*Question G1A08:
[97.301(b)] Which HF bands have segments exclusively allocated to Amateur Extra licensees?*  

*Correct Answer is  B: 80 meters, 40 meters, 20 meters, and 15 meters*  

### AI Response: (may contain errors)  

In the context of the Amateur Extra license, certain segments of the HF bands are exclusively allocated to operators with this license class. Understanding these allocations is crucial for operating legally and effectively.

### Explanation:

1. **Correct Answer: 80 meters, 40 meters, 20 meters, and 15 meters**

   - **80 meters (3.5 MHz to 4.0 MHz):** The segment from 3.6 MHz to 3.7 MHz is exclusively for Amateur Extra licensees.
   - **40 meters (7.0 MHz to 7.3 MHz):** The segment from 7.125 MHz to 7.150 MHz is exclusively for Amateur Extra licensees.
   - **20 meters (14.0 MHz to 14.35 MHz):** The segment from 14.150 MHz to 14.175 MHz is exclusively for Amateur Extra licensees.
   - **15 meters (21.0 MHz to 21.45 MHz):** The segment from 21.200 MHz to 21.225 MHz is exclusively for Amateur Extra licensees.

   These exclusive segments allow Extra licensees to operate with less interference from other license classes.

2. **Why the Other Choices are Incorrect:**

   - **Choice A: All HF bands**
     - Incorrect because not all HF bands have exclusive segments for Amateur Extra licensees. Some bands, like 160 meters and 10 meters, do not have exclusive segments.

   - **Choice C: All HF bands except 160 meters and 10 meters**
     - Incorrect because it implies that all other HF bands have exclusive segments, which is not true. For example, bands like 30 meters, 17 meters, and 12 meters do not have exclusive segments for Extra licensees.

   - **Choice D: 60 meters, 30 meters, 17 meters, and 12 meters**
     - Incorrect because these bands do not have any segments exclusively allocated to Amateur Extra licensees. They are shared with other license classes.

### Key Points:

- **Exclusive Segments:** Only certain portions of the 80, 40, 20, and 15-meter bands are reserved for Amateur Extra licensees.
- **Regulatory Reference:** These allocations are specified in FCC Part 97.301(b), which outlines the frequency privileges for different license classes.

Understanding these allocations helps ensure compliance with FCC regulations and optimizes your operating experience on the HF bands.
