Looks good. Although we may upgrade as well several issues we've identified previously.

Not sure if we want to change them now.

-The first is that the "divide" block is buggy and drops packets sometimes. So instead of having that "RMS-Multiply Cons-Add Cons-Divide" which acts as an AGC, just placing a normal GNURadio "AGC block": 77777 With (Rate 0.1)(Reference 0.7)(Gain 1.0)(Max gain 400000)

-Also, the NRZI block can be substituted by this whole combination: Screenshot from 2019-08-19 19-06-33 It's silly, but actually this chain consumes much less computing performance than the NRZI block...
