DAY BANDS / NIGHT BANDS – THE DIFFERENCE IS
VERY IMPORTANT
Because shortwave signals depend on such factors 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.
