Re: [Discuss-gnuradio] Fwd: Creating a FFT plot like the one in this youtube variable

Thank you all so much. I am able to get the single peak with the sin wave. I go through the readings when time allows, thank you for the suggestions. In the mean time, I am curious to know if GRC is able to produce a FFT for a wide band. For example, can it produce one for the FM radio channels, sh

[Discuss-gnuradio] Creating a FFT plot like the one in this youtube variable

Hello, the issue I am having is I cannot display a graph that shows a wide range of frequencies and their power. When I attempt it with the QT GUI Frequency in GRC, I get something similar to the one in this video (FFT plot ) but then I transmit a signal in the

I have been trying to make my NI-B200 scan frequencies that I have in a text file for a couple days now.

I have been running usrp_spectrum_sense.py for hours now and I cannot figure out where it is getting its power_db from. I narrowed it down to m.data. My end goal is to have the program scan frequencies from a desired list that I have created and output its power. usrp_spectrum_sense.py scans frequ

I'm trying to send my recordings from a USRP Source(hardware: NI B200) to a database I set up. I have been searching the internet for hours and I have come up with nothing. There was one post that mentioned it, but only the fact that there is a way to have MySQL and GRC working together. Is there a

I am having trouble reading a file and putting it as a variable or some way so that the USRP Source block will read it and evaluate each item. I'm using a file source and i tried connecting to a message sink, but I'm stuck there because the output of the sink does not match the input of the USRP So
