Which of the following HF amateur bands include allocations for space stations?

Deep Dive: E1D07

The correct answer is A: 40 meters, 20 meters, 15 meters, and 10 meters. Which of the following HF amateur bands include allocations for space stations are 40 meters, 20 meters, 15 meters, and 10 meters. These four HF bands have space station allocations. For amateur radio operators, this is important for satellite operation. Understanding this helps when working with satellites.

Why Other Answers Are Wrong

Option B: Incorrect. 30, 17, and 10 meters isn't correct - 40, 20, 15, and 10 meters have space allocations, not 30 and 17. 30/17 meters is wrong. Option C: Incorrect. Only 10 meters isn't correct - 40, 20, 15, and 10 meters all have space allocations. Only 10m is incomplete. Option D: Incorrect. Satellite operation isn't permitted on all HF bands - only specific bands (40, 20, 15, 10m) have space allocations. All bands is wrong.

Exam Tip

HF bands with space station allocations = 40, 20, 15, 10 meters. Think 'H'F 'S'pace = '4'0, '2'0, '1'5, '1'0 meters. These four HF bands have space station allocations. Not 30/17m, not only 10m, not all bands - just 40, 20, 15, 10 meters.

Memory Aid

HF bands with space station allocations = 40, 20, 15, 10 meters. Think 'H'F 'S'pace = '4'0, '2'0, '1'5, '1'0 meters. These four HF bands have space station allocations. Important for satellite operation.

Real-World Example

HF amateur bands with space station allocations: 40 meters, 20 meters, 15 meters, and 10 meters all have allocations for space stations. Satellites can operate on these bands. Other HF bands (30m, 17m, 12m, etc.) don't have space station allocations. These four bands (40, 20, 15, 10m) are the HF bands with space allocations.
