Here the general things are explained of
how to obtain weather data with a short-wave radio. This info is actually 20
years old this information that has been adapted slightly because the
conditions are still the same. This is a description off a program in the
sixth generation. The known options have been adapted to use the newest
possibilities of the computers and software generation of today.
Newcomer Info
SeitFor a long time weather information and
nautical warnings have been sent by shortwave radio, so that ships can
receive them. This information can be displayed on a computer using a
decoder-software. Secoder-Software can be got here and there and also can be
obtained in the internet as stolen copies. But there is a good reason why
such software is not accepted, try them out and you will soon be our
customer because once you have bought all the hardware you will not give up
that easily and will then get hold of our software. The best quote we found
in the internet says:
Other programs at best only emulate part of what this program is capable of.
Only with the BONITO-Software is it
possible for an amateur to understand the complex weather data you do not
have to study meteorology to understand the weather.
For this you need::
-
A computer with a Pentium-Processor
-
A sound card with a LINE-IN
or Microphone input
-
a free comport or USB-port
with an adapter
that fulfils a serial port
-
and a Microsoft Windows
newer older than Windows 95
-
An SSB-receiver, if possible remote
controlled. All World receivers can be used such as: Sony, Panasonic,
Grundig, Siemens or others with SSB-reception. These receivers can not use
time control per TimeManager we recommend controlled receivers such as:
YAESU, ICOM, KENWOOD, NRD, AOR, Skanti and so on.
-
A antenna. We recommend a 6m long wire
antenna and with sail boots the backstay only if this is not possible as
with motor boats we recommend an active rod antenna.
-
A MeteoCom-Version with the program
expansion for the radio reception these are the software packs that you
can only purchase. The free MeteoCom-web-version has no radio control.

The RadioControl of MeteoCom
In the MeteoCom 6.0 a RadioControl is
intergrated. This is a program expansion for the radio reception. The free
MeteoCom-Web-Version does not have a RadioControl. This RadioControl is used
for the reception of types of weather data.
You can connect two shortwave radios at the same time and a Navtex receiver.
Normally a skipper will only use one channel the reception with two
receivers and a Navtex receiver is normally used by professional seafaring
people so as to be able to have reception without any problems and safety
comes first.
The Digital Sound-Processor (DSP) from the sound card is used von and
replaces the usual Filter-Modem. That is why the quality of the evaluation
is a lot higher than with anything else. The program works in the
background, while you for example look at the already received data with the
MeteoViewer or use a sea card program, it is also possible to work with a
different program this is called multi tasking and you will then be using
the nature of Windows to the full.
The FrequencyTimeManagement
The Radio is controlled fully automatically by timer over an integrated
frequency list. All spoken messages (Audio), weather fax, Morse, RTTY and
Navtex are decoded and recorded and the new messages are sorted and old ones
erased. Because nobody knows what is being transmitted and for which region
the weather data is meant a ScheduleManager is integrated, this
ScheduleManager gives information on who/ when/ what is sent for which
region. The data can be updated from the internet.
Weather card-reception FAX
The problematic with the reception of weather cards by shortwave radio are well known. That is why in the program there are a few accessories that are helpful every shift is possible, bandwidth and every offset. The usual modules for the cards are 267, 288, 357, 576 by 48, 60, 90, 120, 180, 240 rotations per minute. The filters are used to eliminate disturbance.
Telex-Reception RTTY, SYNOP, NAVTEX
Modes:
-
Synchronic und asynchrony modes
-
BAUD = 45-300 Baud
-
BAUDOT = Standard
RTTY
-
SITOR / FEC =
NAVTEX
-
SHIFT =
85,170,425, 825 and Variable
-
Filter = Every bandwidth and Offset
Clear text, forecasts and warnings are automatically saved and can be displayed by the
MeteoViever.
Synop-Message Reception
The RadioControl uses encrypted data, that are received in RTTY and
prepared metrologically and mathematically. This synoptical data is
decoded into clear text and placed in to the weather card so that they may
be used by the MeteoViewer. The data is displayed as Isobars, Isotherms or
as small symbols for Wind, temperature, rain, pressure and so on.
Morse-Text Reception
The mode Morse code is decoded by a special part of the program otherwise
the function is the same as RTTY. |
