Re: [Discuss-gnuradio] Questions on US digital cable ...

Vijay, I would highly appreciate it if you can capture a few QAM-64 snapshots. I was able to successfully demodulate signals captured from a QAM modulator, but I don't have access to a real-world cable source. I guess the python script "usrp_rx_cfile.py" (in the examples directory) can be used to

Hello, Has anyone done this integration before? My first question is both Click and GnuRadio are in C++ so it would not be hard (in theory) to do so. But I haven't seen an example of calling GnuRadio APIs in C++. All of them so far are in Python. Is this true? - David Li
