Remember that frequencies are shared, and others can hear your conversation. Which statement is true?

• A. Frequencies are private and only your unit can hear
• B. Frequencies are shared, and others can hear your conversation
• C. Frequencies are encrypted and cannot be listened to by others
• D. Frequencies can be changed by any officer

Answer: (B)

Frequencies used for radio communication are shared among multiple users, so what you transmit on a given channel can be heard by others on the same frequency. That’s why the statement that frequencies are shared and others can hear your conversation is true—privacy isn’t guaranteed on standard channels. In practice, you should avoid transmitting sensitive information on common channels and rely on proper procedures or encryption if your system provides it.

Saying the transmission is private to your unit isn’t correct, because other units on the same frequency can listen in. The idea that frequencies are encrypted and cannot be listened to by others isn’t universally true either; encryption may be available in some systems but isn’t assumed in general. And the notion that any officer can change frequencies isn’t accurate; frequency changes typically require authorization and coordination through proper channels.
