    Which ionospheric region most affects sky-wave propagation on the 6 metre band?
    The F2 region
    The F1 region
    The E region
    The D region

    B-007-07-02
    What effect does tropospheric bending have on 2-metre radio waves?
    It causes them to travel shorter distances
    It garbles the signal
    It reverses the sideband of the signal
    It lets you contact stations farther away

    B-007-07-03
    What causes tropospheric ducting of radio waves?
    Lightning between the transmitting and receiving stations
    An aurora to the north
    A temperature inversion
    A very low pressure area

    B-007-07-04
    That portion of the radiation kept close to the earth's surface due to bending in the atmosphere is called the:
    inverted wave
    ground wave
    tropospheric wave
    ionospheric wave

    B-007-07-05
    What is a sporadic-E condition?
    Patches of dense ionization at E-region height
    Partial tropospheric ducting at E-region height
