folder named 5.21

will need help/guidance to update it please.


Also, after rebuilding hamlib3 then I did the regular build-wsjtx rinstall.

failed with a minor problem re "DOC .. early on I knew how to set
WSJT_GENERATE_DOCS:BOOL to OFf  i found CMakeCache.txt but dunno if
there is a current one outside the latest build from which the build
version is made.


So I ignored error and ran 7178-Dirty .. same 49% problem.

I'd made no updates. No changes. Just ran it late in the evening and
then early morning then ran it again an never did anything but HOG

Re: [wsjt-devel] r7178 was working and now uses 49% CPU

[Chuck Yahrling]

That icon is for jtsdk-py which is used to build wsjt. I build wsjtx using
jtsdk-qt. Sanity check: you are building WSJTX, right? I mean, AFAIK WSJT
is fixed at release 10 but things often change without notice.

your complete JTSDK should have a kit of 4 "batch" files:

JTSDK-MSYS
JTSDK-QT
JTSDK-PY
JTSDK-DOC

see attached.

I run JTSDK-MYSYS, then enter build-hamlib3 to make sure I have latest
hamlib3 in my build. This must be done 1st. Bill has not done anything
lately with hamlib3 but no telling when he'll change something so it's good
insurance IMHO.

Then I run JTSDK-QT and type build-wsjtx rinstall. This puts the build in a
new directory alongside previous builds.
BTW, you have to set at least 3 options for both MSYS and QT to run
correctly for our purposes. I also set autorun in JTSDK-QT which starts the
new build as soon as it's done in a terminal << which is good for seeing
any error messages you would not see just launching the executable.  There
are help menus that explain the options inside MSYS and QT. If this is all
foreign I will forward Greg Beam's email introducing the options that need
to be set.

HMMM, maybe you are on the old QT 5.? instead of new QT 5.5. That's worth
verifying as recently the dev team moved the build to qt5.5 in the rc1.7.0
code train. You may remember some posts about XP not running wsjtx when
that happened. So you should check the options. If you've never done this
before I can walk you through it. Let me know if this is your build setup
and we'll go from there.

Re: [wsjt-devel] r7178 was working and now uses 49% CPU

[Black Michael]

It's an option in jtsdk to keep unique versions that is not turned on by 
default.
You can always go backward with "svn revert -r 7177" for example in 
JTSDK\src\wsjtx
Then you just build without updating svn.

So you're not using Greg's JTSDK for windows?  Good idea to get it
installed if not.

Also, did you rebuild hamblib3 before doing the wsjtx build?

I'm building 7178 now and will report back later.

Re: [wsjt-devel] r7178 was working and now uses 49% CPU

[Steven Franke]

Hi Chuck, Bill, and all, 

To add to Bill’s comments - the setting that is selected in the Decode menu 
will also affect CPU usage. The Deep setting is much more cpu-intensive than 
the Fast setting. The Normal setting will be somewhere in between.

Hi Chuck & all,

setting a narrower frequency tolerance will cause the decoder to do less 
work as it has less bandwidth to scan for potential signals. Obviously 
the frequency accuracy of your and your QSO partner's rigs becomes more 
critical if working with narrower frequency tolerances.

Hi Bob,

MSK144 mode now uses a continuous decoding algorithm while receiving. 
This will use a lot of CPU power but that is not necessarily an issue. 
You have not said what is not working. Assuming you have a dual core CPU 
or a single core with hyper-threading then it would seem that the MSK144 
decoder is fully utilizing one CPU thread and the other is available for 
everything else like the user interface, rig control, audio streaming etc..

Do not expect to be able to run other CPU intensive applications on a 
slow single or dual core processor while decoding on MSK144 mode, the 
decoder has to do a lot of work to continuously scan the incoming audio 
for potential decodes.

hmm, if you do build-wsjtx rinstall it puts each build in a new directory

have anything in the email client which deletes after a day on the computer.

which it did over-ride ... my bad i guess.  That build-process, which

ok. I did a post to wsjt group called win7 and vista performance hack which
has details FYI.

reverting is as easy as quitting the new version and launching the old one,
if it's there.

that is, if you did not erase it yet.

check your processor utilization with task manager.

see if there is a svchost hogging the cpu.

if there is, rick click and end process tree to see if that helps.
