AR8000 operating manual 41 AM Amplitude Modulation - Used by broadcast services throughout the world on medium wave and shortwave. AM is also used by VHF Civil airband, UHF Military airband and some PMR (Private Mobile Radio) and utility services. NFM Narrow Band Frequency Modulation - this provides high quality communication for relatively short distance operation. FM uses a greater frequency bandwidth than other modes such as SSB so is less efficient. NFM is the most common mode used above 30 MHz...

AR8000 operating manual 42 Small tuning steps of 50 Hz or 100 Hz should be used for tuning in LSB and other similar modes USB & CW. The AR8000 being a hand held wide band receiver cannot offer the receive performance of a dedicated short wave receiver such as the AOR AR3030 or base wide band receiver AOR AR3000A. This is due to the limitation of size, as a result the receiver’s AGC (Automatic Gain Control) circuitry bandpass circuits and reference stability cannot be as complex. The AR8000 will however...

AR8000 operating manual 43 attenuator is OFF. The selection of attenuator may also be programmed into memory channels and when defining program search. Please refer to sections 4-5, 22 & 23 of this manual for further information regarding aerial suitability, and filters. 6-13 [B SCP] band scope operation A band scope facility has been provided so that adjacent channels can be monitored graphically for activity. The band scope may be operated in 1VFO or 2VFO mode but cannot be used while in scan mode,...

AR8000 operating manual 44 To deactivate the bandscope, repeat the key sequence [FUNC] [7] or press the [2VFO], [SRCH] or [SCAN] keys. (7) Memory banks & channels It is very convenient to store commonly used frequencies into a memory bank along with mode and attenuator status, this saves having to key the data in over and over again. Memory recall is very straightforward and quick when compared to retyping all data. Think of memory channels as pages in a notebook each of which is numbered to identify...

AR8000 operating manual 45 During the manufacture and testing of the receiver, various test frequencies are entered into the receiver’s memory banks so the memory locations are unlikely to be completely blank. Note: Where memory banks etc are empty the indication “- - -” is often displayed. 7-1 Storing receive data into memory - memory input in VFO mode Lets assume that you wish to store the frequency of 88.3 MHz with the attenuator Off into memory bank “A” location “00” (A00) while in VFO mode. Start by...

AR8000 operating manual 46 If you are happy with the alphanumeric description press [ENT] and the display will return to VFO mode. At any time you may abort the memory input by pressing the [CLEAR] key, the display will return to VFO mode. 7-2 Memory recall (M.R) - Recalling receive data from memory Once receive frequency and mode data has been stored into a memory location, its retrieval is quick and simple. Let’s assume that you wish to retrieve the frequency of 88.3 MHz which has been programmed into...

AR8000 operating manual 47 Note: If you have activated the PASSWORD protection, it is not possible to access memory banks a, b, c, d, e, f, g, h, i, j until the password has been keyed in each time the set has been switched On. Please refer to the PASSWORD section (9) of this manual for further information. 7-3 Transfer of memory channel to VFO Should you wish to tune away from the memory channel and benefit from not having to re-enter the frequency, mode, attenuator setting, channel step and step...

AR8000 operating manual 48 [9] [2] [.] [7] [ENT] to select the desired frequency, the mode and step size will be automatically set by the AR8000 microprocessor. Press and hold the [ENT] key for more than one second to enter memory input mode. Press [1A] [0] [0] [ENT] [ENT] to over-write the previous data. At any time you may abort the memory input by pressing the [CLEAR] key, the display will return to VFO mode. 8-2 SET EDIT-CH - editing, copying, moving and swapping memory channels Comprehensive memory...

AR8000 operating manual 49 “COPY-MODE” to indicate that a sub menu has been selected. The cursor will be positioned over the memory bank identifier (LETTER). Use the [DIAL] or keypad to select the memory channel which you would like to copy (like the original of a photo copier!). The third line will alternate between MODE and STEP while the fourth line will alternate between TXT and FREQUENCY so that easy identification of the desired memory channel may be made. Once you have chosen the desired memory...

AR8000 operating manual 50 8-4 MEMORY CHANNEL COPY - alternative method using memory recall Other AR8000 facilities may be manipulated in order to achieve data copying of memory channels. In particular memory recall and memory input may be used to copy frequency, mode and step data but not alphanumeric comment to another memory location. To carry out the same example as shown in section 8-3 (COPY-MODE) but copying the data of memory channel “A00” to “C23” proceed as follows: Press [SCAN] to access...
