Changes in WSJT 5.9.5 (r236): August 3, 2006
---------------------------------------------
WSJT v5.9.5 r236 contains some major improvements for JT65 and a
number of smaller enhancements affecting other modes.
1. Changes to the JT65 Deep Search decoder have made it slightly more
sensitive, on average. More importantly, the number of false
decodes has been dramatically reduced. JT65 decoding can be as
much as 3 times faster than before. For these reasons alone, you
should be sure to upgrade if you use JT65.
2. A more useful menu of JT65 decoding options is provided. You may
now select "No Deep Search", "Normal Deep Search", "Aggressive Deep
Search", or "Include Average in Aggressive Deep Search".
3. The two end-of-line numbers (formerly displayed only if Aggressive
was checked) are now always displayed in JT65 mode. The first
number is 1 if the Koetter-Vardy decoder succeeded, 0 otherwise.
The second number is the confidence level of the Deep Search
decoding (if enabled) on a 0 to 10 scale.
4. The JT65 AFC function has been rewritten. Drifting signals
(including Doppler-induced drifts at 1296 MHz) will usually decode
better with AFC turned on.
5. Mode JT65C, which is used primarily at 1296 MHz, has been improved
in several ways. Synchronizing is better by about 1 "sync" unit,
and signal strengths are measured more reliably. Decoding of
shorthand messages is improved.
6. When compiled for Linux and FreeBSD (see note below), WSJT now
allows use of parallel as well as serial ports for T/R control.
7. Wave files are now saved correctly in Linux and FreeBSD versions.
8. Support has been added for extra-long callsigns such as
VU4AN/VU3RYF. The full augmented callsign must be no longer than
12 characters. Enter the special add-on DXCC prefix or callsign
(in this case, VU4AN) on the Setup | Options page.
9. If the "Grid" box on main WSJT window is blank, displayed values of
Doppler and df/dt will be those of your own echoes.
10. If the ToRadio box is blank, "Mon_" (rather than "_" is now used
as the naming prefix for recorded wave files.
11. The birdie-killing "Zap" feature has been changed so that if
Freeze is ON, nothing is zapped within Tol of the Freeze DF. In
addition, the Zap behavior no longer depends on previous decoding
history.
12. Bug fix: previously, if Freeze had been checked while operating in
another mode, Zap no longer worked correctly in FSK441 mode. This
has been fixed.
13. The selection of data for mouse-picked decodes in JT6M mode has
been corrected. (In recent versions it was necessary to click a
few seconds to the right of a signal enhancement.)
14. The logic that limits search for JT6M synchronization to a range
of frequencies (+/- Tol around FreezeDF) has been corrected. A
small green tick at the left edge of the main graphical area
indicates the FreezeDF frequency. The FreezeDF value is also
displayed digitally in the status bar. You can change FreezeDF
with the left/right keyboard arrows. Default settings for JT6M are
now Tol=200, Freeze On, MouseDF=0.
15. If mouse-picked decoding was invoked, all wave files were
previously saved even if "Save none" was selected on the menu.
This has been fixed.
16. On your first start-up with version 5.9.5, be sure to re-enter
your correct PTT port number on the Setup | Options page. Under
Linux or FreeBSD, enter the appropriate device name, for example
/dev/ttyS0.
Special note to Linux and FreeBSD users
---------------------------------------
WSJT is now being used by a number of people on Linux or FreeBSD
systems. Appearance and operational behavior is essentially identical
to the Windows version. At present you must compile the yourself for
Linix or FreeBSD. Instructions are available, and others who have
succeeded will help you if help is needed. This is not necessarily a
trivial task, however.
Packaged versions of WSJT for specific *nix distributions may be
provided if there is sufficient demand.
For more information on WSJT for Linux and FreeBSD, or if you want to
try compiling the program for Mac OS/X, contact the WSJT development
team at wsjt-devel@lists.berlios.de.
WSJT is Open Source software. The source code and related materials
can be found at http://developer.berlios.de/projects/wsjt/.
Changes in WSJT 5.9.4 (r159): April 11, 2006
---------------------------------------------
This is a maintenance release.
1. Problems exhibited on some computers with dual or "hyperthreading"
CPUs have been fixed (or at least reduced, see below).
2. Problems with reading previously recorded files (such as the sample
files in the WSJT tutorial) have been fixed.
3. Bad data could cause an error message "Error in KV decoder, or no
KV decoder present" in the console window. Fixed.
4. The delay between PTT assertion and start of Tx Audio, and the
delay between end of Tx Audio and release of PTT, have been increased
by 0.2 s. In addition, a bug in the T/R timing logic was fixed.
5. There was a minor bug in computing the position of the moon. (The
displayed Az and El of the "home station" were correct for a time 100
seconds earlier than the actual time.) This has been fixed. In
addition, refraction adjustments are no longer made in the Sun and
Moon elevations.
6. A minor bug when displaying large negative Doppler shifts in the
file azel.dat has been fixed.
7. As an aid to future development of WSJT, the program is now capable
of transmitting "test files" with arbitrary audio content.
NOTE: If you have a computer with multiple CPUs or a CPU with
hyperthreading, and if WSJT 5.9.4 does not run properly for you,
please reboot your machine, enter the BIOS Setup screen, disable
hyperthreading, and see if WSJT then runs properly. Then let me know
the results of this test. Note: you will probably notice very little
(if any) degradation in performance by leaving hyperthreading turned
off. For now, this is the recommended procedure if you have problems
with it turned on.
Changes in WSJT 5.9.3: January 26, 2006

2. The occasional error message about "images do not match" has been
trapped and should no longer occur.
3. Code that required one's own grid locator to be entered with first
two letters in upper case, last two in lower case, has been made
case insensitive (as it should have been).
3. It is no longer necessary to enter one's own grid locator with the
first two letters in upper case and the last two in lower case.
4. Initialization of the PTT line to the "OFF" state has been fixed.
