Electrolytic (capacitor) - a capacitor containing an acid
or salt paste (electrolyte) and is generally
polarized with a positive and negative side.
Correct polarity MUST be observed when installing
electrolytic capacitors.
FET - "Field Effect Transistor''
Ground - Refers to all points and surfaces in an electronic
device which are connected to the -DC side of the
power supply or battery. A "ground plane'' of a
circuit board is the large area of copper plating
that is common to ground. "Earth ground'' refers to
water pipes or metal grounding rods in direct
contact with Mother Earth!
IC, Integrated Circuit - A tiny plastic rectangular
block with 6, 8, 14 or more pins, containing a
silicon "chip'' which provides the equivalent of
dozens or hundreds of individual transistors and
resistors.
K - abbreviation for 1000 ohms. (10K = 10,000 ohms).
KHz - KiloHertz
MHz - MegaHertz
Inductor - A coil or loop of wire used in electronic
circuits Oscillator - see Regeneration
pF. - "picofarad,'' a tiny unit of capacitance.
megohm - one million ohms
Regeneration, Regenerative - a method of boosting the
performance of a simple detector by feeding the
detected signal back to the input of the detector
for further amplifying. This oscillation process
must be controlled carefully through the use of a
regeneration control.
RF - Radio Frequency Energy, in contrast to audio or DC.
RTTY - "Radio Teletype''
SSB, Single Sideband - a method of voice transmission
which eliminates the carrier (whistle) which you
