Quoting op25 at zellners.com:
> For OP25-boatbod is this Python 3.7 compatible??????

After doing an apt-get install for python3-waitress

Then rerun rx.py

It fails on the import for httplib

And from what I see from 2.7 to 3.x httplib is now http.client so all  
the calls for that are now changed....

So I am going to guess that any further attempts to add in the python3  
packages needed will still fail to get OP25-boatbod to run till this  
any other ABI changes are made...
