*Question T1B04:
[97.301(a)] Which amateur band includes 146.52 MHz?*  

*Correct Answer is  D: 2 meters*  

### AI Response: (may contain errors)  

The correct answer to the question about which amateur band includes 146.52 MHz is D: 2 meters.

### Explanation:

1. **Why the correct answer is correct:**
   - The 2-meter band is defined for frequencies between 144 MHz and 148 MHz. Since 146.52 MHz falls within this range, it is part of the 2-meter band.

2. **Why the other choices are incorrect:**
   - **A: 6 meters**: The 6-meter band covers frequencies from 50 MHz to 54 MHz. Since 146.52 MHz is much higher than this range, it does not belong to the 6-meter band.
   - **B: 20 meters**: The 20-meter band operates between 14.0 MHz and 14.350 MHz. Again, 146.52 MHz is far above this range, making this choice incorrect.
   - **C: 70 centimeters**: The 70-centimeter band ranges from 420 MHz to 450 MHz. Since 146.52 MHz is below this range, it does not belong to the 70-centimeter band.

### Summary:
- The 2-meter band includes 146.52 MHz because it is within the 144-148 MHz range.
- The other bands (6 meters, 20 meters, and 70 centimeters) do not include this frequency due to their respective ranges. 

This understanding of frequency allocations is crucial for the Extra Class exam and for operating within the amateur radio bands.
