From QRZ.Com, the Icom handout, and Part 97 Of The FCC Rules -
Ham Radio Glossary - An overview of amateur radio terms.

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

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

LIon
"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

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

LoTW
See "Logbook Of The World".

Lowfer
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
http://www.altair.org/lowfer.htm (courtesy of N4YWK).

LPF

LSB
