*Question E1C01:
[97.303] What is the maximum bandwidth for a data emission on 60 meters?*  

*Correct Answer is  D: 2.8 kHz*  

### AI Response: (may contain errors)  

On the 60-meter band, the FCC has specific regulations regarding the maximum bandwidth for data emissions. Let's break down the correct answer and why the other options are incorrect:

### Correct Answer: D: 2.8 kHz

1. **Why the correct answer is correct:**
   - The FCC rules specify that the maximum authorized bandwidth for data emissions on the 60-meter band is 2.8 kHz. This is to ensure that transmissions do not interfere with other users on this shared band, which is also used by other services.

2. **Why the other choices are incorrect:**
   - **A: 60 Hz**  
     This bandwidth is far too narrow for typical data emissions, which require more bandwidth to transmit information effectively.
   - **B: 170 Hz**  
     This bandwidth is also too narrow for most data modes. It might be suitable for very narrow modes like CW (Morse code), but not for general data emissions.
   - **C: 1.5 kHz**  
     While this is closer to the correct answer, it is still less than the maximum allowed bandwidth. Some data modes might fit within this bandwidth, but the maximum allowed is 2.8 kHz.

### Useful Rule of Thumb:
- When operating on the 60-meter band, always ensure that your data emissions do not exceed the 2.8 kHz bandwidth limit to comply with FCC regulations and avoid interference with other users.
