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!

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.

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. 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). Scanning and search speed is a very respectable

maximum of 45 channels or increments per second using

“Cyber Scan”

technology. A DTMF decoder is provided

to display DTMF characters in use with an optional CTCSS board to display the CTCSS frequency. Extensive

facilities are available via the RS232 port, other useful facilities include a built-in dual time clock with On/Off timer.
