This is interesting to me. I have had problems with my firebox/SDR setup on CW for all software versions after 1.4 preview 16. After that time I would get something that sounded like a square wave and would drive my PA to between 130 and 145 watts. This would happen intermittently, like ever 10th time I would go from RX to TX. Sometimes it would occur a couple times in a row and sometimes not for many transmissions. I think what ever is going on here is related to this issue. Was the "hard clipper" imp lamented after pre 16? Pre 16 is rock solid and does not show this behavior.
