Re: [Discuss-gnuradio] How to stop GRC flowgraph after a defined time

Within the gnuradio source tree, https://github.com/gnuradio/gnuradio .
Where they've been installed depends on your system, but you'd
typically look in places like
/usr/[local/]lib[64]/python2.7/{site,dist}-packages/gnuradio

Note that most of the blocks that come with GNU Radio aren't written in
Python, but C++.

Best regards,
Marcus
