AOR have been synonymous with pioneering design of high quality wide band receivers for many years building on the strength of the AR2001, AR2002, AR3000 and AR3000A. The tradition continues and we are proud to announce the arrival the very latest receiver...the AR5000.

The new receiver is not based upon any specific earlier model but draws on the best points and combines this experience with the latest circuit design. The result of this clever RF design is a very sensitive receiver with excellent strong signal handling capabilities over a very wide receive range.

The AR5000 is housed in a newly designed solid metal cabinet and provides a very wide receive frequency coverage from 10kHz to 2600MHz, all mode reception FM, AM, USB, LSB & CW and MANY microprocessor facilities aimed toward professional monitoring and the dedicated listener.

AOR have also just announced details of the enhanced AR5000+3

Receive circuit details

The AR5000 features a NCO (Numeric Controlled Oscillator) providing tuning rates right down to 1Hz. A TCXO is fitted as standard and used in conjunction with the WWV signal reference to ensure a very high degree of stability.

The receive circuitry is based around a triple 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, 40kHz, 110kHz & 220kHz with provision for a 500Hz option.

This 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 covering other bands. This is a real achievement for a receiver ith such a wide frequency coverage and scan/search speeds of up to 50 channels per second.

The AR5000 offers excellent receive sensitivity across the range, typical figures:

10 - 20 MHz	0 56uV AM 6kHz filter 10dB S/N 0 25uV SSB 3kHz filter 10dB S/N 0.36uV FM 6kHz filter 12dB SINAD 0.40uV FM 15kHz filter 12dB SINAD
90 - 150 MHz	0.50uV AM 6kHz filter 10dB S/N 0.20uV SSB 3kHz filter 10dB S/N 0.25uV FM 6kHz filter 12dB SINAD 0.28uV FM 15kHz filter 12dB SINAD
400 - 700 MHz	0.56uV AM 6kHz filter 10dB S/N 0.23uV SSB 3kHz filter 10dB S/N 0.28uV FM 6kHz filter 12dB SINAD 0.32uV FM 15kHz filter 12dB SINAD

Aerial input is via high quality N-Type connector and secondary switchable SO239 connector. A switchable preamplifier is employed for the short wave bands.

Microprocessor control

To compliment such receive excellence, the microprocessor facilities are right up to date and full featured. There are a total of 1000 memory channels provided in 10 banks of 100 channels with a large EEPROM memory store. 10 search banks are provided with a total of 1100 PASS frequencies. Scanning and search speed is a very respectable maximum of 50 channels or increments per second. Auto-memory may be switched On/Off and a special Frequency Offset facility has been provided to simplify DUPLEX frequency monitoring.

A large rear illuminated segmented liquid crystal display provides a wide range of operating detail including frequency, mode, AGC, etc but also displays up to 7 alpha-numeric text characters so that comments may be entered to accompany memory channels & search banks to aid easy identification and retrieval of data.

An analogue S-meter provides easy to see relative signal strengths.

A wide variety of search and scan types are available including memory scan, select scan (your temporary favourite frequency notepad!), mode scan, bank scan, search bank link etc. The squelch too may be configured for noise, signal level, audio level, CTCSS.

A DTMF decoder is provided to display DTMF characters in use and CTCSS search to display the CTCSS frequency in use. 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 detailed microprocessor based auto mode bandplan has been programmed for the specific market area so that selection of receive mode, step size and I.F. bandwidth may be carried out automatically by the AR5000 making frequency change quick and searching meaningful. Of course the auto mode may be manually over-ridden at any time. Step adjust helps follow non-standard & unusual offsets on bands. The aerial selection may also been programmed for automatic fast change.

There are a total of FIVE VFOs provided so keeping track of a number of "hot" frequencies is very easy. There are two tuning knobs provided; the main knob provides tuning steps from 1Hz to 999.999kHz and has mechanical variable torque adjustment. The second knob provides step selection of 100Hz, 1 kHz, 10kHz, 100kHz, 1 MHz and x10 for rapid tuning.

Other useful facilities include a built-in clock On/Off timer alarm and variable beep tone.

Extensive remote control

Extensive facilities are available via the RS232 port which is standard on the AR5000. Even the volume and squelch controls may be remotely controlled. There is a good selection of software that supports the AR5000 with some detailed on our Software page.

Output terminals are provided for external speaker and detector for improved decoder compatibility. Provision has been included for an optional built-in signalling unit.

SDU5000 & SDU-5500 ready

The AR5000 is ready to plug straight into the optional SDU-5000 or SDU-5500 spectrum display unit for "real time'' band occupancy evaluation and measurements in both frequency and dBm signal level. The 10.7MHz I.F. output of the AR5000 has a suitable 10MHz bandwidth ideally matched to the SDU5000. (Note: a microprocessor upgrade may be necessary in some SDU5000's).
