On which of the following frequencies are General class licensees prohibited from operating as control operator?
The correct answer is A: 7.125 MHz to 7.175 MHz. General class licensees are prohibited from operating as control operator on 7.125 MHz to 7.175 MHz. This frequency range is reserved exclusively for Amateur Extra class licensees. General class operators have access to other portions of the 40-meter band but not this segment. For General class operators, understanding these restrictions helps ensure legal operation. This is part of the Extra-only segments on various bands.
Exam Tip
General prohibited = 7.125-7.175 MHz (40 meters). Think 'G'eneral = 'G'ets most of 40m, but 'E'xtra gets 'E'xclusive 7.125-7.175 MHz. This is the Extra-only segment on 40 meters where General cannot operate.
Memory Aid
"General prohibited = 7.125-7.175 MHz. Think 'G'eneral = 'G'ets most, but 'E'xtra gets 'E'xclusive 7.125-7.175 MHz on 40 meters. This is the Extra-only segment."
Real-World Application
As a General class operator, you can use most of the 40-meter band, but the segment from 7.125 to 7.175 MHz is off-limits - it's reserved for Extra class only. You must stay above or below this range. Operating in this segment would violate your license privileges.
Key Concepts
Why Other Options Are Wrong
Option B (28.000-28.025 MHz): Incorrect. General class has access to this portion of 10 meters. This isn't a General restriction.
Option C (21.275-21.300 MHz): Incorrect. General class has access to portions of 15 meters, though not all. This specific range isn't the prohibited segment.
Option D: Incorrect. Since B and C are not correct, 'all of the above' cannot be correct. Only 7.125-7.175 MHz is the General prohibition.
