Hi Anurag, It's a little unclear whether you mean _gnuradio_ or _gnu in general_. I'm not a part of gnuradio, but I'm trying out answering your question because I find it hard to understand and I worry busy people could ignore it.
I quickly searched the gnuradio website to find answers. The contact information for gnuradio is at https://www.gnuradio.org/categories/contribute/ . There are chats on Matrix at #gnuradio:gnuradio.org and on IRC in #gnuradio on libera.chat . There's a lot of information at https://wiki.gnuradio.org/index.php/Development . The following issues are listed as good first issues for contribution: https://github.com/gnuradio/gnuradio/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22 K >
