*Question T1A09:
[97.3(a)(22)] Who selects a Frequency Coordinator?*  

*Correct Answer is  C: Amateur operators in a local or regional area whose stations are eligible to be repeater or auxiliary stations*  

### AI Response: (may contain errors)  

The correct answer to the question about who selects a Frequency Coordinator is:

**C: Amateur operators in a local or regional area whose stations are eligible to be repeater or auxiliary stations.**

### Explanation of the Correct Answer:
- Frequency Coordinators are typically selected by local amateur radio operators who are involved in the use of repeaters and auxiliary stations. This group understands the local communication needs and can effectively manage frequency usage to minimize interference and optimize communication.

### Why the Other Choices are Incorrect:
- **A: The FCC Office of Spectrum Management and Coordination Policy**
  - This choice is incorrect because the FCC does not directly select Frequency Coordinators. Instead, they delegate this responsibility to the amateur community.

- **B: The local chapter of the Office of National Council of Independent Frequency Coordinators**
  - This option is misleading. While there are organizations that may assist in coordination, the actual selection of Frequency Coordinators is done by local amateur operators, not a specific chapter of a national organization.

- **D: FCC Regional Field Office**
  - Similar to choice A, the FCC Regional Field Office does not select Frequency Coordinators. Their role is more about regulation and enforcement rather than the grassroots coordination of frequencies.

### Summary:
- Frequency Coordinators are chosen by local amateur operators to ensure effective use of frequencies for repeaters and auxiliary stations. This process is community-driven, reflecting the needs and expertise of local operators. 

Understanding this structure is crucial for the Extra Class exam, as it emphasizes the role of amateur operators in self-regulating their frequency usage.
