HOW TO USE THE INCLUDED  
“REEL” ANTENNA AND THE  
EXTERNAL ANTENNA SOCKET  
(left side of the radio)  
Install six AA alkaline batteries. Follow the diagram  
imprinted on the back of the radio near the battery  
compartment. With the radio face down and the  
battery compartment toward you:  
If you do not live in the United States or  
Canada, the radio is set up at the factory for  
the 9 kilohertz spacing used for your AM  
(MW) stations. This part of the initial setup  
can be ignored.  
1. On the right side of the radio, set the SSB switch  
to the OFF position. This feature is described on  
page 24. NOTE: the FINE TUNING control, on  
the right side of the radio, is only activated and  
needed when the G4000A is in the SSB mode.  
You do not need to use this control when listening  
to regular AM, FM, and shortwave broadcasts.  
The SW EXT. ANT. Socket is for shortwave antennas.  
Use it with the included “reel” antenna. Always  
fully unroll the “reel” antenna and place it as high  
off the floor as possible, next to the windows.  
• The flat ends (-) of the bottom batteries go  
toward the left.  
North America’s AM stations are exactly 10 kilohertz  
apart. At the factory, the radio is set up for the 9  
kilohertz spacing of stations in Europe. To change  
this to the 10KHZ spacing:  
• The flat ends (-) of the top batteries go toward  
the right.  
PROFESSIONALLY ENGINEERED  
ANTENNAS  
On the left side of the radio, set the DX/LOCAL  
switch to the DX position. DX allows for maximum  
sensitivity, the preferred position.  
AC ADAPTOR USE  
Professionally engineered, outdoor shortwave  
antennas, available through specialized retailers,  
can also be used. Use the SW. EXT. ANT. Socket  
mentioned above. The socket is a 1/8 inch mono  
socket, used in conjunction with a 1/8 inch mono  
plug, such as the plugs often used for mono ear-  
phones. If you would like advice about shortwave  
antennas, please call Etón technical support at  
1-800-872-2228 for U.S. and 1-800-637-1648  
for Canada.  
1. With the radio OFF, press and release the AM  
button once.  
The Grundig adaptor supplied with this product is  
only for use in the Americas, where household AC  
voltage is 110-120 volts AC. Do not use this adap-  
tor in countries with household AC voltage of 220-  
240 volts AC.  
2. Immediately press and release the STEP button.  
“10 KHz” now appears in the right side of the  
display and will disappear in a few seconds.  
This change will be permanently in the radio’s memory  
as long as batteries are not taken out for a period of  
ten minutes or more.  
USING YOUR GRUNDIG AC  
ADAPTOR  
When traveling outside of the Americas, use the  
same procedure as above to set the spacing back  
to 9 kilohertz.  
1. Plug the adaptor into a household outlet.  
2. Insert plug into the radio’s DC 9 V socket.  
NOTE: when using the adaptor, it is OK to leave  
batteries in the radio.

DIRECT FREQUENCY ENTRY  
If you know the exact frequency of the station  
you want to hear, directly enter it using the keypad  
and immediately press the FREQU./METER button.  
Pressing the FREQU./METER button finalizes the  
entry. Be sure to include the decimal point in FM  
frequencies. Any kind of frequency may be entered  
regardless of what kind of frequency you are  
presently tuned to, e.g. you can enter an FM  
frequency even if you are presently in shortwave.  
Experiment with this switch and let your ears be your  
guide. WIDE gives the best audio fidelity; NARROW  
best minimizes interference from other nearby stations.  
This switch is used for AM, shortwave, and longwave  
listening.  
Press the ON/OFF button.  
For true stereo reproduction in FM, select STEREO  
when you use earphones or headphones. When  
STEREO is selected, and the broadcast is in stereo,  
two circles appear above and to the right of the  
frequency in the display. Use the MONO position  
whenver reception is poor or marginal.

When you want to listen to your radio, press LOCK  
and then the ON/OFF switch.  
In AM (MW), SW, and LW (see below), the STEP  
button provides selection of the best tuning steps,  
in kilohertz. This button is not functional in FM. The  
tuning step rate is indicated in the lower right of  
the display, e.g. “STEP 5”. Use these guidelines:  
If you already know the specific frequency of a  
shortwave station, enter it, using the direct frequency  
entry technique described earlier. For a complete list  
of shortwave frequencies, use the major shortwave  
publications mentioned on page 23.  
G4000A shows the frequency range for each band.

LAST STATION MEMORY FEATURE  
• AM (MW): 10 KHz in the Americas; 9 KHz  
outside of the Americas  
Even if you do not know any specific frequencies of  
shortwave stations, you can find them by going into  
a shortwave band and tuning around, as described  
below.  
EXAMPLE: To enter the 25 meter band:  
Pressing the AM button over and over steps  
through the last station tuned in MW, SW and LW.  
• LW (longwave): 9 KHz for broadcast stations.  
Note: You will probably not hear any stations in  
the Americas, as LW is not used for broadcast  
stations. It is used in Europe and other parts of  
the world for broadcasts to those areas.

HOW TO TUNE AROUND IN A  
SHORTWAVE BAND  
WHAT IS A SHORTWAVE BAND  
• SSB: 1KHz  
Use this to control the loudness of the radio.  
If you have ever listened to AM or FM radio, then  
you already know what a band is. The AM band is  
530-1600 KHz; the FM band is 88-108 MHz. A  
band is simply a frequency range where stations are  
located. When you look for stations in these  
“bands”, you simply tune around until you find a  
station you like. Shortwave is similar, and the short-  
wave bands have names like 25 meters, 31 meters,  
49 meters, etc. These are abbreviated 25m, 31m  
and 49m. Just like in AM and FM radio, one simply  
gets into the shortwave band and tunes around,  
looking for stations.  
AUTO TUNING: The radio will find stations for you  
within the shortwave band you have entered. In  
shortwave, this feature only works within the short-  
wave bands shown on the back of the radio (see  
the chart titled “SHORTWAVE BAND AUTO TUNING  
RANGES”).  
HOW TO USE THE LOCK BUTTON  
HOW AND WHEN TO USE THE  
RESET FEATURE  
When lock is on, the word LOCK appears in the  
upper right area of the display. Using this feature  
has no effect on alarm functions.  
If the radio operates erratically, gently poke an  
opened paper clip into the RESET hole on the front  
of the radio. Normal operation may be restored.  
Note that this procedure erases all memories and  
resets the clock  
When the radio is on: Pressing the LOCK button  
locks all keys except the ON/OFF button and the  
SNOOZE button.

Listed below are the characteristics of the major  
shortwave bands. Follow these guidelines for best  
listening results. Because shortwave signals depend  
on such factors as the sun, the ionosphere and the  
earth itself, signals cannot be heard on all bands  
throughout the day. Some bands are best during  
the daylight hours, and some are best at night.

America. These bands may be extremely good  
around sunset and sunrise too. Best bands are  
BOLD.  
Shortwave listening is generally at its poorest during  
the daylight hours of about 10 a.m. to 3 p.m. The  
major reason for this is that the broadcasters are  
not transmitting to North America at thistime. They  
assume that we are all either at work or at school,  
and are not able to listen during the day. If you  
want to try daytime listening, use the guidelines  
below. You will have some success, but not nearly  
as good as during the late afternoon and evenings.  
The best bands are BOLD.

The construction materials of some buildings simply  
do not let signals in very well. Signals penetrate  
wood frame buildings easiest, while concrete and  
brick buildings usually block signals. If you are in a  
building with one or more stories above you, signals  
can also be impaired in strength. In such a situation,  
position yourself, and especially the radio’s antenna,  
as close to a window as possible while listening.  
Below is a list of the shortwave bands used for  
international broadcasts and their corresponding  
frequencies. Since some radios show frequency in  
megahertz and some in kilohertz, both are shown  
here. The G4000A shows shortwave frequencies  
in kilohertz.

The next chart shows some of the countries targeting  
North America with their broadcasts. Unless otherwise  
noted, frequencies are for evening listening in North  
America. Other countries do not deliberately target  
North America, but can be heard anyway. Whether or  
not a country can be heard depends on many factors,  
including signal strength, your geographic location,  
and the condition of the earth’s ionosphere.

ARE THE SIGNALS CLEAR?  
WHAT ELSE CAN AND CANNOT  
BE HEARD ON SHORTWAVE?  
HOW IS IT THAT BROADCASTS  
FROM AROUND THE WORLD  
CAN BE HEARD ON A SHORT-  
WAVE RADIO?  
Often, but not always. Today’s technology has greatly  
minimized the fading, static and interference that are  
natural aspects of international broadcast listening.  
You can hear long distance two-way marine, aviation,  
and amateur radio (ham). To receive such communica-  
tions, an advanced shortwave receiver with single  
sideband (SSB) capability must be used. The more  
advanced Grundig radios can do this. Local VHF/UHF air  
traffic, police, fire, ambulance, and weather services  
CANNOT be heard. For these, use a VHF/UHF scanner.  
Shortwave radio can be heard around the world  
because of the earth’s ionosphere. Think of the  
ionosphere as a cloud-like layer enshrouding the  
earth at an altitude of 140-250 kilometers (90-160)  
miles). It consists of electrons and ions, the density  
of which are governed by the sun and the earth’s  
geomagnetic forces. Radio waves virtually bounce  
their way around the earth, bouncing off the  
ionoshpere, back down to earth, often repeating  
this process several times. The low angles at which  
this takes place enable the radio waves to travel  
great distances with each bounce. This whole  
process is called radio wave deflection and ionos-  
pheric propagation.  
IS THERE ENGLISH LANGUAGE  
PROGRAMMING?  
CAN I HEAR A SPECIFIC  
COUNTRY?  
Yes! Many major international broadcasters  
incorporate English programming.  
Yes, if that country is transmitting its signal specifically  
for listening in your part of the world. Otherwise,  
it may range from good to impossible.  
CAN DISTANT AM/FM BROAD-  
CAST STATIONS BE RECEIVED?  
WHAT IS THE PROGRAM  
CONTENT LIKE?  
IF A COUNTRY IS NOT  
FM is strictly for local stations. Daytime AM stations  
usually have a maximum distance of 50-100 miles. At  
night, AM broadcast signals can sometimes be heard  
over much greater distances, hundreds of miles away.  
This can vary considerably from country to country;  
however, programming usually consists of world  
news, local news from the country of origin, news  
commentary, interview programs, culturally oriented

TRANSMITTING ITS SIGNAL  
SPECIFICALLY FOR RECEPTION  
IN NORTH AMERICA, IS THERE  
ANY CHANCE OF RECEIVING IT?  
Yes, with detailed research into broadcast time and  
frequency and patience, it is possible but never  
guaranteed. A professionally engineered outdoor  
antenna can make a major difference. Call Grundig  
technical support for advice on such antennas.

HOW CAN I DETERMINE IF  
AN OUTDOOR ANTENNA WILL  
HELP?  
Just what is UTC? It is the time in Greenwich  
England with no correction for daylight savings  
time, and is always stated in 24 hour format. In  
North America, UTC is ahead of our local time, 5  
hours EST, 6 hours CST, 7 hours MST, 8 hours PST;  
one hour less during the months of daylight savings  
time. So, if a broadcast starts at 20:00 hours UTC,  
this correlates to 15:00 hours (or 3PM) Eastern  
Standard Time, and 12:00 hours (Noon) Pacific  
Standard Time.

While inside your normal listening environment, tune  
in a relatively weak shortwave signal. Staying tuned  
to this signal, step outside and away from your  
building. If the signal strength increases significantly,  
an outdoor antenna will help considerably. If there is  
little or no improvement in signal strength, an outdoor  
antenna will help; however, the amount of improve-  
ment will depend on the type of antenna used. If you  
have questions about outdoor antennas, call Grundig  
technical support.

Published annually in early September.  
To determine Coordinated Universal Time, tune-in  
to a major station, such as BBC London, on the  
hour. If your shortwave radio tunes to the following  
frequencies, UTC can be heard each minute on  
station WWV in Fort Collins Colorado: 20000 KHz,  
15000 KHz, 10000 KHz, 5000 KHz and 2500 KHz.  
Usually, during any time of the day, one or more of  
these frequencies can be received in North America.  
UTC can also be heard on the Canadian station  
CHU, at 3330 KHz, 7335 KHz, and 14670 KHz.

High end shortwave radios, such as the Grundig  
G4000A, have a feature called SSB, a highly efficient  
way of electronically processing transmitted and  
received signals for two-way communication.  
HOW TO TURN THE SSB  
FEATURE ON  
Below are some selected frequency ranges on which  
SSB communication can be found. All frequencies  
are shown in Kilohertz.  
1. Slide the SSB switch (right side of radio) to the  
Examples of this are amateur radio (hams), maritime,  
and aeronautical communication. Either upper side  
band (USB) or lower side band (LSB) can be used.  
ON position.  
2. Use the STEP button to select 1 KHz tuning  
steps. “STEP 1” will display in the lower right  
of the display.  
AMATEUR RADIO  
AERONAUTICAL (usually USB) MARITIME (usually USB)  
Receiving SSB signals is not always easy. Since  
this is two-way communication, transmissions are  
often very short and sporadic. Also, most two-way  
communication uses relatively low power, 50 to  
1000 watts. The amateur radio operators are  
easiest to find; the others can be very difficult.  
Signals are also affected by the eleven year  
sunspot cycle. Signals will be poor through 1996  
then the signals will get continually better until  
peaking in 2002 when reception will be excellent.  
Overall, very good reception can be expected from  
about 1998-2005.  
3. Put the FINE TUNING control knob (right side  
of the radio) in its center position.

Finding SSB signals can be like seeking a “needle in  
a haystack”, so be patient! The easiest place to find  
SSB communication is at night in the amateur band  
shown below at 3700-4000 KHz.
