LOCKING THE

CONTROLS

The lock feature prevents you from ac- cidentally turning the receiver on or off, changing the band or frequency, or se- lecting front-panel buttons.

Set the lock switch to to lock all the front-panel buttons and the ROTA- RY TUNING dial. You can still adjust VOLUME, TONE, and other controls. Set the switch to the other position to unlock the buttons.

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.

Note: To lock only the ROTARY TUN- ING dial, see “Using the Rotary Dial” on Page 10.

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-392.

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 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
