How is a specific group of stations selected on a DMR digital voice transceiver?

Answer: C. By entering the group's identification code

On DMR, groups of stations are organized into talkgroups. You select a group by entering the group's identification code (the talkgroup ID). CTCSS tones are used on analog FM, not for choosing DMR talkgroups.

Tip: DMR talkgroup = pick it by ID number.
