Thank you for purchasing the Cobra HH 50 WX ST
handheld CB. Properly used, this Cobra product
will give you many years of reliable service.
SoundTracker®
“Cuts noise coming in...strengthens signals
going out.”
This technology dramatically improves
transmission and reception of the CB signals.
The revolutionary SoundTracker®System
reconfigures the transmission signal which
allows it to be transferred more efficiently
through cluttered airwaves.
At the same time, it significantly reduces the
amount of static on all incoming CB signals.
The end result is a cleaner, clearer sounding
reception of signals and a more powerful
transmission which dramatically improves CB
communications.

Note
SoundTracker® gives you
clearer, cleaner reception to
improve CB communications
while on the air.
The SoundTracker® System
While previous systems only “blanket out” or
limit noise in higher sound frequencies, the
revolutionary SoundTracker® System actually
reduces noise while leaving the signal intact in
the reception mode. In the transmission mode,
it actually strengthens the signal, providing you
with a significant reduction in noise on reception
and transmission.
Sound clarity is measured by the ratio
of the signal level to the noise level.
The higher the signal-to-noise ratio,
the better the sound.
How SoundTracker® Works
On Reception - “Cuts noise coming in”
With a normal CB, distant signals fall below
the squelch level and are unintelligible. With a
SoundTracker® CB. the noise level is cut up to
90%, which increases the signal-to-noise ratio
and dramatically improves signal clarity. This also
allows you to significantly reduce the squelch
level, which greatly expands your listening range.
On Transmission - “Strengthens 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.

Note
Due to the characteristics of
CB transmissions, it is
necessary to use an external
car roof/truck magnet mounted
antenna (item # HG A1000) and
a BNC S0239 adapter
(item # HA-BNC) to receive
optimal performance while in
your vehicle. See Accessories
section on page 35.
Note
The HH50RT Road trip model
comes with a magnet mounted
antenna (item #HH-Mini).
SAFETY NOTICE
MPE minimum distance for
HH-Mini Antenna
The antenna used for this
transceiver must be properly
installed and maintained and
must provide a seperation
distance of at least 12 inches (31
cm) from all persons and must
not be co-located or operated
in conjunction with any other
antenna or transmitter. Never
transmit if any person is closer
than the specified distance to
the antenna.

population. If you cannot receive a weather
station, you may not have one in your area.
A similar network of 15 stations broadcasts
continuous weather information across much
of southern Canada.
A CB Radio Can:
• Warn of traffic problems
• Provide weather and road data
• Provide help in event of an emergency
• Provide direct contact with home or office
• Assist police by reporting erratic drivers
• Get local information to find a destination
• Communicate with family and friends
• Suggest spots to eat and sleep
• Keep you alert while traveling
A Few Rules You Should Know
A. Conversations cannot last more than 5 minutes
with another station. A one minute break is
required to let others use the channel.
B. You cannot blast others off the air by use of
illegally amplified transmitters or illegally
high antennas.
C. You cannot use a CB to promote illegal
activities.
D. Profanity is not allowed.
E. You may not transmit music with a CB.
F. Selling of merchandise and/or services is
prohibited.
