1 Introduction
1-1 Introduction
Thank you for purchasing the AR-ONE Ultra Wide Band Communications receiver.
The AR-ONE is designed using the very latest technology to ensure the highest levels
of
performance and reliability. To get the best possible results from your AR-ONE, we
strongly recommend you to read this manual and familiarize yourself with the receiver.
Although carefully designed, this receiver (like all receivers) suffers from a degree of
internal noises known as spurious emission. They are a product of the receiver’s
circuitry, and therefore, it does not represent a fault. Apparent faults may be due to
accidental misoperation of the receiver. If you believe there is a problem, carefully read
5
all of the manual before deciding to contact your dealer for advice.
It is acknowledged that sections of this manual are repetitive, this is to enable the
manual to be used as a reference book (you don’t have to read it all from cover to cover
in one go). Due to the international nature of the product, some graphics contain
Japanese characters.
Every effort has been made to make this manual correct and up to date. Due to
continuous development of the receiver. and by error or omission anomalies may be
found and this is acknowledged.
© This manual is protected by copyright AOR, LTD. 2003. No information contained in
this manual may be copied or transferred by any means without the prior written
consent

1-2 Take care of your radio
There are no internal operator adjustments. In the unlikely event of servicing being
required, please contact your dealer for technical assistance.
Do not use or leave the receiver in direct sunlight (especially the LCD). It is best to avoid
locations where excessive heat, humidity, dust and vibration are expected. Always
keep
the AR-ONE free from dust and moisture. Use a soft, dry cloth to gently wipe the set
clean, never use abrasive cleaners or organic solvents which may damage certain
parts.
Treat the AR-ONE with care, avoid spillage or leakage of liquids into the receiver and
associated power supply. Special care should be taken to avoid liquid entering around
the controls, through the speaker grille or via the connection jacks.
The AR-ONE is designed for operation from a good quality regulated DC supply of 12
to
14 V, which should be capable of supplying 1.5 amps. Never connect the AR-ONE
directly to the AC outlet.
The DC input jack is configured Center Positive, the chassis of the receiver is at
negative ground. Where provided (depending upon world market location), the power
supply is pre-wired and provides a nominal 12 V DC output with suitable connectors
being fitted as standard for the AC power input and connection to the AR-ONE.
SAFETY NOTICE – Always disconnect the power supply from the AC outlet when
not in use. If used mobile, it should be noted that the AR-ONE has NOT been
manufactured or tested to meet any specific mobile safety requirements.
The AR-ONE has no internally user adjustable parts.
If using the AR-ONE in a base station situation, the best short wave reception is usually
achieved by the fitting of a separate external earth rod, however, consider the
implications carefully if your AC building supply uses a Protective Multiple Earth (PME)
system. If in doubt consult an expert electrician. Never earth to a gas pipe!
The AR-ONE has a single N type antenna connector for all frequencies. This is intended
for connection to a 50 ohm (unbalanced) coaxial fed antenna such as a discone, dipole,
7
unipole, Yagi, etc. When sighting the antenna, avoid power cables. Ensure that you do
not confuse the antenna and other IF output connectors as they are closely located.
Operating anomalies
Should the AR-ONE appear to behave strangely, normal operation may be easily
achieved by resetting the microprocessor. Two scenarios may be encountered due to
power transients etc:
1. Symptom:
Action:
LCD remains on, no control of the keypad.
Remove any connection to external power and leave it for
approximately 30 seconds. Reconnect power and switch on again.
Normal operation should be restored but the last used frequency will be lost, the
AR-ONE will restore the last but one frequency to
display.
2. Symptom:
Action:
The AR-ONE fails to power up.
Try the suggestions given in (1) then hold the ESC key while
powering up the AR-ONE to ‘Soft reset’ the microprocessor.
1-3 Attention while operating
1. Certain key operation are acted upon when the key is RELEASED, not while it
is pressed. Allow time for the AR-ONE to register such actions before pressing
another key.
2. The keylock (LOCK) is intentionally made to be difficult to operate to prevent
accidental operation. To release keylock, the LOCK key has to be held for more
than one second, the key icon on the LCD confirms operation. The LOCK is
disabled during keying sequences (such as when entering frequencies).
3. If a key sequence is not completed, the microprocessor will automatically
abort
most operations after about 90 seconds of keypad inactivity.
4. Currently displayed VFO data is saved at power down (to increase speed of
operation and to reduce write cycles). For this reason, if the AR-ONE is powered
down using the PWR/VOL control or external power is removed, the last
displayed frequency will be lost and the frequency used prior to this will be
displayed when next powered up.
Terminology – Search & Scan
8
If you have not used a wide band receiver before or not familiar with the terminology used,
it
is very important to understand the difference between SEARCH and SCAN modes.
SEARCH: The AR-ONE 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 specified frequency limits. This process is known as
SEARCHING, as the little implies, it can take a long time to find transmissions due
to their ‘often intermittent’ and brief nature. For this reason it is best to slice large
frequency ranges into smaller, more manageable pieces where they may be
intensively studied.
When examining large frequency bands, it is common to find that 90% of
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 transmission 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 forms a much more efficient means of monitoring the
most wanted frequencies as you have targeted 100% what you most want to hear,
by contrast searching is very inefficient for say-to-day monitoring.
Note: It is very important that the squelch is advanced to cancel background
noise for the search & scan functions to operate. This is because the
AR-ONE believes that it has found an active frequency when the squelch
opens and “S” ‘squelch open’ icon is displayed to the left of the signal meter.
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.
No noise and no “S” icon displayed (with squelch advanced clockwise
9
passed threshold) = squelch closed.
Signal received or ‘noise’ emanating from speaker (squelch fully
counterclockwise, below threshold) with “S” icon displayed = squelch open.

terminated in a 9-pin male connector. The RS-232C parameters may be defined using the
CONFIG menu. Baud rates (transfer speed) set to either 4800 or 9600 bps. Since there are
two independent RS-232C port with the AR-ONE, it is possible to set an ‘address’ to
facilitate connection of up to 99 AR-ONE to a single PC.
The RS-232C parameters are as follows:
Baud Rate:
4800 or 9600 bps
De-limiter:
CR, LF
Data bit:
Stop bit:
Parity:
8 bit
2 bit
None

1-7 IF output and Spectrum Display Unit (SDU5500, SDU5600 )
The rear panel has a 10.7 MHz IF output designed to drive the optional SDU5500 or
SDU5600 Spectrum Display Unit. The SDU5500 or SDU5600 provides an excellent tool for
locating elusive transmission with a PEAK capability to ‘freeze’ the briefest of transmissions
for later measurement of frequency and level after the event.
(Note: The IF output frequency is selectable in the CONFIG menu. (10.7 MHz or 455KHz).
2 Getting started
2-1 Making the AR-ONE ready for operation
2-1-1 LCD (Liquid Crystal Display)
All relevant operational information is provided via the LCD. The LCD contrast is
adjustable.
16
2-1-2 Connect the antenna
For reception on the all bands, connect the antenna to the N connector on the rear panel of
the AR-ONE. An optional SA7000 Super Wideband Receiver is provided for this purpose.
A receive frequency range of the SA7000 is 30 KHz ~ 2000 MHz.
2-1-3 Connect power
Connect the power to the DC power jack on the rear panel of the AR-ONE. Use either a
supplied AC power adapter. Or a regulated DC power supply (12 ~ 14 V with capacity 2A)
may be used. Do not connect to a 24 V system.
Main Power Switch ___|
|___ DC Power Jack
2-2 Switching On for the first time
Set the squelch control to the ‘mid point’ . Turn the power switch on the rear panel of the
AR-ONE. This is a main power switch. The Green LED lit on the switch. Then rotate the
PWR/VOL control to the ‘mid point’, as you start to rotate the PWR/VOL control, a ‘click’ will
be heard as the power isolation switch contact switches on. Please be careful NOT to
switch
on any receiver with an earphone connected, there may be an audible click when the unit is
switched on or the volume may be accidentally set too high.
Power/VOL control
•
•
Squelch control
The AR-ONE will take approximately 1 - 2 seconds before the information appears on the
17
LCD. It is normal, for the microprocessor of the AR-ONE generates the ‘boot up data’
required to control the receiver.
2-3 Squelch Circuit
In normal use, NOISE SQUELCH is used. However, LEVEL SQUELCH can be selected for
search and scan operations. The LEVEL SQUELCH parameter causes the AR-ONE to
check the signal strength of active frequencies and to only stop when the signal strength is
above a preset level (which is programmable).
To select LEVEL SQUELCH, perform the following steps:
1.
Push the FUNC key.
2.
Push the “8” key.
3.
On the bottom of the LCD, a bar will be displayed. Using the SQL control,
adjust the desired signal level.
4.
Push the ENT key to confirm entry.
5.
Squelch will open only when the input signal strength is above this set level.
6.
To select NOISE SQUELCH, repeat above steps.
2-4 VFO selection
The AR-ONE has ten (10) VFOs being identified as “V-A” through “V-J” on the top left of
the
LCD. The term VFO historically means ‘Variable Frequency Oscillator’ and today refers
to
a tuneable data store which contains frequency, step, step-adjust, attenuator etc. Pushing
the VFO key each time will select the one VFO out of 10.
The AR-ONE has an
AUTOMODE setting, and therefore, in most cases a proper receive mode and frequency
18
step are automatically selected.
2-4-1 Tuning frequency
2-4-1-1 Entering a frequency using the numeric keypad
While in VFO mode, enter the required frequency using MHz format followed by the ENT
key.
Example of frequency entry of 80.8 MHz
Push the [8] key. Push the [0] key. Push the [.] key. Push the [8] key. Push the [ENT] key.
Example of frequency entry of 954 KHz (0.954 MHz)
Push the [.] key. Push the [9] key. Push the [5] key. Push the [4] key. Push the [ENT] key.
Aborting frequency input
If for some reason you do not wish to complete the frequency data input, push the ESC key
before completing the input sequence with the ENT key.
2-4-1-2 Changing frequency using the main tuning dial
While in VFO mode, the active VFO frequency may be ‘tuned’ in using the rotary main
tuning
dial which is mounted on the right side of the front panel. You may rotate the dial ‘clockwise’
to increase frequency or turn ‘counterclockwise’ to decrease frequency.
2-4-1-3 Changing frequency using UP arrow key or DOWN arrow key
The UP arrow key and DOWN arrow key provide a convenient method of frequency
change.
19
The speed at which the receiver steps up or down depends upon the STEP SIZE which is
default to AUTO. In AUTO the step size, receiver mode etc. is taken from the factory
pre-programmed band plan but may be overridden at any time.
Push the UP arrow key to tune the receiver upward in whichever step size is selected, use
the DOWN arrow key to tune the receiver downward in frequency.
2-5 Changing receive mode
Due to the necessities of signal bandwidth, channel occupancy and transmission efficiency.
Different receive modes are used by various services. In addition to this specification for
tuning step and receive mode are allocated by departments of Governments following
international discussions so 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 AR-ONE auto-mode band plan data at the factory to simplify operation of the receiver,
especially while you familiarize yourself with all functions. Should you wish, 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 broadcast services throughout the world on long wave,
medium wave and shortwave. AM is also used by VHF airband, UHF military airband and
some PMR (Private Mobile Radio) and utility services.
FM
There are two common types of FM (Frequency Modulation, these are:
NFM – Narrow Band Frequency Modulation – this provides high quality communication for
relatively short distance operation. FM uses a greater frequency bandwidth than other
modes such as SSM so is less efficient.
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.
20
In the absence of signal, the background white noise may appear quite loud. For ease of
listening, the squelch control should be rotated clockwise until he background noise just
disappears, this should be carried out while no signal is present. The point where the
background noise is cancelled is known as 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 is available due to the relatively wide frequency bandwidth
employed.
Used only for local services such as VHF band stereo (received as mono on the AR-ONE)
and UHF TV sound channels.
LSB – Lower Side Band – is form of SSB (Single Side Band). LSB tends not to be used
commercially but is extensively used by Radio Amateurs on frequencies below 10 MHz.
This assists 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 distances are possible
on
SSB and a smaller frequency bandwidth is required than most other modes.
USB – Upper Side Band – The same comments apply as for LSB. By convention, Radio
Amateurs also use USB above 10 MHz.
CW -
Continuous Wave – Often referred as Carrier Wave or Morse Code. Commonly
used
on the short wave bands by radio 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.
2-5-1 Auto-mode selection
21
When auto-mode is in operation, receive mode and tuning step size are automatically
selected for you by the AR-ONE microprocessor.
To activate auto-mode or reconfirm its selection while in VFO mode,
Push and hold the MODE key for more than 2 seconds.
The AUT icon appears on the top right portion of the LCD.
Note: Auto-mode is cancelled as soon as the receive mode, tuning step or other related
data
is changed. Remember that auto-STEP and auto-MODE are linked, reselect AUTO-MODE
if either have been adjusted and you require the auto bandplan selection.
2-5-2 Receive mode selection
Any receive mode may be selected at any frequency within the receiver’s frequency
coverage. To access the receive mode menu, push MODE, the following modes are
available: AUTO, WFM, NFM, USB, LSB, CW.
Use the main tuning dial or arrow key to
make selection. To accept the selection, push the ENT key.
2-6 Changing tuning STEP size
The specification for channel occupancy, step (separation) and mode are decided by and
allocated by departments of Governments following international discussions.
Not surprisingly 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 in the U.S.A. is 10 KHz while in Europe and Japan
they are 9 KHz.
22
For above reasons it is necessary to alter the STEP size according to local bandplan
conventions. The AR-ONE has been pre-programmed at the factory with all the bandplan
data (specific to each market area) so that the AR-ONE will automatically select the
appropriate step size and mode for the frequency chosen. This greatly simplifies operation
of the receiver while you are familiarizing yourself with all functions.
The pre-programming of step size may be manually over-ridden so you may choose
alternative settings at will or when band plan are updated.
Should you wish to change the default tuning step size, push the FUNC key and then push
the VFO key.
The third row of the LCD will display the current default size.
The bottom line of the LCD displays the icon “STEP SET” to indicate that the AR-ONE is
waiting you to change the step size.
Use the main tuning dial or arrow key to select the desired step size. To accept the
displayed
tuning step size, push the ENT key.
The tuning step size may also programmed in 1 Hz (via the keypad) so that unusual step
sizes other than stated are possible. The acceptable step size range is less than 1 MHz in
1
Hz steps.
2-7 IF Bandwidth
The IF bandwidth selects how SELECTIVE the receiver will be when monitoring signals off
23
air. However, it is not simply a case of using the narrowest filter at all times, particular
modes
require differing amounts of bandwidth in order to operate otherwise the receive system
simply will not produce intelligible sound.
Correct receive mode and IF bandwidth must always be selected for optimum reception. If
the bandwidth selection is too narrow, distortion or signal break-up may occur. If the
bandwidth selection is too wide, adjacent interference may be encountered.
For this reason, a selection of IF filter bandwidths are fitted as standard. Typical examples
of
receive mode and IF bandwidth are:
300 KHz
-- VHF FM broadcast (220 KHz may be also be used – mono only)
200 KHz
-- VHF FM broadcast (110 KHz may be also be used – mono only)
100 KHz or 30 KHz – Wireless mic, etc. (30 KHz for satellite FAX, too)
16 KHz – PMR, amateur band, etc. FM 6 KHz may also be used
8.5 KHz or 6 KHz – VHF/UHF airband, short wave broadcast, medium & long wave, PMR,
etc.
3 KHz – Short wave amateur band, short wave utility such as oceanic airband etc.
0.5 KHz – Morse code used by radio amateurs and some marine traffic on short wave
An appropriate IF filter is automatically selected when automode is engaged. However any
combination of IF filter and receive mode is possible in the manual mode. When you have
manually selected an IF filter bandwidth, automode will be disengaged, but the receive
mode, step size, etc will be retained until they are changed manually.
2-7-1 Manually selecting IF bandwidth
Push the FUNC key, and then push the MODE key.
Selecting a new bandwidth from the list of 300, 200, 100, 30, 16, 8.5, 6, 3, and 0.5 KHz by
rotating the main tuning dial or arrow key. To accept the new bandwidth selection, push the
ENT key.
24
2-8 AGC (Automatic Gain Control)
To change the AGC parameter setting, push the FUNC key and then push the ATT key.

main tuning dial or arrow key. To accept the new AGC parameter, push the ENT key.
When MANU is selected, a desired parameter can be entered between 0 ~ 255 in the
Configuration Menu.
2-9 ATTENUATOR
25
Activating attenuator reduces signal to the RF input stages of the AR-ONE to prevent
overloading due to connection to an external antenna or when the receiver is used in close
proximity to strong transmissions.
The AR-ONE has four settings for ATT (attenuator), 0 dB, 10dB, 20 dB, and AUTO.
To change the ATT parameter setting, push the ATT key.
Selecting a new ATT parameter from the list by rotating the main tuning dial or arrow key.
To
accept the new ATT parameter, push the ENT key.
When ATT is set to OFF, the ‘t0’ icon will display on the top right of the LCD,
When ATT is set to 10 dB, the ‘t1’ icon will display on top right of the LCD,
When ATT is set to 20 dB, the ‘t2’ icon will display on top right of the LCD.

Selecting a new AMP parameter from the list of ON, OFF, AUTO by rotating the main
tuning
dial or arrow key. To accept the new AMP parameter, push the ENT key.
2-11 OFFSET
This function enables receive frequency to be quickly SHIFTED by a predetermined values,
this makes it easy to track duplex-transmissions or check repeater inputs/outputs. Offset
frequencies may be factory pre-programmed into the auto-mode band plan data for some
world market areas. Frequency offset may also be programmed manually.
The locations for frequency offset storage are numbered 00 to 47 with 00 acting as OFF,
this
makes 47 locations available.
Frequency offset may be programmed into VFO, memory channel and search banks. It is
most convenient to set-up in VFO mode then save the data to specific memory channels
for quick recall at a later date. Frequency offset is primarily designed for memory channel
27
use, it may appear rather long winged to toggle on/off in VFO mode. However even when
programmed, frequency offset is in no way detrimental to normal operation.
The acceptable range of frequency offset is 0 MHz to 999.999 MHz, of course if the offset is
set to 0 MHz, the frequency will not change! Before the FREQUENCY OFFSET function
can
be used, it first needs to be configured (unless factory programmed for certain bands).
2-11-1 Using pre-programmed frequency offset data
To access the frequency offset set-up menu, push the FUNC key, and then push the .
(decimal) key.
The third line will display DUPLEX followed by the current offset channel number.
Use the main tuning dial or arrow keys to review the offset locations. The shift direction
can be changed by pushing the FUNC key. To accept the offset setting, push the ENT key.
2-11-2 Entering new frequency offset data
Assume that you are in VFO mode.
To access the frequency offset set-up menu, perform the following steps:
1. Push the FUNC key, and then push the . (decimal) key. The third line will display
DUPLEX followed by the current offset channel number.
Use the main tuning dial or arrow keys to review the offset locations.
2. Push down arrow key. The cursor will move down to the bottom line of the LCD.
3. Enter the desired offset in MHz format. The shift direction can be changed by pushing
the FUNC key.
28
4. To accept the offset setting, push the ENT key.
3
Memory channels & banks
It is convenient to store commonly used frequencies into a memory channel along with
mode etc, this saves having to key the data in over and over again. Memory read is very
straightforward and quick when compared to retyping all data.
3-1 Memory channel overview
Think of memory channels as pages in a notebook each of which is numbered to identify it.
Data may be written to each new page (memory channel) and each page may be
overwritten with new data, they can be used over and over again. The AR-ONE has 1,000
memory channels and a priority channel.
Each memory channel may hold:
z
z
z
z
z
z
One receive frequency
Receive mode
Tuning step
Frequency offset
Attenuator setting
Text comment of up to 12 characters
The alphanumeric comment may be used to ease identification at a later date and to
provide
text search function. The 1,000 memory channels are divided into 10 banks, each having
100 channels. The memory banks are identified by the first BANK number 0, 1, 2, 3, 4, 5,
6.
7, 8 and 9 and the individual channels are numbered from 00 to 99.
29
Examples are “000” for the first channel location in memory bank “0” and “099” for the last
memory channel in memory bank “0”.
“415” is the location: memory bank “4” channel “15”.
The data contents of memory and search banks are held in a EEPROM so that no backup
battery is required for memory retention.
The stored data may be quickly and easily recalled, changed or deleted using the memory
recall and delete functions.
Note: When the receiver is switched OFF, all VFO data will be automatically stored into
EEPROM memory storage.
3-2 Storing VFO frequencies & data into memory
The process to save a displayed VFO frequency to memory is as follows:
a) In VFO mode, select the required frequency, mode, attenuator etc
b) Push the FUNC key, and then push the ENT key to go to the memory write screen
c) Use the keypad, main tuning dial or arrow keys to select the desired memory location
(BANK and CHANNEL)
d) Add a text comment (optional) or delete an existing comment
e) Push the ENT key to exit the menu and save the data to the specified memory
location
Let’s assume that you are going to store the frequency of 123.500 MHz into memory bank
30
“3” location “25” (325) while in VFO mode with the text comment of
“AIRBAND”.
If a mistake is made during programming, push the ESC key to abort entry and return to

function ( a minimum of 2 characters are required for text search).
To erase the text comment, push the SET key twice.
Push the ENT key to complete.
31
3-3 Memory read “M.RD”
Once frequency and mode data has been stored into a memory location, its retrieval is
quick
and simple.
Let’s assume that you are going to retrieve the frequency of 123.500 MHz which has been
programmed into memory “325” during an earlier example in the preceding section of this
manual.
Push the FUNC key and the push the SCAN key to go into memory read mode, the
“M.RD”
icon appears on the top left of the LCD to confirm operation. The AR-ONE will monitor
whatever memory channel you enter memory read.
The AR-ONE will display memory channel, mode, text comment (if one was used). The
memory channel last used (for memory write or recall) will initially be displayed. If the
desired memory channel is not immediately displayed, it may be recalled by keying in the
required three digit location.
32
To recall memory channel “325”, push either the right arrow key or left arrow key to select
“3” as the memory bank. Rotate the main tuning dial or pushing either the up arrow key or

4 SCAN – scanning memory channels
The AR-ONE has a SCAN mode whereby the contents stored in the MEMORY
CHANNELS
ARE AUTOMATICALLY RECALLED AND MONITORED very quickly for activity –
scanned.
*** It is important that you do not confuse SCAN and SEARCH modes. ***
33
SEARCH mode (covered later in this manual) automatically TUNES THE RECEIVER
THROUGH ALL FREQUENCIES between two specified frequency limits looking for active
frequencies.
4-1 SCAN – outline introduction
During SCAN, the AR-ONE automatically recalls memory channel which contains data in
numeric order and monitors it looking for activity. When an ‘active’ memory channel is
located (when a signal is found and the squelch is open), the AR-ONE will temporarily stop
scanning.
4-2 Starting SCAN
Presuming that some memory channels are programmed with data, to start the scan
process will take one push of the SCAN key.
The icon “HYPER CAN” is displayed on the LCD to indicate that the SCAN process has
been started, a bank number will be also be displayed representing the current bank.
Ensure that the squelch is set to threshold point so that background noise is
cancelled and the squelch closes (otherwise scan will not operate).
When SCAN has been selected, only the currently displayed memory bank WHICH
CONTAINS DATA will be SCANNED, receive mode and frequency are unimportant. Any
memory channels which contain no data (empty) will be ignored (skipped).
4-3 Selecting a scan bank
The memory bank identifier (such as “3”) will be displayed on the middle right of the LCD.
If more than one memory channel is programmed into the current memory bank, and when
an ‘active’ channel has been located (busy, so the squelch opens), the scan process will
temporarily pause on the active channel, the memory location (such as “115”) will be
displayed along with any accompanying text (displayed underneath the memory location).
To select another memory bank for scanning, use the right arrow key or left arrow key.
If no data is available, the next bank with valid data will be recalled (empty memory banks
are skipped).
34
To exit from SCAN mode, push the VFO key.
4-4 Select scan
Select scan enables you to ‘tag’ memory channels to make a temporary list up to 50
channels in the same memory bank for scanning in a separate list called the SELECT
SCAN
LIST.
4-4-1 Adding select scan channels in memory read
In memory read mode, push the FUNC key, and then push the 1 key to toggle the select
scan tag on/off, the icon “SEL” confirms selection.
4-4-2 Starting / stopping select scan
To start select scan, you must first have at least two memory channels tagged for select
scan.
Push the FUNC key, and then push the 2 key to start select scan. The direction of scan can
be reversed using the main tuning dial knob.
35
To stop select scan, push the VFO key.

Search mode
In search mode, the AR-ONE is programmed to automatically tune between two specified
frequency limits looking for activity. Please refer to section 1-3 of this manual if you do not
fully understand the function of SEARCH.
5-1 Search type
The AR-ONE is equipped with PROGRAM SEARCH.
PROGRAM SEARCH = search between user preprogrammed limits
5-1-1 Program search overview
There are 40 program search banks (referred to simply as search banks) which can be
programmed with specific parameters:
36
z
z
z
z
LO (lower) start frequency
HI (upper) stop frequency
Receive mode (or set to AUTO MODE)
Text comment
The program search banks are identified by numbers (01 ~ 40). To help with identification,
each bank may be labeled with an alphanumeric text comment.
5-2 Staring program search
Presuming that data is already stored into a search bank …
Push the SRCH key to start the program search process.
The LCD icon “SRCH” will be displayed and as long as the squelch is closed, the search
process will start from the lower frequency limit and will progress toward the upper
frequency limit. When the program limit is reached, the search loops around and starts the
process again.
Note: If no search banks have been programmed, the search will not operate.
37
5-2-1 Reversing the direction of search
To reverse the direction of search, use the main tuning dial or the up arrow key or the down
arrow key. This is useful to enable you to search back over an interesting point of the
search
process.

(DELAY).
6-10 Configure DELAY (Scan delay and Search delay)
This parameter affects the time, the AR-ONE will remain on active frequency in scan mode
or search mode once the received signal has disappeared and the squelch has closed.
This
Is particularly useful for customizing how long the receiver will wait for a reply before
resuming scan or search. For example, when communications are passed back and forth
between a control tower / aircraft which may take a few seconds. The limits are OFF /
HOLD
and 0.1 to 0.9 seconds in 0.1 second increments. The default is 2.0 seconds.
To access the configuration menu, push the FUNC key and then push the 7 key.
Push the down arrow key to move the cursor to “DELAY” selection point.
55
Use the main tuning dial or the right arrow key or the left arrow key to select the desired
delay parameters.
2.0s
The AR-ONE will wait the specified time after the squelch closes before
resuming scan or search.
HOLD
The AR-ONE will stop indefinitely when an active frequency is located, this
is very useful when you don’t want to miss that once-in-a-lifetime
transmission!
OFF
The AR-ONE will resume scan or search instantaneously when the
squelch closes.
Push the ENT key to accept the data and return to a standard display.
Alternatively, push the ESC key to abort entry.
Or, push the down arrow key to move to the next item on the configuration menu (FREE).
6-11 Configure FREE (Scan free and Search free)
The scan free and search free parameter determines how long the AR-ONE will remain on
active frequency before resuming scan or search even though the frequency is still active.
This is useful if you wish to gain a snap shot of activity without the AR-ONE being tied to a
busy frequency for long periods of time (such as when monitoring active commercial
repeaters etc). Scan free and search free time saves you having to manually intervene to
force the scan or search process to resume and saves the need to lockout memory
channels or search frequencies using the PASS function. The limits are OFF and 0.1 to 9.9
seconds. The default setting is OFF.
To access the configuration menu, push the FUNC key and then push the 7 key.
Push the down arrow key to move the cursor to “FREE” selection point.

The audio high pass filter is useful for limiting the audio bass response (allowing higher
tones to pass) improving intelligibility in certain circumstances (such as low frequency
whistles on AM, SSB & CW).
58
There are four available pass frequencies:
50Hz, 200Hz, 300Hz, and 400Hz.

This is really only applicable to FM mode and affects the sharpness of recovered audio.
60
The FM transmission in different world areas have been different defaults for de-emphasis.
For example, a value of 759 is selected in Europe, the recovered audio will sound very
muffled.
The available range is as follows:
THRU, 25uS, 50uS, 75uS, and 750uS
The audio de-emphasis can be set to automode to select the proper setting automatically.
The default is AUTO.

Alternatively, push the ESC key to abort entry.
Or, push the down arrow key to move to the next item on the configuration menu
(PRIO-CH).
6-15 Configure PRIO-CH (Priority Channel)
The priority function enables you to carry on scanning, searching or monitoring while the
AR-ONE checks a selected frequency for activity (taken from one of the 1,000 memory
channels periodically).
The priority checking is accomplished by momentarily tuning the receive circuit to the
priority
frequency to see if it is active. If the activity is found, the AR-ONE will remain on the active
frequency until the signal disappears. If no activity is detected, the receiver returns to the
VFO frequency, scan channel or search bank from where it originated.
The priority function has a large number of applications and is particularly useful for
61
keeping
an eye on a distress frequency while scanning or searching another frequency band.
Note: Depending upon the frequency and mode stored as priority, an audible click may be
heard when the priority function is in operation. This is quite normal and is caused by the
internal switching of circuitry necessary to accomplish the frequency change (as two
frequencies cannot simultaneously be monitored).
6-15-1 Engaging Priority channel
Once engaged, the frequency is checked for activity periodically by the preset period that is
set by the configuration menu.
To engage the priority function, push the FUNC key and then push the 7 key.

The function enables you to tap the 2nd IF signal (10.7MHz) or the 3rd IF signal (455KHz)
from the BNC (marked as 10.7MHz) type connector on the rear panel. The 10.7MHz of the
2nd IF signal is to be used with an optional SDU5500 or SDU5600 spectrum display unit for
signal analysis. The bandwidth at 10.7 MHz is +/- 5 MHz from the center frequency (10
MHz total).

Computer control
Connect the AR-ONE to one of the serial port of a computer using an RS-232C cable
terminated in a 9-pin plug.
The RS-232C parameters may be defined using the OCNFIGURATION menu. Baud rates
(data transfer speed) may be set to 4800 or 9600 bps. It is also possible to set an ‘address’
to facilitate connection of up to 99 AR-ONE to a single port for custom operation, the
addresses may be set between the limits of 01 to 99 with 00 representing single radio
operation.
7-1 How to send an RS-232C command
Each command comprises of two upper case letters (header) along with operations as
required. All command use ASCII code which MUST BE IN UPPER CASE (except for the
up
arrow key, down arrow key, right arrow key, left arrow key and remote ID command (^A)
which are non-printable and use the control codes of ASCII). A terminal program running
on
a computer should be set to:
Baud rate:
4800 or 9600 bps (this should match the AR-ONE)
DATA BIT:
8
STOP BIT:
2
64
PARITY:
NONE
XFLOW:
ONE
A multiple command entry is only valid where specified. Where a multiple command entry is
allowed, each command MUST be separated with a space “h20” (HEX DECIMAL). Each
command is completed and a [CR] or [CR][LF]. Although there is no local echo, either [CR]
or specified response should come back from the receiver after confirming the correct
command. If no response has been gained after a short while, the receiver has failed to
receive the command properly. Send a [CR] then re-send the command. Should problem
persist, check your connections and try reducing the RS-232C baud rate.
