Dear All, I'm new to Gnu Radio. I looked carefully to the doc and tutorials but could not find any simple answer to my problem. I have a radio signal from which I'm able to visualize the FFT in GNU Radio Companion. Now I would like to save the FFT (more exactly the magnitude squared, or the spectrum) accumulated over a given period of time (the average over time) into a file.
I found the following blocks in GRC that seem to be helpful: - stream to vector - FFT - complex to mag - file sink However I did not manage to save any accumulated spectrum... Any help (eg a woking example) would be very welcome! Thanks in advance. Adellain
