*Question G1A04:
[97.303(h)] Which of the following amateur bands is restricted to communication only on specific channels, rather than frequency ranges?*  

*Correct Answer is  D: 60 meters*  

### AI Response: (may contain errors)  

The correct answer to the question is **60 meters**. Here's why:

1. **Why 60 meters is correct:**
   - The 60-meter band is unique among amateur bands because it is restricted to specific channels rather than a continuous frequency range. In the U.S., operators are allowed to use only five specific frequencies within the 60-meter band, which are designated for amateur use. This means that communication must occur on these specific channels, making it different from other bands that allow operation across a range of frequencies.

2. **Why the other choices are incorrect:**
   - **11 meters:** This band is primarily used for CB (Citizens Band) radio and does not have specific channel restrictions for amateur use. It operates over a continuous frequency range.
   - **12 meters:** The 12-meter band allows operation over a range of frequencies (24.890 to 24.930 MHz) without specific channel restrictions, making it a continuous band.
   - **30 meters:** Similar to the 12-meter band, the 30-meter band (10.100 to 10.150 MHz) is also a continuous band and does not have specific channels. It is primarily used for digital modes and CW (Continuous Wave) operation.

3. **Useful rules of thumb:**
   - Remember that bands with specific channels (like 60 meters) are often subject to more stringent regulations and limitations compared to bands that allow operation over a range of frequencies.
   - Always check the latest regulations and band plans for any updates or changes regarding frequency usage and restrictions.

This understanding will help you navigate the rules and regulations of amateur radio bands effectively.
