This instrument is an AOR AR5000 CyberScan 'the New Horizon' that is in very good, used condition. It saw some very light service from a local DoD defense contractor that had liquidated their laboratory assets. This receiver--along with other, very expensive test equipment of all kinds, was just one of the assets acquired. And like the test equipment, this instrument was pulled from a working environment, with just about everything on the pallet in exceptional condition. All pictures, including the first picture, are of the item you will receive.
TESTS PERFORMED: Complete panel switch test and panel light check. Radio circuit functionality check. CPU and Memory reset checks.
RESULTS: All tests performed as expected. Radio pulled in stations in both AM and FM modes (no other modes were checked). Front panel VU meter swings to the right when activity is heard from the speaker. Advanced modes were not checked, but assumed working. All LCD digital display parameters appear to work/display as intended. In short, the instrument appears to exhibit 100% functionality, both operationally and cosmetically (however, the torque adjustment lever that applies braking to the main dial functions normally, but does not apply enough torque to prevent the main dial from moving when high levels of turning torque is applied to the main dial. In other words, the torque lever applies some breaking the the main dial, but not a lot of breaking to the main dial. We are unsure if this is normal behavior or not).
This receiver does come with its Owner's Manual.
The receiver does not! come with its power adapter. Please use power from a fully-regulated DC power supply if the adapter is not present or accounted for...
This receiver will be shipped with its RF accessories.
Ok, now onto the (seemingly endless) features and benefits to the receiver:
"The experts have evaluated the AR5000 and have concluded that there is nothing in its class on today's market that comes close. The AR5000 has the competitive edge with wider frequency coverage, advanced circuit design, computer control of all functions, front end design, IF filtering, dynamic range, sensitivity, size & weight, power consumption and more. Following are more details of the AR5000 functions and features. And in addition, detailed specifications and a comparison of the AR5000 to the nearest competitor."
WIDER FREQUENCY COVERAGE
State of the art design using leading edge components enable the AR5000 to tune down to 10kHz and up to 2600MHz*. Imagine one small receiver tuning OMEGA navigation at 10-13kHz and instantly tuning to the 2.5GHz LEO satellite band.
All functions on the AR5000 are RS232 controllable. The AR5000 is a dream come true for those applications when remote and/or multi- receiver operation is desired.
CASCADE IF FILTERING
Two banks of filters are employed, one at 10.7MHz and the other at 455kHz. Selecting an IF bandwidth switches both IF amplifier filters and provides a superior overall shape factor which reduces unwanted signals and interference, and improves both dynamic range and image rejection. No other receiver offers such advanced filtering techniques.
MORE IF BAND WIDTH FILTERS
The AR5000 is supplied with 6 IF filter band widths (3,6,15,30,110, and 220kHz). A 7th position is open in the 455kHz for an optional 500Hz Collins CW filter. 30kHz is ideal for high speed data rates, 110 & 220kHz for higher data rates; 220kHz is also for FM SCA (sub-carrier) broadcasting and FM sound in both FM and T.V. audio channels. A 400kHz extra wideband FM filter and discriminator are under consideration. Supplied with a total of 12 IF filters, 6 in each IF.
FREQUENCY STABILITY (INTERNAL)
The AR5000 comes standard with a highly accurate TXCO internal frequency standard of 2ppm over a temp range of 0-50 degrees C (32-121 degreees F). Other receivers in this class specify accuracy, but fail to mention any temperature range.
An FM Wide & Narrow fixed level discriminator output is provided for multiplex (MUX) signal processing; FMW sub-carrier and Hi speed data rates are typical applications.
EXTERNAL FREQUENCY STANDARD
A first for a receiver in this price range. Using an external source has several advantages. (1) Note the AR5000 has 1Hz resolution. At 1000MHz, 1Hz is 1 part in 109, use of a standard at least good to 1 part in 109 will make that last digit have full meaning. (2) It is desirable to use one master oscillator when two or more receivers are used in a system. Accuracy and phase stability is assured. (3) Diversity reception is possible using external master OSC. Diversity has been used for years on long haul HF circuits and can also be used in VHF/UHF applications. (4) Direction finding: One method of DF is "time of arrival" (or phase) of the received signal using two receivers. Using on master OSC assures both receivers will be coherent and in phase.
DTMF (built-in): DTMF tones are usually heard while monitoring telephone calls. The AR5000 will decode and display these phone numbers. DTMF tones are sometimes used to remotely control systems and for other applications.
THIS UNIT MAY OR MAY NOT HAVE THESE OPTIONS:
(VOICE INVERSION DECODER UNIT DS8000 (plug-in option): Voice inversion provides a low level of "voice scrambling" and the DS8000 will decode the audio and make it intelligible to the listener.
CTCSS unit CT5000 (plug-in option): Sub-audible squelch tone can be decoded, displayed, and stored in memory. It is possible to place a CTCSS tone into memory and scan for that tone; the receiver will not stop on a signal unless that tone is present. On community repeaters, there may be several users each with their own CTCSS tone, one may wish to monitor just one user by opening the squelch only on that users' CTCSS tone.)
Hi pass filter 50, 200, 300, 400Hz; Low pass filter 3, 4, 6, 12kHz and thru position plus 4 time constants (25, 50, 75 and 750ms) are provided for FM de-emphasis. These features allow audio flexibility in all modes, previously not offered on a communications receiver.
compare the FM (narrow) sensitivity of the AR5000 with and you'll find the AR5000 unmatched, especially in the high end 1600 to 2600MHz.
PRE-SELECT FRONT END
A tracking front end pre-selector filter helpsreduce or eliminate interference from unwanted signals and increases sensitivity. This filter is auto-tracked from the CPU or can be manually tuned or RS232 controlled. Once the signal is peaked, the filter setting may be placed into memory for future use. Front end tracking filter tunes 0.5-1000MHz plus a high pass filter is used above 1000MHz and a low pass filter below 500kHz. Other receivers may offer preselect filters but no means of tuning or peaking a signal, thus reducing overall sensitivity specifications.
A low noise, high quality 10dB pre-amp is always ON below 230MHz and not used above 230MHz. The pre-amp combined with a 10dB attenuator provide a range of 20dB below 230MHz; the readout will indicate ATT 0, 10, 20dB. Above 230MHz readout is ATT 0, 10dB. These settings can be stored in each memory channel for future reference.
VOICE CONTROLLED SQUELCH
VCS is designed to eliminate the problem of scan-stop on an un-modulated carrier. Unless there is voice modulation present, the scan mode will continue past a signal. The VCS will also operate on modes other than FM(N), static crashes from thunder storms in the HF (2-30MHz) band often disrupt scanning. With VCS these false stops are greatly reduced.
One can scan memories, enter the desired dwell time, set AGC threshold level, voice squelch, for any memory and stop on carrier.
POWER ON/OFF VIA REMOTE
In remote applications, one may prefer not to have the receiver ON 100% of the time, to conserve power and/or reduce the possibility of detection. The AR5000 will accept a remote command to turn it ON or OFF.
Selectable in 100Hz steps from 400 to 1100Hz, the operator is able to tune CW and other digital signals to the correct frequency without changing the receiver's main tuning.
ACC1 FRONT PANEL JACK
This jack provides audio output/input return (for use with external signal processing units), discriminator output (switchable from wide to narrow FM), and audio output with switching control of tape recorder.
TWO TUNING CONTROLS
The main knob provides tuning steps from 1Hz to 1MHz and a mechanical variable torque adjustment ideal for fine tuning of CW, SSB and digital signals. The second knob has "click" indents ideal for channel tuning and has step sizes of 100Hz, 1kHz, 10kHz, 100kHz, 1Mhz and X10 for rapid tuning.
MANUAL/AUTOMATIC RF GAIN CONTROL
Reception of CW, SSB and digital signals can usually be improved using the manual gain control (MGC). Reducing RF gain can eliminate receiver noise allowing only the signal above the noise floor to be copied. Large signals from nearby transmitters may drive a receiver into distortion in the AGC mode, however MGC will allow low distortion reception of nearby transmitter and high power signals. The squelch control is also used as the RF gain control (push "FUNC" then 6 [RF Gain]).
DUAL ANTENNA INPUTS
Typical application is to use port (A) 30MHz down and (B) 30MHz up, since the antennas are usually very different. One can also use either antenna port at any frequency. If working on the VHF bands, port (A) could be a discone omni-directional antenna and (B) a gain antenna with directivity, or switch between an HF active antenna and a longwire antenna. Port selection may be stored in memory thus assuring the proper antenna for any given frequency.
4 PORT ANTENNA SELECTOR:AS5000
An optional external 4 port antenna switch box may be added to either antenna port providing a toatal of 5 antenna inputs. The possibility of using (2) AS5000 (one on each port) is under consideration. This would allow up to 8 antennas all switched from the front panel or remotely via RS232.
SPECTRAL DISPLAY READY (SDU)
IF output 10.7MHz with 10MHz bandwidth, to drive several models of SDU, is provided plus these added features: (A) AGC on/off is unique and standard in the AR5000. Receivers in which the AGC cannot be defeated will produce poor results on any SDU due to the AGC pumping action. When a strong signal is received, the AGC action causes a reduction in receiver gain and all signals displayed on the SDU screen are reduced until that signal is no longer in the receiver band pass. In a busy band, the AGC pumping action is very undesirable. (B) Pre and Post IF filtering: The user may switch the IF output to Pre or Post position of the 10.7MHz filtering, Pre filtering for wide sweeps and Post filtering for narrow sweeps, thus taking advantage of the filter to narrow the spectrum of interest. (C) The AR5000 CPU can be controlled by the SDU5000 keyboard. This digital linking of these two units allows signal monitoring never offered in an instrument of this class. In turn, the SDU5000 may be controlled by a PC computer thus producing a very powerful, low cost intercept system.
2100 Pass frequencies may be placed into storage. This allows the user to lock out up to 2100 frequencies not of interest. Pass frequencies do not use any memory channels. In most scanning receivers, one must place a frequency into memory and then write-in "pass". Each pass takes away another memory channel, but not in AR5000.
AUTO-MODE BAND PLAN
To aid the user in getting started, AOR has programmed 100 memory channels and 10 search banks. Each memory channel includes frequency, mode and alpha-numeric text to identify each station or band. Examples: (CH7)5.995MHz Mode(AM) "VOA", (CH11)17.765MHz Auto (AM) "Germany", (CH16)7.295MHz Auto(LSB) "40MTHAM", (CH45)203.75MHz Auto(FMW) "TVCH11". (CH72)467.875MHz Auto(FMN) "BUSINESS". 10 search banks are also pre-programmed. Example: search(2)88-108 (mode)auto (text)FM BCB, search(3) 118-136 (mode)auto (text)aircraft. At any time the pre-programmed memories may be re-programmed by the user.
Five (5) VFO's are available. The VFO indicator is in the lower right of the readout, VA, VB, VC, VD, VE. Each VFO has in memory: freq., step size, filter bandwidth, antenna port and attenuator and/or pre-amp. One can have VFO(A) set for 800kHz, 6kHz BW, AM Mode, 10kHz Step, Ant#1 and attenuator 10dB. VFO(B) could be 146MHz, 6kHz, FMN, Ant#2, Pre-amp ON, and so on.

Low power requirement: 13.8 VDC 1AMP (max audio) using an external AC power supply (included). Advantage: (A)No heavy power supply in portable or field use. (B)Most built-in AC supplies produce excessive heat which raises the receiver temperature causing component values to drift and heat stress, thus raising failure rates.
