					Programming your
     RACAL
   It’s Easy to Do
One of the best
features of the Thales
Racal radio is the ease
of programming new
channels into the
radio. There are
various times that you
will have to add
channels.
First of all, you must be
authorized to use the
new frequencies.
Channels on the ICS-205
at an incident,
frequencies supplied by
your supervisor, or from
your briefing at an off-
district assignment are
authorized for your use.
These new frequencies
are only to be used while
you are involved with the
new assignment. Do not
continue to use them
while returning home or
after you are back.
Likewise, don’t use our
frequencies while you
are off District.
After you have received your frequency
list it is time to start the programming
process. Review the list and create
unique names for the channels that are
8 characters or less in length. If you are
programming these in the main bank,
they cannot exactly duplicate any
names that have been already used.
                              SOA RPTR is good

                               GERLACH1 would be needed
                               as GERLACH is in main bank
                              BL LAKE would be needed
                              As BLUELAKE is in main bank

                              ?

                              ?
The names should reflect
the use or location of the
frequency. “DIV A”, “MAIN
RPT”, “CAMP”, and “A2G
WEST” would be good
names for Division A, the
main incident repeater, the
inter-camp net, and Air-to-
Ground on the west side.
Select a user
programmable Zone or a
Zone in the Event Bank.
Our regular channels are
locked to avoid
overwriting them.
Place the radio in
programming mode by
pressing ENTER,
selecting PROGRM and
pressing ENTER. The
radio will ask for a
password and enter
“000000”, the default
password. Select
CHANEL.
Depending upon whether
or not the channel was
previously programmed,
you will see “EMPTY” or
an ID and TAG with the
old channel name. Just
pressing ENTER and
then scrolling down to
TAG will allow you to
enter a channel name.
ID is set by the radio and
you cannot change it. If it
is an existing channel,
reprogramming will
change the data in all
appearances of that
channel in the radio. If
there is a little padlock in
the lower right corner,
the channel is locked.
Enter your channel
name. Like a cell phone,
you may need to push a
button several times to
get the right letter or
number. You can back
up with the arrow
softkeys to correct a
mistake.
The “1” key will give you
a space, and the “*” key
will give you the special
characters *.&<>-+=:!%;?
as well as a space. All
labels are displayed as
capital letters with
keyboard programming.
The curser will advance
to the next space in
about 1.5 seconds after
you press a key.
Remember, you can use
the arrow softkeys to
correct a mistake. Press
ENTER to accept the
name and then scroll
down to MODE.
MODE is where you set the
modulation characteristics
of the radio. We are
primarily using ANALOG
channels, though DIGITAL
ones are used for special
purposes like crew nets.
Select the correct MODE.
In ANALOG mode, B/W
(bandwidth) will need to be
set. All Federal Frequencies
will be Narrowband – 12.5
kHz. Cooperators, like
VFDs, sheriffs and state
forestry departments, may
have Wideband – 25 kHz
channels.
         Federal frequencies will
         usually be between 162 and
         174 MHz, and these must
Narrow
         be narrowband.
         Cooperators usually have
         frequencies between 150
         and 162 MHz. Below 150
Wide
         MHz there is a mix of
         government, commercial
         and Amateur Radio.
The next screen is for
encryption. It should always
be set for disabled
(DISABD). Only the Law
Enforcement radios have
encryption at this time.
Scroll down to the Receive
(RX) screen.
This is where you enter the
receive frequency. The radio
will not accept a frequency
that is out of range or is an
invalid channel. The decimal
point is always added after
the third number entered.
You can use the softkey
arrows to correct mistakes.
RXSQMD is where you set
your receive squelch. On
most of our channels, we
use carrier or NOISE
squelch as it is called in this
radio. When there is enough
signal on the channel, the
squelch opens and sends
audio to the speaker.
When you select NOISE,
you will have the
opportunity to initially set
the squelch level. The
default setting usually works
fine. You can always
change this setting with the
MONITOR button on the
side of the radio.
Other RX squelch settings
are NONE, DCS and
CTCSS. NONE sets the
radio in open squelch and
the channel will always be
noisy. DCS tones are used
by some cooperators, but
CTCSS tones may be
commonly used in
communication plans.
Receive CTCSS tones may
be specified on a
communications plan to
eliminate squelch opening
from unwanted signals.
Many users use these in
radio noisy urban
environments for this
purpose.
To set a tone, select
CTCSS and the TON line
will appear on the display.
You can scroll through the
correct tones to find the one
listed on the plan. If you
cannot find the one that is
listed on the plan, there is
an error in the plan so
contact the radio tech.
The next screen sets the
transmit (TX) frequency.
Enter the transmit frequency
the same way you did the
receive frequency. If this is
a “Receive Only” frequency
like the Weather, put all
zeros in for the frequency.
TXSQMD (Transmit squelch
mode) can be set to NONE,
CTCSS or DCS in analog
mode. If you select CTCSS,
it will display TON and you
can set the tone to the
correct value from your
programming list.
The next screen will allow
you to set your transmit
power. Default is 1 watt LO
and 5 watts HI. For some
applications we will set
these lower and that will
conserve batteries.
Reducing power also helps
avoid interference with other
users.
 If the channel was EMPTY
when you started, the radio
will ask you if you want to
save the new channel.
Press ENTER to save the
channel and it will revert to
that channel in regular
operational mode.
After programming an
empty channel, if you wish
to program another channel,
you would have to re-enter
programming mode. You
will not be asked for a
password again until you
turn the radio off and on.
If you programmed over an
old channel, when you scroll
past the power screen, you
will come back to the ID-
TAG screen. You can ESC
out if you are ready to use
the radio, or you can use
the channel selector to go to
the next channel to
program.
When you finish
programming, you will want
to turn the radio off and on
to reset it.
Digital channels
require setting the
NAC (network access
code) and the TG
(talkgroup) These may
be different for the
transmit and receive.
              NACs come in two flavors,
HEX NAC
              decimal and hexadecimal.
              The Racal will only take hex
              NACs at this time.
              Generally, decimal NACs
              will have 4 digits and hex
              will have 3. Besides the
Decimal NAC   usual 0-9, hex includes A,
              B, C, D, E, and F.
If you have any question
about whether or not a NAC
is hex or decimal, ask. If
they are in decimal form,
ask the tech to perform the
conversion. The computer
radio programmer can
perform the conversion and
they can also be done with
the Windows scientific
calculator.
It is important to enter the
leading zero(s). The letters
can be selected by multiple
presses of the 2 or 3 key.
The NAC will default to
0x293. “0x” prefix, or the “h”
or “$” suffix denotes hex
and are not entered into the
radio. (0x293=293h=293$)
                       Think of the NACs as the

There are a couple of
special NACs. 293$ is the
default NAC. 0xF7E and
F7Fh are the equivalent of
carrier squelch, they will
open the receiver on any
digital signal with any
transmitted NAC.
On the RXSQMD screen you
can select P25MON,
P25SEL,or P25NOR. P25SEL
requires the correct NAC and
the correct talkgroup in order to
open the squelch. P25MON will
open on all non-encrypted
digital signals. P25NOR will
open on any talkgroup but
requires the correct NAC.
The TX screen will require a
NAC. The TXSQMD will
always be P25SEL.
TALKGP defaults to 00001.
Enter the correct talkgroup
or the “all talkgroup” number
65535.
The power screen is the
same as on the analog
channel. On inter-crew
frequencies, you might be
directed to use lower power
settings to avoid
interference with other
users.
There are other menus in
the programming area.
GLOBAL contains items
that affect the entire radio.
LITE will allow you to set
the brightness of the
display. DIM and BRIGHT
use almost the same power.
LT DLY is the time the light
stays on when you press a
key or the squelch opens. It
is set at 5 seconds.
LTONRX can be set to ON
for a light when the squelch
opens.
TOT is the transmitter time
out timer. It should be set to
120 seconds or less. This
prevents a stuck PTT switch
from keeping the radio in
transmit and clogging the
channel.
DISPLY can be set to
ALPHA or NUMBER.
NUMBER will display the
receive frequency on the
channel screen, or the
transmit frequency when the
PTT is pressed. ALPHA is
the default.
UNIT ID should be left ON.
In Digital mode, an identifier
is sent. Each radio is
assigned a unique number.
This will allow some new
communications options
with digital channels in the
future.
HOM is a home channel.
This is useful if you have a
button programmed as a
home button or with the
HOME function in the main
menu to go to your home
channel. It stays on that
channel until you change
channels, zones, or turn the
radio off.
EMG is used to set the
channel for the red button.
Since the red button is not
activated, it does nothing.
ALERT changes the
function of the emergency
activation of the red button if
it were activated.
TX INH is also known as
“busy channel lockout”. It
is used to prevent you
from transmitting on top
of another station.
Default is NONE. This
may be used in the near
future.
RPTR is reserved for
future use. BAUD is used
to set the communication
rate for external data
devices. Please leave it
at 9600.
The best way to keep
current on your radio
programming skills is to
practice. Programming a
channel each week will
only take a couple of
minutes, but will keep
you current.
