 I INTRODUCTION

RadioRaft version 2.0 is a DOS program capable of decoding many of the 
radio data transmission modes found in the HF or shortwave radio bands. To 
aid in identification of unknown signals, RadioRaft version 2.0 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 2.0 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 (IRQ 4, address 3F8) or COM 2 (IRQ 3, 
address 2F8).
RadioRaft version 2.0 will only work on machines running MSDOS version 3.3 
and above.

 II LICENSE

RadioRaft 2.0 is not public domain software.

RadioRaft 2.0 is a shareware. The master installation files may be freely 
copied, used 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 make a registration payment of US$28 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\

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 2.0 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 12 master installation files:

 FILE_ID.DIZ Text file of a RadioRaft introduction, for the BBS (english)
 README.TXT How to install (english)
 LISEZMOI.TXT How to install (french)
 ORDER.TXT Order form for the registration (english)
 COMMANDE.TXT Order form for the registration (french)
 RAFTFREQ.TXT Some short wave frequencies to help the beginner (english)
 INSTALL.EXE Installation program (english)
 INSTALF.EXE Installation program (french)
 RADIORAF.HLP Help text file - Reference manual (english)
 RADIORFT.HLP Help text file - Reference manual (french)
 RAFTC200.OVL RadioRaft 2.0, 1st program file
 RAFTL200.OVL RadioRaft 2.0, 2nd program file

These files should all be in placed in a temporary directory and 
INSTALL.EXE must be run from there.

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. Choose a directory different from that which 
contains 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 $28 registration fee. 

During installation, a subdirectory named \MASTER will be created under the 
destination directory and the 12 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 UP TO DATE

Ver. 2.00 first version
Ver. 2.01 - the english documentation has been corrected
          - no modification of the executable program
__________________________________________________
 V BUGS

(UPDATED 3/20/97) 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 Setting/AF interface). This problem can 
occur with Packet 1200 bps.

__________________________________________________
 VI 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.
