LISTENING HINTS

Shortwave listening is a hobby with thousands of participants worldwide. It requires no special knowledge or skills, but your en- joyment increases as you gain experience and develop special lis- tening techniques.

The information in this section can help you make the most of your DX-397.

REFERENCE SOURCES

Publications about shortwave listening such as Listening to Short- wave Radio (available at your local RadioShack store), the World Radio Handbook, Radio Amateur’s Handbook, Passport to World Band Radio, Monitoring Times, and Popular Communications are available through your local library or newsstand. These publica- tions can help you learn about the conditions that make long-dis- tance reception possible and provide up-to-date listings for shortwave broadcasts in English and in other languages.

FREQUENCY CONVERSION

A band is a group of frequencies. Sometimes, bands are grouped according to their wavelengths, in meters. The tuning location of a station can be expressed as a frequency (kHz or MHz) or a wave- length (meters).

Amateur radio operators generally refer to the frequencies they op- erate on using the frequency’s wavelength. For example, the 19- meter band refers to the range of frequencies with waves about 19 meters long.
