Dear EME Friends,
As mentioned in a Moon-Net posting about two months ago, I have been working on a version of WSJT that will offer a number of new user features.
I have made excellent progress since June. All of my meteor scatter and EME QSOs for the past six weeks have been made with a program version that will soon be available as WSJT6. During this time I have been gradually adding features, many of which had been suggested by other users. More features are still to come.
The present program version, v5.7.1, has the following capabilities that distinguish it from all earlier versions:
- Multi-threaded architecture for better sharing of CPU among tasks
- Built-in real-time waterfall display, usable in all WSJT modes
- DF of signal selectable directly from the waterfall display
- Selectable sound card
- Improved control of T/R timing
- Immediate decoding available after meteor "pings" in FSK441 mode
- No need to re-enter station parameters after a version upgrade
- 16-bit audio for better dynamic range
- User interface coded in the "Python" language^* (see below for more
programmer information)
Many other program enhancements are still to come:
- Correction for inaccurate sound-card sample rates
- Improvements to decoders for all WSJT modes
- Non-saturating measurements of signal level in JT65 mode
- More information saved in DECODED.CUM
- Optional logging of QSOs (for contests, etc.)
- Open source policy for nearly all program code
- Relatively easy to port program to Linux or Macintosh
Version 5.7.1 is stable and already very usable. However, some familiar features of version 4.x have not yet been implemented (e.g., CWID, EME Echo mode, ...); moreover, the new code certainly has bugs that will need to be traced down and corrected.
It will be very helpful to have some user input soon. Within the next week or so, I hope to make available a beta release of the most recent version. I will look forward to receiving your comments and suggestions.

*Additional information for programmers:
-----------------------------------------
Like all of us, I am not getting any younger. A time will surely come when I am unable to continue development of the WSJT program, or even to make sure that it will still work with the next generation of personal computers.
For these reasons, I very much want to encourage others who might be interested in becoming involved with future development of the program. I intend to release nearly all of the source code for WSJT under the GPL General Public License. (One piece of WSJT code has been licensed under a non-disclosure agreement; however, linking to the object code for this function will still be available to anyone.)
The user interface of the new WSJT is coded in the open-source language Python. The code makes use of Tkinter and a number of other freely available Python modules. Python was chosen because it is freely available, easy to learn and to program, creates attractive GUIs, and interfaces readily with compiled highly efficient languages such as Fortran and C. The audio I/O routines use PortAudio, a library of sound-card routines that can be used with Windows, Linux, Macintosh, and probably other platforms as well. The DSP functions (and indeed nearly all of the heavy-duty computations) are coded in Fortran. For all of these reasons, the new code will be easier to port to another platform when/if that becomes desirable.
