I have some good news. Thanks to Dave W1HKJ there is now a Windows alpha version available.
I have a short description of the new functionality and download link available here:
Once again, this is an alpha release provided in order to get some feedback and improvement ideas from FLDIGI users. You can provide feedback by submitting comments below (in the blog) or sending me email to ag1le at innomore dot com. It would be very helpful if you could provide audio samples (WAV files can be recorded using File / Audio / RX Capture feature of FLDIGI), screenshot of what CW parameter settings you are using and general description of the problem or issue you discovered.
