All

There is a new, improved FLDIGI alpha build available with multichannel CW decoder feature in http://www.w1hkj.com/ag1le/.
Windows binaries are in file  fldigi-3.21.83cw-a5_setup.exe and source code tarball in file fldigi-3.21.83cw-a5.tar.gz

I fixed a number of bugs and did also a few improvements in this cw-a5 version,  namely:
-  timeout - remove found CW signal from Signal Browser after a timeout period. Timeout value is set in UI/Browser control panel
- matched filter - for each channel create filters matched with Morse speed. This feature can be turned on / off using the Modem/CW control panel.
- find_signals improvement. Improved the algorithm that finds the CW signals from FFT spectrum. Should produce less misidentified signals for given threshold value.

Please give it a try and provide feedback on the multichannel CW functionality. Thanks for the all people who have already provided feedback and new feature ideas.
