Technician exam question T4B09
Subelement T4, AMATEUR RADIO PRACTICES· Group T4B
How is a specific group of stations selected on a DMR digital voice transceiver?
- A.By retrieving the frequencies from transceiver memory
- B.By enabling the group’s CTCSS tone
- C.By entering the group’s identification code (correct answer)
- D.By inserting a five-pin, pre-programmed code plug
WhyA specific group of stations is selected on a DMR digital voice transceiver by entering the group's identification code. DMR organizes stations into talkgroups, so selecting a specific group of stations to talk to means entering that talkgroup's identification code into the radio, answer C. Frequencies alone (A) don't select a talkgroup, CTCSS (B) is an analog FM squelch tone unrelated to DMR's digital talkgroup system, and a code plug (D) is the overall configuration loaded into the radio, not something inserted per contact to choose a group.
