A couple of items:
1. The beta does not remember window size and look-n-feel settings on window closing.
2. Loop-back works but I get an ever increasing echo-back with faster and faster plus higher and higher pitch until I hit the stop button.
3. I could hear a QSO but they did not hear my TX. System said I was connected but no TX from me.
4, I would like to see audio RX/TX control sliders on the screen to allow me fast control of loud stations/systems. A TX audio bar graph meter would be nice to - to insure I'm not close talking the mic.
