• Ham Radio Glossary (L)

    From Daryl Stout@1:2320/33 to All on Mon Apr 10 00:03:32 2023
    From QRZ.Com, the Icom handout, and Part 97 Of The FCC Rules -
    Ham Radio Glossary - An overview of amateur radio terms.

    Low Frequency. The frequency range from 30 to 300 Mhz signals.

    Slang term, often referring to an amateur radio operator with very poor practices and manners.

    "Lithium-Ion". A type of rechargable battery commonly used with radio equipment. It has better capacity that the Ni-Cad (Nickel Cadmium),
    Ni-MH (Nickel Metal Hydride), etc. -- and it has no memory effect after repeated non-full charge/discharge cycles.

    Line A. Begins at Aberdeen, WA, running by great circle arc
    to the intersection of 48 degrees N, 120 degrees; W, thence along
    parallel 48 degrees; N, to the intersection of 95 degrees; W,
    thence by great circle arc through the southernmost point of
    Duluth, MN, thence by great circle arc to 45 degrees N, 85 degrees
    W, thence southward along meridian 85 degrees W, to its intersection
    with parallel 41 degrees N, thence along parallel 41 degrees N, to
    its intersection with meridian 82 degrees W, thence by great circle
    arc through the southernmost point of Bangor, ME, thence by great
    circle arc through the southernmost point of Searsport, ME, at
    which point it terminates.

    Local control
    The use of a control operator who directly manipulates the operating adjustments in the station to achieve compliance with the FCC Rules.

    Logbook Of The World
    The ARRL Logbook Of The World system is a repository of log records
    submitted by users from around the world. When both participants in a
    QSO submit maching QSO records to LoTW, the result is a QSL that can
    be used for ARRL award credit. Other electronic QSL systems, such as
    EQSL, can NOT be used for ARRL awards. For more information, go to http://www.arrl.org/lotw

    "Loss of Signal" from a satellite; occurs when the satellite becomes "invisible" to the antenna as it goes below the horizon.

    See "Logbook Of The World".

    One who experiments with radio communications at unusually low frequencies (typically 1750 Meters, which is 160-190 kHz and can be used under FCC
    Part 15). For more information, take a look at
