INTRODUCTION TO AMATEUR
RADIO
This transceiver is a great intermediate-level tool for the experi-
enced amateur radio operator. The transceiver opens a door for
you to the world from almost anywhere! All you need is an Ama-
teur Radio Operator’s License (Novice Class, or Technician Plus,
or higher) issued by the Federal Communications Commission
(FCC). If you do not have a license, it is easier than ever to get
one and help from licensed operators is available. Here are a few
tips to help you get started.
You can turn on your transceiver and scan the entire band to hear
what is going on; however, do not attempt to transmit until
you get your license. If you transmit without a license, you are
in violation of federal law. That violation can lead to severe pen-
alties. Note that ham operators take the FCC rules very seriously
and want nothing to do with “bootleggers” — their term for people
who operate without a license.
Find out if there is a ham radio club in your area. Most clubs wel-
come newcomers and are glad to help you get your license.
There are thousands of clubs across the country, so there is prob-
ably one in or near your own community. Often, the staff at your
local RadioShack store can help you locate a club.
If you do not hear anyone talking about a local club in your area
as you listen to local transmissions, write to the American Radio
Relay League (ARRL) at the following address, to find out how to
contact a local affiliate. The ARRL is the national organization
representing amateur radio in the United States. The league has
more than 150,000 members. Most are ham operators, or mem-
bers in the process of obtaining their license.

Start studying for the license exams. Do not be intimidated by the
word “study,” for most people can go from knowing absolutely
nothing about amateur radio to passing the Novice and Techni-
cian written exams in less than a month.
The exams test your knowledge of basic radio regulations and el-
ementary radio theory. Many clubs hold license classes, which
can be a fun and easy way to learn about amateur radio. There
are good books, cassette tapes, computer programs, and many
other study aids available. Your local RadioShack store sells
FCC
study guides for amateur radio operator li-
License Preparation
censes. While you are no longer required to learn Morse code for
a Technician Class license, we encourage you to learn it anyway
so you can advance to higher levels of operating privileges.
The examiners for a Novice license test can be any two ham op-
erators who hold a general or higher class license and who are at
least 18 years old and are not related to you. There is no fee to
take the Novice exam. As soon as you pass the Novice exam,
you can immediately take the Technician exam. There is a small
fee required for taking the Technician exam, and the test must be
administered by a three-member Volunteer Examiner Team.
Contact the ARRL for a schedule of exam opportunities in your
area.
A Novice Class or Technician Plus (or higher) license lets you use
the HTX-10 to communicate directly with other operators.
Amateur radio is a great hobby that has enriched the lives of mil-
lions of people all over the world. The ARRL would be glad to hear
from you if you need more information or would like to join!

PREPARATION
ATTACHING THE MICROPHONE
HOLDER
You can connect the microphone holder horizontally or vertically
to either side of the transceiver or to another location in your ve-
hicle.
Use the supplied screws and lock washers to secure the holder
to the side of the transceiver.
Or, follow these steps to attach the holder to another location in
the vehicle (such as the dashboard).
1. Using the holder as a template, mark the positions for the
mounting screw holes at the desired location.
2. At each marked position, drill a hole slightly smaller than the
supplied mounting screws.
Caution:
Be careful not to drill into anything behind the
mounting surface.
3. Attach the holder at the mounting location using the sup-
plied machine screws and lock washers.
MOUNTING THE TRANSCEIVER
The most common mounting location for this transceiver is under
a vehicle's dashboard. If you use the HTX-10 as a base station,
however, you can place it on a desk, shelf, or table (see “Using
the Transceiver as a Base Station” on Page 14).
8
If you are mounting the transceiver in a vehicle, choose a loca-
tion where:
• you can easily reach the transceiver.
• wires and cables are clear of the vehicle's pedals or other
moving parts.
• the transceiver is not directly in front of heating vents.
• all wires and cables can reach their connection points.
Warning:
If you use the transceiver in a vehicle, mount it securely
to avoid damage to the transceiver or vehicle, and to avoid injury
to anyone in the vehicle during sudden starts or stops.
Follow these steps to mount the transceiver using the supplied
hardware.
1. Using the mounting bracket as a template, mark the posi-
tions for the screw holes on the mounting surface.
2. In each marked location, drill a hole slightly smaller than the
supplied mounting screws.
Caution:
Be careful not to drill into objects behind the
mounting surface.
3. Using a Phillips screwdriver, attach the mounting bracket to
the mounting surface with the supplied mounting screws
and flat washers.
9
4. Attach the transceiver to the mounting bracket using the
supplied rubber washers and mounting knobs.
(Rubber washers
not shown)
CONNECTING AN ANTENNA
There are many different types of transceiver antennas for mobile
transceivers. Each antenna type has its own benefits, so choose
the one that best meets your needs. Your local RadioShack store
sells a wide variety of antennas.
Note:
If you are using this transceiver as a base station, see “Us-
ing the Transceiver as a Base Station” on Page 14.
When you choose an antenna, keep in mind that for the best
performance you should mount the antenna:
• as high as possible on the vehicle
• as far as possible from sources of electrical noise
• vertically
10
Once you choose an antenna, follow
its mounting instructions. Then route
the cable to the transceiver and con-
ANT
nect the cable to the
jack on the
back of the transceiver.
Cautions:
• Avoid routing the cable next to
sharp edges or moving parts,
which might damage the cable.
• Do not run the cable next to
power cables or other radio
antenna cables.
• Do not run the cable through the engine compartment or
other areas that produce extreme heat.
To achieve your radio's maximum range, adjust the antenna's
Standing Wave Ratio (SWR). You can use an SWR meter (not
supplied) to adjust the SWR for your antenna.
Follow the instructions supplied with the SWR meter and antenna
to adjust your antenna's SWR to the lowest possible value. SWR
values of 2.0:1 are generally acceptable, with readings of 1.5:1 or
lower being more desirable.
Caution:
You might damage your transceiver if you use it at a
high SWR value.

CARE AND MAINTENANCE
Your HTX-10 10-Meter Transceiver is an example of superior
design and craftsmanship. The following suggestions will help
you care for your transceiver so you can enjoy it for years.
Keep the transceiver dry. If it gets wet, wipe it dry
immediately. Liquids might contain minerals that
can corrode the electronic circuits.
Use and store the transceiver only in normal tem-
perature environments. Temperature extremes
can shorten the life of electronic devices and dis-
tort or melt plastic parts.
Keep the transceiver away from dust and dirt,
which can cause premature wear of parts.
Handle the transceiver gently and carefully.
Dropping it can damage circuit boards and cases
and can cause the transceiver to work improper-
ly.
Wipe the transceiver with a damp cloth occasion-
ally to keep it looking new. Do not use harsh
chemicals, cleaning solvents, or strong deter-
gents to clean the transceiver.
Modifying or tampering with the transceiver’s internal compo-
nents can cause a malfunction and might invalidate its warran-
ty and void your FCC authorization to operate it. If your
transceiver is not performing as it should, take it to your local
RadioShack store for assistance.
27
TROUBLESHOOTING
If your transceiver is not working as it should, these suggestions
might help you eliminate the problem. If the transceiver still does
not operate properly, take it to your local RadioShack store for as-

The transceiver should be serviced only by a qualified radio
technician. If you still have problems, take your transceiver to a
local RadioShack store for assistance.
NOISE REDUCTION
Because your transceiver is exceptionally quiet, any noise you
hear is probably from an external source in your vehicle such as
your vehicle’s alternator, radio, or spark plugs.
To solve the problem, you must go to the noise's source. You
can determine the noise's source by turning off the engine and
operating the transceiver with your vehicle's ignition set to ACC.
If the noise decreases, the problem is in your vehicle’s ignition
or electrical system.
Here are a few hints to help you reduce or eliminate such
noise:
• Make all transceiver power and antenna wires as short as
possible.
• Route the power wires away from the antenna wires.
Download from Www.Somanuals.com. All Manuals Search And Downloa2d9.
• Be sure that the chassis ground connection is secure.
• Replace old ignition wires with new, high-voltage, noise sup-
pression wires.
• Install noise suppressors on your spark plugs, or install new
spark plugs that have built in noise suppressors.
• If problems persist, check your alternator/generator and reg-
ulator gauges. You can reduce the noise from these sources
by using bypass capacitors at the various output voltage
points.
Your local RadioShack store has a wide selection of noise sup-
pression accessories.
REPLACING THE FUSE
If the HTX-10 stops operating, you might need to replace the red
power wire’s fuse with the supplied spare fuse.
Caution:
Do not use a fuse with ratings other than those speci-
fied here. Doing so might damage your transceiver.
Follow these steps to replace your transceiver’s fuse.
1. Make sure the power source and transceiver are both off.
2. Pull the latches apart on the fuse holder until it opens.

3. If the fuse is blown, replace it. Use only a standard 1 / × /
inch fast-acting fuse with the proper rating. The fuse must
be 10 amps.
30
Caution:
The supplied fuse has the proper ratings. Make
sure you replace a fuse only with another fuse of the same
rating.
4. Reassemble the fuse holder by squeezing it together until it
snaps shut.

OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE
LIMITED IN DURATION TO THE DURATION OF THE WRITTEN LIMITED WAR-
RANTIES CONTAINED HEREIN. EXCEPT AS PROVIDED HEREIN, RadioShack

RadioShack HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Some states do not allow limitations on how long an implied warranty lasts or the ex-

of warranty service. Repaired or replaced parts and products are warranted for the
remainder of the original warranty period. You will be charged for repair or replace-
ment of the product made after the expiration of the warranty period.
This warranty does not cover: (a) damage or failure caused by or attributable to acts
of God, abuse, accident, misuse, improper or abnormal usage, failure to follow in-
structions, improper installation or maintenance, alteration, lightning or other inci-
dence of excess voltage or current; (b) any repairs other than those provided by a
RadioShack Authorized Service Facility; (c) consumables such as fuses or batter-
