[Ham-Mac] WSJT-X Decode problem after transmit

[Robert L Kalkwarf]

Ron, Did you do the following?

                          Notes on WSJT-X Installation
                          ----------------------------

There are some system matters you must deal with first.  Open a Terminal window
by going to Applications->Utilities and clicking on Terminal.

You need to visit the directory WSJT-X by typing (in the Terminal window)

   cd WSJT-X  

where cd is a Unix command to "change directory".  This assumes that the WSJT-X
folder is in your home directory.  You may have downloaded it to your Desktop in
which case you type:   (Note that Unix commands are case sensitive.)

  cd Desktop/WSJT-X

You must install the rig control program and the list of transmitters that 
the program will use.  Type:

   sudo cp hamlib.tar.gz /
   pushd /
   sudo tar -xzf hamlib.tar.gz
   sudo rm hamlib.tar.gz
   popd

Next:  WSJT-X makes use of a block of memory which is shared between different parts of
the code.  The normal allocation of shared memory on a Mac is insufficient and this 
has to be increased.   You can look at the new allocation by typing:

   cat  sysctl.conf

This shows the following:

kern.sysv.shmmax=33554432
kern.sysv.shmmin=1
kern.sysv.shmmni=128
kern.sysv.shmseg=32
kern.sysv.shmall=8192

You can check the current allocation on your Mac by typing:

  sysctl -a | grep sysv.shm

If your shmmax is already larger than 33554432 then you can close the Terminal window
and skip the next steps and go to (NEXT).

Now move this into place for the system to use by typing:

  sudo mv sysctl.conf /etc/

and then reboot your Mac.  This is necessary to install the changes.  After the
reboot you should re-open the Terminal window as before and you can check that the
change has been made by typing:

  sysctl -a | grep sysv.shm

You are finished with system changes.  You can now close the Terminal window.

NEXT:

Now use the normal Mac window and drag the WSJT-X folder and put this in the Applications folder. 
Go there (to the Applications directory) and then click on WSJT-X.

You will see the WSJT-X users guide which you should read before you start.   You will also
see the wsjtx.ini file which the application uses to store a variety of preferences.  (On a Mac
the .ini extension might be hidden.  This is a simple text file.  Do not change its name.) 
You can edit this file if needed, especially if you need to add your own driver for CAT control.  
The name of the device driver should replace User in the   CATdriver=   field.  Later you 
will see this when you open the "CAT port" menu in the Preferences menu of the WSJTX code.

Time to go.  Double-click on the application icon try it out.   Two windows should appear.  
Under the wsjtx menu you will find Preferences.  Enter your call sign and
locator and such other information as you need.   Have fun.

Please email me if you have problems.
