Hi --
This is both a query for information, and a bit of begging for help.
I want to put together a sound-card driven audio spectrum analyzer for a
very specific purpose (measuring the frequency delta between two closely
spaced RF carriers that have been brought down to audio via a receiver). I
would like to get resolution in the range of 0.01Hz over about a 100Hz
display window centered at 800Hz or so (the precise center frequency isn't
a big issue). I'd like a basic waterfall display and the ability to
measure the frequency delta between two points on the display. I need to
display the data in near real time for tuning purposes, though I don't need
the full resolution in real time -- as long as I can capture the data
stream for later analysis with the deep FFT, 1Hz resolution in near real
time is good enough. I don't need any other fancy features at all.
My question is first, would gnuradio be a good candidate to do this?
Second, as I've yet to actually *use* gnuradio for anything, would some
kind soul here be willing to help me with development? I need to have this
working by mid-November, and I'm starting from absolute ground zero in DSP
programming (and graphics programming, too).
Thanks to anyone brave enough to help me out :-)
