What do you mean by "loaded" and "installed"?

You must run the python code that matches the installed binaries. If
you switch from max to boatbod, you'd want to run the "install.sh"
script from the appropriate git repo (to install the binaries), then
make sure that you're using the corresponding python.

It's also possible that boatbod's recent change to support roaming is
a factor here.

In any case, the first step would be to run "./install.sh" in
~/gnuradio/bod/op25, then try rx.py again. If that doesn't help, it
may be a bug with that recent change. I haven't tried it myself yet.
