Notes on WSJT-X Installation for Mac OS X
|
|
-----------------------------------------
|
|
|
|
If you have already downloaded a previous version of WSJT-X then I suggest
|
|
you change the name in the Applications folder from WSJT-X to WSJT-X_previous
|
|
before proceeding.
|
|
|
|
If you have installed a previous version of WSJT-X before then there is no
|
|
need to change anything on your system so proceed to NEXT.
|
|
|
|
BEGIN:
|
|
|
|
There are some system matters you must deal with first. Open a Terminal window
|
|
by going to Applications->Utilities and clicking on Terminal.
|
|
|
|
Along with this ReadMe file there is a file: sysctl.conf. Drag this file to your Desktop.
|
|
Then type in the Terminal window:
|
|
|
|
cd $HOME/Desktop
|
|
|
|
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 at least 33554432 (32 MB) then you can close the Terminal window
|
|
and skip the next steps and go to (NEXT).
|
|
|
|
Now move this file 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 should make certain that NO error messages
|
|
have been produced during these steps. You can now close the Terminal window. It will
|
|
not be necessary to repeat this procedure again, even when you download an updated
|
|
version of WSJT-X.
|
|
|
|
NEXT:
|
|
|
|
Drag the WSJT-X app to your preferred location, such as Applications.
|
|
|
|
You need to configure your sound card. Visit Applications > Utilities > Audio MIDI Setup and
|
|
select your sound card and then set Format to be "48000Hz 2ch-16bit" for input and output.
|
|
|
|
Now double-click on the WSJT-X app and two windows will appear. Select Preferences under the
|
|
WSJT-X Menu and fill in various station details on the General panel. I recommend checking the
|
|
4 boxes under the Display heading and the first 4 boxes under the Behaviour heading.
|
|
|
|
Next visit the Audio panel and select the Audio Codec you use to communicate between WSJT-X
|
|
and your rig. There are so many audio interfaces available that it is not possible to give
|
|
detailed advice on selection. If you have difficulties contact me. Note the location of the
|
|
Save Directory. Decoded wave forms are located here.
|
|
|
|
Look at the Reporting panel. If you check the "Prompt me" box, a logging panel will appear
|
|
at the end of the QSO. Two log files are provided in Library/Application Support/WSJT-X.
|
|
These are a simple wsjtx.log file and wsjtx_log.adi which is formatted for use with logging
|
|
databases.
|
|
|
|
Finally, visit the Radio panel. WSJT-X is most effective when operated with CAT control. You
|
|
will need to install the relevant Mac driver for your rig. This must be located in the system
|
|
driver directory /dev. I use a Prolific USB-Serial Adapter to a Kenwood TS870s and the relevant
|
|
driver is /dev/tty.PL2303-00002226. You should install your driver and then re-launch WSJT-X.
|
|
Return to the the Radio panel in Preferences and insert the full name of your driver in the
|
|
Serial Port panel. Such as: /dev/tty.PL2303-00002226 or what ever driver you have. The /dev/
|
|
prefix is mandatory. Set the relevant communication parameters as required by your transceiver.
|
|
|
|
WSJT-X needs the Mac clock to be accurate. Visit System Preferences > Date & Time and make sure that
|
|
date and time are set automatically. The drop-down menu will normally offer you several time
|
|
servers to choose from.
|
|
|
|
On the Help menu, have a look at the new Online User's Guide for operational hints and tips.
|
|
|
|
Please email me if you have problems.
