Talk group refers to virtual radio channels created for/by a ______.

• A. Analog system
• B. Trunked Radio System (TRS)
• C. Private network
• D. Single-channel system

Answer: (B)

In a trunked radio system, talk groups are virtual channels created for/by a specific group or function. The system shares a pool of physical channels and uses a control channel to assign a free channel when someone talks, but the transmission is addressed to a designated talk group. This lets many different groups or units use the same frequencies without stepping on each other. Analog systems use fixed, physical channels, and single-channel or private networks don’t organize traffic into these virtual groups, so the concept specifically fits TRS.
