Grundig World Receiver G2000A - Manual (Page 6)

GENERAL
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.
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 wavelengths fairly often.
In the short-wave range between 10 and 100-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° north
and 30° 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 are a large number of other users of short wave, for
example radio amateurs, shipping and aviation, radio
navigation etc.
SW Tuning mode (meter band/continuous).
Your G-2000A has a built-in SW frequency (SW
FREQ.) tuning mode selection switch inside the battery
compartment.
• Select A, if you only want to get reception for the
stations with the frequency within the meter-bands.
• Select B, in case you wish to obtain the frequencies
in between the gaps of the meter bands.
