Awesome project! I hope it doesn't get taken down by DTS!

Here's my question: Was there a reason for not using the GNU Radio framework for this project?

Thanks!

That decision was made by the original author (Andrew Wesie), but I think it makes sense because nrsc5 only needs a tiny fraction of the functionality that GNU Radio provides. Implementing the functionality directly in nrsc5 avoids the need for a large and complex dependency.

One downside is that we don't get the broad hardware support that GNU Radio provides, but maybe we'll someday take another crack at integrating SoapySDR. (See https://github.com/theori-io/nrsc5/pull/131 for an earlier experiment with that.)
