9 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 11.
DAYT IME 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 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.
