[Discuss-gnuradio] spectrum analyzer

[Abram Young]

Hi,

I'm a recent gnuradio/python user (newbie) and have played with the python 
pieces and USRP as far as time will allow for now.  I can write my own 
program to record A/D streams to disk, but that's about it.  I'm using 
Octave to read in and plot the streams then.

I'd like to either modify the usrp_fft.py code, or add the fft_sink call 
to my own .py (preferred) and output to stdout.  Specifically, I need to 
access the data from fft_sink to find the maximum, and output it's 
frequency/value.  How do I do this?

FWIW, I'm using the gnuradio as a cheap spectrum analyzer.  If I can send 
ascii to stdout, I can make some RF measurements.

Any help with the gnuradio python interface would be appreciated.  I've 
looked through the docs online, but the I/O with fft_sink isn't obvious to 
me. (a non-programmer who writes ugly c-code when absolutely necessary)

Thanks,
