I know this is going back a bit but I would like to do the same thing for my
Gnuradio satellite ground station. I was actually tempted to compile
satellite tracking into a Gnuradio block. One you could simply use in a
flowchart without any of the messing about with XMLRPC but like my new

Please help me find the rational reason!
Because calling produce means, I'm done, go ahead and take those sample.
Don't call it until you are reall done ...
GR is a multi-threaded applications, each work() function is executed
in different threads and as soon as you call produce(), other
I found one modified example from usrp_spectrum_sense.py which mentioned the
power and noise calculation, could u plz help me figure out how it works?
for i_bin in range(bin_start, bin_stop):
center_freq = m.center_freq
freq = bin_freq(i_bin, center_freq)
Forgot to CC: the list:

I assume m.data is a list of FFT magnitude-squared data; it can't be complex
otherwise math.log10() won't work. It must be magnitude-squared since it is
using 10*math.log10(), otherwise it needs to be 20*math.log10().
It finds the minimum out of all the bins and calls that the noise floor.

OK; dumb question. How do I apply that, other an editing the source
manually? I tried the following, but it didn't like it:
