SHORT-WAVE (SW)
Your world receiver can receive an number of wavebands.
Most of these are known and tuning to 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 wavelength fairly often. In the short-wave
range between 10 and 100 meter wavelength (frequencies of
30-3 MHz resp.) nine bands between 10 and 50 meters are
allocated to short-wave broadcasting, with another four bands
between 60 and 120 meters for broadcasting in the Earth's
tropical areas. The latter are roughly located between the
latitudes of 30° north and 30° south, ie, around the equator.
Most short-wave broadcasting bands, indicated in the short-
wave table, are allocated for the whole world and can be used
for international broadcasting. They are so far the only wave-
lengths which allow direct 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.
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 the Earth. Due to the direction
of the 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.
USE OF THE STAND
Fold out the stand on the rear of the set. You may now use the
set in an inclined position.
