Because shortwave signals depend on such fac-
tors as the sun, the ionosphere and interaction
with 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. Here are some good ‘rules of thumb’.
• In general, the bands with frequencies
below 13000 KHz are better at night and the
bands with frequencies above 13000 KHz are
best during the day. This guideline is not ‘cast
in concrete’ but is a useful general rule of
thumb.
• Around sunrise and sunset, both the day
and night bands might be good, sometimes
exceptionally good.
• In the summer time, the day bands often are
good into the early night.
• While most shortwave stations are found
within the frequency limits of these defined
bands, some are found outside of them. It
pays to take the time to tune in-between
bands too.
• These guidelines can be used worldwide and
are not dependent on location.
Listed on the next page are the characteristics of
the major shortwave bands. Follow these guide-
lines for best listening results.
