Hi Henk, the problem is that the RTL dongle (and any SDR peripheral) just gives you the signal as it is in the air -- you will still have to demodulate it to get audio! Now, wild assumption: you want to listen to FM Radio for a start. So: * configure your audio sink to 44100 Hz sample rate * use

Hi Simon, > Is it possible, that the way my music_cf function is outputting the data, might cause some trouble? 181 floats isn't really a "round" itemsize, and since GNU Radio can only build buffers that are multiple of 4KB (==4096B), I assume that you get a large buffer (probably 4096 items of

Hi Patrick - So what's happening is that with GRC, because it was installed via MacPorts the MP version of Python is used. The terminal only knows what you tell it via environment variables such as PYTHONPATH (already suggested by Kevin Hofschröer) and PATH. In your case right now, I'll bet that
