When you say you're sending "all 100's using COMPLEX_FLOAT32
interface", what exactly do you mean?  Do you mean the value 100 in
decimal repeatedly?  If so, this is a DC signal with no frequency
content, and DC offset correction could be wiping it out.  If not, can
you elaborate more on the data values that you're sending?
