*Question G1A10:
[97.205(b)] What portion of the 10-meter band is available for repeater use?*  

*Correct Answer is  D: The portion above 29.5 MHz*  

### AI Response: (may contain errors)  

In the context of the 10-meter band, the correct answer to the question about the portion available for repeater use is:

**Correct Answer: The portion above 29.5 MHz**

### Explanation:

1. **Why the correct answer is correct:**
   - The 10-meter band, which ranges from 28.0 MHz to 29.7 MHz, has specific allocations for different types of operations. According to FCC regulations, the portion above 29.5 MHz is designated for repeater use. This is important for ensuring that repeaters operate in a segment of the band that minimizes interference with other amateur operations.

2. **Why the other choices are incorrect:**
   - **A: The entire band**  
     - This is incorrect because not all frequencies in the 10-meter band are allocated for repeater use. Only the segment above 29.5 MHz is designated for this purpose.
   
   - **B: The portion between 28.1 MHz and 28.2 MHz**  
     - This is incorrect as this segment is primarily used for other types of amateur operations, such as weak signal and digital modes, and is not allocated for repeater use.
   
   - **C: The portion between 28.3 MHz and 28.5 MHz**  
     - This is also incorrect because this segment is used for various amateur activities, including voice and data communications, but not specifically for repeaters.

### Useful Rules of Thumb:
- Always refer to the latest FCC regulations or band plans for specific allocations.
- Remember that repeater frequencies are typically found in the higher end of the band, which is common across many amateur bands.

This understanding of band allocations is crucial for operating within legal limits and effectively using the amateur radio spectrum.
