AR5000, AR5000c, AR5000+3
high performance wide band all mode receiver 10 kHz - 2600 MHz
Since the release of the AR5000, professional monitors, top-end hobbyists, government departments
and armed forces throughout the world have been astonished how the seemingly impossible has been
achieved: unparalleled high performance, an amazingly flexible operating system, high build quality
featuring a metal cabinet - yet still remaining very compact and relatively light weight. There is little
competition for comparison, 'the rest of the pack' are significantly larger, heavier or many times more
expensive!

AR5000+3 awarded four starts by both the authoritative Passport To World Band Radio and World Radio & TV Handbook
True base receivers are few and far between, some have simply evolved
from the hand held equivalents with little tangible improvement in
performance or facilities over their smaller counterparts (or use switched
wide band converters) - the AR5000 is not like this! AOR have been
synonymous with pioneering receiver design from many years and this
tradition continues with the AR5000. A great advancement in wide band
front end design has been made, partly due to the introduction of automatic
electronic preselection between 500kHz - 999.999999MHz with low pass,
band pass and high pass filters for other bands. The preselection may be
“manually tracked” when monitoring spot frequencies to help reduce any
potential effects of interference caused by nearby monster transmitters,
this results in excellent strong signal handling yet maintains high sensitivity.
A TCXO forms the building block which is fitted as standard to ensure a
very high degree of stability, provision is made to feed the AR5000 from an
external 10 MHz reference signal should one be available (commercial
organisations etc). A Numeric Controlled Oscillator (NCO) provides
smooth tuning with steps right down to 1Hz. The receive circuitry is a
triple conversion superheterodyne with I.F.s’ of 622MHz, 10.7MHz & 455kHz.
Multiple switchable I.F. bandwidths are available in both the 10.7MHz and
455kHz I.F. stages: 3kHz, 6kHz, 15kHz, 30kHz, 110kHz & 220kHz with
provision for an optional 500Hz Collins mechanical filter, also a substitute
2.5kHz Collins mechanical SSB filter and Collins mechanical 5.5kHz narrow
AM filter option is available.
The AR5000 is housed in a stylish custom solid metal cabinet and is
powered from the supplied external 12V d.c. power unit but may be operated
from any regulated supply or battery capable of providing 12-16V @
1.5Amps. Aerial input is via a high quality N-TYPE connector with a second
SO239 connector which is switchable manually or automatically from the
front panel. A switchable preamplifier is employed (below 230 MHz) plus a
switchable 10dB attenuator, this may be configured as "auto" so that the
receiver selects the optimum setting automatically.
Not only is the RF performance outstanding, the microprocessor facilities
also point to the forward and innovative thinking which forms the core of the
success. There are 1,000 memory channels, 10 scan banks, 20 search
banks with auto-memory store and a total of 2100 PASS frequencies,
5 independent VFOs, alpha-tag memory & search banks, frequency offset,
step adjust and auto-mode tuning to name just a few.
The 1,000 memory channels (10 banks x 100 channels), 20 search banks
etc are stored by EEPROM so that no external supply, battery or capacitor
is required for data retention. In addition EEPROM BANK SWITCHING
means that all the memory channels, search banks, pass frequencies and
VFOs are PROVIDED TWICE (making a total of 2,000 memory channels,
40 search banks, 10 VFOs etc). This is an ideal situation when more than
one operator is to use the equipment, each have their own 'virtual' set.
Scanning and search speed is a very respectable maximum of 45 channels
or increments per second using “Cyber Scan” technology. A meaningful
& detailed auto-mode bandplan has been preprogrammed (specific to each
market area) so that operation is straight forward and quick. Should you
wish, auto-mode may be easily cancelled by selecting a different step size
or mode. A special Frequency Offset facility plus step adjust has been
provided to simplify DUPLEX frequency monitoring and for tracking unusual
band plans. A wide variety of search and scan types are available including
memory scan, select scan (your temporary favourite frequency notepad!),
mode scan, bank scan, pause scan, search bank link etc with channel edit
facilities for changing memory contents. The squelch too may be configured
for noise, signal level, audio level etc.
Audio low pass and high pass filters may be configured and are
switchable around the following frequencies: LPF 3kHz, 4kHz, 6kHz &
12kHz, HPF 0.05kHz, 0.2kHz, 0.3kHz & 0.4kHz. De-emphasis is also
selectable: THRU, 25uS, 50uS, 75uS & 750uS. A DTMF decoder is
provided to display DTMF characters in use with an optional CTCSS
board to display the CTCSS frequency.
A front panel accessory socket provides audio break-out / return for use
with external signal processing units, detector output and switching
control for tape recorders. The AR5000 has a switchable 10.7MHz I.F.
output ready to plug straight into the optional SDU5500 spectrum display
unit for “real time” band occupancy evaluation and measurements in both
frequency and dBm signal level, finding those elusive transmissions has
never been so easy. Extensive facilities are available via the RS232
port which is standard on the AR5000. Even the volume and squelch
controls may be remotely controlled. Output terminals are provided for
an external speaker, headphones & transmit mute. Provision has been
included for an optional built-in signalling unit, external aerial switching
unit plus CTCSS and other decoder options.
A large rear illuminated segmented liquid crystal display provides a
wealth of operating detail including frequency, mode, AGC, etc but also
displays up to 8 alpha-numeric text characters so that comments may
be entered to accompany memory channels & search banks to aid easy
identification and retrieval of data. Two tuning controls are provided:
the main knob provides tuning steps from 1Hz to 999.999kHz and has
mechanical variable torque adjustment ideal for fine tuning such as SSB
applications, the second is click-indented ideal for channel tuning and
provides switchable step sizes of 100Hz, 1kHz, 10kHz, 100kHz, 1MHz
and x10 for rapid tuning. An analogue S-meter provides easy to see
relative signal strengths. Other useful facilities include a built-in dual
time clock 12hr/24hr with On/Off timer, sleep and alarm, variable beep
tone... plus much, much more! The English language operating
manual comprises 77 A4 size pages with graphical key presses and
lavishly illustrated LCD representations, a booklet containing the RS232
protocol listing is also supplied.

When making critical measurements, the frequency coherence is very
important whether a single or multiple unit is employed. Just like optical
telescopes, the output from several receivers may be ADDED together to
provide greater performance, however their frequencies must be
absolutely coherent. This involves the use of a single reference for all
oscillators employed throughout the receiver. Several receivers may
then be connected to a single external frequency standard safe in the
knowledge that their outputs will be coherent.
The AR5000c now provides this commercially required capability.
The “C” version may be provided to order in either the standard AR5000
format or with two of the +3 additions of AFC and NB. If you are a
commercial operator with this application in mind, please request the
separate specification information for the AR5000c.
AR5000+3 - Sync AM, AFC, NB
The “+3” version offers even more with synchronous AM (upper side
band, lower side band and double side band with excellent lock range),
AFC (Automatic Frequency Control for accurately tracking moving
transmissions or unusual band plans) and Noise Blanker.
★★★★✩ AR5000+3 awarded four starts by both the authoritative
Passport To World Band Radio and World Radio & TV Handbook
Passport to World Band Radio’99.
“Front-end selectivity, image rejection, IF rejection, weak-signal
sensitivity, AGC threshold and frequency stability all superior”.
“Unlike virtually every other receiver we have tested over the past 21
years, the frequency readout is unfailingly accurate to the nearest
Hertz. This should make the AR5000+3 of exceptional interest to
broadcast engineers”.
World Radio TV Handbook’99.
Speaking of the AR5000+3 in conclusion... “Compared with the
ICOM ICR-8500 it offers considerably more features, better strongsignal handling, wider coverage and decidedly superior filters".
