The frequency allocations of which ITU region apply to radio amateurs operating in North and South America?
The correct answer is C: Region 2. The frequency allocations of ITU Region 2 apply to radio amateurs operating in North and South America. ITU divides the world into three regions, and Region 2 covers the Americas. For amateur radio operators in North and South America, Region 2 allocations determine what frequencies are available. Understanding this helps when planning operations and understanding why allocations differ from other parts of the world.
Exam Tip
North/South America = ITU Region 2. Think 'A'mericas = 'R'egion '2'. ITU Region 2 covers North and South America. Region 1 is Europe/Africa, Region 3 is Asia/Pacific. Not Region 4 (doesn't exist).
