How can you join a digital repeater’s “talkgroup”?
The correct answer is C: Program your radio with the group's ID or code. To join a digital repeater's talkgroup, you need to program your radio with the talkgroup's identification number or code. This is done through your radio's programming software or menu system.
Digital repeaters (like DMR, D-STAR, or System Fusion) use talkgroups to organize communications. Each talkgroup has a unique ID number. When you program your radio with a talkgroup ID and transmit, your signal is routed to that talkgroup. Other operators listening to the same talkgroup will hear your transmission. This is similar to selecting a channel on an analog repeater, but uses digital IDs instead.
Exam Tip
Join talkgroup = Program group ID. Remember: To join a digital repeater talkgroup, program your radio with the talkgroup's ID or code. This is done through radio programming, not registration or club membership.

Real-World Application
You want to join a local DMR repeater's talkgroup 3100 (a regional talkgroup). You use your radio's programming software to add talkgroup 3100 to your radio's codeplug. When you select this talkgroup and transmit, your signal is routed to talkgroup 3100, and other operators monitoring that talkgroup hear your transmission.

Why Other Options Are Wrong
Option A: Incorrect. You don't register your radio with the FCC office. Talkgroup access is controlled by programming your radio, not by FCC registration.
Option B: Incorrect. Joining a club is not required. You just need to program the talkgroup ID into your radio.
Option D: Incorrect. Signing your call after the courtesy tone is for identification, not for joining a talkgroup. Talkgroup selection is done through programming.
