Question
Which of the following HF amateur bands include allocations for space stations?
Answer Options
- 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: A
Explanation
Space stations (amateur satellites) require specific frequency allocations to operate their transponders and beacons. While satellite operations are most common on VHF and UHF bands, the HF (High Frequency) bands also have allocations. However, it is not all HF bands, but a specific subset.
For space station operation, the FCC rules authorize specific segments in the 40 meters, 20 meters, 15 meters, and 10 meters bands. These segments are set aside to facilitate orbital communications, though the actual frequencies used are generally coordinated to avoid interference with terrestrial operations, reflecting the primary/secondary status of the amateur service.
