Changes in WSJT 5.9.2: January 10, 2006
|
|
---------------------------------------
|
|
|
|
Enhancements
|
|
------------
|
|
|
|
1. Thread priorities have been adjusted for smoother operation. One
|
|
result is that there will be fewer audio glitches caused by the
|
|
Windows O/S paying attention to other programs.
|
|
|
|
2. The JT65 decoder now has improved immunity to "garbage data," and
|
|
it exhibits better performance on strong signals.
|
|
|
|
3. The FSK441 decoder produces less on-screen gibberish when you do
|
|
mouse-picked decodes.
|
|
|
|
4. The JT6M decoder now makes better use of Freeze and Tol. You can
|
|
set the value of "Freeze DF" by using the Right/Left arrow keys.
|
|
|
|
5. On-screen font sizes can be set by using Windows Notepad (or
|
|
another text editor) to edit the file wsjtrc.win. If your screen
|
|
has resolution greater than 1024 x 768, or if you have old eyes
|
|
like mine, you may want to increase the sizes from 8 and 9 points
|
|
(first three lines of the file) to, say, 9 and 10 points.
|
|
|
|
6. A simulator mode is now built into WSJT. It is presently most
|
|
useful in JT65 mode. By entering, say, "#-22" in the text box for
|
|
Tx6, you signify that the program should generate its Tx audio
|
|
files with the signal embedded in white gaussian noise, 22 dB
|
|
below the noise power in a 2.5 kHz bandwidth. You can direct this
|
|
signal into a second computer running WSJT, for eaxmple to test
|
|
the decoder or to practice operating in JT65 mode. You can even
|
|
have the two computers "work each other", although changing
|
|
messages of course requires operator action.
|
|
|
|
7. Dividing lines are now provided on the waterfall display between
|
|
spectra corresponding to wave files read from disk.
|
|
|
|
8. The PTT line is explicitly set low on program startup.
|
|
|
|
9. The F10 key brings up the SpecJT screen (if it was hidden) and
|
|
toggles foreground and focus between the WSJT and SpecJT screens.
|
|
|
|
10. You can use the Alt-F keyboard shortcut to toggle "Freeze", and
|
|
Alt-Z to toggle "Zap".
|
|
|
|
11. "Accelerated decoding" has been removed from the Setup menu. In
|
|
effect, it is now always ON.
|
|
|
|
|
|
Bug Fixes:
|
|
----------
|
|
1. The use of non-threadsafe code for FFTs caused occasional and
|
|
unpredictable program crashes. Fixed.
|
|
|
|
2. A bug in the JT65 decoder could (rarely) cause large errors in the
|
|
reported level of strong signals. Fixed.
|
|
|
|
3. The program could be made to crash by trying to read a very short
|
|
wave file. Fixed.

Information for Programmers
|
|
---------------------------
|
|
|
|
WSJT is no longer a one-person effort and no longer runs only in
|
|
Microsoft Windows. It has become a full-fledged Open Source project,
|
|
with an active working group making contributions to future
|
|
development. Source code is now stored in a public repository under
|
|
control of a version control system called Subversion, or SVN. You
|
|
can learn more at http://developer.berlios.de/projects/wsjt/.
|
|
|
|
The first significant result of the group effort has been to create
|
|
versions of WSJT that run under the Linux and FreeBSD operating
|
|
systems. If you are interested in testing and using WSJT on your own
|
|
Linux or FreeBSD system, we'd like to hear from you.
|
|
|
|
If you feel that you can usefully contribute to the future development
|
|
of WSJT on any platform, we would also like to hear from you!
|
|
|
|
The present WSJT working group consists of:
|
|
|
|
Diane Bruce, VA3DB
|
|
James Courtier-Dutton
|
|
Bob McGwier, N4HY
|
|
Stewart Nelson, KK7KA
