GLOSSARY OF TERMS

Delete all MEMORY and COUNTRY Channels (page 57)

Press ‘MEMORY’ or ‘COUNTRY.

 

• Turn off with ‘POWER’ key.

 

• Press & hold ‘POWER’ key & press ‘DELETE’ for 2

 

 

seconds.

 

• When warning appears, release ‘DELETE’ & press it

 

 

again for 2 seconds.

 

• This will clear all memory locations.

 

 

 

Mark Channels for T.Scan (page 51)

Select either MEMORY or COUNTRY.

 

Select the MEMORY or COUNTRY channel to be

 

 

marked using

 

TUNING knob or the < SELECT > key.

 

• Press the ‘TAG’ key to mark the channel.

 

 

 

T.SCAN MODE - The scan feature only works with chan-

Select MEMORY or COUNTRY mode.

nels programmed with a ‘T’ as described above. T.SCAN

Set SQUELCH to desired level.

FUNCTION (page 51)

Press T.SCAN to begin scan.

 

• Press T.SCAN again to stop scan.

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.
