*Question G1E08:
[97.313(j)] What is the maximum PEP output allowed for spread spectrum transmissions?*  

*Correct Answer is  B: 10 watts*  

### AI Response: (may contain errors)  

The correct answer to the question about the maximum Peak Envelope Power (PEP) output allowed for spread spectrum transmissions is 10 watts. Here's a breakdown of why this is the case and why the other options are incorrect.

### Explanation of the Correct Answer:
- **Correct Answer: 10 watts (Choice B)**  
  The Federal Communications Commission (FCC) regulations specify that the maximum PEP for spread spectrum transmissions in the amateur radio service is limited to 10 watts. This limit is in place to ensure that spread spectrum operations do not cause interference to other services and to maintain efficient use of the radio spectrum.

### Explanation of Incorrect Choices:
- **Choice A: 100 milliwatts**  
  This is too low for spread spectrum transmissions. While some low-power operations may use this level, it does not apply to the general spread spectrum limit.

- **Choice C: 100 watts**  
  This exceeds the allowed limit for spread spectrum transmissions. While some other modes of operation may allow higher power levels, spread spectrum is specifically limited to 10 watts.

- **Choice D: 1500 watts**  
  This is the maximum power limit for many amateur radio operations, particularly for HF (high frequency) communications, but it does not apply to spread spectrum transmissions, which are restricted to 10 watts.

### Summary:
- The maximum PEP for spread spectrum transmissions is 10 watts to prevent interference and ensure efficient spectrum use.
- Other choices either fall below or exceed this limit, making them incorrect.

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