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!

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

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.

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.
