    Practice


    B-007-01-01
    What type of propagation usually occurs from one hand- held VHF transceiver to another nearby?
    Tunnel propagation
    Sky-wave propagation
    Auroral propagation
    Line-of-sight propagation

    B-007-01-02
    How does the range of sky-wave propagation compare to ground- wave propagation?
    It is much shorter
    It is about the same
    It depends on the weather
    It is much longer

    B-007-01-03
    When a signal is returned to earth by the ionosphere, what is this called?
    Tropospheric propagation
    Ground-wave propagation
    Sky-wave propagation
    Earth-moon-earth propagation

    B-007-01-04
    How are VHF signals propagated within the range of the visible horizon?
    By direct wave
    By sky wave
    By plane wave
    By geometric wave

    B-007-01-05
    Skywave is another name for:
    ionospheric wave
    tropospheric wave
    ground wave
    inverted wave

    B-007-01-06
    That portion of the radiation which is directly affected by the surface of the earth is called:
    tropospheric wave
    ionospheric wave
    inverted wave
    ground wave

    B-007-01-07
    At HF frequencies, line-of-sight transmission between two stations uses mainly the:
    troposphere
    skip wave
    ionosphere
    ground wave

    B-007-01-08
    The distance travelled by ground waves:
    depends on the maximum usable frequency
    is more at higher frequencies
    is less at higher frequencies
    is the same for all frequencies

    B-007-01-09
    The radio wave which follows a path from the transmitter to the ionosphere and back to earth is known correctly as the:
    F layer
    surface wave
    ionospheric wave
    skip wave

    B-007-01-10
    Reception of high frequency (HF) radio waves beyond 4000 km is generally possible by:
    ground wave
    ionospheric wave
    skip wave
    surface wave
