GENERAL RADIO OPERATION HOW TO TURN THE RADIO ON AND OFF Press the ON/OFF button. HOW TO LISTEN TO YOUR LOCAL AM STATIONS 1. On the YB 400PE, the AM broadcast band is called medium wave. When you are listening to AM, the letters MW appear in the display. 2. Press the ON/OFF button to turn the radio on. 3. Press the AM button several times, until MW appears near the center of the display. 4. If STEP appears in the display, press the STEP button to choose 10 KHz tuning rate. 5. Automatically tune using the AUTO TUNING button. The radio will automatically stop on stations. A quick press-and-release tunes up-frequency; a long press-andrelease tunes down-frequency. 6. Manually tune using the tuning button. 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. HOW TO LISTEN TO YOUR LOCAL FM STATIONS 1. Press the FM Button. 2. Automatically tune using the AUTO TUNING button. The radio will automatically stop on stations. A quick press-and-release tunes up-frequency; a long pressand-release tunes down-frequency. 3. Manually tune using the TUNING BUTTONS. HOW TO USE THYE WIDE/NARROW SWITCH (left side of radio)
HOW TO USE THE STEREO/MONO SWITCH (left side of radio). 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. HOW TO USE THE TONE SWITCH Experiment and let your ears judge which position, HIGH or LOW, you like best. 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 frequyency you are presently tuned to, e.g. you can enter an FM frequency even if you are presently in shortwave. AM STATION EXAMPLE: to tune the frequency 810 kilohertz in the AM band, press 0 , then press the FREQU./METER button. FM STATION EXAMPLE: to tune the frequency 105.7 megahertz in the FM band, press 5. 7, then press the FREQU./ METER button. Be sure to include the decimal point in FM frequencies. SHORTWAVE STATION EXAMPLE: to tune the frequency 5975 kilohertz in the shortwave 49 meter band, press 5975 then the FREQU./METER button.
HOW TO USE THE STEP BUTTON 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: AM (MW): 10 KHz in the Americas; 9 KHz outside of the Americas 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. SSB: 1KHz HOW TO USE THE LOCK BUTTON 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. When the radio is on: Pressing the LOCK button locks all keys except the ON/OFF button and the SNOOZE button. 8

When the radio is off: Pressing the LOCK button locks all keys. This will keep the radio from accidentally turning on when packed in a briefcase, etc. When you want to listen to your radio, press LOCK and then the ON/OFF switch. HOW TO USE THE AM BUTTONS LAST STATION MEMORY FEATURE Pressing the AM button over and over steps through the last station tuned in MW, SW and LW. HOW TO USE THE VOLUME CONTROL KNOB Use this to control the loudness of the radio. HOW AND WHEN TO USE THE RESET FEATURE 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
HOW TO LISTEN TO SHORTWAVE STATIONS 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 22. 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. WHAT IS A SHORTWAVE BAND 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 shortwave 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.
For example, the 19 meter shortwave band encompasses the frequency range of 15100 to 15600 kilohertz. The band chart on the back of the YB400PE shows the frequency range for each band. HOW TO ENTER A SHORTWAVE BAND EXAMPLE: To enter the 25 meter band 1. Press 2. Press the FREQU./METER button. HOW TO TUNE AROUND IN A SHORTWAVE BAND AUTO TUNING: The radio will find stations for you within the shortwave band you have entered. In shortwave, this feature only works within the shortwave bands shown on the back of the radio (see the chart titled SHORTWAVE BAND AUTO TUNING RANGES).
MANUAL TUNING: Use the regular TUNING buttons to go up or down frequency. Be aware that when using manual tuning, it is possible to tune right out of the shortwave band you have entered. You are in the band as long as the bands number, e.g. 25m, is in the display. HOW TO CHOOSE THE BEST SHORTWAVE BAND TO TUNE AROUND IN This information and much more can be found in the section titled MORE INFORMATION ABOUT SHORTWAVE.
SHORTWAVE BAND AUTO TUNING RANGES:

90m: 3200-3400 KHz 80m: 3500-3800 KHz 75m: 3900-4000 KHz 60m: 4750-5060 KHz 49m: 5950-6200 KHz 41m: 7100-7300 KHz 40m: 7000-7099 KHz 31m: 9500-9900 KHz 30m: 10100-10150 KHz 25m: 11650-12050 KHz 22m: 13600-13800 KHz 20m: 14000-14350 KHz 19m: 15100-15600 KHz 17m: 18065-18170 KHz 16m: 17550-17900 KHz 15m: 21000-21449 KHz 13m: 21450-21850 KHz 12m: 24890-24990 KHz 11m: 25650-26100 KHz 10m: 28000-29700 KHz

USING THE CLOCK, ALARM AND SLEEP TIMER FEATURES HOW TO CONTROL THE ALARM CLOCK
This can be done with the radio on or off. The YB400PEs clock is a 24 hour clock only, e.g. 6oclock in the morning will read as 6:00; 6 oclock in the evening will read as 18:00. There are two clocks, TIME I and TIME II. Select one or the other by pressing the TIME 1/2 button. TIME I or TIME II shows in the display at top center. Set the time using the examples below. EXAMPLE 1: If it is 06:00 hours press 6. 0 0, then immediately press the TIME 1/2 button. EXAMPLE 2: If it is 15:32 hours press 1 5. 3 2, then immediately press the TIME 1/2 button. HOW TO SET THE ALARM CLOCK The alarm time is shown in the upper left corner of the display, under ON TIME, when the radio is off. To set the alarm to activate at 6:30: 1. Press 6. (be sure to include the decimal point) 2. Immediately press and release the ON TIME button. 3. Select the alarm mode using the AUTO button. 13

Press the AUTO button several times while looking at the upper left corner of the display. The musical note symbol wakes you to the radio playing the last station it was set to. The bell symbol wakes you to a beeper sound. When both symbols disappear and -: appears, THE ALARM IS DEACTIVATED. HOW TO USE THE ALARM CLOCKS SNOOZE FEATURE (button on top of radio) Once the alarm has activated, you can get 5 minutes more sleep by briefly pressing the SNOOZE button. You can repeat this as many times as you like. By pressing the SNOOZE button for more than 2 seconds, you can completely shut off the alarm.
HOW TO SET THE SLEEP TIMER Press the SLEEP button over and over. Each press changes the amount of time the radio will play before shutting off automatically, 60 through 0 minutes. HOW TO USE THE DIAL LIGHT (button on top of radio) The LIGHT button causes the display to be illuminated. After 10 seconds, or when the LIGHT button is pressed again, the light will go out.
MORE INFORMATION ABOUT SHORTWAVE 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. If the term band is new to you, please read the section titled, WHAT IS A SHORTAVE BAND? on page 9. DAYTIME LISTENING 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 this time. 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. DAYBANDS 13m 16m 19m 22m 25m 31m CHARACTERISTICS Results vary. Worth trying. Similar to 19m. The best daytime band. Similar to 19m (fewer stations). Best around sunrise/sunset. Similar to 25m.
EVENING/NIGHT LISTENING This is the best time to listen, because the broadcasters are deliberately transmitting to North America. These bands may be extremely good around sunset and sunrise too. Best bands are BOLD. NIGHT BANDS 19m 22m 25m sunset 31m 41m CHARACTERISTICS Summer Months Summer Months Best two hours before/after sunrise/
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 radios antenna, as close to a window as possible while listening. On the following page 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 YB400PE shows shortwave frequencies in kilohertz.

Good all night everywhere Good all night in Eastern North America; varies in Western North America The best night band everywhere
NOTE: Getting close to a window may substantially improve your reception.

WHAT IS HEARD ON SHORTWAVE RADIO? International foreign broadcasts, many targeting North America Long distance two-way amateur radio, maritime, and aeronautical communications WHAT COUNTRIES ARE HEARD ON SHORTWAVE RADIO? 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 earths ionosphere. Frequencies in BOLD are mainly used for the countrys native language broadcast.

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 22.
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 political propaganda. ARE THE SIGNALS CLEAR? Often, but not always. Todays 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. 19
IF A COUNTRY IS NOT 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. WHAT ELSE CAN AND CANNOT BE HEARD ON SHORTWAVE? You can hear long distance two-way marine, aviation, and amateur radio (ham). To receive such communications, 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 BROADCAST STATIONS BE RECEIVED? 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. HOW IS IT THAT BROADCASTS FROM AROUND THE WORLD CAN BE HEARD ON A SHORTWAVE RADIO? Shortwave radio can be heard around the world because of the earths ionosphere. Think of the ionosphere as a cloud-like layer enshrouding the earth at an altitude of 140-250 kilometers (90160) miles). It consists of electrons and ions, the density of which are governed by the sun and the earths 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.

HOW CAN I DETERMINE IF AN OUTDOOR ANTENNA WILL HELP? 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 improvement will depend on the type of antenna used. If you have questions about outdoor antennas, call Grundig technical support. WHAT TIME STANDARD IS USED IN SHORTWAVE BROADCAST SCHEDULES? Since there are many different time zones around the world, it would be impractical for shortwave broadcasters to give broadcast times for each separate time zone. To simplify matters, they list their broadcast schedules
in 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, 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.

GETTING STARTED WITH SINGLE SIDEBAND (SSB); MARITIME & AERONAUTICAL WEATHER AND COMMUNICATION FREQUENCIES; HAM RADIO COMMUNICAATION FREQUENCIES; TIME SIGNALS HOW TO TURN THE SSB FEATURE ON 1. Slide the SSB switch (right side of radio) to the ON position. 2. Use the STEP button to select 1 KHz tuning steps. STEP 1 will display in the lower right of the display. 3. Put the FINE TUNING control knob (right side of the radio) in its center position. 4. Use the FIND TUNING control knob to fine tune signals.
High end shortwave radios, such as the Grundig YB400PE, have a feature called SSB, a highly efficient way of electronically processing transmitted and received signals for two-way communication. Examples of this are amateur radio (hams), maritime, and aeronautical communication. Either upper side band (USB) or lower side band (LSB) can be used.
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.
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.
Below are some selected frequency ranges on which SSB communication can be found. All frequencies are shown in Kilohertz. AMATEUR RADIO AERONAUTICAL (usually USB) MARITIME (usually USB)
