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.
|
|
|
|
I recommend that you follow the installation instructions especially if you
|
|
are moving from v2.2 to v2.3 or later, of WSJT-X or you have upgraded macOS.
|
|
|
|
Double-click on the wsjtx-...-Darwin.dmg file you have downloaded from K1JT's web-site.
|
|
|
|
Now open a Terminal window by going to Applications->Utilities and clicking on Terminal.
|
|
|
|
Along with this ReadMe file there is a file: com.wsjtx.sysctl.plist which must be copied to a
|
|
system area by typing this line in the Terminal window and then pressing the Return key.
|
|
|
|
sudo cp /Volumes/WSJT-X/com.wsjtx.sysctl.plist /Library/LaunchDaemons
|
|
|
|
you will be asked for your normal password because authorisation is needed to copy this file.
|
|
(Your password will not be echoed but press the Return key when completed.)
|
|
Now re-boot 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
|
|
|
|
If shmmax is not shown as 52428800 then contact me since WSJT-X will fail to load with
|
|
an error message: "Unable to create shared memory segment".
|
|
|
|
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. It might be necessary if you
|
|
upgrade macOS.
|
|
|
|
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.
|
|
|
|
Depending on your macOS you might see a pop-up window suggesting that wsjtx wants to use the
|
|
microphone. What this means is that audio input must be allowed. Agree.
|
|
|
|
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. Visit Section 11 of the User Guide for information about log files
|
|
and how to access them.
|
|
|
|
Finally, visit the Radio panel. WSJT-X is most effective when operated with CAT
|
|
control. You will need to install the relevant Mac device driver for your rig,
|
|
and then re-launch WSJT-X. Return to the Radio panel in Preferences and in
|
|
the "Serial port" panel select your driver from the list that is presented. If you
|
|
do not know where to get an appropriate driver, contact me.
|
|
|
|
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 and possible solutions to any problem you might have.
|
|
|
|
Please email me if you have problems.

Addendum: Information about com.wsjtx.sysctl.plist and multiple instances of WSJT-X.
|
|
|
|
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. The com.wsjtx.sysctl.plist file is used for this purpose. You can
|
|
use a Mac editor to examine the file. (Do not use another editor - the file
|
|
would probably be corrupted.)
|
|
|
|
It is possible to run two instances of WSJT-X simultaneously. See "Section 16.2
|
|
Frequently asked Questions" in the User Guide. If you wish to run more than two instances
|
|
simultaneously, the shmall parameter in the com.wsjtx.sysctl.plist file needs to be modified as follows.
|
|
|
|
The shmall parameter determines the amount of shared memory which is allocated in 4096 byte pages
|
|
with 50MB (52428800) required for each instance. The shmall parameter is calculated as:
|
|
(n * 52428800)/4096 where 'n' is the number of instances required to run simultaneously.
|
|
Remember to reboot your Mac afterwards.
|
|
|
|
Note that the shmmax parameter remains unchanged. This is the maximum amount of shared memory that
|
|
any one instance is allowed to request from the total shared memory allocation and should not
|
|
be changed.
|
|
|
|
If two instances of WSJT-X are running, it is likely that you might need additional
|
|
audio devices, from two rigs for example. Visit Audio MIDI Setup and create an Aggregate Device
|
|
which will allow you to specify more than one interface. I recommend you consult Apple's guide
|
|
on combining multiple audio interfaces which is at https://support.apple.com/en-us/HT202000.
