23 DAY BANDS / NIGHT BANDS
DAY BANDS / NIGHT BANDS – THE
DIFFERENCE IS VERY IMPORTANT
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.
Shortwave listening is generally at its poorest during the daylight hours of about two hours after
sunrise until about two hours before sunset. The major reason for this is that the broadcasters are not
transmitting to North America at this time, assuming 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. Typi-
cally, daytime shortwave tends to be better in Eastern North America than in Western North America.
