Hi Warren
Works OK for me, two XP SP3 machines.
Now on JT9-2 testing.

Hello the list,
I have installed WSJT-X from Prof. Taylor's web site on my Win XP machine.
When I click on the WSJT-X icon I get a pop-up "Error starting or
running program C:\Program Files \wsjtx\jt9-s "
and then the Windows error reporting box pops up.
Do I need something other than Windows XP Professional Service pack 3 ?
73& tnx!

A new revision of the experimental program WSJT-X has been posted. As
usual, a link to it appears on the WSJT web site:
http://physics.princeton.edu/pulsar/K1JT/wsjt.html
The following is a direct link to the installation file:
http://physics.princeton.edu/pulsar/K1JT/WSJTX_05r2783.exe
This revision has an unusually large number of changes relative to the
previous release, v0.4 r2746. These changes include:
1. PTT control via COM ports COM10 and higher is enabled.
2. Improved decoder performance: higher speed as well as better chances of
success. Moderate amounts of frequency drift are detected and compensated.
Computed S/N values are more reliable. Time offsets from -2.5 to +5 s are
now supported, which makes JT9 usable for EME. (EME tests on 144 MHz have
been successful, and performance on that propagation mode appears to be
good.)
3. Tx Frequency now tracks the selected QSO Frequency (unless you hold down
the CTRL key when setting QSO Frequency via mouse-clicks or the F11/F12
keys).
4. Decoded text containing "CQ " is highlighted with green background; text
including "MyCall" is highlighted in red.
5. In previous versions, signal reports were required to be in the range -30
to -01 dB. In v0.5 r2782 the range has been extended to -50 to +49 dB.
There is backward compatibility for the range -30 to -01, but reports in the
range -50 to -31 and 0 to +49 will NOT be decoded correctly by previous
program versions. It is important to upgrade!
6. Items "Save Synced" and "Save Decoded" are now implemented.
7. UTC Date, JT9 submode, and a parameter related to the decoding procedure
are now included in file wsjtx_rx.log.
8. Editing of Tx messages (in any of the six Tx message boxes) is complete
when you hit "Tab" or "Return". The message is then parsed and converted to
the form in which it will be displayed if decoding is successful. Free-text
messages are trimmed to 13 characters and highlighted with a pink
background.
9. The most recent transmitted message is displayed in the right-most label
on the status bar. This can be useful if you have lost track of where you
were in a QSO.
10. By default, the program now starts with Monitor ON. An option on the
Setup menu allows you to select "Monitor OFF at startup".
11. Better scaling is provided for the red "JT9 Sync" curve. Note that JT9
signals in the active sub-mode should appear in this plot as a bump of width
equal to the total signal bandwidth, with a narrow and slightly higher bump
at the left edge. The narrow bump is the frequency of the Sync tone, which
is defined as the nominal frequency of the JT9 signal.
12. Basic QSO information is now written to file wsjt.log when you click the
"Log QSO" button.
13. The WSJT-X User's Guide has been updated.
14. Other known bugs have been fixed. There will probably be new ones!
When you find one, or if you know of any old ones that have NOT been fixed,
please send me email.
Summary of Present Status
----------------------------------------------------------------------
I believe that WSJT-X is now a stable and very usable program. Many
thousands of QSOs have been made with JT9-1, mostly at HF -- I have made
nearly 100, myself. Also a number of QSOs have also been completed at MF,
and successful tests have been made on 2m EME, etc. A number of QSOs have
also been made with JT9-2.
As far as I know the slower modes (JT9-5, JT9-10, and JT9-30) also work
correctly. (Certainly they do in my laboratory test setup.) Most people
will find these modes too slow for "everyday" use, and they require high
frequency stability. It remains to be seen whether they will be widely
used.
An alternative approach to obtaining improved sensitivity would be to give
the decoder an ability to average over several successive transmissions.
For example, the average of five JT9-1 transmissions could reach a decoding
threshold around -32 dB, only 2 dB worse than a single JT9-5 transmission.
Because of QSB, the shorter transmissions may actually succeed in less total
time. Stability requirements would be those of JT9-1, much less stringent
than those of JT9-5.
Program development is not finished, by any means. I will be grateful for
your feedback on performance issues, as well as your "wish-list" of features
to be added. As always, example recordings of files that you think should
have decoded, but did not, will be much appreciated.
I hope to find time for more work on WSJT-X soon. Later this week, however,
my radio time will be focused primarily on the ARRL International EME
Contest.
With best wishes,
