[Discuss-gnuradio] signal distortion in simple code

[cswiger]

Gang - can anybody shed some light on my problem, it's a very
simple script that has me pulling out hair.   The situation is
laid out on this page:

and is why is the real world signal all broken up while the
software generated signal perfect?  The signal generator and
ADC are all working fine! I must be overlooking something.

Any tips appreciated.
