What's in this update
- Optionally WinKey can generate CW immediately after paddle is hit. In this case PA/LNA PTT lead must be provided by footswitch or other PTT source.
- WinKey parameters "Keying compensation" and "1st extension" are controlled automatically now.
In the QSK mode the keying compensation and in the Semi Break-In mode the 1st extension are utilized to take account of new parameter T/R delay.
