To: Users of WSJT
From: Joe Taylor, K1JT
Subject: WSJT 5.9.0
Date: November 14, 2005
I am pleased to announce that WSJT 5.9.0 is available for free
download from the WSJT Home Page,
http://pulsar.princeton.edu/~joe/K1JT. It should appear soon
on the European mirror site, http://www.dk5ya.de, as well.
I believe that all reported bugs found in beta-release version 5.8.6
have been fixed. In addition, new enhancements have taken the program
well beyond the capabilities of the baseline comparison versions,
4.9.8 and 5.8.6.
The new WSJT 5.9.0 is faster and better than previous versions in a
number of ways. A brief description of the enhancements since version
5.8.6 can be found at
http://pulsar.princeton.edu/~joe/K1JT/UpdateHistory.txt. There are
many program changes, so be sure to read this information carefully
before trying to use WSJT 5.9.0!
Of course there may be some new bugs, and perhaps I have overlooked an
existing problem that you already know about. Please let me know if
you find shortcomings in version 5.9.0, or if you have suggestions for
further improvements.
Sorry, I have not yet found time to implement EME Echo mode. When
that is done, and when I have finished some further enhancements to
the decoders, WSJT 6.0 will be born. With some luck, there may also
be a new User's Guide at about that time.
With best wishes,
-- 73, Joe, K1JT
Additional Information for Programmers
-----------------------------------------------------------------------
WSJT versions 5.8+ are the result of a complete re-write of the user
interface, timing control, and audio I/O portions of WSJT 4.9.8. My
principal motivation was to make the program multi-threaded, both for
real-time operational convenience and for performance reasons.
Another strong motivation was a desire to move the program away from
its dependence on a proprietary compiler (Microsoft Visual Basic) and
a single computer platform (Windows).
The user interface of WSJT 5.8+ is written in Python -- an elegant,
open, cross-platform language that has been a pleasure for me to
learn. The remainder of the program is written mostly in Fortran,
with some routines coded in C; much of that code has been carried over
directly from WSJT 4.9.8.
I hope soon to release the source code for WSJT under the GNU General
Public License (GPL). To this end, I have separated out the one piece
of proprietary code formerly in the program -- the soft-decision Reed
Solomon decoder licensed from CodeVector Technologies (CVT). A driver
for this decoder, optimized for JT65, has been compiled into a
stand-alone executable that is now distributed as part of the WSJT
installation package, but not part of the program itself. With this
approach I can honor all provisions of the CVT license, and at the
same time release everything else as an open source program under the
GPL.
WSJT 5.9.0 now includes an open source hard-decision Reed Solomon
decoder based on code written by Phil Karn, KA9Q . WSJT uses this
decoder automatically if the proprietary CVT decoder is unavailable.
In such instances the "deep search" decodes retain their full
sensitivity, but fully general decoding independent of the callsign
database will be less sensitive by 2 or more dB, depending on signal
fading characteristics. Separation of the program into two executable
units is transparent to the user.
WSJT 5.9.0 uses the following open source libraries, which are also
available under the GPL:
1. FFTW, by Matteo Frigo and Steven Johnson, for computing Fourier
transforms
2. "Secret Rabbit Code" or "libsamplerate", by Erik de Castro, for
accomplishing band-limited resampling of data
3. RS, by Phil Karn, KA9Q, for Reed Solomon encoding and
hard-decision decoding.
I hope that the open release of WSJT source code will encourage others
to read and understand the code, get involved in improving WSJT, and
perhaps porting it to other platforms. Versions of the CVT
soft-decision decoder for Linux or Macintosh will be easy to compile
and distribute, if there is demand for them.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Changes in WSJT 5.9.0 -- November 15, 2005
------------------------------------------
1. JT65 decoding has been made faster and significantly improved in
other ways. Three new options appear on the Decode->JT65 menu:
"Fast", "Normal", and "Exhaustive". The program is most sensitive
if you choose "Exhaustive". Choosing "Normal" will make decoding
slightly less sensitive, but the loss is not great, and decoding
can be twice as fast. The "Fast" setting is faster still, but can
be less sensitive by 2 dB or more in some cases. If you have a 1.5
GHz or faster computer, use "Exhaustive". With a slower computer
you may want to experiment with the other settings.
2. In JT65 mode, double-clicking on the waterfall (SpecJT window) or
on the red curve (main window) will set "Freeze DF" at the selected
frequency, turn Freeze ON, and invoke the decoder. Using this
feature, you can quickly decode a transmission at several different
values of DF. I find this feature to be *extremely* useful.
3. The range of DT values searched to establish synchronization has
been doubled, now extending from -2 to +10 seconds. The reported
values of DT are more accurate, as well. You should normally
expect EME signals to have DT in the range 2 to 3 seconds, but the
program will now synchronize properly even if DT is well outside
this range.
4. WSJT now offers the ability to correct for errors in soundcard
input and output sampling rates. Numbers displayed in the first
panel of the status bar (at lower left of the main screen) give the
ratio of actual sample rates for input and output to the correct
value, 11025 Hz. The numbers should stabilize about one minute
after program startup. If they fall in a "safe" range between
about 0.9990 and 1.0010, you have a good sound card (at least in
respect to sampling frequency). You can then leave the entry
fields "Rate In" and "Rate Out" on the "Setup -> Options" page at
their default values, 1.0.
If your soundcard gives one or both numbers well outside the safe
range, you should enter the displayed errant numbers as "Rate In"
and/or "Rate Out" on the Setup->Options page. This needs to be
done only once; subsequent changes in the last decimal place of the
displayed values are not very significant, and can be safely
ignored.
The result of this procedure is that your Tx signal will be
"trimmed" so that your tone spacings in time and frequency are
correct. In addition, your digitized Rx signals will be adjusted
so that the software can properly interpret them.
This is an important procedure. Some recent sound cards produce
sampling error factors as low as 0.9932 or as high as 1.0068. If
uncorrected, such results can degrade your S/N in WSJT modes by 2
dB or more.
If one of the measured sample rates differs from the corresponding
value specified for "Rate In" or "Rate Out" by more than 0.1%, a
red warning label will appear just below the graphical area on the
main screen.
5. Graphical display of information obtained during JT65 decoding has
been enhanced. As before, a red line illustrates the maximum
correlation between the pseudo-random sync tone pattern and the
received signal at each value of frequency offset, DF. A blue line
shows the correlation at the best DF, plotted as a function of time
offset, DT. If a shorthand message is detected, two new lines
colored magenta and orange replace the red and blue lines. The new
lines illustrate phase-resolved spectra measured in each of the two
phases of the shorthand square-wave pattern. A properly detected
shorthand message will show a peak in the magenta curve, followed
at a specified distance by a peak in the orange curve. The correct
locations of the two peaks are marked by small yellow ticks.
Unlike the alternating shorthand message tones, birdies will appear
approximately equally in the magenta and orange curves.
6. For the convenience of temporary DXpeditions, a new JT65 feature
permits use of add-on DXCC prefixes that are not in the published
list of supported prefixes. Both stations in a QSO must enter the
required prefix (for example, PJ8 or FS) in a box on the
Setup->Options page. The effect will be to temporarily add the
entry to the table of supported prefixes.
7. The Setup->Options page has new entry fields labeled "Source RA"
and "Source DEC". You can enter the current right ascension and
declination of a radio source to be used for system calibration, or
perhaps a pulsar or a deep space probe that you wish to detect.
The program will display (on the Astronomical Data screen) the
current Azimuth and Elevation of the specified object at your
station. The source Azimuth and Elevation are also written every
second to the file azel.dat, in case you have automated tracking
capabilities that depend on this information.
8. To facilitate the coming release of the full source code of WSJT
under the General Public License, the proprietary soft-decision
Reed Solomon decoder has been removed from WSJT proper and made
into a separate executable module. This change is invisible to the
user, and the full benefit of the soft-decision decoder is still
available. An open source hard-decision decoder is also provided;
it's what you get when you select the "Fast" JT65 decoding option.
9. In WSJT 5.8.6, if the value of "Freeze DF" (as displayed in the
Status Bar) differs from the sync tone frequency by more than
"Tol", shorthand decoding was suppressed even if Freeze was not
checked. This is a bug, and it has been fixed.
10. Earlier versions of WSJT also had a bug that could cause the "Zap"
function to notch out a valid sync tone. Fixed.
11. The Help screens called up by F1 and Shift-F1 have been updated.
Be sure to read these screens: they contain many operational
conveniences that you may not have discovered!
12. At scrolling speed 5, the time labels and "minute separator" lines
were displayed erratically and the CPU load was excessive. Fixed.
13. Signal strength measurements above -20 dB were formerly compressed
and significantly underestimated. This has been fixed.
14. Decodings of the average of many properly synchronized transmissions
would sometimes go from "good" to "bad" after approximately 8-12
transmissions. This was a bug, and it has been fixed.
15. Several bugs in the FSK441 decoder have been fixed. Both automatic
decoding and mouse-picked decoding have been improved.
16. Changing WSJT modes now sets Auto to OFF, Tol to 400, and the Tx
message number to 1.
17. The generated audio tones for CW ID in FSK441 and JT6M modes have
been moved down to 440 Hz, to avoid possible confusion with the
other tones used in these modes.
18. Readout of "Rx noise" on the main screen is now highlighted in red
if the level is outside the range -10 to +10 dB.
19. The Monitor button is no longer highlighted in green while you are
transmitting.
20. No attempt is made to decode if the Rx level is very low -- for
example, if your receiver is turned off.
21. If the Grid box does not contain a valid locator, readouts of
azimuth and distance are suppressed.
22. Keying of the audio tone to produce Morse code has been "softened"
to suppress key clicks.
23. Your transmitted messages recorded in the file ALL.TXT are now
identified as to mode, and shorthand transmissions are noted.
23. A number of other very minor bugs have been fixed.

1 Introduction
WSJT is a computer program designed to facilitate Amateur Radio
communication under extreme weak-signal conditions. Three very
different coding and modulation methods are provided: one for
communication by "meteor scatter" techniques on the VHF bands; one for
meteor and ionospheric scatter, primarily on the 6 meter band; and one
for the very challenging EME (Earth-Moon-Earth) path.
2 Program Overview
WSJT's user interface is written in Python. The major Python
source-code files include:
1. wsjt.py Defines the main-screen GUI for user interactions;
acts as "traffic cop" for orchestrating all
event-driven and time-shared activities.
2. specjt.py Provides real-time display of received signals as
two-dimensional "waterfall" spectra.
3. options.py Provides entry fields for user-defined parameters.
4. astro.py Displays astronomical data for sun, moon, sky
temperature, etc.
Smaller Python files serve various utility purposes.
Both wsjt.py and specjt.py make calls to external procedures compiled
from Fortran and C. A variety of global data is shared among modules
through common blocks defined in Fortran. The Python code runs in a
single thread, although timers make the functions of the several main
modules appear concurrent. Fortran routines create additional threads
to be used for soundcard I/O and the decoding of received messages.
As a small part of its overall task, the decoder for JT65 invokes an
external program named KVASD.EXE or KVASD, located in the main
WSJT directory. If this program is present it uses information on
received 64-FSK symbols and attempts to decipher it according to a
Reed Solomon (63,12) code, using the algebraic soft-decision algorithm
of Koetter and Vardy. If KVASD is not present, WSJT uses its own
internal hard-decision Reed Solomon decoder instead. Interprocess
communication between WSJT and KVASD takes place through a shared disk
file. KVASD is not an integral part of WSJT. Its algorithm is
patented, and the source code is the property of CodeVector
Technologies, LLC. However, compiled versions of KVASD may be freely
used in conjunction with WSJT for the purposes of amateur radio
weak-signal communication.
3 Some Functional Details
WSJT execution starts at the top of Python file wsjt.py. The
other Python modules are loaded and executed as needed. Fortran
routines are called to start a high-priority thread to handle
continuous A/D and D/A streams, and a background thread to decode
received or previously recorded signals. The top-level Python
code determines the overall state of program operation, e.g.,
Idle, Monitoring, or Transmitting. In normal usage the operator
puts the program into Auto mode, resulting in a timed sequence of
alternating transmission and reception intervals.
4 Other Open-Source Software used in WSJT
WSJT 5.9 uses the following open source libraries:
1. FFTW, by Matteo Frigo and Steven Johnson, for computing Fourier
transforms
2. PortAudio, by Ross Bencina and Phil Burk, for audio I/O
3. "Secret Rabbit Code" or "libsamplerate", by Erik de Castro, for
accomplishing band-limited resampling of data
4. RS, by Phil Karn, KA9Q, for Reed Solomon encoding and
hard-decision decoding.
5 Platform-Dependent Notes
The Python code should run on any supported Python platform. Most of
the remaining code can be recompiled for Linux or OS/X, instead of
Windows. Platform-dependent versions of FFTW, PortAudio, and
libsamplerate need to be installed.
Methods are provided for creating additional threads and setting their
runtime priorities in both Windows and Linux.

7 Compiling Instructions
Scripts are provided for compiling WSJT in both Windows and Linux.
They are presently set up to use Compaq Visual Fortran (v6.6) and
Microsoft C (v6.0) in Windows, and g95 and gcc in Linux. My
installation has Python 2.3. Additional tools include f2py, which
compiles Fortran and C to make Python extensions; the Python Imaging
Library; Numeric Python; and the SciPy distribution utilities.
Linux Windows Function
-------------------------------------------------------------------
g0 g0.bat Compiles the hard-decision Reed Solomon Decoder
Needs to be done only once.
g1 g1.bat Compiles the remaining Fortran and C to produce Python
extension module audio.pyd (Windows) or audio.so
(Linux).
g2.bat Uses McMillan Installer to create an f2py specification
file, wsjt.spec
g3.bat Uses Installer to produce a distributable file WSJT6.EXE
(Windows).
The final two build steps have not yet been tried in Linux. In Windows,
these steps produce a distributable file WSJT6.EXE that contains all
necessary software components, so that the user does not need to install
Python or any of its other extensions.
8 Present status (December 20, 2005)
WSJT version 5-9-2d is fully functional in Windows. The Linux version
can be used to decoded recorded files, but real-time audio I/O has not
yet been implemented.

SUBROUTINE FOUR2a (DATA,N,NDIM,ISIGN,IFORM)
C Cooley-Tukey fast Fourier transform in USASI basic Fortran.
C multi-dimensional transform, each dimension a power of two,
C complex or real data.
C TRANSFORM(K1,K2,...) = SUM(DATA(J1,J2,...)*EXP(ISIGN*2*PI*SQRT(-1)
C *((J1-1)*(K1-1)/N(1)+(J2-1)*(K2-1)/N(2)+...))), summed for all
C J1 and K1 from 1 to N(1), J2 and K2 from 1 TO N(2),
C etc, for all NDIM subscripts. NDIM must be positive and
C each N(IDIM) must be a power of two. ISIGN is +1 or -1.
C Let NTOT = N(1)*N(2)*...*N(NDIM). Then a -1 transform
C followed by a +1 one (or vice versa) returns NTOT
C times the original data.
C IFORM = 1, 0 or -1, as data is
C complex, real, or the first half of a complex array. Transform
C values are returned in array DATA. They are complex, real, or
C the first half of a complex array, as IFORM = 1, -1 or 0.
C The transform of a real array (IFORM = 0) dimensioned N(1) by N(2)
C by ... will be returned in the same array, now considered to
C be complex of dimensions N(1)/2+1 by N(2) by .... Note that if
C IFORM = 0 or -1, N(1) must be even, and enough room must be
C reserved. The missing values may be obtained by complex conjuga-
C tion.
C The reverse transformation of a half complex array dimensioned
C N(1)/2+1 by N(2) by ..., is accomplished by setting IFORM
C to -1. In the N array, N(1) must be the true N(1), not N(1)/2+1.
C The transform will be real and returned to the input array.
C Running time is proportional to NTOT*LOG2(NTOT), rather than
C the naive NTOT**2. Furthermore, less error is built up.

SUBROUTINE FOUR2a (a,nfft,NDIM,ISIGN,IFORM)
C IFORM = 1, 0 or -1, as data is
C complex, real, or the first half of a complex array. Transform
C values are returned in array DATA. They are complex, real, or
C the first half of a complex array, as IFORM = 1, -1 or 0.
C The transform of a real array (IFORM = 0) dimensioned N(1) by N(2)
C by ... will be returned in the same array, now considered to
C be complex of dimensions N(1)/2+1 by N(2) by .... Note that if
C IFORM = 0 or -1, N(1) must be even, and enough room must be
C reserved. The missing values may be obtained by complex conjuga-
C tion.
C The reverse transformation of a half complex array dimensioned
C N(1)/2+1 by N(2) by ..., is accomplished by setting IFORM
C to -1. In the N array, N(1) must be the true N(1), not N(1)/2+1.
C The transform will be real and returned to the input array.
