*Question G1B11:
[97.101(a)] Who or what determines “good engineering and good amateur practice,” as applied to the operation of an amateur station in all respects not covered by the Part 97 rules?*  

*Correct Answer is  A: The FCC*  

### AI Response: (may contain errors)  

The correct answer to the question is **A: The FCC**. 

### Explanation:

1. **Why the correct answer is correct:**
   - The Federal Communications Commission (FCC) is the regulatory body that oversees all communications in the United States, including amateur radio operations. According to Part 97 of the FCC rules, while there are specific regulations that must be followed, the FCC also expects operators to adhere to "good engineering and good amateur practice" in areas not explicitly covered by these rules. This means that the FCC ultimately determines what constitutes acceptable practices in amateur radio.

2. **Why the other choices are incorrect:**
   - **B: The control operator**: While the control operator is responsible for the operation of the station and must ensure compliance with FCC rules, they do not have the authority to define what constitutes good engineering and amateur practice. Their role is to follow the guidelines set forth by the FCC.
   - **C: The IEEE**: The Institute of Electrical and Electronics Engineers (IEEE) is a professional organization that develops standards and promotes advancements in technology. However, it does not have regulatory authority over amateur radio practices. Its standards may influence good engineering practices, but they are not the final authority.
   - **D: The ITU**: The International Telecommunication Union (ITU) is a specialized agency of the United Nations that coordinates global telecommunication standards and policies. While the ITU sets international regulations, the FCC is the body that enforces rules within the U.S. amateur radio context.

### Summary:
- The FCC determines what is considered "good engineering and good amateur practice" for amateur radio operations.
- The control operator, IEEE, and ITU do not have the authority to define these practices in the context of U.S. amateur radio.

This understanding is crucial for the Extra Class exam, as it emphasizes the regulatory framework governing amateur radio operations.
