So I got the BER to drop by aligning the two streams, but when I look at both bit streams on the scope they do not look aligned. So I am confused! See attached images.
It is working, I am able to adjust the noise level now and watch the BER drop. But I do not understand this. Can anyone shed some light on this?
Thanks so much for the help so far!!

It is important that you have a time scope where you compare the initial bit stream with the output of the demodulator.
These are NOT synchronized.
Unless you do that you cannot get any meaningful measurement of the BER!
You can substitute the Qt blocks with WX blocks. This is easy.
