intersection
You can locate your unknown position by sighting on two or more known features. This is called-
resection

deliberate offset
When transmitting a lengthy message containing encoded groups, you should make a short break after each
10 groups
The purpose of a pro-word is to
shorten voice comms
Working eastward from Greenwich, local times get
later by 1 hour
The time zones are lettered A-M. Which letter is omitted?
J
Under certain emergency conditions, radio silence is declared by radio TX, this is known as
emergency silence
Emergency radio silence can only be canceled by the
authority that imposed it
You do not have to authenticate when
making initial contact after a scheduled call sign and frequency change
When using encryption process for encoding, substitute
code values for plain text
Radio deception is divided into how many major types?
3
What type of radio deception is intrusion into the comms channels by the enemy for the purpose of deceiving or confusing?
imitative
Insertion of incorrect and misleading information into one's own comms channel to deceive a listening enemy is-
manipulative radio deception
Which type of radio deception simulates units, installations, and activities?
simulative
Which jamming technique consists of a narrow signal intended to disrupt one specific frequency or channel?
Spot jamming
Jamming technique consisting of a signal concentrated on a single frequency for only a short time is -
sweepthrough jamming
Which modulating jamming signal sounds like the rumbling of high-speed rotating machinery?
Pulse
A complete message report of a radio interference incident must be submitted to the Air Force Electronic Warfare Center within
24 hours of the initial report
The most difficult of jamming signal to distinguish. Sounds like rushing noise heard on FM receiver with the squelch off.
random noise
Short distance and all ultra-high frequency and upper very-high frequency radio transmissions are by the use of
ground waves
The component of the entire wave front that travels directly from the TX antenna to the RX antenna of a radio is called
direct wave
The portion of the radiated radio wave that reaches the RX antenna after being reflected from the surface of the Earth is called a
ground-reflected wave
