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. 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. You will have some success, but not nearly as good as during the late afternoon and evenings. Similar to 25m. 15 EVENING/NIGHT LISTENING This is the best time to listen, because the broadcasters are deliberately transmitting to North America. 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 radio's 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. [. . . ] inding SSB signals can be like seeking a "needle in a haystack", o be patient!The easiest place to find SSB communication is at ight in the amateur band shown below at 3700-4000 KHz. Put the FINE TUNING control knob (right side of the radio) in its center position. Use the FIND TUNING control knob to fine tune signals. 23 Below are some selected frequency ranges on which SSB communication can be found. [. . . ]
