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.
