do not say over and out.
Procedure
Call the station, identify yourself, give the message, and end with OVER. Use the phonetic alphabet for spelling: Alpha, Bravo, Charlie. Keep transmissions short. Do not use names, locations or unit details in clear if the net is insecure.
Worked example
You want a radio check with Sunray. Send: Sunray, this is Alpha, radio check, over. The reply: Alpha, this is Sunray, roger, over. The reasoning: call sign, identification, short content, correct ending.
Traps
Using repeat instead of say again, chatting on the net, failing to identify yourself, and saying roger when you mean yes. Radio discipline saves lives.
