Dear all,


the past days I have (hopefully) cured some soundcard treathment errors.

I hope that this fixed 2 issues:

- An error that occured when another soundcard was selected.

- An error that occured due to a buffer overload.

This last error crashed the application under some versions of Windows.

I have also intensified the debug messages (saved in extra/debug.txt). To a=
void that this file becomes too big it is cleared at the start of every cyc=
le. As a result you will have to copy the content (or rename the file) befo=
re restarting SlowJT9 if you want to keep the debug information.

If you still encounter problems (craches), please send me a copy of the deb=
ug file together with a description of the error (and if it can be provoced=
: the steps to do so) and your PC (COPU, memory, Win version).


Instead of making a new installation file I just uploaded the zipped execut=
able, it can be downloaded at http://472khz.org/SlowJT9/SlowJT9.zip .

Just unzip and replace the SlowJT9.exe file in the 0.9.11 installation fold=
er (default c:\SlowJT9).

The full 0.9.11 installation file can be downloaded at http://472khz.org/Sl=
owJT9/SlowJT9_setup.exe.


Be aware that due to the baudrate changes there is NO BACKWARD COMPATIBILIT=
Y for JT9-2 and JT9-5 to versions prior to 0.9.10.

In other words: JT9-2 and JT9-5 send with v0.9.11.1 cannot be decoded with =
versions v0.9.00 - v0.9.03 and vice versa.

The JT9-1 mode however is still the same and can be sent / received with al=
l versions (and is WSJT-X compatible).


All test reports, remarks, suggestions and opinions are most welcome.


I want to thank everybody who gave feedback, suggestions and bug reports ov=
er the past weeks, this was very much appreciated!


The next step is to check if the windowed sinc impulse response will improv=
e the performance and eventually implement it (big thank you to Marcus, DF6=
NM, for his help).

Once that is figured out I will focus on the implementation of a number of =
useful "extra's" as suggested by several hams.


?For now only a Windows version of SlowJT9 is available. But as the used ID=
E has cross platform facilities it should be possible to support other oper=
ating systems as well in the future.

73, Rik  ON7YD - OR7T
