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

mixer
with

offers
the
ultimate

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.

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.

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.

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.

-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.
