Re: LF: JT9 buggy issues

[Roger Lapthorn <rogerlapthorn@gmail.com>]

Joe (et al),

In the end I deleted and reinstalled the r2695 version (the one on the WSPRnet page http://wsprnet.org/drupal/) and it appears to be stable here now.  If there are later versions I guess the link from the WSPRnet page should be updated regularly.

Is it possible to develop the JT9 mode to allow both QSO and beacon modes to co-exist? One of the issues currently is there are, arguably, too many different weak signal modes. If JT9-x could provide both QSO modes and beacon modes (with internet database linking), there is a likelihood that this would become the de-facto digital mode (other than CW) for all MF/LF purposes. 

BTW, G3XIZ was a good signal on 500kHz JT9-2 here sending G3XIZ TEST earlier. We hope to have a QSO very soon.

Here is from Joe, K1JT earlier today

"Many thanks for all the early feedback on WSJT-X, both on- and off-list.

A number of users have reported that PTT is not being properly released
when as transmission is finished.  I have not yet found a computer that
exhibits this problem... and needless to say, it did not arise for any
of us who made the first on-the-air tests.  For this reason, running
this bug down has not been easy.

If you have experienced this problem, please try replacing the wsjtx.exe
that you got with the download with one I have posted at
http://www.physics.princeton.edu/pulsar/K1JT/wsjtx.exe

Depending on the nature of the problem, this one might issue an error
message when it fails to turn off the PTT successfully.  Or it might
solve your problem, as it did for W7IUV.

One important note went out to the first testers, but was not in my more
open announcement.  This early program version may not properly
re-initialize all parameters when you change between JT9 submodes.  To
be sure, it's probably best to restart the program after changing modes.
 This will be fixed soon!

I see that despite these early teething problems, a number of QSOs are
being made tonight with JT9.  I look forward to hearing summaries of
your experiences!
