Question E1D07:
[97.207] Which of the following HF amateur bands include allocations for space stations?  

Choices:  
A: 40 meters, 20 meters, 15 meters, and 10 meters  
B: 30 meters, 17 meters, and 10 meters  
C: Only 10 meters  
D: Satellite operation is permitted on all HF bands    

Correct Answer is  A: 40 meters, 20 meters, 15 meters, and 10 meters  

To the point: FCC Part 97.207 authorizes amateur space stations (satellites) only on certain HF bands. Those HF bands are 40 m, 20 m, 15 m, and 10 m.

Why the correct answer is correct
- These four HF bands (the classic “40/20/15/10”) include amateur-satellite allocations: 40 m ($\sim7$ MHz), 20 m ($\sim14$ MHz), 15 m ($\sim21$ MHz), and 10 m ($\sim28$ MHz).
- This matches the allocations permitted for space stations under 47 CFR §97.207.

Why the other choices are incorrect
- B: 30 meters, 17 meters, and 10 meters
  - 30 m and 17 m are WARC bands and do not have amateur-satellite allocations; only 10 m does.
- C: Only 10 meters
  - Too restrictive; 40 m, 20 m, and 15 m also include satellite allocations.
- D: Satellite operation is permitted on all HF bands
  - Incorrect. No satellite allocations on 80 m, 60 m, 30 m, 17 m, or 12 m.

Useful rules of thumb
- Memorize: HF satellite allocations are on the “big four” contest bands: 40 m, 20 m, 15 m, 10 m.
- No satellites on WARC bands: 30 m, 17 m, 12 m.
- Also no satellites on 60 m.
