this is the installation guide for SIM  program : 


System Requirements
	If you are already using another sound-card based digital mode, you are all set.  
	SIM  can use either the built-in sound card or an external sound card based 
	interface such as: SignaLink, RigBlaster, Navigator or a home-brewed interface
•	SSB transceiver and antenna.
•	Computer running Windows XP or later, but it should also run under Linux +Wine,
	 OS X, and probably FreeBSD and other Unix-like operating systems.
•	1.0 GHz or faster CPU and 100 MB of available memory 
•	Monitor with at least 1024 x 780 resolution (more is better)
•	Sound  devices supported by your operating system.
•	Audio cable or equivalent USB connection between transceiver and computer.
•	Computer-to-radio interface  is using a serial port, to switch on/off your PTT line,
	and/or communicate with the "CAT" control, Or VOX for T/R switching.
•	No need to synchronise your computer clock to UTC.



Installation and Setup: 

1.	SIM_PSK can be downloaded from the SIM31Home page:

        http://www.on4nb.be/sim31.php 

	or direct download :

	http://www.on4nb.be/last_release/sim_psk.rar  

        NB: To have the best decoding performance and the lastest enhanced options, please 
	make sure to get the newest daily version (V68XX) available from the SIM31 Home page.
	Check for new releases at least once a week. Sometimes changes are made that break 
	compatibility between versions.

2.	For your first installation, download the .rar file, it contains all the supporting files.
	 
 
3.	Manually, create a new installation directory, 
	example  C:\SIM31\  
	(to avoid permission problems, DO NOT place this directory inside Windows directories.)

4.	Unzip the .rar file into the new directory. 8 files will be installed.
	-   sim_psk.exe                  (excutable file )
        -   SIM_Log_Viewer.exe           (external Log viwer program file)
        -   ASCII_Converter.exe          (external Ascii conversion tools)
	-   pskreporter.dll              (library needed for PSK-Reporter option)
	-   HRD5_InterfaceSIM.dll        (library needed for Ham Radio deluxe interface)
	-   sim_users_guide_en.pdf       (English user’s guide)
	-   sim_users_guide_fr.pdf       (French user’s guide)
	-   SIMCQ.wav                    (sound alert when a SIM31 frame was received)
	-   Install_SIM_V6XXX.txt        (this file.)

5.	Manually create a shortcut on your desktop or your taskbar pointing to sim_psk.exe 

6.	Run the shortcut to start SIM .

7.	When SIM starts, a pop up window appears allowing you to configure your sound 
	card plus  other setting parameters.  



the most easy way for installing new updates :
 1) Juste unzip newest uploaded sim_psk.rar file into the old folder.
 2) unziped files should overdrive old ones.
 3) Run the same old shortcut to start SIM . 

Good Luck With SIM31 mode.
