*Question T1C06:
[97.5(a)(2)] From which of the following locations may an FCC-licensed amateur station transmit?*  

*Correct Answer is  D: From any vessel or craft located in international waters and documented or registered in the United States*  

### AI Response: (may contain errors)  

The correct answer to the question is:

**D: From any vessel or craft located in international waters and documented or registered in the United States.**

### Explanation of the Correct Answer:
- **International Waters**: In international waters, U.S. laws apply to vessels that are documented or registered in the United States. This means that an FCC-licensed amateur station can operate from these vessels without being subject to the regulations of other countries.
- **Licensing**: The FCC license allows U.S. amateur operators to transmit from locations where they have legal authority, which includes U.S.-registered vessels in international waters.

### Why the Other Choices are Incorrect:
- **A: From within any country that belongs to the International Telecommunication Union**  
  - This is incorrect because operating from another country requires compliance with that country's regulations, not just membership in the ITU.
  
- **B: From within any country that is a member of the United Nations**  
  - Similar to choice A, this is incorrect because being a UN member does not grant permission to operate without adhering to local laws and regulations.
  
- **C: From anywhere within International Telecommunication Union (ITU) Regions 2 and 3**  
  - This is incorrect because operating in these regions still requires compliance with the specific regulations of the country in which you are transmitting. You cannot operate freely just because you are in a certain ITU region.

### Summary:
- An FCC-licensed amateur station can transmit from U.S.-registered vessels in international waters, as they are under U.S. jurisdiction.
- Always check local regulations when operating outside the U.S. to ensure compliance with the laws of the country you are in.
