Ok, i will try it. But here is another question. This looks like some kind of clipping as you said it, and from signal processing, I remember that there were some sort of Millican Terms (can be millian too, can`t figure out right now) with %9 overshoot at the edges of a rectangular signal (resulting from the addition of many sinusiodal signals). Well if that signal is coming out at my receiver, (and i am not sure of it too) what could be the reasons?
