Marcus,
OK; dumb question. How do I apply that, other an editing the source
manually? I tried the following, but it didn't like it:
cd /usr/local/src/gnuradio/
patch < 0001-qtgui-fixed-non-changing-from-sec-to-ms.patch
Thanks,
Lou

Hi Mike
Alex (the gqrx and Gpredict author) suggested using pyephem to me once when I
asked about this. I did have a little play with it, but haven't done anything
interesting or useful.

Hi Sreena,
this is a bit hard to debug like this.
I smell network problems, possibly firewall-related. Use a network
sniffer like wireshark to figure that one out :)

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.
For e
the plot should be the power of the signal against the frequency, when u say
the format, do u mean the type of the variable ?

Do you want to plot the data using GNU Radio? What's the format?

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)

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 th

satellite tracking into a Gnuradio block. One you could simply use in a
