GLOSSARY OF TERMS

1)AC Input - Alternating Current power source available at wall outlet sockets.

2)AM - Signals in which the information is conveyed by amplitude changes of the signal. Amplitude Modulation is used for the AM broadcast bands.

3)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.

4)Attenuation - Loss, as applied in the text of this

manual, added prior to the input stages of the receiver to reduce the level of very strong signals that may occur on

certain bands, in certain locations, at certain times or a combination of all three factors. Each 10 dB (decibel)

step reduces the power of the received signal by a factor of ten.

5)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.

6)DC Input - Direct Current power source such as is available from batteries or regulated power supplies.

7)Dynamic Range - Ability of the receiver to faithfully

reproduce high quality audio over a wide range of signal strength conditions - from very weak signals to very strong signals.

8)Frequency - Rate of reoccurrence in hertz or cycles per second of an electromagnetic wave or carrier.

9)FM - Signals in which the information is conveyed by frequency changes of the signal. Frequency Modulation is used for the FM broadcast bands.

10)Electronically Switched Filter - A multi-bandwidth

filter with high adjacent channel attenuation switched electronically.

11)GMT - Greenwich Mean Time.

12)HF - High Frequency band extends from approximately 1.5 MHz to 30 MHz.

13)LCD - Liquid-Crystal Display - Low power consump tion displays used for wristwatches and information displays on many types of electronic equipment.

14)LSB - Lower Side Band - The lower frequency portion, excluding the carrier, of an AM signal. A single-sideband signal, in this case the lower sideband, contains all of the modulation information of amplitude modulation in one half the bandwidth.

15)RF - Radio frequency.

16)RTTY - Radio Teletype communications.

17)Squelch - A user controlled adjustment which mutes the audio output below a certain signal strength.

18)Synchronous Detector - An amplitude modulation detector which utilizes a replica of the original transmit ted carrier signal to improve the reception of weak signals.

19)Synthesized - Capable of generating a large number of different output frequencies, all related to a single, highly stable reference source.

20)Up Conversion - A frequency conversion technique that translates an incoming RF signal to a higher fre quency.

21)USB - Upper Side Band - The higher frequency portion, excluding the carrier of an AM signal. A single sideband signal, in this case the upper sideband, contains all of the modulation information of amplitude modulation in one half the bandwidth.

22)UTC - Universal Time Coordinated.

23)VFO - Variable Frequency Oscillator.

24)VHF - Very High Frequency band extends from approximately 30 MHz to 300 MHz.
