The introduction of the all new AR7030 short-wave receiver is offered to the discerning and dedicated listener.
No matter how many new features are offered, ultimately a receiver will be judged on how well it receivers ! The AR7030 is the result of a combined project between AOR and a UK designer. The AR7030 represents the very latest and best design, featuring exceptionally strong signal handing and bristling with enhanced features. The AR7030 has been targeted to handle strong signals that are of prime concern to European listeners. It offers greater than +35dBm IP3(Intercept Point 3) and greater than 100 dBm dynamic range. The DMOS FET QUAD first mixer with NCO drive DDS offers the ultimate performance.

AR7030 ......

It is always nice to keep in contact but in particular this new bulletin has been issued to draw your attention to the AR7030 receiver which is now shipping with many options available and gaining awards and the respect of DX'ers as sales increase.

Time flies, already one year has passed since the launch of the AOR AR7030 short wave receiver. More than one reviewer commented that they have never known a new receiver create such interest and discussion, the internet being used in the early days to quickly propagate sales and technical information.

The AR7030 has received many favourable reviews by internationally recognised evaluation bodies, equipment reviewers and acknowledged top DX'ers, these include Passport to World Band Radio 1997, Monitoring Times, Radio Japan, Radio Netherlands, World Radio TV Handbook 1997, Alan Johnson USA, Guy Atkins USA / Canada, Nils Schiffhauer & Martin Elbe Germany, John Wilson SWM UK, Chris Lorek HRT UK, Peter Hart RadCom UK, Gordon Bennett AWR & many titles UK, Don Philips Danish DSWCI... the list goes on with independent test results published by many including Kiwa and the KZW30 team.

In particular the AR7030 has many pages dedicated to an in-depth review in Passport to World Band Radio 1997 where the receiver gained 5 out of 5 in the five star ratings. The World Radio TV Handbook 1997 too dedicated many pages to an in-depth review and awarded the AR7030 the ultimate accolade "Tabletop receiver of the year 1996/97". Extracts from both titles are included with this news bulletin.

Initially the AR7030 was warmly welcomed by dedicated short wave DX'ers hungry for the very best in performance and facilities, since those early days the customer base has widened considerably with the AR7030 selling to many "types" of short wave listener, not just to enthusiasts. This has led to great demands on manufacturing output which has been increased accordingly.

Of course the AR7030 is ready to operate straight out of the carton box but "operators" may wish to customise their receiver by adding options internally and externally.

Internal options:

MF500

Collins 500 Hz mechanical CW filter

CFJ455K8

1.0 kHz Murata ceramic data filter

XTAL2.4

2.4 kHz high quality 8 pole crystal filter
(daughter board recommended for fitting)

MF2.5

Collins 2.5 kHz mechanical SSB filter

CFK455J

3.0 kHz Murata ceramic very narrow AM / SSB filter

MF4

Collins 4.0 kHz mechanical narrow AM filter

CFK455I

4.0 kHz Murata ceramic narrow AM filter

MF6

Collins 6.0 kHz mechanical AM filter

FL124

Daughter board for fitting crystal filters

BP123

Internally mounted sealed lead-acid battery

FPU7030

Enhanced microprocessor as shipped with NB7030

NB7030

Enhanced multi-function audio notch and RF Noise Blanker PCB supplied with "enhanced features CPU" providing 400 memories alpha-tag text comments etc.

NB7030 Notch filter / noise blanker /replacement CPU

The NB7030 will be an all-in-one option comprising three facilities in one: NOISE BLANKER, NOTCH FILTER and FEATURES CPU with added facilities. This option will fit internally with excellent integration for the operator.

First part: Audio notch filter

Used to remove annoying whistles when listening in AM, SSB, Data and CW modes. A specially designed 4th order notch shape makes the notch "easy to tune" (unlike some other notch filters on the market) while retaining great depth. Excellent integration provides enhanced features such as notch follow and auto search for tone.

Audio notch filter
Tunable 200 Hz to 6 kHz
Auto search for tone
Auto fine tune / signal tracking
Notch follow when tuning (SSB modes)
Depth > 40dB 4th order notch (typ 50dB)
Width > 10 Hz at -40dB (@ 1 kHz)

< 100 Hz at -6dB (@ 1 kHz)

Second part: Impulse noise blanker

Useful for reducing ignition noise from passing motor vehicles etc. Switchable and adjustable threshold to ensure the highest performance is maintained. Unlike some other noise blankers, this option even works well in AM mode, not just SSB.

Impulse noise blanker
Switchable
Two available blanking periods
Operates in AM & SSB modes
15 kHz sensing bandwidth

Blanking periods
AM/SYNC 8mS / 12mS
SSB/CW 1.5mS / 12 mS

Third part: Enhanced CPU

Operators always want more... and YES, feature rich as it is already, it is possible to add even greater facilities to the AR7030. A replacement plug-in CPU with additional plug-in EEPROM will provide around 350 memory channels, each capable of retaining a 14 character alphanumeric text comment. When tuning across frequencies already stored in memory, the text display will be shown on the LCD for easy station identification. Multiple timers using data stored in memory allows multiple switch-on/off similar to a video recorder, ideal for unattended recording to tape. A frequency search facility is also planned plus slight changes to memory menus.

The enhanced CPU will be supplied as part of the NB7030 option but as a by-product will be available separately to those who desire the additional functionality without the noise blanker or notch filter. This is referred to as the FEATURES CPU, part number FPU7030.

CPU
Greater storage - plug in
400 memory channels
14 character alpha-tag per channel
auto text ident from memory while tuning
multiple programmable on/off timers
extra features
excellent integration

External options:

Data-Master -This full featured Windows95 PC package is now available from stock. As well as providing a text based control panel with drop-down menus, virtual receiver front ends are also provided: Digital... state of the art receiver with direct access to most facilities, Classic... if you have played with sets such as the Yaesu FRG7 then you will be at home, Portable... simple travel laptop appearance. It is possible to edit memory details, upload / download with save to disk, produce a spectrum display of band activity and more.

Geographical information may be projected onto a world map so that favourite stations may be "tuned" by one click of the mouse. Maximum / minimum (MUF) may be calculated from anywhere in the world and for any HF frequency then plotted onto a world map presented as polar or in horizontal format. An integrated database is also supplied so that frequencies may be managed & kept up-to-date, an integrated logbook is also provided. More? Yes, the list goes on with modulation / language hypertext files, propagation information etc. etc. Further information available to request.

TW7030 -This telescopic whip aerial (over one meter in length on a right-angle PL259) was specially produced for the AR7030 which has a built-in whip amplifier and impedance network fitted as standard to the receiver. Few telescopic whip aerials are available for short wave receivers in general with PL259 plugs for 50 OHM inputs, this makes the TW7030 an ideal companion for not only the AR7030 but many other brands too!

SM7030 -This service kit is now available. This kit comprises circuit diagrams, PCB layout, circuit description, PC service disk with hard copy instructions, technical bulletins on disk and RS232 lead.

Conclusion -Let us conclude this news bulletin by quoting two of the AR7030 reviewers:

Guy Atkins - DX ONTARIO: "I wouldn't be surprised to learn of cash-conscious organisations in industry and government choosing the AR7030 over other, more expensive commercial receivers for computer-controlled monitoring."

Larry Magne - MONITORING TIMES: "Viewed as a whole, the performance measurements of the '7030 suggest electrical performance that eclipses most of the radios currently regarded as top-gun receivers. And the ear confirms what the lab suggests..."

The short wave market has been quiet for a long time mainly due to lack of advancement in technology leading to short wave listeners becoming less enthusiastic about hardware. Now, the AR7030 has broken this spell by introducing fresh thinking and new technology.

Why don't you join us to share the world wide success of the AR7030.
