I'm getting a little closer...

it looks like I'm clipping a little bit, and is that "wide circle" effect a result of DC offset?

You're not being shunned :)

Stating the obvious, it would be great to have 1 complete
implementation of the C++ daughterboard code, rather than N partial
implementations.


Hopefully once I get passed my May madness I can work with Michael on this.

Does it look like I am clipping? I am not changing the transmitter between the two dumps. I figured the rx gain was too high but it seems

to be being set correctly.
