In relationship to direction finding (DF), as a spectrum operation technician, what must you decipher to help locate and resolve EMI?
-
Interference reports and customer information.
-
Radio frequency guides and publications.
-
Supplemental and Closings report only.
-

What made trunking possible in land mobile radio (LMR) systems?
-
Better antennas.
-
Microprocessors.
-
Frequency diversity.
-

Barrage jammers are limited to narrow bandwidths because they
-
Need large antennas.
-
Require large amounts of gain.
-
Require large amounts of power.
-
Can operate only in low frequencies.
Correct Answer
A. Require large amounts of power.Explanation
Barrage jammers are limited to narrow bandwidths because they require large amounts of power. This is because the jamming signal needs to overpower the original signal in order to disrupt communication effectively. By using large amounts of power, the jammer can generate a strong signal that can interfere with the targeted frequencies. However, this high power requirement limits the bandwidth that can be jammed, as it becomes increasingly difficult to generate and sustain high power levels across a wide range of frequencies.Rate this question:

The presence or absence and height above Earth of the F1 and F2 ionospheric layers vary with the position of the
-
Sun.
-
Earth.
-
Moon.
-
Earth’s magnetic flux.
Correct Answer
A. Sun.Explanation
The presence or absence and height above Earth of the F1 and F2 ionospheric layers vary with the position of the Sun. The ionospheric layers are formed due to the interaction between solar radiation and the Earth's atmosphere. The Sun is the primary source of solar radiation, and its position in the sky directly affects the ionization levels and height of the ionospheric layers. Therefore, changes in the position of the Sun will cause variations in the presence, absence, and height of the F1 and F2 ionospheric layers.Rate this question:

Correct Answer
A. Direct.Explanation
The component of the ground wave that travels directly from the transmit antenna to the receive antenna is called the direct wave. This wave follows a straight line path and does not interact with the ground or any other objects. It is the shortest and fastest path between the two antennas, resulting in the strongest signal strength.Rate this question:

You can make a long-wire antenna directional by
-
Switching propagation modes.
-
Placing a balun on the antenna input.
-
Decreasing the power output of the radio.
-
Placing a terminating device at the distant station end of the antenna.
Correct Answer
A. Placing a terminating device at the distant station end of the antenna.Explanation
Placing a terminating device at the distant station end of the antenna can make a long-wire antenna directional. This is because the terminating device absorbs the energy that is not radiated in the desired direction, preventing it from reflecting back towards the source. By effectively terminating the antenna, the signal is focused in the desired direction, increasing the antenna's directivity and making it more directional.Rate this question:

What is the best way to counter barrage jamming?
-
Decrease the operating power.
-
Increase the operating power.
-
Increase the bandwidth.
-
Decrease the bandwidth.
Correct Answer
A. Increase the operating power.Explanation
Increasing the operating power is the best way to counter barrage jamming. Barrage jamming is a type of electronic warfare where a wide range of frequencies are jammed simultaneously, making it difficult for the intended signal to be received. By increasing the operating power, the intended signal is amplified, allowing it to overcome the jamming interference and be received more effectively. This increased power helps to overpower the jamming signals and maintain communication or transmission.Rate this question:

Radio horizon distance equates to what?
-
Line of sight.
-
Line of sight and over the horizon.
-
Distance of travel of one wavelength of a radio wave.
-
A distance equal to approximately 15 percent greater than the optical horizon distance.
Correct Answer
A. A distance equal to approximately 15 percent greater than the optical horizon distance.Explanation
The radio horizon distance refers to the maximum distance at which a radio signal can be transmitted and received without any obstacles or interference. It is typically greater than the optical horizon distance due to the nature of radio waves and their ability to diffract and bend around obstacles. The correct answer states that the radio horizon distance is approximately 15 percent greater than the optical horizon distance, indicating that radio signals can travel further than what can be seen with the naked eye.Rate this question:

Which occurrence is not an irregular variation of the ionosphere?
-
Diurnal.
-
Solar flare.
-
Sporadic E.
-

Correct Answer
A. Diurnal.Explanation
Diurnal variation refers to the regular daily changes in the ionosphere due to the Sun's radiation. It is a predictable pattern that occurs every day, with ionization levels increasing during the day and decreasing at night. On the other hand, solar flares, sporadic E, and ionospheric storms are all irregular variations of the ionosphere that occur due to external factors such as solar activity, weather conditions, and geomagnetic disturbances. Therefore, diurnal is the only occurrence mentioned that is not considered an irregular variation of the ionosphere.Rate this question:

What is the worst type of antenna to use for sky wave circuits?
-
Whip.
-
Long-wire.
-
Inverted V.
-
Rotatable log periodic antenna (RLPA).
Correct Answer
A. Whip.Explanation
A whip antenna is the worst type of antenna to use for sky wave circuits because it is vertically polarized and has a low radiation angle. Sky wave propagation relies on signals being reflected off the ionosphere, and a low radiation angle will result in a significant portion of the signal being absorbed by the ground instead of being reflected back. Additionally, whip antennas have a limited radiation pattern and are less efficient at transmitting and receiving signals over long distances.Rate this question:

What irregular ionospheric variation can actually help HF communications by letting stations propagate on unusually high frequencies or allow sky wave propagation to close stations?
-
Sporadic E.
-
Solar flares.
-
Ionospheric storms.
-
Sudden ionospheric disturbances.
Correct Answer
A. Sporadic E.Explanation
Sporadic E is an irregular ionospheric variation that can help HF communications by allowing stations to propagate on unusually high frequencies or enabling sky wave propagation to close stations. Sporadic E is a phenomenon where patches of dense ionization form in the E region of the ionosphere, which is normally too weak for HF communication. These patches can reflect HF signals, allowing them to travel longer distances and at higher frequencies than usual. This can enhance HF communication capabilities and improve the range and quality of transmissions.Rate this question:

Polar orbit is used for intelligence collection, weather services, and navigation because it covers more points on Earth than other types of satellites. This is because a polar orbit passes over the Earth's poles and covers the entire surface of the Earth as it rotates. In contrast, inclined, equatorial, and synchronous orbits have limitations in terms of coverage and may not be able to reach certain areas of the Earth.Rate this question:
