Generally, who should respond to a station in the contiguous 48 states calling “CQ DX”?
The correct answer is C: Any stations outside the lower 48 states. Generally, stations outside the lower 48 states should respond to a station in the contiguous 48 states calling 'CQ DX'. 'CQ DX' means calling for distant stations (DX), not local stations. For amateur radio operators, this convention helps ensure DX calls are answered by appropriate stations. Understanding this helps when making or responding to DX calls.
Exam Tip
CQ DX response = stations outside lower 48 states. Think 'D'X = 'D'istant e'X'change. 'CQ DX' means calling for distant stations - stations outside the contiguous 48 states should respond. Not local stations, not just Germany, not just contests.

Real-World Application
