What is meant by the “mode” of an amateur radio satellite?
The correct answer is B: The satellite's uplink and downlink frequency bands. What is meant by the 'mode' of an amateur radio satellite is the satellite's uplink and downlink frequency bands. Mode designates which bands are used for uplink and downlink. For amateur radio operators, this is important for satellite operation. Understanding this helps when operating through satellites.
Exam Tip
Satellite mode = uplink and downlink frequency bands. Think 'M'ode = 'M'odulation bands (uplink/downlink). Mode designates which bands are used for uplink and downlink. Not orbit type, not orientation, not orbit inclination - just uplink and downlink bands.
Memory Aid
"Satellite mode = uplink and downlink frequency bands. Think 'M'ode = 'M'odulation bands. Mode designates which bands are used for uplink and downlink. Important for satellite operation."
Real-World Application
The mode of an amateur radio satellite: It refers to the satellite's uplink and downlink frequency bands. For example, Mode A might be 2m uplink / 10m downlink, Mode B might be 70cm uplink / 2m downlink. Mode tells you which bands to use. This is what mode means - uplink and downlink frequency bands.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Whether satellite is in low earth or geostationary orbit isn't mode - mode is frequency bands, not orbit type. Orbit type isn't mode.
Option C: Incorrect. Satellite's orientation with respect to Earth isn't mode - mode is frequency bands, not orientation. Orientation isn't mode.
Option D: Incorrect. Whether satellite is in polar or equatorial orbit isn't mode - mode is frequency bands, not orbit inclination. Orbit inclination isn't mode.
