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

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

### AI Response: (may contain errors)  

In the context of amateur radio, space stations refer to satellites or other space-based transmitters that operate on amateur radio frequencies. The Federal Communications Commission (FCC) has specific allocations for these operations on certain HF bands.

### Explanation:

1. **Correct Answer: 40 meters, 20 meters, 15 meters, and 10 meters**

   - These bands are specifically allocated for space station operations in the amateur radio service. The FCC regulations allow for satellite communication on these bands, making them suitable for space station operations.

2. **Why the Other Choices are Incorrect:**

   - **Choice A: 40 meters, 20 meters, 15 meters, and 10 meters**  
     - This is the correct answer, as these bands are indeed allocated for space station operations.

   - **Choice B: 30 meters, 17 meters, and 10 meters**  
     - The 30-meter and 17-meter bands are not allocated for space station operations. Only the 10-meter band from this list is correct.

   - **Choice C: Only 10 meters**  
     - While the 10-meter band is allocated for space station operations, it is not the only band. The 40-meter, 20-meter, and 15-meter bands are also included.

   - **Choice D: Satellite operation is permitted on all HF bands**  
     - This is incorrect because not all HF bands are allocated for space station operations. Only specific bands, as mentioned in the correct answer, are designated for this purpose.

### Useful Rule of Thumb:

- **Space Station Allocations:**  
  When considering HF bands for space station operations, remember that not all HF bands are available. Focus on the 40-meter, 20-meter, 15-meter, and 10-meter bands for these purposes.

Understanding these allocations is crucial for ensuring compliance with FCC regulations and for effective communication with space stations in the amateur radio service.
