*Question T2B07:
How can you join a digital repeater’s “talkgroup”?*  

*Correct Answer is  C: Program your radio with the group’s ID or code*  

### AI Response: (may contain errors)  

To join a digital repeater’s “talkgroup,” you need to program your radio with the specific group’s ID or code. This allows your radio to communicate on that particular talkgroup.

### Explanation of the Correct Answer:
- **C: Program your radio with the group’s ID or code**  
  This is correct because digital repeaters often use specific identifiers (IDs or codes) to manage different talkgroups. By programming your radio with the correct ID, you ensure that your transmissions are directed to the intended group.

### Explanation of Incorrect Answers:
- **A: Register your radio with the local FCC office**  
  This is incorrect because registering your radio with the FCC is not necessary for joining a talkgroup. The FCC does not manage talkgroups; it regulates the licensing of operators and stations.

- **B: Join the repeater owner’s club**  
  While joining a club may provide benefits and community support, it is not a requirement to access a digital repeater’s talkgroup. You can join a talkgroup without being a member of any club.

- **D: Sign your call after the courtesy tone**  
  Signing your call is a standard practice in amateur radio to identify yourself, but it does not relate to joining a specific talkgroup. You must first have the correct ID programmed into your radio to communicate on that talkgroup.

### Summary:
To effectively join a digital repeater’s talkgroup, ensure your radio is programmed with the correct group ID. This is essential for proper communication within that group.
