AOR AR7030 - "Superior by Design"

For many years short wave receiver manufacturers throughout the world have pressed forward the frontiers of performance and design bringing a handful of notable advancements and setting new industry benchmarks for receiver specification. With the introduction of the AOR AR7030 short wave receiver, a new measure of performance, indeed a new benchmark was offered to the discerning and dedicated listener.

The AR7030 is the result of a combined project between AOR and internationally acclaimed UK designer John Thorpe. The AR7030 represents the very latest and best ever "JT" design concentrating on exceptional strong signal handling and bristling with enhanced features and facilities. The AR7030 is being manufactured by AOR MANUFACTURING LTD based at the new Belper locale in Derbyshire UK.

AOR supplied "advanced" technical specifications are now also available.

Technical excellence - top of the class.

No matter how many new features and facilities are offered, ultimately a receiver will be; judged on how well it receives ! It is for this reason that we can feel so confident of the receiver's success and notability.

In Europe, especially at night strong signal handling is of prime concern and this is where the AR7030 stands ahead of the field offenng an IP3 greater than +35dBm (preamp off - around +25dBm preamp on), dynamic range greater than 100dB in AM mode with a 7 kHz filter and greater than 105dB in SSB modes with a 2.2 kHz filter. This fantastic strong signal handling is aided by the innovative configuration of a lateral DMOS FET QUAD first mixer running at 15V, relay switching in the front end (not diodes) and the use of shielded inductors throughout the signal path.

All this and GREAT SENSITIVITY better than 0 5uV for 10dB S/N in AM mode and better than 0.3uV for 10dB S/N in SSB. Selectivity too is razor sharp offerring greater than 90dB @ 10kHz SSB and greater than 100dB @ 20kHz

No other receiver "in the class" nor indeed at considerably higher price can match the sheer performance excellence of the AR7030. Unless you perhaps consider the AR7030 PLUS !

High Tech

The receiver is built around a TCXO frequency standard which provides the reference for all circuitry ensuring the ultimate in stability and optimum alignment. Single loop DDS provides the clean local oscillator reference essential for low reciprocal mixing levels and seamless tuning in approximately 2.7Hz steps (no tuning "plops" - at regular intervals). The receiver is double conversion superheterodyne with intermediate frequencies of 45MHz and 455kHz.

The I.F filters are self-aligned by the receiver using advanced microprocessor control ensuring "spot on" alignment and symmetry of passband characterstics essential for serious ECSS listening. The main PCB will accept a number of different filters including Murata and Collins, all will be self-aligned ! The on-screen displayed filter bandwidth is not hard written into the microprocessor code but is actually "measured" by the receiver under microprocessor control permitting various displays such as 2.2kHz, 2.3kHz, 2.4kHz, 2.5kHz etc depending upon the particular filter fitted. In fact the remote facilities are so powerful that standard dealer service kit will contain a PC disk for alignment, testing and diagnosis.

Virtually every aspect of the AR7030 will be controllable with the standard REMOTE port, even the twin line outputs may be configured as hi/low etc. The tape recorder slave relay may be configured to operate from the built-in clock timer or from the squelch control. Mute input is also available in order to mute the AR7030 for use with transmitters.

All modes are fitted as standard: USB, LSB, CW, AM, Synchronous AM, NFM, DATA. The receive coverage is 0 - 32MHz the AR7030 has NOT been disabled below 150 or 30 kHz. The standard fitted I.F filters include: 2.2kHz, 4 5kHz, 7kH and 10kHz with two optional positions available for CW or other filters.

Enhanced features include pass band tuning +/- 5kHz, variable audio pitch tune on CW & data modes and a new "variable bandwidth synchronous detector" for AM listening to eliminate the effects of transmitter / receiver drift as well as reducing distortion with selective fading. The pass band tuning may be used in synchronous AM mode to select synchronous USB, LSB, DSB or anything in between.

A specially developed AGC release characterstic has been developed to ensure SSB quality never before heard. Noise spike compression has also been included to reduce the effects of noise pulses.

A built-in six level attenuator provides many levels of sensitivity +10dB, 0dB, -10dB, -20dB, -30dB nand -40dB. However when considering the excellent strong signal handling of the AR7030 this is going to be a control rarely required ! The rear case of the AR7030 has inputs for a wire aerial with ground connection, 50 OHM SO239 plus selection of a whip.

Audio output is of high quality and clear tone when using the built-in top mounted speaker. A 3.5mm external speaker socket is provided on the rear panel which mutes the intemal speaker, the amplifier provides more than 2 WATTS of audio; there are even treble and bass controls. A stereo 3.5mm front panel socket provides headphone output from another internal stereo amplifier and may drive mono or stereo headphones.

Infra-red and microprocessor control

A 48 character DOT MATRIX alphanumeric rear illuminated display enables a huge amount of detail to be displayed. Microprocessor facilities include on screen 70 segment S-meter, twin VFOs, frequency readout to 10Hz, 100 memories which hold frequency, mode, filter, passband shift or squelch status, memory scan facility, clock & timer, filter information, memory review, menus etc.

An assignable control enables you to place the functions YOU want at your fingertips these include a press button and a spin-wheel These controls may be assigned as follows

Button:	Filter select	Spin Wheel:	Passband shift
	VFO Select		Squelch
	Memory Recall		Tone (treble or Bass)
	AGC Speed		Memory channel select
	Scan Start/Stop		I.F.gain

It is also possible to save a few of your "favourite" receiver setups for later retrieval to save you having to continually change parameters when changing from broadcast to data to amateur band listening.

A full featured 32 button infra-red remote control is provided as standard and provides access to virtually all the facilities (except aerial switching) including: Tuning, volume, tone, numeric keypad, memory functions, pass band shift, filter selection.

Stylish strong cabinet

The AR7030 features a custom CNC machined solid aluminiun front panel with extruded aluminium shaped sides, metal top, bottom & rear panels. The front panel finish is brushed and anodised with the sides and other surfaces toned in a matching textured paint. Smooth curved lines, detailed front panel, custom domed top mounted speaker grille and ergonomically placed controls spell out the attention to detail of the robust, solid cabinet.

Options

The AR7030 cabinet is extremely compact so there is limited internal space for options. This internal space is considered to be in three sctions. Generally speaking each option (except for filters fitted directly to the main PCB of which two can be fitted without the need for the Daughter Board) takes one space, the battery however takes two spaces. With this in mind it is theoretically possible to fit the crystal daughter board, noth/noise blanker PCB and WFM option all at the same time....but then there is no room for the internal battery. If the battery option is fitted then only one other option may be fitted in addition. Operation will usually fall into two categories of "High Performance" or "Portability" so this should not cause too much of a problem.
