*Question G1C03:
[97.303(h)(1)] What is the maximum bandwidth permitted by FCC rules for amateur radio stations transmitting on USB frequencies in the 60-meter band?*  

*Correct Answer is  A: 2.8 kHz*  

### AI Response: (may contain errors)  

The correct answer to the question about the maximum bandwidth permitted by FCC rules for amateur radio stations transmitting on USB frequencies in the 60-meter band is **A: 2.8 kHz**.

### Explanation of the Correct Answer:
- The FCC regulations specify that the maximum bandwidth for amateur radio transmissions in the 60-meter band is **2.8 kHz**. This limit is set to minimize interference with other services and ensure efficient use of the spectrum.

### Why the Other Choices are Incorrect:
- **B: 5.6 kHz**: This bandwidth exceeds the FCC limit for the 60-meter band, making it an incorrect choice.
- **C: 1.8 kHz**: While this bandwidth is less than the maximum allowed, it is not the maximum permitted, so it is also incorrect.
- **D: 3 kHz**: This option exceeds the maximum bandwidth of 2.8 kHz, making it invalid under FCC rules.

### Summary:
- The maximum bandwidth for USB transmissions in the 60-meter band is **2.8 kHz**. 
- Always refer to the latest FCC regulations for the most accurate and up-to-date information regarding bandwidth limits for amateur radio operations.
