specific requirements... the lower level settings may not
be usable when high noise is present.
12-17 PROGRAM SEARCH - VOICE
The search VOICE parameter determines the way in which
an active frequency is determined by sampling the audio
modulation. When the VOICE search facility is enabled,
the search process will only stop on active channels which
have modulation (such as voice) present. The AR5000
will not remain on unmodulated frequencies (such as blank
carriers).
You may find this facility useful for skipping over STRONG
signals but WEAKER noisy signals and transmissions with
pilot tones or heterodynes present may fool the receiver
into thinking that modulation is present. Experimentation
will certainly be required with different types of signal.
The limits are OFF and 1 to 255 (default OFF).

Either use the
MAIN DIAL
or
SUB DIAL
to change the value.
The
key may be used as a short cut to OFF. If the
is used to select OFF, use of the
MAIN DIAL
and
SUB DIAL
afterwards will result in the value continuing from
whatever was last selected, this speeds up the selection
process. In fact the
key may be used as a toggle
between OFF and the new setting.
The legend “*” positioned to the right of the word “
VOICE

”
(to the left of the numeric value) indicates that the current
audio will open the squelch, use the
SUB DIAL
to increase
the value until the “*” legend disappears, you can then be
sure that the search voice setting will ignore and skip over
the current frequency.
While in program search mode, the LCD legend “VCS”
for voice squelch is displayed toward the top right hand
side of the LCD to indicate that voice squelch is in
operation.
To accept the changes to VOICE SQUELCH, press
to return to a normal display (SCAN, SEARCH or
VFO mode). Alternatively you may move to the next option
(AUTO-STORE) by pressing the
key.
12-18 Cyber Search
A special facility has been provided to speed up the search
process (which is capable of searching about 25
frequencies per second), typically the speed increases to
about 45 frequencies per second as long as the step size
is set to 100 kHz or less.
When Cyber Search has been selected, both the
frequency and text are blanked out from the display while
searching, the words “
CYBER SRCH
CYBER SRCH
CYBER SRCH
CYBER SRCH
CYBER SRCH
” being displayed
in their place. While searching, the legend “
SR
SR

” is
displayed on the extreme right of the display to indicate
that search is in progress (exact position dependant on
whether PROGRAM SEARCH, SIMPLE SEARCH or
MANUAL SEARCH has been selected.
When a busy channel is located, the FREQUENCY or
TEXT will be displayed (taking the place of the Cyber
Search legend), the “BUSY” legend indicates when an
active frequency has been located.
A group of three digit numbers counting from “

indicate that the Cyber Search process is proceeding...
the rolling numbers do not have any specific meaning,
they are like the rolling drums of a fruit machine! If nothing
were displayed to show that Cyber Search was in
operation and no transmissions were encountered, the
AR5000 may otherwise look like it was doing nothing.
To enable Cyber Search press
then press and
hold the
key for more than one second... a bleep
will then sound and the “FUNC” legend will be removed
from the LCD to confirm operation. This key sequence
acts as a toggle to switch Cyber Search on and off.
Cyber Scan and Cyber Search are selected using the
same key sequence, the command being global, if
CYBER status is changed in search mode, it will affect
scan mode as well.
Note: If no text has been saved in the program search
bank and TEXT mode has been selected rather than
FREQUENCY, the display will be void of information when
Cyber Search locates a busy channel !!
