Tim K tagged this as, "probably-should-rewrite-for-3.8", "there-goes-my-weekend", and "I-blame-Zero".

[ZeroChaos-]

This is against 3.7 though, so.... :-)

[ZeroChaos-]

Hi @tkuester , so, about rewriting for 3.8 :-)

[tkuester]

@ZeroChaos- I just finished a first-pass rewrite for gnuradio 3.8 inside maint-3.8. I really should do some more QA work, and make sure the python has been properly ported to python3. It's not ready for prime time, but you should be able to compile it and confirm that the example .grc file runs still!
