Click to see Hint ⬇
It involves adjusting the frequency.
Click to see Answer ⬇
Tuning - Tuning is the process of adjusting the radio's frequency to establish communication with other stations.

Question 4:

What is the internationally recognized distress signal in amateur radio communication?

Click to see Hint ⬇
It is a Morse code signal.
Click to see Answer ⬇
SOS - SOS is used as a distress signal in Morse code and is known and understood internationally.

Question 5:

What is the regulatory body responsible for amateur radio in the United States?

Click to see Hint ⬇
It is the acronym for the regulatory body.
Click to see Answer ⬇
FCC - The Federal Communications Commission (FCC) oversees and regulates amateur radio activities in the United States.

Question 6:

What is the Q-code used to request a signal report in amateur radio communication?

Click to see Hint ⬇
This Q-code is used to inquire about signal strength and readability.
Click to see Answer ⬇
QSA - QSA is the Q-code used to request a signal report, indicating the quality of the received signal.

Question 7:

What type of modulation is commonly used in single-sideband (SSB) transmissions in amateur radio?

Click to see Hint ⬇
This modulation technique suppresses the carrier and one sideband, reducing bandwidth.
Click to see Answer ⬇
Amplitude Modulation (AM) - Single-sideband (SSB) transmissions typically use Amplitude Modulation (AM) for voice communication over radio.

Question 8:

What is the term for the phenomenon where radio waves are bent due to changes in the atmosphere, allowing long-distance communication?

Click to see Hint ⬇
This phenomenon is similar to the bending of light waves in optics.
Click to see Answer ⬇
Refraction - Refraction of radio waves occurs when they are bent due to changes in the atmosphere, enabling long-distance communication.

Question 9:

What is the maximum power output allowed for amateur radio stations in the United States without specific authorization?

Click to see Hint ⬇
This power limit is specified by regulatory guidelines for amateur radio operators.
Click to see Answer ⬇
1500 watts - Amateur radio stations in the United States are generally allowed a maximum power output of 1500 watts without the need for specific authorization.

Question 10:

Which of the following is a common method for determining direction in amateur radio communication?

Click to see Hint ⬇
This method involves using specialized equipment to locate the source of a radio signal.
Click to see Answer ⬇
Direction finding (DF) - Direction finding (DF) is used in amateur radio to determine the direction from which a signal is being transmitted.

Question 11:

What is the term for the phenomenon where radio waves follow the curvature of the Earth, allowing communication over long distances?

Click to see Hint ⬇
This phenomenon is related to the behavior of radio waves in the Earth's atmosphere.
Click to see Answer ⬇
Tropospheric ducting - Tropospheric ducting is a propagation mode in which radio waves are guided along the Earth's surface due to the presence of a duct, or a region of enhanced refractive index, in the lower atmosphere.

Question 12:

What is the term for the process of decoding a digital signal by adjusting the phase, frequency, and amplitude?

Click to see Hint ⬇
This process involves extracting the original information from a modulated carrier signal.
Click to see Answer ⬇
Demodulation - Demodulation is the process of extracting the original information-bearing signal from a modulated carrier wave.

Which of the following is a common method for reducing interference from other signals on a frequency in amateur radio communication?

Click to see Hint ⬇
This method involves selectively allowing a specific range of frequencies to pass through.
Click to see Answer ⬇
Bandwidth filtering - Bandwidth filtering involves selectively allowing a specific range of frequencies to pass through while rejecting others, thereby reducing interference from unwanted signals.

Question 14:

What is the term for the process of adjusting the timing of a received signal to align it with a local reference clock?

Click to see Hint ⬇
This process involves aligning the timing of a received signal with a local reference clock.
Click to see Answer ⬇
Synchronization - Synchronization is the process of aligning the timing of a received signal with a local reference clock to ensure accurate reception and decoding of the signal.
