[Discuss-gnuradio] spectrum analyzer

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)
