hackasatquals2020/GroundControlToMajorTom last gnuradio flowgraph not working

[whal-e3]

Hi 1064CBread!
Thank you so much for sharing your HAS writeups.

While following "GroundControlToMajorTom" challenge ,
the last flowgraph (figure_8.png) didn't give me the output(lyrics) like yours.
So I was wondering if you could share the config of "Constellation Object" settings.

Thank you!
