that retransmits on 10 meters
*
(4BB-1B.2)
What is Mode B in an amateur satellite?
B. Operation through a 70-centimeter receiver on a
satellite that retransmits on 2 meters
*
(4BB-1B.3)

*
(4BB-1C.1)
What is a linear transponder?
B. A device that receives and retransmits signals of any
mode in a certain passband
*
(4BB-1C.2)
What are the two basic types of linear transponders used in
amateur satellites?
A. Inverting and non-inverting
*
(4BB-1D.1)
Why does the downlink frequency appear to vary by several
kHz during a low-earth-orbit amateur satellite pass?
D. The distance between the satellite and ground station
is changing, causing the Doppler effect
*
(4BB-1D.2)
Why does the received signal from a Phase III amateur satellite
exhibit a fairly rapid pulsed fading effect?
A. Because the satellite is rotating
*
(4BB-1D.3)
What type of antenna can be used to minimize the effects of
spin modulation and Faraday rotation?
B. A circularly polarized antenna
*

How many horizontal lines make up a fast-scan television frame?
C. 525
*
(4BB-2A.3)
How is the interlace scanning pattern generated in a fast-scan
television system?
C. By scanning even numbered lines in one field and odd
numbered ones in the next
*
(4BB-2A.4)
What is blanking in a video signal?
B. Turning off the scanning beam while it is traveling
from right to left and from bottom to top
*
(4BB-2A.5)
What is the standard video voltage level between the sync
tip and the whitest white at TV camera outputs and modulator
inputs?

*
(4BB-2A.9)
What is the standard video level, in percent PEV, for blanking?
C. 75%
*
