Answer Notes
In digital voice modes (like DMR, D-STAR, or System Fusion), users can organize into virtual rooms or 'talk groups.' To communicate with a specific group of stations, you program your radio to use that group's specific identification code or 'Talk Group ID.'
The digital system reads this code and routes your audio exclusively to other radios listening for that same ID. Distractors like CTCSS tones are incorrect because they are used to open squelch on analog repeaters, not for digital group routing.
