DX-398

All-Band Shortwave Receiver

with Radio Data System

FEATURES

Your RadioShack DX-398 All-Band Shortwave Receiver with Radio Data System brings you the voices of the world. In the 14 international shortwave (SW) bands, you can hear news broadcasts and other programs from sources around the world, such as the British Broadcasting Corporation, Radio 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 sometimes 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 directly record your favorite programs live or at a preset time.

Your receiver’s features include:

Large, Fast-Response Display

— shows the time, band and frequency, signal strength, and other indicators.

212 Preprogrammed Shortwave Stations —

let you rapidly tune to the most popular U.S. and international shortwave stations.

Three Timer Alarms

— let you set the buzzer to sound or the radio to turn on daily at up to three specified times.

Record Line Out and Standby Jacks

— let you connect a tape recorder so you can record broadcasts live or at a preset time.

For private listening and for stereo sound during FM stereo broadcasts, you can plug optional stereo headphones with a (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, appears on the display.

/8-inch (3.5 mm) plug

• Once you set the volume, do not increase it. Over time, your ears adapt to the volume le vel, 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.

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.

CONNECTING A TAPE RECORDER

You can connect an optional tape recorder to your receiver’s

jack to record transmissions.

OUT

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.

REC LINE

To connect a tape recorder, you need a mono patch cord (not supplied) with

/8-inch (3.5 mm) plug on both ends. Your local RadioShack store ca rries a wide selection of mono patch cords.

Insert the cord’s plug into the

LINE OUT

jack on the left side of the

REC

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.

Connect one end of the cord to the

REC STANDBY

jack, then connect the other end to your recorder’s STANDBY 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.

REC ST ANDBY

The

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

/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.

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-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 frequencies are assigned in 9-kHz increments.

If you are in a country where the AM frequency increments are 9 kHz, set

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.

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.

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.

MEMORY FUNCTIONS

Besides tuning to the preprogrammed shortwave stations (see “Tuning Preprogrammed Shortwave Stations” on Page 20), you can store and then quickly tune up to 94 frequencies in your receiver’s 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 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.

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 newsstand. Consult sources such as the

World Radio Handbook, Radio Amateur’s Handbook Band Radio Popular Communications

lications can help you learn about the conditions that make long-distance reception possible and provide up-todate listings for shortwave broadcasts in English and in other languages.

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 example:

300 ÷ 42.25 meters = 7.1 MHz

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

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:

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 co untry. Reception for this range is best between 6:00 PM and midnight (your time).

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

These bands are reserved for sta-

tions in tropical areas.

Frequency

Range

(in MHz)

Interference is heavy in the 41m band (7.100–7.300 MHz) because amateur radio operators and international stations share this range.

Aircraft Frequencies

Time Standard Frequencies

Aircraft on international routes sometimes use SW. Most transmissions are in SSB, although you can still hear some MW transmissions. Here are some bands where you might hear aircraft communications.

4,650–4,750 kHz 6,545–6,765 kHz 8,815–9,040 kHz 11,175–11,400 kHz 13,200–13,360 kHz 15,010–15,100 kHz 17,900–18,030 kHz

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.

2,000–2,300 kHz 4,063–4,139 kHz 4,361–4,438 kHz 8,195–8,181 kHz 12,330–12,420 kHz 13,107–13,200 kHz 16,460–16,565 kHz

The Coast Guard and small boats use this band, with 2,182 kHz set aside as the international distress and emergency channel.

The following frequencies announce the exact time of day at specified intervals.

WWV in Fort Collins, Colorado:

2,500 kHz 5,000 kHz 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 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 stations throughout North America. However, re cept ion varie s b ased on t h e seaso n, tim e of day, and a number of other conditions.

BIRDIES

Birdies are the products of internally generated signals that make some fre quencies difficult or impossible to receive. If you program a birdie frequency, you hear only noise on that frequency. The most common birdies to watch f or on this receiver ar e:

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 migh t fade out completely. These occurrences are normal shortwave listening conditions.

AMATEUR SHORTWAVE BANDS IN THE US

Amateur radio operators in the U.S.A. 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.

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 ge ts wet, wipe it dry immediately. L iquids 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 rece iver’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:

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 s ure it is not working properly.

To reset the display, insert a pointed object, such as a straightened paper clip, into the tom of the receiver. Then gently press and release the button inside the hole.

This procedure clears the
