From which of the following locations may an FCC-licensed amateur station transmit?
The correct answer is D: From any vessel or craft located in international waters and documented or registered in the United States. According to FCC Part 97.5, an FCC-licensed amateur station may transmit from U.S.-registered vessels or aircraft in international waters or airspace. This allows amateurs to operate from ships, boats, or aircraft that are U.S.-registered when they are outside U.S. territorial waters or airspace.
This provision allows amateur operators to use their licenses while traveling on U.S.-registered vessels (like cruise ships, cargo ships, or private boats) or aircraft when in international waters or airspace. The key requirements are that the vessel or craft must be documented or registered in the United States, and it must be in international waters/airspace (not within another country's territory). Operating from within another country's territory would require that country's permission or a reciprocal operating agreement.
Exam Tip
Operating location = U.S. vessels in international waters. Remember: You can operate from U.S.-registered vessels/aircraft in international waters or airspace, but not automatically from within other countries.

Real-World Application
You're on a cruise ship that's registered in the United States. When the ship is in international waters (outside any country's territorial limits), you can operate your amateur station using your FCC license. However, when the ship enters another country's territorial waters, you must cease operations unless that country has a reciprocal operating agreement with the U.S.

Why Other Options Are Wrong
Option A: Incorrect. You cannot automatically operate from within any ITU member country. Operating from within another country requires that country's permission or a reciprocal agreement.
Option B: Incorrect. UN membership doesn't grant operating privileges. You need specific authorization to operate from within another country.
Option C: Incorrect. ITU Regions 2 and 3 don't grant automatic operating privileges. You still need proper authorization to operate from within another country's territory.
