9、ING MANUAL 2Introduction Thank you for purchasing the AOR AR7030 high dynamic range, short wave, all mode receiver. The AR7030 is designed using the very latest DDS (Direct Digital Synthesis) technology to ensure the highest levels of performance and reliability. A TCXO (Temperature Compensated Crys

10、tal Oscillator) is provided for high stability. To get the best possible results from your AR7030 we recommended that you carefully read this manual and familiarise yourself with the receiver. Many apparent faults are often due to accidental mis-operation of the receiver so, if you think there is a

11、problem, carefully read all of the manual before deciding to return the receiver for repair. Every effort has been made to make this manual correct and up to date. Due to continuous development of the receiver and by error or omission anomalies may be found and this is acknowledged. This manual is p

13、lied Mains power supply Infrared remote controller and batteries Operating manual 2-2 Overview - read THIS if nothing else The AR7030 receiver pushes forward the frontiers of performance and microprocessor operation. In order to get the very best out of the receiver you will need to carefully read t

14、hrough all the sections of this handbook, however there are a few points worth noting first:- a.The receiver has been designed to be compact and robust enough for transportable operation, and as such there are relatively few front panel controls. The infrared remote controller should be considered a

15、s an extension of the front panel, offering single button access to many primary functions. The receiver can be operated without the infrared controller but more button presses may be required to perform the same operation. The infrared control input is accepted by sensors on both the front and rear

16、 panels of the receiver. If you cannot reliably enter commands with the controller in close proximity to the front panel, move it to one side of the receiver and make sure that an object behind the receiver will provide a reflection into the rear sensor. The infrared controller is powered by two AAA

17、 size 1.5V batteries (supplied) which have to be fitted before it can be used. observe the polarity carefully. You cannot harm the receiver by pressing buttons, turning knobs or exploring the menu options - experiment without worry. Only by using the receiver will you become fully conversant with it

18、s operation. If you really mess up the settings, a LOAD DEFAULT facility has been included so that you can return the set to its out-of-box condition (except for frequency memory contents). Loading the defaults will ensure:- sensible filters are selected for each mode of reception, no PBS offset, no

19、 BFO offset for CW and DATA modes, maximum IF gain with AGC on, auto synchronous AM, auto RF attenuation, flat tone control settings, standard line output levels etc. To load the default settings, press (to return to the SETUP menu), rotate the spin-wheel one click anti- clockwise so that the legend

20、 Deflt Set is displayed, and then press the button. Loaded . is briefly displayed in place of the clock to confirm selection. Should the filters appear incorrectly aligned or non- symmetrical, please refer to FILTER CALIBRATION in section 6-2 and look through section 6-1. b.The receiver does not hav

21、e a standard format of display readout - it can be configured to display time or pass band shift or filter selection or treble / bass tone selection or VFO selection or AGC or memory configuration. whatever YOU choose. The spin-wheel and the button will retain their last assigned functions when the

22、button is pressed allowing a selected function to be changed whilst the S-meter is displayed. To return to the SETUP menu and CLOCK display, press . To display the S-meter and return to the root level of the menu system, press . You may tune the receiver, change the volume and reception mode or sele

23、ct fast tune whilst any menu is shown on the display because these front panel controls have only one dedicated function. These are fixed controls, and are indicated in this manual with white lettering on a black background, similar to the lettering on the front panel. Similarly the and buttons alwa

24、ys have a defined function. The other receiver controls, arranged beneath the display, are referred to as SOFT-KEYS, because their function varies according to the context of the selected menus. In these cases the control description is displayed on the receivers LCD and in this manual with black le

25、ttering on a grey background. When no menu is displayed on the LCD - when the S-meter is shown - then the underlying buttons select the menu indicated on the panel:- MEMORY, RF / IF or FILTER. c.Each mode can have, and will retain, a different filter bandwidth (chosen from those available), pass ban

26、d shift (PBS) setting, BFO setting and AGC speed. When adjusting any of these settings the values are changed only for the current mode selected. Squelch value for NFM mode is held separately from the value for all other modes. AR7030 OPERATING MANUAL PAGE 3 d.It is possible to save and load up to t

27、hree of your favourite receiver set-ups, one for casual listening, one for serious DXing, one for data communication or whatever you choose. Each mode can have your own choice of filter bandwidth, pass band offset, BFO setting and AGC speed, along with global settings of the tone controls, auto / ma

28、nual synchronous AM, auto / manual RF attenuator and line output levels. All these settings can be held in one of the SETUP MEMORIES, A, B or C. Using the setups can avoid having to recall many different menus, and provides a useful short cut to changing listening modes. The setup memories are acces

29、sed through the SETUP menu by turning the spin-wheel until the required memory (A, B or C) is selected along with the required function:- to setup the receiver with the settings held in the memory or to transfer the receivers settings into the memory. Press the button to actually load or save the se

30、tup. e.The AR7030 has two VFOs, A and B - (Active and Background). Each VFO holds settings of volume, tone, receive frequency, reception mode, filter bandwidth, PBS, BFO, RF attenuator, IF gain, AGC speed, squelch, scan delay time and scan mode. The contents of the VFOs can be exchanged using the bu

31、tton, only the active VFO can be tuned. Note: The background VFO data will be lost when power to the receiver is switched off. f.The 100 frequency memories store receiver frequency, reception mode, filter bandwidth, PBS offset and squelch level. BFO frequency is stored instead of squelch level for i

32、n CW and DATA modes. Once recalled, (into the active VFO) it is possible to tune away from the memory data or change mode at will - for this reason there is little point in storing the same frequency with different modes in different memories, even when DXing a broadcast where AM, USB, LSB or Snc mo

33、des might be needed. Memory contents are not modified by changing any receiver settings - they will only alter if the button is pressed. Any previous contents are then overwritten. g.The receivers display is split into several different areas. The current FREQUENCY and MODE are always visible, but o

34、ther information varies depending upon the operating condition and the menus selected.
