Thanks Glen, By the way those views are via the freedv spectrum display.
What I was thinking was the random numbers are of course hitting all the tones equally, whereas the vocoder bits are not as pure, and may in fact favor bit combinations over another. Maybe a sequence of the same bit patterns. I'm wondering if I need to create a transmit filter before the D/A. It being a lot less sophisticated than a sound card.
