Eton E1 Automobile User Manual


 
AC Input - Alternating Current power source available
at wall outlet sockets.
AM - Signals in which the information is conveyed by
amplitude changes of the signal. Amplitude
Modulation is used for the AM broadcast bands.
AGC - Automatic Gain Control which is employed in
receivers to adjust the amount of gain in the receiver's
circuitry to prevent distortion and maintain a nearly
constant audio volume level over wide variations in
received signal strength.
CW - Continuous Wave transmission signals.Actually,
the signal is keyed on and off at precise intervals to
convey information. Morse code is the most common
CW signal.
DC Input - Direct Current power source such as is
available from batteries or regulated power supplies.
DX - Refers to stations which are unusually distant
from the receiver and are therefore frequently difficult
to receive. In the context of this manual, DX refers to a
built in preamplifier, which, when enabled, makes
these “DX”stations more readable.
Dynamic Range - Ability of the receiver to faithfully
reproduce high quality audio over a wide range of sig-
nal strength conditions - from very weak signals to
very strong signals.
Frequency - Rate of reoccurrence in hertz or cycles
per second of electromagnetic wave or carrier.
FM - Signals in which the information is conveyed by
frequency changes of the signal. Frequency Modulation
is used for the FM broadcast bands.
Electronically Switched Filter - A multi bandwidth
filter with high adjacent channel attenuationswitched
electronically.
GMT - Greenwich MeanTime.
HF - High Frequency band. This consists of the LW,
MW, and SW bands on the E1 receiver.
LCD - Liquid-Crystal Display - Low power consumption
displays used for wristwatches and information dis-
plays on many types of electronic equipment.
LSB - Lower Side Band - The lower frequency portion,
excluding the carrier, of an AM signal. A single-side-
band signal, in this case the lower sideband, contains
all of the modulation information of amplitude modu-
lation in one half the bandwidth.
RF - Radio frequency
RTTY - Radio Teletype communications.
Softkeys - Keys surrounding the display that have dif-
ferent functions under different conditions.The current
function of each individual softkey is shown on the dis-
play.
Squelch - A user controlled adjustment which mutes
the audio output below a certain signal strength.
Synchronous Detector - An amplitude modulation
detector which utilizes a replica of the original trans-
mitted carrier signal to improve the reception of weak
signals.
Synthesized - Capable of generating a large number
of different output frequencies, all related to a single,
highly stable reference source.
USB - Upper Side Band - The higher frequency portion,
excluding the carrier of an AM signal.A single side-
band signal, in this case the upper sideband, contains
all of the modulation information of amplitude modu-
lation in one half the bandwidth.
UTC - Universal Time Coordinated.
VFO - Variable Frequency Oscillator.
VHF - Very High Frequency band extends from approxi-
mately 30 MHz to 300 MHz.
