1 Introduction

1-1 Introduction

Thank you for purchasing t he AR-ONE Ultra Wide Band Communicat ions receiver . The AR-ONE is designed using the very latest technology to ensure the highest levels of performance and reliabil it y. To get the best possible results from your AR-ONE, w e strongly recommend you to read this manual and familiarize yourself with t he receiver. Although carefully designed, this receiver (like all receivers) suffers from a degree of internal noises known as spuri ous 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 t he receiver. If you believe there is a problem, carefully read

all of the manual before d eciding to contact your dealer for advice.

It is acknowledged that sect ions 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 cov er t o cover in one go). Due to the internat ional 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 developme nt of t he receiver. and by error or omission anomalies may be found and this is acknowl edged.

© This manual is prote ct ed by copyright AOR, LTD. 2003. No information cont ained in this manual may be copied or transferred by any means without the prior written consent of AOR, LTD. AOR and the AOR logo are trademarks of AOR, LTD. All other trademarks and names are acknowledged.

1-2 Take care of your radio

There are no internal operator adjustments. In the unlikely event of servicing being required, please contact y our 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 lea kage 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 capabl e of supplying 1.5 amps. Never connect the AR-ONE directly to the AC outlet.

The DC input jack is conf i gured Center Positive, the chassis of the rece iver is at

negative ground. Where p r ovided (depending upon world market location), the power

supply is pre-wired and prov ides a nominal 12 V DC output with suitabl e connectors

being fitted as standard for the AC power input and connection to t he A R-O N E.

SAFETY NOTICE – Always disconnect the power supply from the AC outlet when not in use. If used m obi le, it should be noted th at the AR-ONE has NOT been manufactured or tested to meet any speci fi c mobile safety requirements. The AR-ONE has no internally user adjustable parts.

If using the AR-ONE in a base st at ion 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 supp ly uses a Protective Multiple E a rth (PME) system. If in doubt consult an expert electrician. Never earth to a gas pipe! The AR-ONE has a single N t ype antenna connector for all frequen cies. This is intended for connection to a 50 ohm (unbalanced) coaxial fed antenna such as a discone, dipole,

unipole, Yagi, etc. When sighting the antenna, avoid pow er cables. Ensure that you do not confuse the antenna and ot her I F out put connectors as they are closely locat ed.

Operating anomalies

Should the AR-ONE appe ar t o behave strangely, normal operation may be ea sily achieved by resetting the microprocessor. Two scenarios may be encountered due to power transients etc:

1. Symptom: LCD remains on, no control of the keypad.

Action: 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: The AR-ONE fails to power up.

Action: 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 w hi le it is pressed. Allow time for t he 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, t he 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 seque nces (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 dat a is saved at power down (to increase speed o f

operation and to reduce writ e cycles). For this reason, if the AR-ON E is powered down using the PWR/VOL control or external power is removed, t he last displayed frequency w ill be lost and the frequency used prior to this will be displayed when next powered up.

Terminology – Search & Scan

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 receiv er over a wide frequency range, either fr om the currently displayed frequency t r aveling upwards (or downwards) in a specified tuning increment (step) or by sweeping over-and-over between two specif ied frequency limits. This proces s is known as SEARCHING, as t he 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 small er, more manageable pieces where they may be intensively studied. When examining large frequency bands, it is common to find t hat 90% of frequencies are inactive and only a small number of t he rema ining 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 tr ansmission have been identified (either by searching or by using a good frequency guide), it is more efficient to store the dat a int o memories which can be rapidly and automatically monitored in succession stopping whe n activity is encountered. Th is f orms a much more efficient means of mon it ori ng the most wanted frequencies as you have targeted 100% what you most want t o hear, by contrast searching is very inefficient for say-to-day monitoring.

: It is very important that the squelch is advanced to cancel background

Note

noise for the search & scan fu nctions to operate. This is because the

AR-ONE believes that it has found a n active frequency when the squelch opens and “S” ‘squel ch open’ icon is displayed to the left of the signal meter. Advance the squelch control clockwise until the backgr ound 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

passed threshold) = squelch cl osed.

Signal received or ‘noise’ emanating from speaker (squelch fully counterclockwise, below thresho ld) with “ S” icon displayed = squelch open.

2-4-1 Tuning frequency 2-4-1-1 Entering a frequency usi ng 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 frequ ency input

If for some reason you do not wish to co mp let e t he frequency data input, push t he ESC key before completing the input sequence with the ENT key.

2-4-1-2 Changing fr equency 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 t urn ‘counterclockwise’ to decrease frequ ency.

2-4-1-3 Changing fr equency using UP arrow key or DOWN arrow key

The UP arrow key and DOWN arrow key provide a convenient method of frequency change.

The speed at which the receiv er st eps 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 ov erridden at any time.

Push the UP arrow key to tune the receiver upward in whichever step size is selected, use the DOWN arrow key t o t une t he 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. I n addit ion to this specification for tuning step and receive mode are allocated by departments of Govern ments following international discuss ions so are not consistent throughout t he w orl d. For this reason, it is necessary to change receiv e mode in order t o monitor various transmissions.

For your convenience, receive mode and tuning step size have been pre-prog rammed i nto the AR-ONE auto-mode b and plan data at the factory to simplify operat ion 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 alternat ive receive mode and tuning step on any frequency.

Amplitude Modulation – U sed by broadcast services throughout the world on long wave, medium wave and shortwave. AM is also used by VHF airband, UHF mi litary airband and some PMR (Private Mobil e Radio) and utility services.

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 VH F bands: VHF marine band, 2m amateur ba nd, 70 cm amateur band, PMR (Priv at e Mobi le Radio) and utilities.

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 t ends not to be used commercially but is extensively used by Radio Amateurs on frequencies below 10 MHz. This assists the separatio n of Commercial and Amateur users on trad it ionally 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 allow s t he f ull transmitter power to be employed in c arrying 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 a mateurs toward the lower end of each band all ocation. 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

When auto-mode is in operation, receive mode and tuning step s iz e are automatically selected for you by the AR-ON E microprocessor .

To activate auto-mode or reconfirm its selection w hi l e 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 th at aut o-STEP and auto-MODE are linked, reselect AUTO-MODE if either have been adjust ed and you require the auto bandplan select ion.

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: AUT O , 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 G overnments following internat ional discussions.

Not surprisingly the allo cation of frequency bands are not the same all over the world and channel separation (st ep) 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.

For above reasons it is necessary t o alt er the STEP size according to local bandplan conventions. The AR-ON E has been pre-programmed at the factory w ith al l the bandplan data (specific to each market area) so that the AR-ONE will automatically select the appropriate step size and mo de f or t he frequency chosen. This greatly si mp li f ies operation of the receiver while y ou are familiarizing yourself with all functions.

The pre-programming of step size may be manually over-ridden so you may choose alternative settings at wi ll or when band plan are updated.

Should you wish to chang e t he def ault tuning step size, push the FUNC key and then push the VFO key. The third row of the LC D will display the current default size.

The bottom line of the LC D 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 select s 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 differin g amounts of bandwidth in order to operate otherw ise the receive system simply will not produce intelligible sound.

Correct receive mode and I F bandw i dt h must always be selected for optimu m recept ion. If the bandwidth selection is too narrow, distortion or signal break-up may occur. If the bandwidth selection is t oo 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 bandw idth 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 a irband, short wave broadcast, medium & long w ave, PMR,

etc.

3 KHz – Short wave amateur band, short wave utility such as ocea nic airband etc.

0.5 KHz – Morse code used by radio amateurs and some marine traf fi c on short wave

An appropriate IF filter is aut omatically selected when auto mo de i s engaged. However any combination of IF filter a nd receive mode is possible in the manual mode. When you have manually selecte d an I F f il ter bandwidth, automode will be disengaged, but the receive mode, step size, et c w ill be retained until they are chang ed manually.

2-7-1 Manually selecting I F 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 di al or arrow key . To accept the new bandwidth selection, push the ENT key.

2-11 OFFSET

This function enables rec eive frequency to be quickly SHI FTED by a predetermined values, this makes it easy to track dupl ex-t ransmissions or check repeater inputs/out puts. Offset frequencies may be factory pre-programmed into the auto-mode band pl an data for some world market areas. Frequ ency offset may also be programme d manually.

The locations for frequency offset storage are numbered 00 to 47 with 00 acting as OFF, this makes 47 locations av ailable.

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 me mor y channels for quick recall at a later date. Frequency offset is primarily designed for memory channel

use, it may appear rather long winged to t oggle on/off in VFO mode. H ow ever 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 of fset 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).

3 Memory channels & banks

It is convenient to store commonly used frequencies into a memory cha nnel along with mode etc, this saves havi ng t o key the data in over and over again. Memory read is v ery straightforward and quic k w hen 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 ea ch new page (memory channel) and each page may be overwritten with new data, they can be used over and over again. The AR-O N E has 1,000 memory channels and a priority channel.

Each memory channel may hold:

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 me mory 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,

7, 8 and 9 and the individual ch annels are numbered from 00 to 99.

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” chann el “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 quic kly and easily recalled, changed or deleted using the memory recall and delete functions.

Note:

When the receiver is switched O FF, all VFO data will be automatically st ored int o

EEPROM memory storage

*** It is important that you do not confuse SCAN and SEARCH modes. ***

SEARCH mode (covere d l ater in this manual) automatically TUNES THE RECEIVER THROUGH ALL FREQUENCIES between two specifie d frequency limits looking for active

frequencies.

4-1 SCAN – outline introduction

During SCAN, the AR-ON E aut omatically recalls memory chan nel 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 w i ll t emporarily stop scanning.

4-2 Starting SCAN

Presuming that some memory chan nels 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 a lso b e displayed representing the current bank.

Ensure that the squ el c h is set to threshold point so t hat 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 unimport ant . Any memory channels which cont ai n no dat a (empty) will be ignored (skipped).

4-3 Selecting a scan bank

The memory bank identifier (such as “3”) w il l be d isplayed on the middle right of the LCD.

If more than one memory channel is pro grammed into the current memory bank, and when an ‘active’ channel ha s 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 underneat h t he memory location).

To select another memory bank for scanning, use the right arrow key or left arrow key . If no data is available, t he next bank with valid data will be recalled (empty memory banks are skipped).

6-13-1 Configure audio HPF (high pass fil t er )

The audio high pass filter is useful for limiting the audio b ass response (allowing higher tones to pass) improving intell igibility in certain circumstances (such as low frequency whistles on AM, SSB & CW).

There are four available p ass frequencies: 50Hz, 200Hz, 300Hz, and 400Hz.

The higher the frequency the more limited the audio bandwidth. For h ighest fidelity for listening, select 50Hz . The filter selection can be set to automode to select the proper filter setting automatically.

6-14 Configure Audio De-emphasis

This is really only applicable to FM mode and affects t he sharp ness of recovered audio.

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 audi o w il l sound very muffled.

The available range is as follows: THRU, 25uS, 50uS, 75 uS, and 750uS

The audio de-emphasis can be set t o aut omode to select the proper setting aut omat ically.

The default is AUTO.

Push the ENT key to accept the data and return to a st andard display. Alternatively, push the ESC key to abort entry.

Or , push the down arrow key to move to the next it em o n t he configuration menu (PRIO-CH).

6-15 Configure PRIO-CH (Priority Channel)

The priority function enables you to carry on scanning, searching or mo nitoring while the AR-ONE checks a selected freq uency 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 orig inated.

The priority function has a large number of applications and is particularly useful for

keeping an eye on a distress frequency w hile scanning or searching another freque ncy band.

Note: Dependin g upon the frequency and mode stored as priority, an audible click may be heard when the priority fu nction 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 simu ltaneously be monitored).

6-15-1 Engaging Priority channel

Once engaged, the freque ncy 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 t he 7 key.

Push the down arrow key to move the cursor to “PRIO-CH” select ion point. This menu is to configure the priority channel.

Push the ENT key to accept 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 it em o n t he configuration menu (IF output).

6-16 Configure IF output frequency

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

IF signal is to be used with an opt ional 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).

6-16-1 Selecting IF output frequen cy

To engage the priority function, push the FUNC key and then p ush t he 7 key .

Push the down arrow key to move the cursor to “IF out SEL” selectio n point. This menu is to select the I F out put frequency.

Push the ENT key to accept 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 (Reference Signal).

6-17 Configure reference signal source

The function enables you to select the reference signal of the receiver. The AR-ONE has built-in a stable reference oscil lator, however, an external high stability 10 MHz reference (such as off-air atomic coupled) can be accepted from the SMA connector (marked as 10 MHz IN) on the rear panel of the AR-ONE.

Push the down arrow key to move the cursor to “REF SEL” select ion point.

Use the main tuning dial or t he right arrow key or the left arrow key to select the desired reference signal source (i nt ernal or external). The default is INT.

7 Computer control

Connect the AR-ONE to o ne of t he 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 o f up to 99 AR-ONE to a single port for custom o perat ion, the addresses may be set between t he limits of 01 to 99 with 00 representing single radio operation.

7-1 How to send an RS-232C command

Each command comprises of tw o 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 re mote 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-ON E) DATA BIT: 8 STOP BIT: 2

PARITY: NONE XFLOW: ONE

A multiple command entry is only valid where specified. Where a mult i ple 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 t here i s no l ocal echo, either [CR] or specified response sho uld come back from the receiver after confirming the correct command. If no response has been gained after a short while, the receiver ha s failed to receive the command properly. Send a [CR] then re-send the comman d. Should problem persist, check your connect ions a nd t r y reducing the RS-232C baud rate.
