  I INTRODUCTION

RadioRaft version 2.1 is a DOS program capable of decoding many of the
radio data transmission modes found in the HF or shortwave radio bands. To
help in identification of unknown  signals, RadioRaft version 2.1 includes
a baud rate indicator, frequency  meter, and automatic mode detection.
Currently, RadioRaft can decode the following modes:

 - Baudot (RTTY)
 - ASCII (7 bits or IRA, 8 bits and 8 bits+parity)
 - SITOR-A (TOR/ARQ or AMTOR mode A)
 - SITOR-B (TOR/FEC or AMTOR mode B)
 - ARQ-E
 - ARQ-M (ARQ-M2, ARQ-M4, ARQ-E3, SI-FEC)
 - ARQ-N
 - SI-ARQ
 - SWED-ARQ
 - ARQ-6/90 and ARQ-6/98
 - CIS11
 - SPREAD11, SPREAD21, SPREAD51
 - AUTOSPEC
 - FEC-A
 - RUM-FEC
 - HNG-FEC
 - PACKET-RADIO (AX25)
 - MORSE (CW)
 - "DIGIT", this supplementary function allows for bit-by-bit display of
any mode.

In order to run RadioRaft version 2.1 you will need at least:
a PC AT 386 (a Pentium would be better), 650 Kb of hard disk space, 550 Kb
of free RAM, a VGA screen, a simple and inexpensive OP-AMP comparator
circuit (see circuit diagram in file RADIORFT.HLP) or more sophisticated
demodulator to pass the audio output of the radio receiver to the computer,
and access to serial port COM1 to COM 4.
RadioRaft version 2.1 will only work on machines running MSDOS version 3.3
and above.

RadioRaft 2.1 is not public domain software.

RadioRaft 2.1 is a shareware. The master installation files may be freely
copied and distributed. Unauthorized sale of RadioRaft is strictly
prohibited. The software and/or manual may not be modified in any way
without the prior written  permission by the author. The distribution
and/or copying of the executable file RADIORAF.EXE created by the
installation is also prohibited.

You are hereby granted a limited license to use this software for
evaluation purposes. If you would like to access the full range of features
that RadioRaft supports, you must contact an authorised dealer or make a
registration payment of US$30 to:

  Francois Guillet
  17 rue Michel Delalande
  F-44800 St-Herblain France

  E-mail: F6FLT@TheOffice.net
 WEB site: http:\\ourworld.compuserve.com\homepages\F6FLT\

See the file ORDER.TXT about the payment. You will then receive your
registration license and a confidential code. You must not give your
confidential code to others, as it permits the installation of the complete
version from the master files.

The RadioRaft 2.1 evaluation version is limited to the reception of the
following modes: RTTY (Baudot), Sitor-A and B (Tor/fec/arq), ARQ-E, FEC-A,
DIGIT. The other modes can be detected or selected. Text will only be
displayed in a small window of 9 characters, except in Packet mode. All
other features are the same as the fully registered version.

  III INSTALLATION

 Procedure:

 You need the 15 master installation files:

 FILE_ID.DIZ  Text file of a RadioRaft introduction (English)
 RAFTFREQ.TXT Some short wave frequencies to help the beginner (English)
 README.TXT   How to install (English)
 ORDER.TXT    Order form for the registration (English)
 RADIORAF.HLP Help text file - Reference manual (English)
 INSTALL.EXE  Installation program (English)
 RAFTC200.OVL RadioRaft 2.1, 1st program file
 RAFTL200.OVL RadioRaft 2.1, 2nd program file

 LISEZMOI.TXT How to install (French)
 COMMANDE.TXT Order form for the registration (French)
 RADIORFT.HLP Help text file - Reference manual (French)
 INSTALF.EXE  Installation program (French)

 LEESMIJ.TXT  How to install (Dutch)
 BESTEL.TXT   Order form for the registration (Dutch)
 RADIORNF.HLP Help text file - Reference manual (Dutch)

These files should all be in placed in a temporary directory (except if you
install from the RadioRaft diskette) and INSTALL.EXE must be run from
there.

Type A: <Enter> if you install from a diskette.
For installation of the English language version, enter: INSTALL <Enter>

The installation program will then prompt you to select the directory in
which to install RadioRaft. VERY IMPORTANT: CHOOSE A DIRECTORY DIFFERENT
FROM THAT CONTAINING THE MASTER INSTALLATION FILES.

If you have not registered, you can install only the evaluation version.
The confidential registration code needed to install the complete version
is provided upon payment of the US $30 registration fee.

During installation, a subdirectory named \MASTER will be created under the
destination directory and the 15 master installation files will be copied
there. After installation, you can delete the temporary installation
directory and start RADIORAFT by typing RADIORAF.EXE at the MSDOS prompt
but it is suggested that you read the helpfile called RADIORAF.HLP which is
located in the \MASTER subdirectory of your RadioRaft directory. This file
can be read and printed with any MSDOS text editor. If you use the MSDOS
EDIT command, you should set the OPTION "TABS" to 4.

The helpfile can also be read, but not printed, while RadioRaft is running.
From the main screen, select the menu Help / Main help.

  IV UPDATES and BUGS


Ver. 2.00 - first version
Ver. 2.01 - the whole english documentation is corrected
          - no modification of the executable files
Ver. 2.12 - ports 3 and 4 are supported.
          - F2 key is added for screen clear.
          - the dutch documentation is provided.


(BUGS UPDATED 6/25/97) The measurement of the mean frequency of signals
with very large shift and high baud rate is not always correct. If that
happens, inhibit the "Signal Tracking" (menu Settings/AF interface). This
problem can occur with Packet 1200 bps.


 __________________________________________________
  V REQUESTS

Any new mode using FSK modulation can be included in RadioRaft. If you have
the specifications for a mode that you think should be included in the next
version of RadioRaft, please contact me. Comments and criticisms are
welcome as well.
