PREPARATION
CONNECTING TO POWER
You can power the receiver from internal 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 batteries.
1. Remove the battery compartment'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 (PLUS and
MINUS)
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 disconnects internal batteries.
Caution: You must use a Class 2 power source that supplies
6
volts DC and delivers 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 recommended adapter meets these specifications.
Using
an adapter that does not meet these specifications could damage
the receiver or the adapter.
When you finish using the AC adapter, unplug it from the
AC
outlet 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 diameter/ 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
vehicle'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 delivers 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 recommended DC cigarette lighter adapter meets
these specifications. Using an adapter that does not meet
these
specifications could damage the receiver or the adapter.
Caution: Always plug the DC cigarette lighter adapter into
the
receiver before you plug it into your vehicle's cigarette-
lighter socket. Always unplug the adapter from the vehicle's
cigarette-lighter socket before you unplug it from the
receiver.
Follow these steps to power the receiver from your vehicle's
battery.
1. Set the DC cigarette lighter adapter's voltage switch
to 6V.
2. Insert the adapter's 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 telescoping 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 receiver. The receiver
uses a built-
in antenna 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) directly to the
AM
EXT ANT jack on the left side of the receiver. This
automatically disconnects the receiver's built-in antenna.
Follow the antenna's supplied instructions to connect it
to the
receiver.
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 disconnects the internal speaker.
When you connect stereo headphones and tune to a stereo
broadcast, HEADPHONES 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-
volume listening can lead to permanent hearing loss.
° Set the volume to the lowest setting 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 volume level that does
not
cause discomfort might still damage your hearing.
Traffic Safety Do not use headphones with your receiver 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 receiver, be very careful.
Do
not listen to a continuous broadcast. Even though some
headphones let you hear some outside sounds when listening
at
normal volume levels, they still can present a traffic hazard.
CONNECTING A TAPE RECORDER
You can connect an optional tape recorder to your receiver's
REC
LINE OUT jack to record transmissions.
The recorder must have a line level input jack.
Note: If you use a recorder's MIC IN jack to connect to the
receiver, the sound will be distorted.
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 transmissions from the receiver.
Note: When you connect a tape recorder, the receiver's built-in
speaker continues to work.
The REC STANDBY jack on the left side of the receiver lets
you
record a broadcast at a preset time.
To connect a tape recorder to the receiver'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 receiver's timers to record.
USING THE STAND
You can position the receiver more securely 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.
USING THE MEMO LABEL
You can use the memo label under the receiver's stand to
record
helpful information, such as the memory location numbers of
your favorite stations.
SETTING THE MW (AM) TUNING INCREMENT
In the United States, the Federal Communications Commission
(FCC) assigns frequencies for stations in the MW band in 10-xkHz
increments. (In the United States, we commonly call the MW
band
the AM band.) In Europe and some other parts of the world,
MW
frequencies are assigned in 9-kHz increments.
MW-STEP
on the right side of the receiver 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.

ADJUSTING THE TONE Set TONE to NEWS to enhance broadcast
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 programs).
Set TONE to NORM to help reduce interference.
SPECIAL TUNING CONTROLS
STEREO/ MONO-FM
You can receive FM stereo by connecting stereo headphones
to the
jack and setting STEREO/ MONO-FM on the right side of the
receiver to STEREO.
To improve reception for weak FM stereo stations, set STEREO/
MONO-FM to MONO-FM. The sound is no longer in stereo, but
the
reception should improve.
WIDE/ NARR.-AM
A strong station that broadcasts close to a frequency you
tuned
might interfere with that frequency. To reduce interference
from adjacent stations in the SW, MW, or LW bands, set WIDE/
NARR.-AM on the right side of the receiver to NARR.-AM. Or,
if
there is no interference, set it to WIDE for better sound.
AM RF GAIN
AM RF GAIN on the left side of the receiver lets you tune
a
received signal for the best SW reception. If the signal is
weak, turn AM RF GAIN toward Plus. If the sound is distorted,
turn AM RF GAIN toward Minus.
TUNING SSB STATIONS SSB (single sideband) is very popular
among
amateur radio and business radio users because of its superior
signal quality. Many amateurs who operate SSB and transmit
below 10 MHz generally 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
transmissions.
Follow these steps to receive SSB stations.
1. Select an SW band (see "Selecting 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
TUNING, tuning through the selected band until you hear an
SSB
station. Or, scan the band for USB or LSB stations by holding
down TUNING up or TUNING down for about 2 seconds until you
hear
an USB or LSB station
Note: SSB stations sound distorted 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
transmitted with a suppressed carrier, the signal strength
indicator will move more quickly when there is a transmission
and more slowly during 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) information, the receiver automatically corrects
the displayed time.
Follow these steps to use RDS.
1. Turn on the receiver.
2. Tune the receiver to an FM station that transmits RDS
(and
CT) information.
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 correct time at the broadcaster's location).
5. If your time zone is using Daylight Saving Time, repeatedly
press TIME SET until SUN appears.
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 frequencies (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
frequencies automatically (see "Automatic 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
locations
scattered throughout the pages, 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 locations 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 receiver automatically scans and stores the
strongest frequency into the first available 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
available frequencies. The receiver beeps when it finishes
automatically tuning stations.
Manual Storage 1. Press ATS/ FM, ATS/ MW, or ATS/ LW to select
the band where you want to store a frequency.
2. Tune to the frequency you want to store.
3. Repeatedly press PAGE to select the page where you want

Notes: ° PAGE flashes only when the receiver is set to
SW mode.
If you wait more than 10 seconds to press PAGE, PAGE stops
flashing.
If you pressed ATS/ LW in Step 1, PAGE does not appear because
there is only one LW page.
4. Press M/ MEM. MEMO flashes for about 12 seconds. The number
for the first available empty memory location for the selected
page flashes next to MEMO.
Note: If an empty memory location number does not flash,
all
memory locations are full in the band you selected. If this
happens, clear a memory location (see "Deleting a Station
You
Stored" on Page 30) then store the frequency. Or, to
replace a
stored frequency with a new frequency, repeatedly press TUNING
UP or DOWN to select a new frequency, press M/ MEM, then press
the number key for the memory location. After a few seconds,
the
receiver beeps and stores the new frequency in the memory
location.
5. Press ENTER to store the frequency in the flashing memory
location. The receiver beeps and a bracket appears around
the
memory location number where you stored the frequency, to
show
that the frequency was stored there.
STORING SW FREQUENCIES IN MEMORY
Follow these steps to store shortwave frequencies into empty
memory locations in the shortwave page.
1. Press METER/ SW to select the shortwave band.
2. Tune to the frequency you want to store. The currently

or down,
PAGE and MEMO stop flashing. If this happens, start again
at
Step 3.
5. Press ENTER to assign the frequency to the flashing memory
location. The receiver beeps and a bracket appears around
the
number where you stored the frequency.
Notes: ° If the receiver's memory is full, MEMOFULL appears
when you press a number key.
° To replace a frequency you stored with a new frequency,
repeatedly press TUNING up or TUNING down to select a new
frequency, press M/ MEM, then hold down the number key
corresponding to that memory location for about 2 seconds.
The
receiver beeps and stores the new frequency in the memory
location.
ASSIGNING A NAME TO AN FM/ MW/ LW STATION OR SW PAGE
To help you easily identify stored frequencies, you can assign
a
name (up to 8 characters) to an FM, MW, or LW memory location,
or to an SW page.
1. Select a band (see "Selecting a Band" on Page
18).
2. Repeatedly press PAGE to select the page number where

.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 special 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
Amateur's Handbook, Passport to World Band Radio, Monitoring
Times, and Popular Communications. These publications can
help
you learn about the conditions that make long-distance reception
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
according 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 refer 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 times 1000 equals 9,620 kHz
To convert kHz to MHz, divide by 1,000. For example:
2780 kHz divided by 1000 equals 2.780 MHz
To convert MHz to meters, divide 300 by the number of MHz.
For
example:
300 divided by 7.1 MHz equals 42.25 meters
To convert meters to MHz, divide 300 by the number of meters.
For example:
300 divided by 42.25 meters equals 7.1 MHz
BAND ALLOCATION Certain bands are set aside for specific
purposes.
Amateur Radio Frequencies Tuning to the amateur radio
frequencies can be interesting and helpful, because amateur
radio operators often broadcast emergency information when
other means of communication break down.
Amateur radio operators use the following bands. Portions
of
these bands are set aside for continuous wave (CW) Morse code
communication or for single sideband (SSB) voice communication,
as shown below.
160 meters: 1,800 2,000 kHz: SSB
80 meters: 3,500 3,800 kHz: CW 3,800 4,000 kHz: SSB
40 meters: 7,000 7,150 kHz: CW 7,150 7,300 kHz: SSB
20 meters: 14,000 14,200 kHz: CW 14,200 14,350 kHz: SSB
15 meters: 21,000 21,250 kHz: CW 21,250 21,450 kHz: SSB
10 meters: 28,000 28,500 kHz: CW 28,500 29,700 kHz: SSB
Note: These ranges are not precisely observed everywhere
in the
world.
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 between 6: 00 PM and midnight
(your time).
* These bands are reserved for stations in tropical areas.
** Interference is heavy in the 41meter band (7.100–
7.300 MHz)
because amateur radio operators and international stations
share this range.

10,000 kHz
15,000 kHz
20,000 kHz
CHU in Canada:
7,335 kHz
VNG in Australia:
4,500 and 12,000 kHz
Longwave Band The 150– 519 kHz range is known as the
longwave
band. Most stations in this range serve as beacons for aircraft
and marine navigation by continuously transmitting their call
letters. Reception for this range is best between 6: 00 PM
and
midnight (your time).
Some ships also use this range, with 500 kHz set aside as
an
international distress and emergency station.
Most stations in this range use CW (Morse code), although
some
use A M voice transmission for weather broadcasts.
LISTENING GUIDE The following list contains some of the more
frequently heard stations. All stations broadcast in English
unless otherwise specified. You can hear these stations
throughout North America. However, reception varies based
on the
season, time of day, and a number of other conditions.
This information can change at any time. For sources of yearly,

.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:
450 kHz 3,844 kHz 9,000 kHz 10,250 kHz 18,000 kHz 20,490
kHz
21,835 kHz 21,868 kHz
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 atmospheric conditions can disrupt shortwave listening.
You
can minimize interference by moving the receiver away from
the
source of noise, or turning off the offending device. Shortwave
stations sometimes change their operating frequency to avoid
interfering with other stations, to improve reception during
different 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 conditions.
AMATEUR SHORTWAVE BANDS IN THE US Amateur radio operators
in the
United States of America are found in the bands listed here.
They
operate 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 frequency.
See "Tuning Stations" on Page 18.
Scanning stops on a frequency that has an un-clear transmission.
The frequency is not tuned properly. Fine-tune the frequency.
See "Tuning Stations" on Page 18.
The frequency is one of the receiver's birdie frequencies.
Tune another frequency.
Frequency does not change when you turn ROTARY TUNING.
FAST/ SLOW/ STOP is set to STOP. Set FAST/ SLOW/ STOP to
FAST
or SLOW.
ROTARY TUNING and front panel buttons do not respond.
The keypad is locked KEY appears on the display).
Press the lock button.
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.
Liquids might contain minerals that can corrode the electronic
circuits.
Use and store the receiver only in normal temperature
environments. 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
premature wear of parts.
Handle the receiver gently and carefully. Dropping it can
damage
circuit boards and cases and can cause the receiver to work
improperly.
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 detergents 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 authorization to operate it. If your receiver
is
not performing as it should, take it to your local RadioShack
store for assistance.
RESETTING THE DISPLAY
If the display shows random characters or does not work
properly, you might need to reset it.
Important: This procedure clears the set time and resets
the
receiver's microprocessor (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 bottom
of
the receiver. Then gently press and release the button inside
the hole.
