What is the National Radio Quiet Zone?
The correct answer is C: An area surrounding the National Radio Astronomy Observatory. What the National Radio Quiet Zone is an area surrounding the National Radio Astronomy Observatory. The Radio Quiet Zone protects radio astronomy from interference. For amateur radio operators, this is important for compliance. Understanding this helps ensure legal operation.
Exam Tip
National Radio Quiet Zone = area surrounding National Radio Astronomy Observatory. Think 'R'adio 'Q'uiet 'Z'one = 'R'adio 'A'stronomy 'Q'uiet. The Radio Quiet Zone protects radio astronomy from interference. Not FCC monitoring, not White Sands, not Cape Canaveral - just National Radio Astronomy Observatory.
Memory Aid
"National Radio Quiet Zone = area surrounding National Radio Astronomy Observatory. Think 'R'adio 'Q'uiet 'Z'one = 'R'adio 'A'stronomy. The Radio Quiet Zone protects radio astronomy from interference. Important compliance area."
Real-World Application
The National Radio Quiet Zone: It's an area surrounding the National Radio Astronomy Observatory (in West Virginia). This zone protects radio astronomy operations from interference. Amateur radio operations in this zone may be restricted. The Radio Quiet Zone is around the National Radio Astronomy Observatory - this is what it is.
