17、ating manual 4 (3) Major features General The AR3030 offers the very latest technology through use of its DDS (Direct Digital Synthesizer). The legendary Collins 6kHz AM filter is fitted as standard to provide the highest levels of AM selectivity. High stability is accomplished by the standard fitti

18、ng of a TCXO (Temperature Compensated Crystal Oscillator). As the model name would suggest, the tunable coverage is 30kHz - 30 MHz (with 29.999995 MHz being the actual upper limit of tuning) using silky-smooth 5Hz steps. The AR3030 offers all mode operation as standard: AM, S.AM (double side band sy

19、nchronous), USB, LSB, CW, FAX & FM. All necessary information relating to frequency, filter setting etc is presented via a highly visible switchable backlit custom LCD. Mode selection is displayed via a series of LEDs. Although 5Hz tuning steps are available in all modes coupled to true automatic ca

20、rrier insertion in USB, LSB, FAX & CW, a separate BFO control is selectable in USB, LSB, FAX & CW to provide even greater flexibility producing a manual form of pass band tuning. While in any receive mode it is possible to increase the tuning steps from five Hz (display resolution 10Hz) to hundreds

21、of Hz and kHz by pressing the kHz key while in VFO mode. Selection of MHz tuning may also be accomplished in VFO mode by pressing the MHz key. The position of the underscore character “_” indicates selected tuning rate. A smooth action rotary tuning control with a finger-tip-hollow is provided to en

22、sure a high level of operating pleasure, convenience and versatility. Frequencies may be entered directly via the numeric keypad, great versatility is provided by careful attention to firmware programming. Frequencies may be entered as kHz i.e. 6 0 9 0 kHz, MHz i.e. 6 . 0 9 0 MHz or the “band” may b

23、e selected i.e. 4 9 mtr returns to the last frequency used on that band, probably no other receiver offers such convenience. All broadcast bands are recognised as well as region 1,2 & 3 Amateur bands. i.e. 80, 75, 49m etc. Twin VFOs retain all necessary information such as frequency, mode, I.F. band

24、width, audio filter, attenuator setting and tuning step size and BFO status On/Off. 100 memories also hold the full range of settings making transfer to and from memory straight forward and very convenient. Optional VHF converters Two optional VHF converters are planned: AM108.00000 MHz to 139.99999

25、 MHz FM140.00000 MHz to 169.99999 MHz AR3030 operating manual 5 One converter may be internally fitted to further extend the receive coverage of the receiver. A separate 50 OHM BNC aerial socket is fitted to the rear case of the AR3030 in order to simplify connection to a dedicated VHF aerial. SSB (

26、Single Side-Band) - who uses it? SSB is a general term given to two additional modes of operation USB for upper-side-band and LSB for lower-side-band. Generally speaking, SSB is used by long range services such as oceanic airband, ship to shore and Amateur band to increase the operational coverage o

27、f the radio transceivers. Most point-to-point services use USB including Amateur band. By convention, Radio Amateurs use LSB below 10MHz. True carrier insertion is used for USB, LSB and CW with a separate SSB highly selective filter being used for these modes. A BFO control (which operates in CW, US

28、B, LSB & FAX modes) has also been provided so that the CW note may be optimised to suit individual preferences and to form a simple manual form of passband tuning, particularly helpful on a crowded frequency. The inclusion of SSB on the AR3030 adds a new dimension to the listening potential of the r

29、eceiver when compared to AM broadcast-only shortwave receivers. All Mode As well as SSB, the AR3030 can receive all other popular modes: AM (Amplitude Modulation) used mainly by broadcast stations and some other services (such as VHF commercial airband with the optional VHF converter fitted). Synchr

30、onous AM (double side band) used to combat fading on the shortwave bands. NFM (Narrow band Frequency Modulation) little used on the shortwave bands but found on the UK CB radio and 10m Amateur Bands. Bandwidth and filters The AR3030 is fitted with several standard IF bandwidths including a cascade 8

31、kHz/-6dB ceramic filter (CFU455G2) for AM/SSB/FAX/CW plus two audio bandwidths: AM/S.AM 6kHz/-3dB in the normal position using the legendary Collins eight resonator mechanical filter (526 8636 010) and a 2.4kHz/-6dB Murata ceramic filter (CFJ455K6) in the narrow position. Should the narrow CW option

32、al PCB position not be used, it is possible to fit an additional wider filter for AM such as Collins 8.5kHz/-3dB 526 8561 020. Due to the I.F. cascade filter, the widest possible filter is 8.5kHz. USB/LSB/FAX 2.4kHz Murata ceramic filter (CFJ455K6). An optional 2.5kHz/-3dB Collins eight resonator me

33、chanical filter (526 8635 010) of higher specification may be AR3030 operating manual 6 optionally fitted (workshop fitting) to replace the 2.4kHz filter. Should the narrow CW optional PCB position not be used, it is possible to fit the optional Collins 2.5kHz filter as an addition which will be sel

34、ected in the narrow position. CW 2.4kHz Murata ceramic filter in the Normal position. An optional 500Hz/-3dB Collins seven resonator mechanical filter (526 8634 010) may be optionally fitted (workshop fitting)in the Narrow position. FM 15kHz Murata ceramic filter (CFU455E2) fixed. Selection of Norma

35、l/Narrow is disabled. Attenuator, whip amplifier and aerial input & AGC The AR3030 does not contain RF amplification prior to the band-pass filters, all gain is applied in the more selective IF stages. This ensures the highest immunity to intermodulation effects often caused by the high number of st

36、rong signals encountered on the shortwave bands. There are two aerial inputs. The first is of the standard BNC type allowing straight forward connection to almost any low impedance shortwave dipole or multiband aerial system. The second is a “jaw” designed for a high impedance long wire. An earth co

37、nnection is also provided on the rear panel. A rear panel three position slide switch selects the 50 OHM BNC connector or high impedance wire input. The third position applies a preamplifier and impedance matching network to the BNC aerial socket which may be used in conjunction with a telescopic wh

38、ip aerial to enable a fair level of operation away from a long wire aerial or more elaborate system. An aerial attenuator system allows selection of 0db, 10dB or 20dB from the front panel. RF gain is also available via a front panel rotary control, this is especially useful in providing optimum audi

39、o quality for SSB operation. AGC attack / decay may also be selected from the front panel either fast or slow but cannot be switched off. Memories & SCAN There are 100 memory channels which can store frequency, mode, AGC, attenuator, bandwidth, AF filter (tone), BFO and lockout status. The memories

40、may be used to store shortwave or VHF frequencies if the VHF converter option has been fitted. Program scan allows only a selected block of channels to be scanned while lockout permits certain channels to be skipped. Pause and delay scan add to flexibility. Data may be easily entered into memory and

41、 back to VFO where it may be tuned. AR3030 operating manual 7 There is a massive EEPROM store for all memory channels and VFO data so that no memory backup battery is required. The memories may be over- written time and time again. RS232 computer port A 9 pin D type socket is fitted to the rear case

42、, this will permitcontrol of many receiver facilities via a computer. Loudspeaker and audio output The AR3030 has a built-in 66mm 3 WATT loudspeaker. A 3.5mm jack socket is located on the rear panel of the receiver for external speaker connection. Connection to this socket automatically cancels audi

43、o from the internal speaker. Audio output is also available through a quarter inch headphone jack plug located on the front panel of the receiver. Use of this headphone socket automatically cancels output from both the internal and external loudspeaker if used. A low level audio output suitable for

44、tape recording is available through via the AUX socket located on the rear panel. Switching to control a tape motor is also available via the AUX socket. A second constant level slightly higher output is available via a second rear panel 3.5mm socket suitable for connection to a facsimile decoder. A

45、GC and IF outputs are also available via an 8 pin DIN socket located on the rear panel. Versatility & power connection The AR3030 can meet a number of requirements to satisfy Broadcast, Amateur band, Airband or Marine enthusiasts, Professional off air monitoring and of course casual listening too. T

46、he Worlds shortwave and Amateur bands can be monitored, even the longer range Oceanic Airband and ship to shore. The receiver is designed to operate from either an external DC supply (such as that provided) of a nominal 13.8V DC or from internally fitted batteries (8 x AA dry cells which may not hav

47、e been provided). Although rechargeable batteries may be used with the receiver, they must be externally recharged. The receiver must never be connected directly to the mains supply. (4) Precautions AR3030 operating manual 8 4-1Location Do not use or leave the receiver in direct sunlight. It is best

48、 to avoid locations where excessive heat, humidity, dust and vibration are expected. Always treat the receiver with care. Take care to avoid spillage or leakage of liquids into the receiver and AC power supply. Special care should be taken to avoid liquid entering via the power jack. Always remove b

49、atteries if the receiver is not going to be used for a while. Avoid static discharge from wire aerials, earth to a central heating radiator or similar in order to discharge the wire before connection to the AR3030. Always disconnect and earth an aerial system if an electrical storm is expected. Avoid connecting / disconnecting the power connection or batteries with the set switched on. Avoid a rapid switch On/Off seque
