Mounting and Connections
The Ju n ction Box is held by two scre ws,pe rm i t t i n g
mounting in the manner most convenient for
your installation.
Mounting hardware is supplied for mounting the
Junction Box.The mounting must be mechanically
s t rong and also provide a good elect ri cal co n n e ct i o n
to the chassis of the vehicle.Proceed as follows to
mount junction box:

Caution
Leaving the 75 WX ST on after
your car is turned off can drain
your car batte ry when co n n e cte d
to a constant 12 volt source.
When co n n e cted to an acce s s o ry
12 volt source the unit will turn
off when vehicle is turned off.

After you have dete rmined the most co nve n i e nt
location in your vehicle, hold the Cobra HH-75
WX ST Junction Box in the exact location
desired. If nothing will interfere with mounting
it in the desired position,use the Junction Box
as a template to mark the location for the
mounting screws.Before drilling the holes,
make sure nothing will interfere with the
installation of the mounting screws.

InstallationInstallation
The alternator and ignition system in your vehicle
may limit your ability to receive low signal levels.
Other noise interference can be the result
of several different installation variables.Consult
your Cobra dealer or a 2-way radio technician to
help locate and correct the source of severe noise
interference.
CB Antenna
For the most reliable
operation and maximum
range, Cobra recom-
mends using a vertically
polarized, quarter wave
length whip antenna
(illustration A).
Shorter,loaded-type
whips are adequate when
maximum range is not
required (illustration B)

Note
Mobile installations (cars,
trucks,boats,etc) should be
made only with a non-direc-
tional antenna system.
A standard antenna connector
(Type SO-239) is provided on
the Connector Box for easy con-
nection to a standard PL-259
cable termination.
Cobra antenna models are
recommended;see your
local CB dealer or order directly
from Cobra.See order form
on page 39.
For maximum efficiency in boat
installations,a ground plate is
required,unless the vessel has a
steel hull. Consult your CB deal-
er for information regarding an
adequate grounding system.

“Cuts Noise Coming In”
With a normal CB,d i s t a nt signals fall be l ow
the squelch level and are uninte l l i g i b l e.With
a So u n d Tra c ker CB,the noise level is cut by up
to 90%,which increases the signal-to-noise
ratio and dra m at i cally improves signal clari ty.
This also allows you to significa ntly re d u c e the

On Tra n s m i s s i on–
“St rengthens Signals Going Out”
A SoundTracker CB strengthens the transmit
signal by more effectively using the available
RF power output of the CB.The result is
improved transmission signal clarity and an
expanded transmission range.

If you turn the squelch control fully counter-

that everything gets through - noise,weak
signals and strong signals.
To set the “squelch gate”to the DSS-Desired
Squelch Setting, turn the squelch control
counterclockwise until you hear noise.Then
turn the squelch control back clockwise just
until the noise stops. Now only strong signals
get through.
The Desired Squelch Setting, (DSS) only allows
actual transmissions to come through. This
effectively blocks out unwanted noise.

WEATHER CHANNEL MESSAGES
You can receive up to the minute local area
weather reports provided by NOAA (National
Oceanic Atmospheric Administration) 24
hours a day,
7 days a week. An agency of the U.S.
Department of Commerce, NOAA warns of
dangerous weather,charts our seas and skies,
guides our use and protection of ocean and
coastal resources and conducts research to
improve our understanding and stewardship
of the environment.
The National Weather Service operates about
380 stations.Approximately 90 percent of the
Nation’s population is within listening range
of a NOAA Weather Radio broadcast.
A similar network of about 15 stations using the
same frequencies broadcast continuous weath-
er information across much of southern
Canada.
If you have a question concerning NOAA
Weather Radio or wish to receive a listing of
NOAA Weather Radio receiver locations,
please contact your nearest National Weather
Service Office, or write to National Weather
