accessory 12 volt fuse.

 

Connect the orange lead to a constant 12v fuse 

(ie: cigarette lighter or direct to battery).

 

Connect the black lead to the negative side of 

the au to mo bile. This is usually the chassis. Any 

con ve nient location with good electrical contact 

(remove paint) may be used.

 

Mount the microphone bracket on right side of 

the transceiver or near it using two screws sup-

plied. When mount ing in an automobile, place 

the bracket under the dash so the microphone 

is readily accessible.

 

Attach the 4-pin microphone cable to receptacle 

on front of unit and install unit in bracket securely.

Mounting and 

Connections

Note

 Before installing the CB radio, 
visually check the ve hi cle bat-
tery connections to determine 
which battery ter mi nal, posi-
tive or negative (positive is the 
larger of the two) is grounded 
to the engine block  
(or chassis).

phone bracket that is con ve nient for operation.  

In automobiles, the transceiver is usually mount-

ed to the underneath of the dash panel, with the 

microphone bracket beside it.

 

Hold the radio with mounting bracket in the 

exact location desired. Remove the mounting 

bracket and use it as a template to mark the 

location for the mounting screws.

 

Drill necessary holes and secure mounting 

bracket in lo ca tion. 

 

Connect the antenna cable plug to the re cep ta-

cle marked “ANT” on the back of the unit.

Mounting and 

Connections

Note

The transceiver is held in the 
universal mounting bracket by 
two thumb screws, permitting 
adjustment at the most con ve-
nient angle.

Marine Istallation 

When installed in a boat, the transceiver will not oper-

ate at maximum efficiency without a ground plate 

unless the vessel has a steel hull. Before installing the 

transceiver in a boat, consult your dealer for informa-

tion regarding an adequate grounding system.

Microphone Connector 

Allows for convenient removal of the microphone 

plug when storage is required. The microphone 

MUST be connected to the unit at all times when in 

use, for proper operation.

Squelch

This control is used to cut off or elim i nate receiver 

background noise in the absence of an incoming 

signal.  Adjust until the receiver noise disappears. This 

will require the incoming signal to be slightly stron-

ger than average receiver noise. Further clockwise 

rotation will increase the threshold level which a sig-

nal must overcome in order to be heard. Only strong 

signals will be heard at a maximum clockwise setting.

CB Antenna

Only a properly matched antenna system will allow 

maximum power output*.

In mobile installations (cars, trucks, boats, etc.),  

an antenna system that is non-directional should  

be used.
*Under Industry Canada regulations, this radio trans-

miter may only operate using an antenna of a type 

and maximum (or lesser) gain approved for the trans-

mitter by Industry Canada. To reduce potential radio 

interference to other users, the antenna type and its 

gain should be so chosen that the equivalent isotrop-

ically radiated power (e.i.r.p.) is not more than that 

necessary for successful communication. 
Safety notice: The device complies with the MPE 

requirements by providing a safe separation distance 

of 14.2 in (36 cm) between the antenna, including 

any radiating structure, and any persons when nor-

mally operated .  This is based on a typical installa-

tion and an antenna with 3 dBi of gain.  This device 

is approved with emissions having a source-based 

time-averaging duty factor not exceeding 50%.

Note

For optimum performance in 

passenger cars the ideal antenna 

location is on the center of the 

roof. Second choice is on the cen-

ter of the trunk.
Because many newer trucks  

feature fiberglass door skins, the 

outside mirror must be grounded 

to the chassis via a ground strap, 

if the antenna is mounted on the 

mirror bracket.
3-Way Combination Antennas 

are available which allow op er-

a tion of all three bands (AM-FM 

& CB), using a single antenna. 

However, use of this type of 

antenna usually results in less 

than normal transmit and receive 

range when com pared to a stan-

dard-type “Single Band” antenna 

designed for  CB only.

Operation

10

The SoundTracker® System reduces noise while 

leaving the signal intact in the reception mode. 

In the transmission mode, it strengthens the sig-

nal, providing you with a significant reduction in 

noise on reception and transmission.

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 by 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.

Operating Procedure to Receive
1. 

Be sure that power cord, antenna and microphone are connected to the 

proper connectors before proceeding further. The weather switch should 

be in the “CB” position.

2. 

Turn the radio ON by rotating the  VOLUME CONTROL clockwise.

3. 

Rotate SQUELCH CONTROL counterclockwise until incoming signal is 

heard.

4. 

Select the desired channel.

5. 

Set VOLUME CONTROL  to a comfortable listening level.

6. 

Engage the SoundTracker system by depressing the button labeled ST.

Listen to the background noise from the speaker. Turn the SQUELCH 

CONTROL slowly clockwise until the noise JUST disappears (no signal 

should be present). Leave the control at this setting. The squelch is now 

properly adjusted. The receiver will remain quiet until a signal is actually 

received. Do not advance the control too far, or some of the weaker signals 

will not be heard. The revolutionary SoundTracker system allows you to 

reduce unwanted background noise (static) and increase the signal for bet-

ter reception.

Operating Procedure to Transmit
1. 

Select the desired channel.

2. 

The receiver and transmitter are controlled by the press-to-talk switch on 

the microphone. Press the switch and the transmitter is activated; release 

switch to receive. When transmitting (on a clear channel), hold the micro-

phone two inches from the mouth and speak clearly in a normal voice.

Be sure the antenna is properly connected to the radio before transmit-

ting. Prolonged transmitting without an antenna, or a poorly matched 

antenna, could cause damage to the transmitter. 

 

Operation

14

Ignition Noise Interference

Use of a mobile receiver at low signal levels is nor-

mally limited by the presence of electrical noise.  

Under most operating conditions, when signal 

level is adequate, the background noise does not 

present a serious problem. Also, when extremely 

low level signals are being received, the transceiv-

er may be operated with vehicle engine turned off. 

The unit requires very little current and therefore 

will not significantly discharge the vehicle battery.
Even though this radio has an automatic noise lim-

iter, in some installations ignition interference may 

be high enough to make good communications 

impossible. Consult your COBRA dealer or a 2-way 

radio technician for help in locating and correcting 

the source of severe noise.

Temporary Mobile Operation

For temporary mobile operation, you may want to 

purchase an additional cigarette lighter adapter 

from your COBRA dealer. This adapter and a mag-

netic mount antenna allow you to quickly “install” 

your transceiver for temporary use.

Maintenance

Maintenance and Adjustment

Your COBRA CB transceiver is specifically 

designed for the environment encountered in 

mobile installations. The use of all solid state cir-

cuitry and its light weight result in high reliabil-

ity. Should a failure occur, however, review the 

following, then if necessary, replace parts only 

with identical parts. Do not substitute.

1. 

Check connections to the source of power and 

make sure it is the 13.8 VDC required to oper-

ate your radio.

2. 

Check the fuses in the DC power cord. The 

main power lead (red & orange wire) has a 2 

amp 3AG type fuse in its holder. Use only the 

above specified type and size fuse for maxi-

mum protection. Failure to do so, will void the 

warranty.

3.  Make certain the microphone is properly 

plugged in.

4. 

Make certain the antenna is properly assem-

bled and connected.

If you are unable to correct the problem, refer 

to the  SERVICE INSTRUCTIONS at the end of this 

manual for the correct procedure for warranty 

and post-warranty service from COBRA. 

Permitted: 

“A tornado sighted six miles of town.”

Not Permitted : 

“This is observation post number 10.   

No tornado sighted.”

chase. This warranty does not cover damages due to careless handling, 

negligence, accident, abuse or failure to follow operating instructions. 

Alteration of this product or defacing of the serial number cancels all 

obligations of this warranty. This warranty gives you specified legal rights. 

Additional warranty rights may be provided by law in some areas. 

For Products Purchased in the U.S.A.

Cobra Electronics Corporation warrants that its Cobra CB radios, and the 

component parts thereof, will be free of defects in workmanship and

chase. This warranty may be enforced by the first consumer purchaser, 

provided that the product is utilized within the U.S.A. 
Cobra will, without charge, repair or replace, at its option, defective CB 

radios, products or component parts upon delivery to the Cobra Factory 

Service department, accompanied by proof of the date of first consumer 

purchase, such as a duplicated copy of a sales receipt. 
You must pay any initial shipping charges required to ship the product 

for warranty service, but the return charges will be at Cobra’s expense, if 

the product is repaired or replaced under warranty. 
This warranty gives you specific legal rights, and you may also have other 

rights which may vary from state to state.

Exclusions

: This limited warranty does not apply: 1) To any product dam-

aged by accident; 2) In the event of misuse or abuse of the product or as 

a result of unauthorized alterations or repairs; 3) If the serial number has 

been altered,  defaced or removed; 4) If the owner of the product resides

chantability and fitness for a particular purpose are limited in duration to 

the length of this warranty. Cobra shall not be liable for any incidental, 

consequential or other damages; including, without limitation, damages 

resulting from loss of use or cost of installation. 
Some states do not allow limitations on how long an implied 

warranty lasts and/or do not allow the exclusion or limitation of 

incidental or consequential damages, so the above limitations may not 

apply to you.

IC & FCC Regulations

Industry Canada Notice: This device complies with Industry Canada 

licence-exempt RSS standard(s). Operation is subject to the following 

two conditions: 1) this device may not cause interference, and 2) this 

device must accept any interference, including interference that may 

cause undesired operation of the device.
«IC» before the equipment certification number signifies that the 

Industry Canada technical specifications were met. It does not guaran-

tee that the certified product will operate to the user’s satisfaction.

FCC Regulations

FCC regulations permit only “transmission” (one-party to another) 

rather than “broadcast” (to a wide audience). Thus, advertising is not 

allowed on CB channels because that is “broadcasting”.

FCC Warnings

All transmitter adjustments other than those supplied by the man-

ufacturer as front panel operating controls, must be made by, or 

under the supervision of, the holder of an FCC-issued general Radio-

Telephone Operator’s License.
Replacement or substitution of transistors, regular di odes or other 

parts of a unique nature, with parts other than those recommended 

by Cobra, may cause violation of the tech ni cal regulations of Part 95 

of the FCC Rules, or violation of Type Acceptance requirements of 

Part 2 of the Rules.
You should read and understand Part 95 (included with this unit) of the 

FCC Rules and Regulations, before operating your Cobra radio, even 

though the FCC no longer requires you to obtain an operator’s license.

Controls and Indicators

Thank you for purchasing the Cobra 18 WX ST II 

CB Radio Transceiver. Properly used, this Cobra 

product will give you many years of reliable service.

“Cuts Static coming in, adds Punch going out!”

Technology that dramatically improves the 

transmission and reception of CB radio signals.
The revolutionary SoundTracker

®

 System  

reconfigures the transmission signal which allows 

it to be transferred more effectively through  

cluttered airwaves.
At the same time, it significantly reduces the 

amount of static on all incoming CB signals.
The end result is a clearer, cleaner sounding 

reception of signals and a more powerful  

transmission which dramatically improve 

CB communications.
