The time it takes for a satellite to complete one revolution around the Earth

The point of maximum height of a satellite's orbit

The point of minimum height of a satellite's orbit

The time it takes for a satellite to travel from perigee to apogee

2016-E2A04: What is meant by the term mode as applied to an amateur radio satellite?

The satellite's uplink and downlink frequency bands

The type of signals that can be relayed through the satellite

The satellite's orientation with respect to the Earth

Whether the satellite is in a polar or equatorial orbit

2016-E2A05: What do the letters in a satellite's mode designator specify?

The uplink and downlink frequency ranges

Power limits for uplink and downlink transmissions

The location of the ground control station

The polarization of uplink and downlink signals

435 MHz - 438 MHz

144 MHz - 146 MHz

50.0 MHz - 50.2 MHz

29.5 MHz - 29.7 MHz

2016-E2A07: Which of the following types of signals can be relayed through a linear transponder?

All of these choices are correct

FM and CW


PSK and Packet

2016-E2A08: Why should effective radiated power to a satellite which uses a linear transponder be limited?

To avoid reducing the downlink power to all other users

To prevent creating errors in the satellite telemetry

To prevent the satellite from emitting out-of-band signals

To avoid interfering with terrestrial QSOs

2016-E2A09: What do the terms L band and S band specify with regard to satellite communications?

The 23 centimeter and 13 centimeter bands

The 2 meter and 70 centimeter bands

FM and Digital Store-and-Forward systems

Which sideband to use

2016-E2A10: Why may the received signal from an amateur satellite exhibit a rapidly repeating fading effect?

Because the satellite is spinning

Because of ionospheric absorption

Because of the satellite's low orbital altitude

Because of the Doppler Effect

2016-E2A11: What type of antenna can be used to minimize the effects of spin modulation and Faraday rotation?

A circularly polarized antenna

A linearly polarized antenna

An isotropic antenna

A log-periodic dipole array

2016-E2A12: What is one way to predict the location of a satellite at a given time?

By calculations using the Keplerian elements for the specified satellite

By means of the Doppler data for the specified satellite

By subtracting the mean anomaly from the orbital inclination

By adding the mean anomaly to the orbital inclination

2016-E2A13: What type of satellite appears to stay in one position in the sky?
