FEATURES
Your RadioShack DX-398 All-Band
Shortwave Receiver with Radio Data
System brings you the voices of the
world. In the 14 international short-
wave (SW) bands, you can hear news
broadcasts and other programs from
sources around the world, such as the
British Broadcasting Corporation, Ra-
dio Cairo, and Radio Beijing. You can
set your receiver so it displays Radio
Data System (RDS) call letters of
those stations that transmit an RDS
signal.
You can get emergency information
firsthand by listening to amateur radio
broadcasts, including single sideband
(SSB) voice transmissions.
In the longwave (LW) band, you can
hear ship-to-shore calls, other marine
and aeronautical services, and some-
times even hurricane reports. You can
also tune to local broadcasts in the FM
and medium-wave (MW) bands. (In the
United States, we commonly call the
MW band the AM band.)
In addition, you can connect a cassette
recorder to the receiver’s record line
out and standby jacks so you can di-
rectly record your favorite programs
live or at a preset time.
Your receiver’s features include:

PREPARATION
CONNECTING TO
POWER
You can power the receiver from inter-
nal batteries, standard AC power, or
your vehicle’s battery.
Installing Internal Batteries
You can use four AA batteries (not
supplied) to power the receiver. For
the best performance and longest life,
we recommend alkaline batteries,
available at your local RadioShack
store.
Cautions:
Always use fresh batteries of the
required size and type.
Do not mix old and new batteries
or different types of batteries
(standard or alkaline).
Follow these steps to install the batter-
ies.
1. Remove the battery compart-
ment’s cover by sliding the cover
in the direction of the arrow on the
cover’s tab.
2. Slide four AA batteries into the
compartment on top of the lift-out
ribbon, according to the polarity
symbols (+ and –) marked next to
the compartment.
3. Replace the cover.
Cautions:
If you will not be using the receiver
with battery power for several
months, remove the batteries.
Dispose of old batteries promptly
and properly.
Using Standard AC Power
To power the receiver from standard
AC power, you need an optional AC
adapter, such as Cat. No. 273-1662.
Note: Connecting an AC adapter dis-
connects internal batteries.
Caution: You must use a
Class 2 power source that
supplies 6 volts DC and deliv-
ers at least 300 mA. Its center tip must
be set to negative and its plug must fit
the receiver's DC IN 6V jack. The rec-
ommended adapter meets these
specifications. Using an adapter that
does not meet these specifications
could damage the receiver or the
adapter.
!
8
When you finish using the AC
adapter, unplug it from the AC out-
let first, then disconnect it from the
receiver.
Follow these steps to use AC power.
1. Set the adapter’s voltage switch to
6V.
2. Line up the 5.5 mm outer diam-
eter/2.1 mm inner diameter
barrel plug with the adapter’s
socket so it reads –TIP
, and insert
the plug into the socket.
3. Insert the barrel plug into the
receiver’s
DC IN 6V jack.
4. Plug the adapter into a standard
AC outlet.
Using Vehicle Battery Power
To power the receiver from your vehi-
cle’s battery, you need an optional DC
cigarette lighter adapter, such as Cat.
No. 273-1802.
Caution: You must use a DC
cigarette lighter adapter that
supplies 6 volts DC and deliv-
ers at least 300 mA. Its center tip must
be set to negative and its plug must fit
the receiver's DC IN 6V jack. The rec-
ommended DC cigarette lighter adapt-
er meets these specifications. Using
an adapter that does not meet these
specifications could damage the re-
ceiver or the adapter.
Caution: Always plug the DC ciga-
rette lighter adapter into the receiver
before you plug it into your vehicle's
cigarette-lighter socket. Always un-
plug the adapter from the vehicle's
cigarette-lighter socket before you un-
plug it from the receiver.
Follow these steps to power the re-
ceiver from your vehicle’s battery.
1. Set the DC cigarette lighter
adapter’s voltage switch to 6V.
!
9
2. Insert the adapters barrel plug
into the receiver’s DC IN 6V jack.
3. Push the adapter’s plug into the
vehicle’s cigarette-lighter socket.
ADJUSTING THE
TELESCOPING
ANTENNA
For the best reception, adjust the tele-
scoping antenna for the desired band.
FM — Pull up the antenna base about
halfway then fully extend the antenna
and rotate it for the best reception.
LW and MW (AM) — Rotate the re-
ceiver. The receiver uses a built-in an-
tenna for these bands.
SW — Pull up the antenna base then
fully extend the antenna and point it
straight up.
CONNECTING AN
EXTERNAL ANTENNA
To improve SW/MW/LW reception,
you can connect an optional external
antenna (such as Cat. No. 20-181) di-
rectly to the AM EXT ANT jack on the
left side of the receiver. This automati-
cally disconnects the receiver’s built-in
antenna.
Follow the antenna’s supplied instruc-
tions to connect it to the receiver.
10
CONNECTING
HEADPHONES
For private listening and for stereo
sound during FM stereo broadcasts,
you can plug optional stereo head-
phones with a 1/8-inch (3.5 mm) plug
(available at your local RadioShack
store) into the jack on the left side of
the receiver. This automatically dis-
connects the internal speaker.
When you connect stereo headphones
and tune to a stereo broadcast,
appears on the display.
Listening Safely
To protect your hearing, follow these
guidelines when you use headphones.
Do not listen at extremely high
volume levels. Extended high-vol-
ume listening can lead to perma-
nent hearing loss.
Set the volume to the lowest set-
ting before you begin listening.
After you begin listening, adjust
the volume to a comfortable level.
Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a vol-
ume level that does not cause dis-
comfort might still damage your
hearing.
Traffic Safety
Do not use headphones with your re-
ceiver when operating a motor vehicle
or riding a bicycle in or near traffic.
Doing so can create a traffic hazard
and could be illegal in some areas.
If you use headphones with your re-
ceiver, be very careful. Do not listen to
a continuous broadcast. Even though
some headphones let you hear some
outside sounds when listening at nor-
mal volume levels, they still can
present a traffic hazard.
CONNECTING A TAPE
RECORDER
You can connect an optional tape re-
corder to your receiver’s REC LINE
OUT jack to record transmissions.
The recorder must have a line level in-
put jack.
Note: If you use a recorder’s MIC IN
jack to connect to the receiver, the
sound will be distorted.
ST
11
To connect a tape recorder, you need
a mono patch cord (not supplied) with
a 1/8-inch (3.5 mm) plug on both ends.
Your local RadioShack store carries a
wide selection of mono patch cords.
Insert the cord’s plug into the REC
LINE OUT jack on the left side of the
receiver, then connect the other end
of the cord to your tape recorder’s
LINE IN jack.
Follow the instructions provided with
your tape recorder to record transmis-
sions from the receiver.
Note: When you connect a tape re-
corder, the receiver’s built-in speaker
continues to work.
The REC STANDBY jack on the left side
of the receiver lets you record a broad-
cast at a preset time.
To connect a tape recorder to the re-
ceiver’s REC STANDBY jack, you need
a mono patch cord (not supplied) with
a 3/32-inch (2.3 mm) plug. And, your
tape recorder must have a STANDBY
IN or REMOTE IN jack rated at no
more than 20V, 150mA.
Connect one end of the cord to the
REC STANDBY jack, then connect the
other end to your recorder’s STAND-
BY IN or REMOTE IN jack. Then see
“Timer Recording” on Page 33 for
more information about using the re-
ceiver’s timers to record.
USING THE STAND
You can position the receiver more se-
curely and possibly improve the sound
by resting the receiver on its stand.
Lift the latch on the back of the receiver
to open the stand.
12
USING THE MEMO
LABEL
You can use the memo label under the
receiver’s stand to record helpful infor-
mation, such as the memory location
numbers of your favorite stations.
SETTING THE MW (AM)
TUNING INCREMENT
In the United States, the Federal Com-
munications Commission (FCC) as-
signs frequencies for stations in the
MW band in 10-kHz increments. (In the
United States, we commonly call the
MW band the AM band.) In Europe and
some other parts of the world, MW fre-
quencies are assigned in 9-kHz incre-
ments.
MW-STEP on the right side of the re-
ceiver is preset to 10k for use in the
United States, Canada, and many
South American countries. Depending
on the country you are in, you might
have to change the frequency step.
If you are in a country where the AM
frequency increments are 9 kHz, set
MW-STEP to 9k.

tions with weaker signals, use one
of the manual tuning methods.
When scanning in a lower band,
the receiver searches only within
the selected band and stops at the
upper and lower limits of the band.
Your receiver shows the short-
wave bands you can receive on
the bottom of the display.
TUNING
PREPROGRAMMED
SHORTWAVE STATIONS
Your receiver is preprogrammed with
212 of the most popular worldwide
and U.S. shortwave stations. You can
quickly tune these popular stations.
Notes:
You cannot change the preset
shortwave stations stored in your
receiver’s memory.
You can store shortwave frequen-
cies into the receiver’s empty
memory locations. See “Storing
SW Frequencies in Memory” on
Page 28 for more information.
International commercial broad-
cast programs (often in English)
usually contain news, commentar-
ies, music, and special features
reflecting the culture of the broad-
casting country. Reception for this
range is best between 6:00 PM
and midnight (your time).
Follow these steps to tune prepro-
grammed shortwave stations.
1. Find the country and frequency for
the shortwave station you want to
tune in the “DX-398 Shortwave
Pages Chart” on Page 21. Then
write down the page number and
memory location number shown
on the chart for that station.
2. Press SW, then press PAGE.
3. While PAGE is flashing, repeat-
edly press TUNING or TUNING
or turn MANUAL TUNING until
the page number you wrote down
in Step 1 appears next to PAGE.
The name of the broadcaster’s
country also appears next to
PAGE.
Then, when you reach the desired
page number, press ENTER .
4. Press a number key to enter the
memory location number you
wrote down in Step 1. The re-
ceiver tunes the station.
21
Note: If you press a number key for a memory location number where there is no
station stored, MEMOFREE flashes for a few seconds. Then the receiver tunes the
station you previously tuned.

ADJUSTING THE TONE
Set TONE to NEWS to enhance broad-
cast voices while listening to talk
shows or news programs on SW, MW,
and LW frequencies.
Set TONE to MUSIC to enhance treble
and bass response when listening to a
music program (especially FM pro-
grams).
Set
TONE to NORM to help reduce in-
terference.
SPECIAL TUNING
CONTROLS
STEREO/MONO-FM
You can receive FM stereo by con-
necting stereo headphones to the
jack and setting STEREO/ MONO-FM on
the right side of the receiver to STE-
REO.
To improve reception for weak FM ste-
reo stations, set STEREO/MONO-FM to
MONO-FM. The sound is no longer in
stereo, but the reception should im-
prove.
WIDE/NARR.-AM
A strong station that broadcasts close
to a frequency you tuned might inter-
fere with that frequency. To reduce in-
terference from adjacent stations in the
SW, MW, or LW bands, set WIDE/
NARR.-AM
on the right side of the re-
ceiver to NARR.-AM. Or, if there is no
interference, set it to WIDE for better
sound.
AM RF GAIN
25
AM RF GAIN on the left side of the re-
ceiver lets you tune a received signal
for the best SW reception. If the signal
is weak, turn AM RF GAIN toward +. If
the sound is distorted, turn AM RF GAIN
toward –.
TUNING SSB STATIONS
SSB (single sideband) is very popular
among amateur radio and business ra-
dio users because of its superior signal
quality. Many amateurs who operate
SSB and transmit below 10 MHz gen-
erally use LSB (lower sideband), while
amateur and commercial stations who
transmit above 10 MHz generally use
USB (upper sideband). Your receiver
receives both USB and LSB transmis-
sions.
Follow these steps to receive SSB
stations.
1. Select an SW band (see “Select-
ing a Band” on Page 18).
2. If you know the frequency of an
SSB station, enter that frequency.
Or, scan the band for SSB stations
by slowly rotating MANUAL TUN-
ING, tuning through the selected
band until you hear an SSB sta-
tion. Or, scan the band for USB or
LSB stations by holding down
TUNING or TUNING for
about 2 seconds until you hear an
USB or LSB station
Note: SSB stations sound dis-
torted when you tune to them in
the normal SW band. To help you
find SSB stations, watch for
deflections on the signal strength
indicator. Since SSB is transmit-
ted with a suppressed carrier, the
signal strength indicator will move
more quickly when there is a
transmission and more slowly dur-
ing pauses in the transmission.
3. When you have located an SSB
station, press AM MODE to receive
the transmission. Repeatedly
press
AM MODE to switch between
USB or LSB transmissions (try
LSB for frequencies below 10
MHz or USB for frequencies
above 10 MHz).
4. Set STEP to SLOW then readjust
MANUAL TUNING for maximum
intelligibility.
USING RDS
The receiver displays information
about FM radio stations that transmit a
Radio Data System (RDS) signal.
When the receiver receives an RDS
station, the station’s call letters appear
on the display. Also, if the station
broadcasts CT (clock time) informa-
tion, the receiver automatically cor-
rects the displayed time.
26
Follow these steps to use RDS.
1. Turn on the receiver.
2. Tune the receiver to an FM station
that transmits RDS (and CT) infor-
mation.
3. Set TIME SET on the right side of
the receiver to AUTO.
4. Make sure that your local time (as
described in “Setting and Viewing
the Local Time” on Page 16) has
been set correctly. (The receiver
compares the CT information with
your local time to display the cor-
rect time at the broadcaster’s loca-
tion).
5. If your time zone is using Daylight
Saving Time, repeatedly press
until appears.
27
MEMORY FUNCTIONS
Besides tuning to the preprogrammed
shortwave stations (see “Tuning Pre-
programmed Shortwave Stations” on
Page 20), you can store and then
quickly tune up to 94 frequencies in
your receiver’s
memory locations
. The
memory locations are grouped into
pages
(nine memory locations per
page).
You can store up to 18 FM frequen-
cies (2 pages), 18 MW frequencies (2
pages), and 9 LW frequencies (1
page) into your receiver’s FM/MW/LW
memory locations. You can store fre-
quencies automatically (see “Automat-
ic Storage”) or manually (see “Manual
Storage”).
Additionally, you can store frequencies
into any empty memory location in the
receiver’s SW memory pages (see
“Storing SW Frequencies in Memory”
on Page 28). There are 40 empty lo-
cations scattered throughout the pag-
es, and all 9 locations in Page 29 are
blank. See “DX-398 Shortwave Pages
Chart” on Page 21.
STORING FM, MW, OR
LW FREQUENCIES IN
MEMORY
Automatic Storage
You can set your receiver’s automatic
tuning system (ATS) so it automatically
stores all available FM, LW, and MW
stations (from strongest to weakest) in
the FM, LW, and MW memory loca-
tions until all the memory locations are
occupied. This feature helps you find
local stations in another city by simply
pressing a memory location button.
Note: You cannot use this feature to
store SW stations.
To use ATS, hold down ATS/FM, ATS/
LW, or ATS/MW for about 3 seconds.
The receiver beeps and the selected
band and ATS flash. Then the receiv-
er automatically scans and stores the
strongest frequency into the first avail-
able memory location. It continues to
scan and store frequencies until it fills
the nine memory locations in that
page.
The first stored station appears. Once
the receiver has stored nine stations
in Page 1, press PAGE to select the
next page. Then hold down ATS/FM or
ATS/MW again to store the other avail-
able frequencies. The receiver beeps

LISTENING HINTS
Shortwave listening is a hobby with
thousands of participants worldwide. It
requires no special knowledge or
skills, but your enjoyment increases as
you gain experience and develop spe-
cial listening techniques.
The information in this section can help
you make the most of your DX-398.
REFERENCE SOURCES
Many books and magazines about
shortwave listening are available
through your local library or news-
stand. Consult sources such as the
World Radio Handbook
,
Radio Ama-
teur’s Handbook
,
Passport to World
Band Radio
,
Monitoring Times
, and
Popular Communications
. These pub-
lications can help you learn about the
conditions that make long-distance re-
ception possible and provide up-to-
date listings for shortwave broadcasts
in English and in other languages.
FREQUENCY
CONVERSION
A band is a group of frequencies.
Sometimes, bands are grouped ac-
cording to their wavelengths, in
meters. The tuning location of a station
can be expressed as a frequency (kHz
or MHz) or a wavelength (meters).
Amateur radio operators generally re-
fer to the frequencies they operate on
using the frequency’s wavelength. For
example, the 19-meter band refers to
the range of frequencies with waves
about 19 meters long.
Use the following equations to convert
kHz, MHz, and meters.
To convert MHz to kHz, multiply by
1,000. For example:
9.62 MHz × 1000 = 9,620 kHz
To convert kHz to MHz, divide by
1,000. For example:
2780 kHz ÷ 1000 = 2.780 MHz
To convert MHz to meters, divide 300
by the number of MHz. For example:
300 ÷ 7.1 MHz = 42.25 meters
To convert meters to MHz, divide 300
by the number of meters. For exam-
ple:
300
÷ 42.25 meters = 7.1 MHz
BAND ALLOCATION
Certain bands are set aside for specific
purposes.
Amateur Radio Frequencies
Tuning to the amateur radio frequen-
cies can be interesting and helpful, be-
cause amateur radio operators often
broadcast emergency information
when other means of communication
break down.
35
Amateur radio operators use the fol-
lowing bands. Portions of these bands
are set aside for continuous wave
(CW) Morse code communication or

International Frequencies
International commercial broadcasts
are found in the following shortwave
bands. Programs (often in English)
usually contain news, commentaries,
music, and special features reflecting
the culture of the broadcasting country.
Reception for this range is best be-
tween 6:00 PM and midnight (your
time).
*
These bands are reserved for sta-
tions in tropical areas.
**
Interference is heavy in the 41m
band (7.100–7.300 MHz) because am-
ateur radio operators and international
stations share this range.

BIRDIES
Birdies are the products of internally generated signals that make some frequencies
difficult or impossible to receive. If you program a birdie frequency, you hear only
noise on that frequency. The most common birdies to watch for on this receiver are:
Notes:
See “Storing SW Frequencies in Memory” on Page 28 for more information
about using the shortwave page 29.
Interference from devices such as dimmer switches and motors and atmo-
spheric conditions can disrupt shortwave listening. You can minimize interfer-
ence by moving the receiver away from the source of noise, or turning off the
offending device. Shortwave stations sometimes change their operating fre-
quency to avoid interfering with other stations, to improve reception during dif-
ferent seasons, or to take advantage of signal propagation changes due to sun
spots. For this reason, a given station might not be found on the frequency
listed in memory. Reception of these stations can also be affected by rapid
changes in the ionosphere. Sometimes the station you are listening to might
fade out completely. These occurrences are normal shortwave listening condi-
tions.
AMATEUR SHORTWAVE BANDS IN THE US
Amateur radio operators in the U.S.A. are found in the bands listed here. They op-
erate mostly in LSB (Lower Side Band) mode. Morse code operators are generally
found in the lower areas of each band. The amateur radio operators with the most
advanced classification are found in the upper areas of each band.

TROUBLESHOOTING
We do not expect you to have any problems with your receiver, but if you have a
problem, the information in this chart might help. If the problem persists, take the
receiver to your local RadioShack store for assistance.
SYMPTOM POSSIBLE CAUSE SUGGESTION
Weak or intermittent
sound. The internal batteries
are weak. Check the batteries and
replace or recharge
them as necessary.
The antenna must be
adjusted. Adjust the telescoping
antenna or connect an
external antenna.
The signal is blocked by
metal or concrete. Move the receiver near a
window when you use it
inside a vehicle or metal-
frame building.
The frequency is not
tuned properly. Fine-tune the frequen-
cy. See “Tuning Sta-
tions” on Page 18.
Scanning stops on a fre-
quency that has an un-
clear transmission.
The frequency is not
tuned properly. Fine-tune the frequen-
cy. See “Tuning Sta-
tions” on Page 18.
The frequency is one of
the receiver’s birdie fre-
quencies.

CARE AND MAINTENANCE
Your RadioShack DX-398 All-Band Shortwave Receiver with Radio Data
System is an example of superior design and craftsmanship. The following
suggestions will help you care for your receiver so you can enjoy it for years.
Keep the receiver dry. If it gets wet, wipe it dry immediately. Liq-
uids might contain minerals that can corrode the electronic cir-
cuits.
Use and store the receiver only in normal temperature environ-
ments. Temperature extremes can shorten the life of electronic
devices, damage batteries, and distort or melt plastic parts.
Keep the receiver away from dust and dirt, which can cause pre-
mature wear of parts.
Handle the receiver gently and carefully. Dropping it can damage
circuit boards and cases and can cause the receiver to work im-
properly.
Use only fresh batteries of the required size and recommended
type. Batteries can leak chemicals that damage your receiver’s
electronic parts.
Wipe the receiver with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong de-
tergents to clean the receiver.
Modifying or tampering with the receiver’s internal components can cause a
malfunction and might invalidate its warranty and void your FCC authoriza-
tion to operate it. If your receiver is not performing as it should, take it to your
local RadioShack store for assistance.
45
RESETTING THE
DISPLAY
If the display shows random charac-
ters or does not work properly, you
might need to reset it.
Important: This procedure clears the
set time and resets the receiver’s mi-
croprocessor (the component that
controls how the receiver operates),
but all stations remain stored. Reset
the receiver only when you are sure it
is not working properly.
To reset the display, insert a pointed
object, such as a straightened paper
clip, into the RESET hole on the bot-
tom of the receiver. Then gently press
and release the button inside the hole.
