DAY BANDS / NIGHT BANDS

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.
