BEGINNER'S GUIDE TO THE SHORTWAVE BANDS

Listed below are the characteristics of the major shortwave bands. Follow these guidelines for best listening results. Bucause shortwave signals depend on such factors as the sun, the ionosphere and earth itself, signals canot be heard on all bands throughout the day. Some bands are best during the daylight hours, and some are best at night. If the term "band" is new to you, please read the section titled WHAT ARE BANDS?

DAYTIME LISTENING

Shortwave listening is generally at its poorest during the daylight hours of about 10 a.m. to 3 p.m. The major reason for this is that the broadcasters are not transmitting to North America at this time. They assume 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. You will have some success, but not nearly as good as during the evening hours. The best bands are BOLD.

DAY BANDS	CHARACTERISTICS
13m	Results vary. Worth trying.
16m	Similar to 19m.
19m	The best daytime band.
22m	Similar to 19m with fewer stations.
25m	Best around sunrise and sunset. Results vary during mid-day.
31m	Similar to 25m.

EVENING/NIGHT LISTENING

This is the best time to listen, because the broadcasters are deliberately transmitting to North America. These bands may be extremly good around sunset and sunrise too. Best bands are BOLD.

NIGHT BANDS	CHARACTERISTICS
19m	Summer months.
22m	Summer months.
25m	Best two hours before/after sunset/sunrise.
31m	Good all night everywhere.
41m	Good all night in Eastern North America; varies in Western North America.
49m	The best night band everywhere.

NOTE: Getting close to a window may substantially improve your reception. The construsion materials of some buildings simply do not let signals in very well. Signals penetrate wood frame buildings easiest, while concrete and brick buildings usually block signals. If you are in a building with one or more stories above you, signals can also be impaired in strength. In such a situation, position yourself and especially the radio's antenna, as close to a window as possible while listening.

If you have ever listened to AM or FM radio, then you already know what a band is. The AM band is 530-1600
