What is meant by the “mode” of an amateur radio satellite?
- A.Whether the satellite is in a low earth or geostationary orbit
- B.The satellite’s uplink and downlink frequency bands (correct answer)
- C.The satellite’s orientation with respect to the Earth
- D.Whether the satellite is in a polar or equatorial orbit
WhyThe "mode" of an amateur radio satellite refers to its uplink and downlink frequency bands. A satellite's "mode" describes which bands it uses for its uplink and downlink, for example Mode U/V meaning a UHF uplink and VHF downlink, answer B. Orbit type, satellite orientation, and polar versus equatorial orbit are all real satellite characteristics, but none of them is what the mode designator itself specifies.
