Changes in WSJT 5.9.2: January 16, 2006
|
|
---------------------------------------
|
|
|
|
Enhancements
|
|
------------
|
|
|
|
1. Thread priorities have been adjusted for smoother operation.
|
|
|
|
2. The JT65 decoder has been giver improved immunity to garbage data
|
|
(birdies, QRM, etc). It exhibits better performance on strong
|
|
signals and provides more accurate estimates of their S/N.
|
|
|
|
3. The FSK441 decoder produces less on-screen gibberish when
|
|
processing 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.
|
|
(This feature is also useful in JT65 mode.)
|
|
|
|
5. On-screen font sizes can be set by using Windows Notepad 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 font 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 for testing purposes. 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 example to test the decoder or to practice
|
|
operating in JT65 mode. You can even have the two computers "work
|
|
each other" in a simulated QSO, 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 status between the WSJT and SpecJT
|
|
screens.
|
|
|
|
10. You can use the Alt-F and Alt-Z keyboard shortcut to toggle
|
|
"Freeze" and "Zap" on and off.
|
|
|
|
11. "Accelerated decoding" has been removed from the Setup menu. In
|
|
effect, this option is now always ON.
|
|
|
|
12. Text windows are now cleared when switching between modes.
|
|
|
|
13. Linux and FreeBSD versions (see below) offer PTT control via
|
|
parallel port, as well as serial port. They offer sound support
|
|
via ALSA and OSS.
|
|
|
|
Bug Fixes:
|
|
----------
|
|
1. The use of non-threadsafe code for FFTs could cause 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.
|
|

|
For Curious Users, and Especially for Programmers
|
|
-------------------------------------------------
|
|
|
|
WSJT is no longer a one-person effort, and the program no longer runs
|
|
only under Microsoft Windows. WSJT is now 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. Porting WSJT to the Macintosh platform should be
|
|
straightforward, as well, although the development team does not
|
|
yet include anyone with Macintosh hardware.
|
|
|
|
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! We
|
|
could use help with documentation and website maintenance, as well as
|
|
actual programming.
|
|
|
|
The present WSJT working group consists of:

Diane Bruce, VA3DB
