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.

|
|
||||||
install: g95
|
|
||||||
|
|
||||||
follow instruction File: Install
|
|
||||||
|
|
||||||
How to install g95:
|
|
||||||
|
|
||||||
File Install:
|
|
||||||
1) Unpack the downloaded tarball (e.g. g95-x86-linux.tgz) in a directory
|
|
||||||
of your choice:
|
|
||||||
|
|
||||||
tar -zxvf g95-x86-linux.tgz
|
|
||||||
|
|
||||||
2) For your convenience, you can create another symbolic link from a
|
|
||||||
directory in your $PATH (e.g. ~/bin) to the executable
|
|
||||||
|
|
||||||
ln -s $PWD/g95-install/bin/*g95* ~/bin/g95
|
|
||||||
|
|
||||||
|
|
||||||
You should now be able to run g95 and create executables.
|
|
||||||
To get a list of environment variables that control the library, run a
|
|
||||||
compiled binary with the --help option, ie:
|
|
||||||
|
|
||||||
./a.out <20>help
|
|
||||||
|
|
||||||
From console try the g95 command .
|
|
||||||
The system should answer
|
|
||||||
g95: no input files
|
|
||||||
|
|
||||||
|
|
||||||
I changed the SymLink to /usr/bin where i installed the g77 packages too
|
|
||||||
ln -s $PWD/g95-install/bin/*g95* /usr/bin/g95
|
|
||||||

WSJT DEVELOPMENT OVERVIEW
|
|
||||||
-------------------------
|
|
||||||
|
|
||||||
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 compiled for Linux, FreeBSD, unix, or OS/X,
|
|
||||||
as well as Windows. Platform-dependent versions of FFTW, PortAudio,
|
|
||||||
and libsamplerate may need to be installed.
|
|
||||||
|
|
||||||
Methods are provided for creating additional threads and setting their
|
|
||||||
runtime priorities in Windows, Linux, and FreeBSD.
|
|
||||||

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 g2.bat Uses McMillan Installer to create an f2py specification
|
|
||||||
file, wsjt.spec
|
|
||||||
g3 g3.bat Uses Installer to produce a distributable file WSJT6.EXE
|
|
||||||
(Windows).
|
|
||||||
g99 g99.bat Runs all of the g[0-3] scripts.
|
|
||||||
|
|
||||||
These steps produce a distributable file WSJT6.EXE (Windows) or wsjt6
|
|
||||||
(Linux) that contains all necessary software components, so that the
|
|
||||||
end user does not need to install Python or any of its other
|
|
||||||
extensions, or the compilers.
|
|
||||||
|
|
||||||
A configuration script and Makefile facility is also provided.
|
|
||||||
Assuming that all of the pre-requisites are properly installed, WSJT
|
|
||||||
can now be compiled in Windows as follows:
|
|
||||||
|
|
||||||
C> copy Makefile.win Makefile
|
|
||||||
C> nmake
|
|
||||||
|
|
||||||
In Linux or FreeBSD, do the following:
|
|
||||||
|
|
||||||
$ ./configure --enable-portaudio (or --enable-alsa or --enable-oss)
|
|
||||||
$ make
|
|
||||||
|
|
||||||
|
|
||||||
8 Present status (January 17, 2006)
|
|
||||||
----------------------------------------------------------------------
|
|
||||||
|
|
||||||
WSJT version 5.9.2 (built from SVN revision 115) has been released for
|
|
||||||
Windows. It is is fully functional in Linux and BSD, as well, but
|
|
||||||
presently need to be compiled locally. In due course we plan to
|
|
||||||
provide distributions for standard *nix distributions.
