1-2 TAKE CARE OF YOUR RECEIVER
There are no internal operator adjustments needed. In the unlikely event of service being required, please
contact us for technical assistance.
Do not use or leave the receiver in direct sunlight. It is best to avoid locations where excessive heat,
humidity, dust and vibrations are present. Always keep the AR5001D f ree from dust and moistur e. Use a
soft, dry cloth to gently wipe the external surfaces clean; never use abrasive cleaners or organic solvents
which may damage certain parts.
Treat the AR5001D with care; avoid spilling or leaking liquids into the receiver and the associated
power supply. Special care should be taken to avoid liquids from entering the area around the controls and
through the speaker grill or via the connection jacks.
The AR5001D is designed to operate from a good quality regulated DC power supply of 10.7 to
16.0 V, which should be capable of supplying 2 amps. Neve r connect the AR5001D directly to an
AC power outlet.
The polarity of the DC input jack is clearly marked; the chassis of the receiver is at negative ground.
SAFETY NOTICE – Alwa ys disconnect the power supply from the AC outlet or switch off
the main power switch on the rear panel when the receiver is not in use for a long period
of time. If used mobile, it should be noted that the AR5001D has NOT been manufactured
or tested to meet any specific mobile safety requirements. The AR5001D has no user
adjustable internal parts.
If using the AR5001D as a base station, the best short wave reception is usually achieved by
grounding your shortwave antenna with a separate external earth (or ground) rod. However, consider the
implications carefully if your AC building supply uses a Protective Multiple Earth (PME) system. If in doubt,
consult a qualified electrician. Never earth (ground) to a g as pipe! The AR5001D has two antenna
connectors. These are intended for connection to a 50 ohm (unbalanced) coaxial fed antenna such as a
discone, dipole, Yagi, etc .
When installing an antenna, avoid power cables. Ensure that you do not confuse the antenna and the
IF output connector as they are located close to each other.
7
Operating anomalies
Should the AR5001D appear to behave s trangely, normal operations may be easily achieved by
performing t he following steps:
1. Symptom: No control of the receiver.
Action: Turn off the power switch on the front panel. Leave it off for
ap proximately 10 seconds. Turn the power switch back on again.
Normal operation should be restored.
2. Symptom: The display freezes.
Action: Turn off the main power switch on the rear panel. Leave it off for
approximat ely 10 seconds. Turn the power switch back on a gain.
Normal operation should be restored.
Should the AR5001D still behave strangely, try a RESET as explained in chapter 9-13 .

Terminology
Search & Scan
If you have not used a wide band receiver before or is not familiar with the terminology used, it is very
important to understand the difference between SEARCH and SCAN modes.
SEARC H: The AR5001D provides several operations where transmissions
(active frequencies) may be automatically located by sweeping the receiver over
a wide frequency range, either from the currently displayed frequency traveling
upwards (or downwards) in a specified tuning increment (step) or by sweeping
over-and-over between two spec ified frequency limits. This process is known as
SEARC HING. As the name implies, this process can take a long time to find
transmissions due to their ‘often intermittent’ and brief nature. For this reas on, it
is best to slice large frequency ranges into smaller, more manageable pieces
8
where they may be intensely monitored.
When examining large frequency segments, it is common to find that 90% of the
frequencies are inactive and only a small number of the remaining constitute what
you really want. Searching still remains the best way to initially locate active and
interesting transmissions (in conjunction with a good frequency listing and band
plan).
SCAN: Once active transmissions have been identified (either by searching or by
using a good frequency guide), it is more efficient to store the data into memories
which can be rapidly and automatically monitored in succession, stopping when
activity is encountered. This is a much more efficient means of monitoring the
most wanted frequencies as you have targeted 100% o f what you most want to hear.
By contrast, searching is very inefficient for day-to-day monitoring.
Note: For the search & scan functions to operate properly, it is ver y important
to advance the squelch to cancel background noise. This is because the
AR5001D believes that it has found an active frequency when the squelch opens
and the “BUSY” indicator lights up. Advance the squelch control clockwise until
the background noise is just cancelled; this is known as the “threshold” position.
If the squelch control is advanced too far, weaker signals may be missed.
More details about the remarkable features of the AR5001D
High frequency (45.05 MHz) IF output
The AR5001D has a 45.05 MHz analog IF output with 15 MHz bandwidth. The input signal to the 45.05
MHz IF stage is directly sent to the A/D converter for digital processing. This IF output signal may be
suitable as an RF front end for radio signal analysis applications.
High Stability Frequency Standard
When an optional GPS unit is connected , the inte rnal reference oscillator (10 MHz) will be locked by the
GPS receiver, and the highest stability reference signal (0.01 ppm) will be obtained. This is ideal for
frequency coherent operation and DF (Direction Finding) applications.
DDS (Direct Digita l Synthesizer)
The AR5001D uses a high speed DDS for the 1st local oscillator. Unlike a stand ard PLL (Phased Locked
Loop) circuit for the local oscillator, the DDS enables very high speed scanning as it generates signals
instantaneously, controlled by the CPU (Micro Processor).
I/Q Digital Output (Optio nal)
9
The I/Q stands for In-Phase/Quadrature-Phase.
In the 45.05 MHz IF stage, I/Q output is available as an optional feature. The I/Q digital signal consists of
two (2) different digital signals with phases shifted 90 degrees. The I/Q output is provided through a
continuously is ochronous USB 2.0 stand ard interface. By using the I/Q digital output, the streamed data
can be stored on a PC hard disk for future signal analysis.
The I/Q dig ital output of the AR5001D has a wide dynamic range (without AGC processing) floating point
data format.
FFT (Fast Fourier Transform)
The AR5001D utilizes FFT (Fast Fourier Transform) technology for high speed spectrum scanning.
FFT enables refreshment of the spectrum display more than 10 times per second for a 10 MHz span
(at 500 Hz RBW). The AR5001D scans 10 MHz of bandwidth.
LAN (Local Area Network) connection
When an optional (external) LAN interface is connected, the AR5001D can be remotely controlled
through the internet.
Triple channel reception (Receive three frequencies simultaneously)
Any frequency below 25 MHz can be received independently, s eparate fr om a frequency above
25 MHz. The refore, two (2) separate frequencies can be received simultaneously. Furthermore, any
two (2) frequencies above 25 MHz (within a range of +/- 5 MHz from the receive frequency) can also
be selected and received simultaneously. Therefore, up to three (3) frequencies can be received at
the same time.

24
3-5-1-2 CHANGING FREQUENCY USING THE MAIN DIAL
In VFO mode, the active VFO frequency may be ‘tuned’ in using the main dial which is mounted on
the right side of the front panel. Rotate the dial ‘clockwise’ to increase frequency o r turn
'counterclockwise’ to decrease frequency.
3-5-1-3 CHANGING FREQUENCY USING [UP] KEY OR [DOWN] KEY
The [UP] and [DOWN] keys provide a convenient method to change the frequency.
The speed the receiver steps up or down depends on the step size which is set to default to auto.
In auto mode, step size, receiver mode etc. are taken from the factory pre-programmed band plan but
may be overridden at any time.
Press the [UP] key to tune the receiver upward in whic hever step size is se lected, use the [DOWN] key
to tune the receiver downward in frequency.
3-6 RECEIVE MODE
Due to the necessities of signal bandwidth, channel occupancy and transmission effic iency, different
receive modes are used by various services. The tuning step and receive mode are allocated by
departments of Governments following international discussions so they are not consistent throughout the
world. For this reason, it is necessary to change receive mode in order to monitor various transmissions.
For your convenience, receive mode and tuning step size have been pre-programmed into the AR5001D
auto mode band plan data at the factory to simplify the operations of the receiver, especially while you
familiarize yourself with the functions. If needed, the defaults may be manually overridden at anytime
so that you may select an alternative receive mode and tuning step on any frequency.
AM – Amplitude Modulation
Used by broadcas t services throughout the world on long wave, medium wave and short wave.
AM is also used by VHF airband, UHF military airband.
SAM – Synchronous AM
Helps to listen to SW (Shortwave) AM broadcast stations with fading signals.
FM – There are two common types of FM (Frequency Modulation):
NFM – Narrow Band Frequency Modulation
Provides high quality communication for relatively short distance operation.
FM uses a greater frequency bandwidth than other modes.
25
NFM is the most common mode used above 30 MHz with the exception of the airbands. NFM is
widely used on the VHF bands: VHF marine band, 2m amateur band, 70 cm amateur band, PMR
(Private Mobile Radio) and utilities.
In the absence of a signal, the background white noise may appear quite loud. For easier listening,
the squelch control should be rotated clockwise until the background noise disappears; this should
be carried out while no signal is present. The point at which the background noise is cancelled is
known as the threshold point. Do not advance the squelch control more than necessary or the
receiver will appear to be desensitized and weaker signals will be missed.
WFM – Wide Band Frequency Modulation
Used by VHF and UHF broadcast stations as excellent audio quality.
This is available due to the relatively wide frequency bandwidth employed.
Used only for local services such as VHF band stereo channels.
LSB – Lower Side Band / A form of SSB (Single Side Band).
Not intended for commercial use but is extensively used by Radio Amateurs on frequencies below 10
MHz. This assists in the separation of Commercial and Amateur users on traditionally shared bands and
prevents them from speaking to each other.
SSB is a very efficient method of transmission as the unwanted second sideband and carrier have
been removed. This allows the full transmitter power to be employed in carrying useful information
within the wanted sideband. As a result, greater dis tances are possible on SSB and a smaller
frequency bandwidth is required than with most other modes.
USB – Upper Side Band
The same comments apply as for LSB. By conventio n, Radio amateurs also use USB above 10 MHz.
ISB – Independent Side Band
Similar to SSB, however, 2 independent SSB signals are transmitted on the same frequency.
Decoded signals can be heard separately from the headphone jack on the front panel.
CW - Continuous Wave
Also referred as Carrier Wave or Morse Code.
Commonly used on the short wave bands by ra dio amateurs toward the lower end of each band
allocation. Some commercial use is still made by shipping etc although its use is being phased out due to
the introduction of automated stations.
26
AIQ – Analog IQ for DRM
New digital communication format for SW (Shortwave) broadcast.
Proper software and external hardware are required to decode DRM (not included).
3-6-1 AUTO MODE SELECTION
When in auto mode, the receive mode and tuning step size are automatically selected for you by the
AR5001D microprocessor.
To activate auto mode or reconfirm its selection while in VFO mode, press and hold the [MODE] key for
two seconds. “AUTO” will appears above the frequency portion of the LCD.
Note: Auto-mode is cancelled as soon as the receive mode, tuning step or oth er related data are
changed. Reme mber that auto-STEP and auto-MODE are linked, reselect AUTO MODE if either have
been adjusted and you require the auto band plan selection.
3-6-2 RECEIVE MODE SELECTION
Any receive mo de may be selected at any frequency within the receiver’s frequency coverage.
To access the receive mode menu, press the [MODE] key.
The following modes are available:
FM stereo, FM, NFM, SFM, WAM, AM, NAM, SAM, USB, LSB, CW, ISB, and AIQ.
Use the sub dial to select the desired mode. To accept the selection, press the [MHz] key.
3-7 CHANGING THE FREQUENCY STEP
The specification for channel oc cupancy, step (s eparation) and mode are decided by and allocated by the
Departments of Governments following international discussions.
The allocation of frequency bands are not the same all over the world and channel separation (step)
varies from band to band. As an example, the channel separation (step) for the MW (medium wave) band
27
in the U.S.A. is 10 k Hz, and is 9 kHz in Europe and J apan.
For above reasons, it is necessary to change the frequency step size according to the local band plan.
The AR5001D has been pre-programmed at the facto ry with all the band plan data (specific to each market
area) so that the AR5001D will automatically select the appropr iate ste p size and mode for the frequency
chosen. This greatly simplifies operation o f the receiver while you are familiarizing yourself with all the
functions.
The pre-programming of step size may be manually overridden so you may choose alternative settings
at will or when band plans are updated.
If you wish to change the default tuning frequency step, press the [STEP] key. The LCD will dis play the
current frequency step and the blinking “STEP” while waiting for the new parameter. Use the sub dial to
select the desired step.
To accept the displayed tuning step size, press the [MHz] key.
The tuning step size may also be programmed in 1 Hz (via the keypad) so that unusual step sizes other
than those stated are possible. The acceptable step siz e range is less than 1 MHz in 1 Hz steps.
3-8 IF BANDWIDTH
The IF bandwidth selects how SELECTIVE the receiver will be when monitoring signals off air. However,
it is not simply a case of using the narrowest filter at all times; particular modes require differing amounts
