A call sign is best described as which of the following?

• A. An identifier for a police unit
• B. A message or code used to identify the transmitter
• C. A password for the radio console
• D. A loud audible signal for the team

Answer: (B)

Call signs are the unique identifiers carried in radio transmissions that tell others who is transmitting. This concept is about identification of the transmitter, so the description that a call sign is a message or code used to identify the transmitter fits best. It’s what you broadcast at the start (and often end) of a transmission so dispatch and teammates know exactly who is speaking, regardless of the content of the message. It’s not a password for the radio console, not a loud audible signal, and not just a unit label—the purpose is to identify the transmitting station or person.
