4 GENERAL

4.1 Time zones

The earth rotates around its axis in 24 hours and around the sun In

one year.

These movements are responsible for the time differences and the

seasons on earth. Due to the direction of rotation of the earth it is

always earlier in the day to the west of where you are and later in

the day to the east of where you are.

The earth is divided into 24 time zones with a difference of one hour

between adjacent zones. The system is based on one standard time

zone, namely UTC (Coordinated Universal Time), previously GMT

(Greenwich Mean Time). Generally speaking, short-wave stations

announce their broadcasts in UTC.

To check which time zone you are now at, use the world map on the

back of the set.

4.2 Short Wave (SW)

Your world receiver can receive a number of wavebands. Most of

these are known and tuning for the required station will soon

become a matter of routine, as the stations are always to be found

at the same place on the dial and are thus tied to a fixed

wavelength and frequency. With short wave this is unfortunately

not always the case. Short wave transmitters have to change their

avelengths fairly often. In the short-wave range between 10 and 1

Oo-metre wavelength (frequencies of 30-3 MHz resp.) nine bands

between 10 and 50 metres are allocated to short-wave broadcasting,

with another four bands between 60 and 120 metres for

broadcasting in the earth's tropical areas. The

latter are roughly located between the latitudes of 30¢X north and

30¢X south, i.e. around the equator. Most short-wave broadcasting

bands, indicated in the shortwave table, are allocated for the whole

world and can be used for international broadcasting. They are so

far the only wavelengths which allow direct radio reception over

long distances. So in addition to the broadcasting services, there is

a large number of other users of short wave, for example radio

amateurs, shipping and aviation, radio navigation etc.

4.3 SW Tuning mode (meterband/continuous).

Your G-2000A has a built-in SW frequency (SW FREQ.) tuning

mode selection switch inside the battery compartment.
