Question
How is a specific group of stations selected on a digital voice transceiver?
Answer Options
- A) By choosing the correct CTCSS tone
- B) By choosing the correct DCS code
- C) By choosing the correct talkgroup
- D) By choosing the correct digital format
Correct Answer: C
Explanation
In digital voice (DV) modes (like DMR, D-STAR, etc.), the method for logically separating conversations on a single digital channel is the talkgroup (T8D02). A talkgroup is an assigned code or ID number that is added to the digital data stream of a transmission.
When you select a talkgroup on your radio, your transmission is tagged with that group’s ID. Any other radio configured to listen to that talkgroup will receive your message, while radios listening to other talkgroups on the same frequency will remain silent, effectively filtering out other conversations. This is the digital equivalent of using a CTCSS tone (T2B02).
