    Program SKYTRIG - SKYWAVE TRIGONOMETRY

    With an input of elevation angle, layer height and critical frequency,
    the program calculates skywave path distance, groundpath distance,
    spreading (dispersion) loss, field strength from a 100 watt
    transmitter, and the MUF.

    The program can be used for guidance on the low MUF's and the geometry
    of near vertical incidence radio paths over short distance
    groundpaths.

    Elevation angle is NOT the angle at which an antenna radiates the
    strongest signal. It is the angle of the path taken by the radio wave
    between two places on the Earth's surface and is nothing to do with an
    antenna.

    The program notes provide some elementary information on the heights
    and behaviour of the various ionospheric layers in sunlight and in
    darkness. Also on factors which affect received field strength such as
    operating frequency being greater than MUF.

    Download in a few seconds program SKYTRIG from website below.
    Filesize = 42 kilo-bytes. Run immediately. Or you can open/run it
    without downloading.
