Hi Arturo,

thanks for picking this up. I had done some python3 hacking on chirp
earlier this year, but apparently never pushed the changes anywhere
since they weren't working.

I confirm that my UV-5R works now as well. Cool.

Fwiw, I've tried to submit changes to the tracker on danplanet for
about half a dozen times and it always failed, so no idea where to
send my patches. If this mail gets through, the python3 patches are
there:

https://salsa.debian.org/debian-hamradio-team/chirp/-/tree/master/debian/patches

py3-print: print foo => print(foo) changes
py3-except: except Exception, e => except Exception as e changes
py3-fixes: the (small) rest

Only the UV-5R module is tested, there are many other issues remaining
in the other modules, but this is a start.

Thanks,
Christoph
