Your Radio Shack DX-392 PLL AllBand Portable R eceiver with Cassette
Recorder brings the voices of the world
to you. In the 13 international shortwave (SW) bands, you can hear news
broadcasts and other programs from
sources such as the British Broadcasting Company, Radio Cairo, and Radio
Moscow.
You can get emergency information
firsthand by listening to amateur radio
broadcasts, which include single sid eband (SSB) voice transmissions and
continuous wave (CW) Morse code
transmissions.
In the longwave (LW) band, you
sometimes hear hurricane reports,
ship-to-shore calls, and other marine
and aeronautical services. You can
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 use the built-in cassette recorder to record your favorite programs live or at a preset time.
Special features include:

In the United States, the Federal Communications Commission (FCC) assigns frequencies for stations in the
MW band in 10-kilohertz 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-kilohertz increments.

USING THE CLOCK RADIO
Your receiver has t wo clocks. We recommend you set the primary clock for
local time and the secondary c lock for
UTC (Coordinated Universal Time —
formerly called Greenwich Mean
Time), because most shortwave stations announce broadcast times in
UTC.
The time zone ma p on the back o f the
receiver shows the difference in hours
between UTC and each time zone. To
determine your local time, tune your
receiver to a time standard frequency
(see “Time Standard Frequencies” on
Page 24) and get the current UTC
time. Then ad d or subtract the specified number of hours f rom UTC time.

Listening Safely
To protect your hearing, follow these
guidelines when you use headphones.
• Set the volume to the l owest setting before you begin listening.
After you begin listening, adjust
the volume to a comfortable level.
• Do not listen at extremely high
volume levels. Extended highvolume listening can lead to permanent hearing loss.
• 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.

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).
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 sp ecial listening techniques.
The information in this section can help
you make the most of your DX-392.
22
Amateur radio operators generally refer to the frequencies they operate on
using the freq uency ’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 ³ 1000 = 2.780 MHz
3,800–4,000 kHz: SSB
To convert MHz to meters, divide 300
by the number of MHz. For example:
300 ³ 7.1 MHz = 42.25 meters
To convert meters to MHz, divide 300
by the number of meters. For example:
300 ³ 42.25 meters = 7.1 MHz
BAND ALLOCATIONS
Certain bands are set aside for specific
purposes.
Amateur Radio Frequencies
Tuning to the amateur radio freque ncies can be interesting and helpful, because amateur radio operators often
broadcast emergency information
when other means of communication
break down.
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
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
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-
Interference is heavy in the 41m
band (7.100–7.300 MHz) because amateur radio operators and international
stations share this range.
7.100–7.350
Aircraft Frequencies
Aircraft on international routes sometimes use SW. Most transmissions are
in SSB, although you can still hear
some AM transmissions. Here are
some bands where you might hear aircraft communications.
Ships and Coastal Station
Frequencies
Most transmissions from ships and
coastal stations are in SSB and CW.
You can hear these transmissions in
the following bands.
The Coast Guard and small boats
use this band, with 2,182 kHz set aside
as the international distress and emergency channel.

CHU in Canada: 7,335 kHz
VNG in Australia: 4,500 and
12,000 kHz
Longw ave 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 AM
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 sta tions throughout North America. However, reception varies based on t he season, time
of day, and a number of other conditions.
This information can change at any
time. For sources of yearly, up-to-date
listings, see “Reference Sources” on

BIRDIES
Birdies are the products of int ernally generated signals that make s ome frequencies
difficult or impossible to receive. If you program one of these frequencies, you hear
only noise on that frequency. The most common birdies to watch for are listed below.
The following suggestions will help you get the best performance from your cassettes and cassett e deck.
STORING YOUR CASSETTES
• Keep them away from excessive dust and dirt.
• Do not expose them to moisture or high humidity.
• Keep them away from strong magnetic fields that can be generated by other
electronic devices (transformers, motors, and so on).
• Store them in pr otective plasti c cont ainers. Your local Radio Shack store offers a
complete selection of tape storage containers.
ERASING TAP ES
Each time you record on a cassette tape, the previous recordin g is automatically
erased.
If you want to erase a tape without making a new recording, load the tape into the
casse tte compartm ent and press
tape passes the record head. If you want to quickly erase a tape , you might prefer
to use a bulk tape eraser, availab le at your l ocal Radio Shack store. It erases both
sides of an entire tape in a few seconds.

record. Be sure to p lace the radio in a quiet a re a if you want to erase a tape by recording over it.
ACCIDENTAL ERASURE PREVENTION
All cassettes have erase-protection tabs . When in pla ce, these tabs let you record
on the tape. Once you remove these tabs, you cannot press

driver. If you wish to protect Side B (or 2), remove the Side B (or 2) tab.
To record on the tape again, place a piece of strong plastic tape over the erase-pro-
tection tab holes.
Note: Removal of the erase-protection tab does not prevent a bulk eraser from erasing the tape.
Caution: When using a cassette that has had the erase-protection tabs broken off,
do not try to force down

TAPE TENSION
After you play a cassette tape several times, the tape might become tightly wound
on the reels. This can cause playback sound quality to deteriorate.
To restore the sound quality, fast-forward the tape from the beginnin g to the end of
one side, then completely rewind it. Then loosen the tape reels by gently tapping
each side of the cassette’s outer shell on a flat surface.
Caution: Be careful not to damage the casset te when tappi ng it. Do not touc h the
exposed tape or allow any sharp objects near the cassette.
33
CLEANING THE TAPE MECHANISM
After repeated use, dust, lint and tape
oxides accumulate on the tape-handling mechanisms. For the best performance and sound quality, clean the
record/play heads, pinch rollers, ca pstans, and erase head after approximately every 20 hours of use. You can
use recorder cleaner and cleaning
swabs or a convenient head-cleaner
cassette. All these cleaning products
are available at your local Radio Shack
store.

MAINTENANCE
CARING FOR THE
RECEIVER
Your Radio Shack DX-392 PLL AllBand Portable R eceiver with Cassette
Recorder 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.
Use only fresh batteries of
the recommended size and
type. Never leave dead or
weak batteries in the receiver. They might leak
chemicals that can damage
the receiver.
Keep the receiver d ry. If it
gets wet, wipe it dry immediately. Liquids can contain
minerals that can corrode
the electronic circuits.
Handle the receiver gently
and carefully. Dropping it
can damage circuit boards
and can cause the receiver
to work improperly.
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 your receiver.
Modifying or tampering with your receiver’s internal components can
cause a malfunction and might invalidate the receiver’s warranty and void
your FCC authorization to op erate the
receiver. If your receiver is not performing as it should, take it t o your local Radio Shack store for assistance.
THE FCC WANTS YOU
TO KNOW
Your receiver might cause interference
on other radio/TV devices even when it
is operating properly. To determine
whether your receiver is causing the
interference, turn off your receiver. If
the interference goes away, your receiver is causing it.
Use and store the receiver
only in normal t emperature
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 we ar
of parts.
Try to eliminate the interference by:
• Moving your receiver away from
the other device.
• Connecting your receiver to an
outlet that is on a different electr ical circuit from the other device.
• Contacting your local Radio
Shack store for help.
