Question
The frequency allocations of which ITU region apply to radio amateurs operating in North and South America?
Answer Options
- A) Region 4
- B) Region 3
- C) Region 2
- D) Region 1
Correct Answer: C
Explanation
The International Telecommunication Union (ITU) divides the world into three regions for frequency allocation purposes. North and South America fall into ITU Region 2. This is a critical piece of information because the specific amateur frequency allocations and privileges, particularly in shared HF bands, can vary significantly between the three ITU regions.
For example, the 40\text{-meter} band has a wider voice segment in Region 2 than in Region 1 (Europe/Africa/Middle East). Knowing the correct ITU region is necessary for a US amateur operator to correctly understand their authorized frequency bands and to be aware of the band plans used by stations in other regions.
