I have set out to rewrite the WSPR Configuration tool in Python and tkinter for maximum portability, including MacOS, Linux, Windows, and just about anywhere else Python runs. The priority on portability drove the choice of Python and tkinter, since these usually do not require developers to look for and install a bunch of tools and libraries, and using these it can be quickly and easily packed into a single file for each target machine. After it is working and rather stable, I might include an automatic detection and use of Qt if it finds it already installed on the user's machine. Here is a screenshot of my progress so far. Some small details may not exactly match the current Windows version behavior, because [honestly] I never ran the Windows version. This was made to match the screenshot on the web page and using the documentation Harry provides on Github. The other tabs for the Signal Generator, Boot, and Serial configurations do not have screenshots of the latest version anywhere I could find, so I will do something that seems to make sense to me looking at screenshots from previous versions. Of course, this is all easily modified, so we can make it better, if there are any popular ideas. Once I get the remaining tabs complete, I will post the source on Github in the usual open source, community development manner. Thoughts?
