The installation file for WSJT-X version 0.4, revision 2731 has been 
posted at

http://physics.princeton.edu/pulsar/K1JT/WSJTX_04r2731.exe

In this revision a number of known bugs have been fixed, and the JT9 
decoder is significantly improved.  Among other improvements, the 
program is now much less fussy about timing issues.

My "To Do" list for WSJT-X is far from empty -- for example, many 
user-convenience features are yet to be implemented.  However, in its 
present state WSJT-X performs well and will enable you to make QSOs at 
signal levels down to those specified on the last page of the User's Guide:
http://physics.princeton.edu/pulsar/K1JT/WSJT-X_Quick_Start_Guide.pdf


In some circumstances the present decoder will seem slow.  Speed 
enhancements are yet to come.  In the meantime, you will find it best to 
set "Tol" (the frequency tolerance parameter) to a value only a few 
times the width of the desired JT9 signal.

I have now made many QSOs with JT9-1 on 160 m, often with inaudible 
signals.  I look forward to working you on that band soon!  I also hope 
to have good receiving systems soon for 137 and 472/500 kHz: maybe we 
can work cross-band?  A number of us have been coordinating our activity 
on the K3UK Sked Page: go to
http://www.obriensweb.com/sked/ and then click on "digitalradio" at the 
upper right.

As always, your feedback on WSJT-X will be greatly appreciated!  I'll do 
my best to fix reported bugs quickly.  During this testing period, 
please remember to run the program with "Save All" checked, and send me 
examples of *.wav files on which the decoder behaves poorly.
