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.
