a. line-of-sight transmission.
b. the sounds of human speech.
c. long-distance radio transmission.
d. the ultra high-frequency radio band.
2. Assume that during an engagement with Aggressor forces your .unit obtained a
transmitter calibrated in meters. With a dial scale of 3,000 to 4,500 meters, this
transmitter can be used to send signals in the
a. low frequency (LF) band.
b. medium frequency (MF) band.
c. high frequency (HF) band.
d. very high frequency (VHF) band.
3. The international classification of 32A2 emission indicates the type used for
the transmission of
a. television signals.
b. telegraph signals.
c. telephone signals.
d. facsimile signals.
ground capacitance can be minimized by the use of
a. class A bias.
b. a buffer amplifier.
c. voltage regulator tubes.
d. a neutralizing capacitor.
5. Assume that a CW transmitter includes several intermediate amplifier stages
to be used as either fundamental frequency amplifiers or as doublers. When a 10-
MHz crystal is used in the oscillator stage, the transmitter can be arranged to
transmit on a frequency of
a. 50 MHz.
c.
80 MHz.
b. 60 MHz.
d.
100 MHz.
6. When voltage amplifiers are used
in
the
RF
buffer
stages
of
a
radio
transmitter, they are operated class
