Multimode Radio Data Decoder Software for
12 ARQ modes, 10 FEC modes,
3 packet modes and many others ...
RadioRaft is a multimode radio data decoder software, created
by François Guillet, F6FLT. It allows decoding the most of data transmission
modes used by many services: maritime, aeronautical, emergency, radioamateurs,
press agencies, embassies, armed forces, police, humanitarian expeditions...
For more details on the features, see below the "Modes and features" section.
RadioRaft was primarily intended to enthusiastic in radio
technology but several organizations use it now for professional monitoring
as well as novices and beginners because it's so easy to use.
What you need for RadioRaft:
order to run RadioRaft you need at least a PC 486 or Pentium with a 3"5 floppy disk
driver, MsDOS 6.2 or above, VGA screen, a COM port, a radio receiver and a
simple interface connecting the speaker or audio output to the
COM port. You don't need Windows (see the FAQ).
installing RadioRaft on your PC, just connect your PC to the receiver through
the interface (HamComm/JVFAX compatible), or through a demodulator,
and RadioRaft works.
RadioRaft software package includes the complete documentation in 2 files:
the RadioRaft user's main
guide and the RadioRaft modes user's
guide. They are provided both in HTML and TEXT format.
You may read them right now from your browser. They are also available from
the "Help" menu when RadioRaft is running.
RadioRaft functioning is full automatic. You just need to tune your receiver
on a station using a compatible mode (see the list below). RadioRaft
tracks the signal, search for the right mode, the right speed, the right shift
and displays any possible text in just a few seconds.

Asked Questions (FAQ) on RadioRaft
- Does RadioRaft decode FAX, G-TOR, CLOVER,
currently does not decode any other modes than those listed in the Features
- When could I use a sound card instead
of the interface?
sound card is the best way for entering the signal from the receiver. But
the use of a sound card is not yet planned, question of time (nevertheless
see the following question).
- How can I improve the decoding?
- Filter the
audio signal. You may use the PBT (pass band tuning)
of your receiver, or an external filter as a DSP filter. You will have to
adjust manually the filter's characteristics to each audio signal you are
receiving. If you run RadioRaft from Windows (see below the section "RadioRaft under Windows"), you can run a DSP software in the same
time: pass the signal to the line input of the sound card and connect its
output to the "Hamcomm" interface.
SR5 from John Reeve G8ROD is such
a software with many efficient features. Download it from his site: www.ar5.com, at the section "SR5". It's a shareware with a
time limited trial version.
- Use a demodulator
instead of the simple "Hamcomm" interface.
A "Hamcomm" interface converts the analogue FSK signal from the
receiver audio output into the same but square signal, compatible with the
PC COM port.
A demodulator converts the analogue signal into the data signal which is the
stream of information bits.
With the "Hamcomm" interface, RadioRaft has to make itself the demodulation.
But the demodulation of the square signal cannot be as good as this of the
same analogue signal that could process an external demodulator. Be careful:
"Hamcomm" interfaces are sometimes named "demodulators"
by their distributors, when they have no function of demodulation.
- Does RadioRaft decode NAVTEX?
is not a transmission mode. NAVTEX is a system of messages sent to navigators,
using the SITOR-B transmission mode on the frequencies of 490 and 518 kHz.
When you select SITOR-B, RadioRaft displays NAVTEX messages as they are. The
heading of a NAVTEX message is formatted, and the rest is as plain text.
Note that in Europe, unidentified stations transmit at 100 bauds on 510.5
and 521.5 KHz 24 hours a day. Don't confuse these with NAVTEX transmissions.
NAVTEX occurs at a particular time (about every 4 hours) depending on
the station and continues around 10 mn.
- How does RadioRaft decode aeronautical
bulletins or ACARS?
letters groups or Acars codes are displayed as they are. There is no 2nd level
You need the specifications of the Acars mode to interpret all the fields.
But air plane identifier and texts in the Acars frame are in ASCII plain text.
- Can I use a modem for a telephone line?
is possible, but not simple. For FSK modes with speeds up to 300 baud, you
need a modem with V.21 mode, and for 1200 baud V.22. The output of the modem
must be connected to the CTS input of the serial port (not the RX input).
See the RadioRaft documentation for more details about this subject.
You can't use a phone modem for POCSAG.
It is a Microsoft
bug occuring on ACPI compatible PCs when the
COM power management is set (ACPI = Advance Configuration and Power
Interface). It is frequently encountered on notebooks under Windows 98.
When restarting in MsDOS, the power for the COM port controller is switched
off. All DOS programs are no longer able to access the serial ports.
To prevent the problem, you need to disable ACPI
for the COM port by modifying a key in the Windows registry. Be carefull when
modifying the registry. Save it before modifying.
To modify the key, click the button "Start" then "Execute".
Write "regedit" in the field then click OK.
Here is the registry key you have to modify:
Set the value from "01 00 00 00" to "00
00 00 00" and restart Windows.
Then RR works each time when restarting from Windows
into MsDOS mode.
- I get a memory error when installing or running RadioRaft.
What can I do?
needs 550 Kb to run. RadioRaft is a real mode DOS program, so it has access
only to the conventional memory, i.e. 640 Kb maximum even tought you have
128 Mb installed on your PC!
Unfortunatly when DOS starts, it uses a part of the conventional memory to
place drivers for the screen, the keyboard, the mouse, the sound card...
It is made by the files "CONFIG.SYS" and "AUTOEXEC.BAT"
which are located on the root of your hard disk. You can edit these files
and remove the lines installing drivers possibly not needed.
you run RadioRaft from the .pif files (see below the section "RadioRaft under Windows"), you can set these parameters without having
to modify the AUTOEXEC ET CONFIG files.
Click right the icon "RadioRaft real mode". Select "Properties"
then the "Program" tab.
Go to the "advanced setup". "MS-DOS mode" must be checked
so this method can't be used for running RadioRaft in a Windows box.
Specify our own configuration in the fields "autoexec.bat" and "config.sys".
improve the DOS memory allocation for RadioRaft in a Windows environment,
CONFIG.SYS and AUTOEXEC.BAT may look like:
REM Set the path for the mouse in the following line
REM Select your code page (850 is an example for French)
REM The 2 following lines are not required with English standard.
LH MODE CON CP PREPARE=((850) C:\WINDOWS\COMMAND\EGA.CPI)
LH MODE CON CP SELECT=850
REM Select your keyboard (fr is an example for French)
REM The following line may be removed when standard English keyboard is used.
LH KEYB FR,,C:\WINDOWS\COMMAND\keyboard.sys
is a pure DOS program working in "real mode" (see above the FAQ
for more information, or if you get a memory error when RadioRaft starts).
Theoretically you have to boot your PC in DOS mode before launching RadioRaft.
RadioRaft is only compatible with Windows 98 and previous
RadioRaft is not compatible with Windows 2000 or XP. If you have Windows
2000 or XP, you will have to boot your PC from a MS-Dos startup floppy
Windows XP, you can go to "My computer". Click on the A drive
and the choose Format
disk you are given the option to make a MS-Dos startup disk. Do this
and then boot from that disk.
can also put in the autoexec.bat:
so it boots straight into RadioRaft.
to Barry Stone G6SRE for this interesting information.
you may run RadioRaft without quitting Windows: with a Pentium II or more,
the decoding is a bit disturbed but all's well up to 200 bauds. Faster the
baud rate, worse the error rate: Windows slows the real time decoding process
even if there is no other applications working in the same time. At 1200 bauds
or more it's not possible to get a correct decoding under Windows.
order to launch easily RadioRaft from Windows, two "PIF" files are
provided, outside of the RadioRaft package. See the section Download RadioRaft to get them. One permits to launch RadioRaft in
real mode DOS as you would reboot your PC, the other one to run RadioRaft
in the multi-task Windows environment with the inconvenient mentioned above.
Put these files onto your desktop or in the RadioRaft folder with shortcuts
onto your desktop. You will get the 2 icons ("RR real mode" and
"RR under Windows").
If you have
not installed RadioRaft in the default folder (C:\RADIORAF), click right on
the icons, select "Properties" then the "Program" tab
and correct the path to access the RadioRaft directory.
under Windows" runs RadioRaft in full screen mode. You can move to other
Windows applications using the key Alt+Tab or coming back to a window using
"Alt+enter". You may also modify the icon properties and choose
the Window size in the "program" tab.
the best decoding, RUN RadioRaft from the "RR real mode" icon.
