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.

GENERAL

Short Wave (SW)
Your world receiver can receive a 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 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 short-
wave 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.
SW Tuning mode (meterband/continuous)
Your Yachtboy P-2000 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 meterbands.
