[Discuss-gnuradio] Magnitude == RSSI?

2012-06-10 Thread Matthias Schäfer

Josh, The RPC-PMT block is definitely a great idea. Whether I go the python route or not, I will keep that tool in my back pocket. IMO, this solves the problem in a much more accessible manner than feval. Still, C++ may be better suited for this project. I'm going to be out of town so I'll hav
