LISTENING HINTS

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

The information in this section can help you make the most of your DX-398.

REFERENCE SOURCES

Many books and magazines about shortwave listening are available through your local library or news- stand. Consult sources such as the World Radio Handbook, Radio Ama- teur’s Handbook, Passport to World Band Radio, Monitoring Times, and Popular Communications. These pub- lications can help you learn about the conditions that make long-distance re- ception possible and provide up-to- date listings for shortwave broadcasts in English and in other languages.

using the frequency’s wavelength. For example, the 19-meter band refers to the range of frequencies with waves about 19 meters long.

Use the following equations to convert kHz, MHz, and meters.

To convert MHz to kHz, multiply by

1,000. For example:

9.62 MHz 1000 = 9,620 kHz

To convert kHz to MHz, divide by

1,000. For example:

2780 kHz 1000 = 2.780 MHz

To convert MHz to meters, divide 300 by the number of MHz. For example:

300 7.1 MHz = 42.25 meters

To convert meters to MHz, divide 300 by the number of meters. For exam- ple:

300 42.25 meters = 7.1 MHz

FREQUENCY

CONVERSION

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

Amateur radio operators generally re- fer to the frequencies they operate on

BAND ALLOCATION

Certain bands are set aside for specific purposes.

Amateur Radio Frequencies

Tuning to the amateur radio frequen- cies can be interesting and helpful, be- cause amateur radio operators often broadcast emergency information when other means of communication break down.
