T8B07:

With regard to satellite communications, what is Doppler shift?

1. A change in the satellite orbit
2. A mode where the satellite receives signals on one band and transmits on another
3. An observed change in signal frequency caused by relative motion between the satellite and the earth station
4. A special digital communications mode for some satellites

T8B08:

What is meant by the statement that a satellite is operating in mode U/V?

T8B12:

Which of the following is a good way to judge whether your uplink power is neither too low nor too high?

1. Check your signal strength report in the telemetry data
2. Listen for distortion on your downlink signal
3. Your signal strength on the downlink should be about the same as the beacon
4. All of these choices are correct
