pass filter setting (AUTO / 50Hz / 200Hz / 300 Hz or 400Hz). 
 
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 (LPF). 
 
6-13-2 Configure audio LPF (low pass filter) 
The audio low pass filter is useful to cut off high tones (allowing low tones to pass) to 
improve intelligibility of weak signals in close proximity to adjacent interference and to 
remove hiss making listening for extended periods easier on the ears. 
 
There are four available pass frequencies:    3KHz, 4KHz, 6KHz and 12KHz. 
 
The lower the frequency the more limited the audio bandwidth. For highest fidelity for 
listening, select 12.0KHz. The filter selection can be set to automode to select the proper 
filter setting automatically. 
 
The default is AUTO. 
 
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 “LPF” selection point.   
This menu is to configure the low pass filter. 
  
Use the main tuning dial or the right arrow key or the left arrow key to select the desired 
high 
pass filter setting (AUTO / 3KHz / 4KHz / 6KHz or 12KHz). 
 
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   
(De-Emphasis). 
 
6-14 Configure Audio De-emphasis 
This is really only applicable to FM mode and affects the sharpness of recovered audio.  
						

							 61 
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. 
 
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 “De-Emphasis” selection point.   
This menu is to configure the audio de-emphasis. 
  
Use the main tuning dial or the right arrow key or the left arrow key to select the desired 
de-emphasis setting (AUTO / THRU / 25uS / 75uS or 750uS). 
 
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   
(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  
						

							 62 
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. 
Push the down arrow key to move the cursor to “PRIO-CH” selection point.   
This menu is to configure the priority channel. 
  
Use the main tuning dial or the right arrow key or the left arrow key to select the desired   
priority channel. 
 
Push the downward key to select the time interval. 
Use the main tuning dial or the right arrow key or the left arrow key to select the desired 
time 
interval for the priority channel. 
 
Push the ENT key to accept data and return to a standard display.   
Alternatively, push the ESC key to abort entry.    
						

							 63 
 
Or, push the down arrow key to move to the next item on the 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 
2
nd 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).   
 
6-16-1 Selecting IF output frequency   
To engage the priority function, push the FUNC key and then push the 7 key. 
Push the down arrow key to move the cursor to “IF out SEL” selection point.   
This menu is to select the IF output frequency. 
  
Use the main tuning dial or the right arrow key or the left arrow key to select the desired   
IF output 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  
						

							 64 
The function enables you to select the reference signal of the receiver. 
The AR-ONE has built-in a stable reference oscillator, 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” selection point.   
  
Use the main tuning dial or the right arrow key or the left arrow key to select the desired   
reference signal source (internal or external). The default is INT. 
 
Push the ENT key to accept data and return to a standard display.   
Alternatively, push the ESC key to abort entry. 
This completes the configuration settings. 
7    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  
						

							 65 
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.
