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 Mean Time.

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.
