On which HF and/or MF amateur bands are there portions where General class licensees cannot transmit?
The correct answer is C: 80 meters, 40 meters, 20 meters, and 15 meters. On these HF and/or MF amateur bands, there are portions where General class licensees cannot transmit. These bands have segments reserved exclusively for Amateur Extra class licensees. General class operators have access to most of these bands but not the Extra-only segments. For General class operators, understanding band restrictions helps ensure legal operation. These restrictions are designed to provide additional privileges for higher license classes.
Exam Tip
General restrictions = 80m, 40m, 20m, 15m have Extra-only segments. Think 'G'eneral = 'G'ets most, but 'E'xtra gets 'E'xclusive segments on these bands. These four bands have portions reserved for Extra class only.
Memory Aid
"General restrictions = 80m, 40m, 20m, 15m. Think 'G'eneral = 'G'ets most, but 'E'xtra gets 'E'xclusive segments. These four bands have portions where General cannot transmit."
Real-World Application
As a General class operator, you can use most of the 20-meter band, but the bottom portion (14.000-14.025 MHz) is reserved for Extra class only. Similarly, 80m, 40m, and 15m have Extra-only segments. You must stay in the General-accessible portions of these bands. 10 meters has no such restrictions - General has full access.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. 60m, 30m, 17m, and 12m don't have General restrictions in the same way - these bands have different allocation structures.
Option B: Incorrect. 160m, 60m, 15m, and 12m - 160m and 60m don't have General restrictions, and the list is incomplete.
Option D: Incorrect. 80m, 20m, 15m, and 10m - 10m doesn't have General restrictions, General has full access to 10m.
