Select receive bandwidth:  For point-to-point
communications a bandwidth of 15 kHz usually provides
best results, however if adjacent channel interference is
experienced a bandwidth of 6 kHz may provide better
results.  Press 
  t
o access the I.F. bandwidth
menu then use the SUB DIAL to make the selection (in this
example select 15 kHz).  Press 
 
to accept the
selection and return to VFO mode.
If the MAIN DIAL is rotated the frequency will increment in
10 kHz...

LCD inviting you to enter the value for step-adjust (2 kHz
in the example).  Press 
 
Press  once more to return to VFO mode.  You
will note the static legend “STEP-ADJ” to confirm that
step-adjust is in operation.
Key in the start frequency (145.210 MHz in this example)
by pressing 
       .
Change frequency using the 
MAIN DIAL,  or 
keys to confirm correct operation.

used on any frequency within the set’s range.
In normal operation AUTOMODE should be used.  The
legend “AUTO” is displayed above the right hand (last)
digit of the frequency readout when automode is in
operation.
Activating AUTOMODE
To activate automode, press and hold the 
 
key for
more than one second.  The receive mode, I.F. filter
bandwidth, step, step-adjust and frequency offset will then
be automatically read from the automode bandplan data
pre-programmed...

LSB
Lower Side Band - is a form of Single Side Band (SSB).
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...

Manually selecting I.F. bandwidth.
The sequence 
  
activates the I.F. bandwidth
menu.
In normal operation the word “AUT” will be displayed in
the upper right of the LCD to signify that automode is in
operation and the I.F. bandwidth, receive mode and
channel step will be automatically selected by the AR5000
from its detailed pre-programmed bandplan data.
Selecting a new bandwidth from the list of 220, 110, 30,
15, 6 and 3 kHz is accomplished using the SUB DIAL,...

6-12  Audio tone eliminator (T-ELMT)
Various utility radio users are permitted to transmit their
signals with an accompanying continuous tone (pilot tone)
which is over ridden by the operator ’s audio (voice).  This
type of tone is transmitted continuously in order to provide
advanced security for radio communication system and
to ensure that important radio...

6-13  DTMF decoder
DTMF (Dual Tone Multi Frequency) tones are used by
many VHF/UHF communications services and amateur
radio operators to control switching devices and to enable
selective calling.  The AR5000 has the capability to decode
all 16 DTMF tones.
All 16 characters can be displayed including “1” to “0”,
“ABCD”, “#” and “*”.  The decoded DTMF characters will
automatically be displayed when the facility has been
enabled and will be removed from the display...
