G4000AOPERATION MANUAL 21 HOW IS IT THAT BROADCASTS FROM AROUND THE WORLD CAN BE HEARD ON A SHORT WAVE RADIO? Shortwave radio can be heard around the world because of the earth’s ionosphere. Think of the ionosphere as a cloudlike layer enshrouding theearth at an altitude of 140250 kilometers (90160) 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 ionospheric propagation. WHAT ELSE CAN AND CANNOT BE HEARD ON SHORTWAVE? You can hear long distance twoway 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. CAN DISTANT AM/FM BROAD CAST STATIONS BE RECEIVED? FM is strictly for local stations. Daytime AM stations usually have a maximum distance of 50100 miles. At night, AM broadcast signals can sometimes be heard over much greater distances, hundreds of miles away. MORE INFORMATION ABOUT SHORTWAVE continued 20 MORE INFORMATION ABOUT SHORTWAVE continued For fully comprehensive listings of the broadcast schedules of all countries, see the broadcast guides recommended in the section titled SHORTWAVE GUIDES AND MAGAZINES on page 23. IS THERE ENGLISH LANGUAGE PROGRAMMING? Yes! Many major international broadcasters incorporate English programming. WHAT IS THE PROGRAM CONTENT LIKE? 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 programs, music oriented programs, and even politicalpropaganda. ARE THE SIGNALS CLEAR? Often, but not always. Today’s technology has greatly minimized the fading, static and interference that are natural aspects of international broadcast listening. CAN I HEAR A SPECIFIC COUNTRY? 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. IF A COUNTRY IS NOT TRANSMITTING ITS SIGNAL SPECIFICALLY FOR RECEPTION IN NORTH AMERICA, IS THEREANY 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.

MORE INFORMATION ABOUT SHORTWAVE continued 22 MORE INFORMATION ABOUT SHORTWAVE continued HOW CAN I DETERMINE IF AN OUTDOOR ANTENNA WILLHELP? 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 Grundigtechnical support. WHAT TIME STANDARD IS USED IN SHORTWAVE BROADCASTSCHEDULES? Since there are many different time zones around the world, it would be impractical for shortwave broad casters to give broadcast times for each separate time zone. To simplify matters, they list their broadcast schedules iin Coordinated Universal time (UTC), also known as Greenwich Mean Time (GMT), World Time and Zulu Time.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. To determine Coordinated Universal Time, tunein 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.

Examples of this are amateur radio (hams), maritime, and aeronautical communication. Either upper sideband (USB) or lower side band (LSB) can be used. Receiving SSB signals is not always easy. Since this is twoway communication, transmissions are often very short and sporadic. Also, most twoway 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 1996then the signals will get continually better untilpeaking in 2002 when reception will be excellent. Overall, very good reception can be expected fromabout 19982005. Finding SSB signals can be like seeking a “needle in a haystack”, so be patient! The easiest place to findSSB communication is at night in the amateur bandshown below at 37004000 KHz.HOW TO TURN THE SSB FEATURE ON 1. Slide the SSBswitch (right side of radio) to the ON position. 2. Use the STEPbutton to select 1 KHz tuning steps. “STEP 1” will display in the lower right of the display. 3. Put the FINE TUNINGcontrol knob (right side of the radio) in its center position. 4. Use the FINE TUNINGcontrol knob to fine tune signals. continued
