Jay, thanks again for the decode: congrats for your rx setup.
And thank you so much for trying, Rob.

Here, the TP2 reference signal (not sufficiently filtered) overshot som= etimes the quadrature divider (x4) causing that phase jumps. The problem is n= ow fixed.

A new TX EbNaut session is scheduled for starting tomorrow evening.
