What does the term key click mean?
B. The clicking noise from an excessively square CW keyed
waveform
*
(2AH-2.2)
How can key clicks be eliminated?
D. By using a key-click filter
*
(2AH-3.1)
What does the term chirp mean?

transmitter is keyed
*
(2AH-3.2)
What can be done to the power supply of a CW transmitter to
avoid chirp?
B. Regulate the power supply output voltages

What is the 4th harmonic of a 7160-kHz signal?
A. 28,640 kHz
*
(2AH-5.2)
You receive an FCC Notice of Violation stating that your station
was heard on 21,375 kHz. At the time listed on the notice, you
were operating on 7125 kHz. What is a possible cause of this
violation?
C. Your transmitter was radiating excess harmonic signals
*
(2AH-6.1)
What may happen to body tissues that are exposed to large
amounts of UHF or microwave RF energy?
A. The tissue may be damaged because of the heat produced
*
(2AH-6.2)
What precaution should you take before working near a high-gain
UHF or microwave antenna (such as a parabolic, or dish antenna)?
C. Be certain the transmitter cannot be operated

(2AH-6.3)
You are installing a VHF or UHF mobile radio in your vehicle.
What is the best location to mount the antenna on the vehicle to
minimize any danger from RF exposure to the driver or
passengers?
A. In the middle of the roof
*
(2AH-7.1)
You discover that your tube-type transmitter poweramplifier is
radiating spurious emissions. What is the most likely cause of
this problem?
C. Improper neutralization
*
(2AH-7.2)
Your transmitter radiates signals outside the amateur band where
you are transmitting. What term describes this radiation?
D. Spurious emissions
*
(2AH-7.3)
What problem can occur if you operate your transmitter without
the cover and other shielding in place?
A. Your transmitter can radiate spurious emissions
*
(2AH-7.4)
What type of interference will you cause if you operate your SSB
transmitter with the microphone gain adjusted too high?
B. You may cause splatter interference to other stations
operating on nearby frequencies
*
(2AH-7.5)
What may happen if you adjust the microphone gain or deviation
control on your FM transmitter too high?
B. You may cause interference to other stations operating on
nearby frequencies
*
(2AH-7.6)
What type of interference can excessive amounts of speech
processing in your SSB transmitter cause?
B. You may cause splatter interference to other stations
operating on nearby frequencies
*
