The throttle block has some peculiar limitations. For example, if you try to
set the throttle very low (like < 1k) you'll find that there is minimum
threshold and what will happen is it will still give you way more samples than
you expect. Before I found the head block, which allows you to
Hi Vicfield,
I actually work on the ground system that receives these signals. They are
distress signals from different beacons: EPIRBs (boats), ELTs (planes),
PLBs (hikers or anyone who wants a handheld device) that are captured or
relayed through satellites to the ground. This allows rescue
Hi everyone! I'm working on expanding the OpenCL modules for GNURadio
and I want to test them with some FPGA's that support OpenCL. There's
a few from Xilinx and Altera it looks like, but the ones I've seen are
a bit pricey.
Does anyone know of an OpenCL-capable FPGA card for under $1,000 for

Hi Fernando,
You are assuming that the signal you are getting at the receiver is not
delayed with respect to the one being sent. You are thus using a cosine
signal source with no phase correction. This is not true, since you are
using filters, which always delay samples (moreover, you should make
I am trying to do an install of gnuradio into a directory on my

was working until it hung for a while. After looking at it a bit, I

Hello, Victor:
Thanks for your information,
I exactly tried to decode the file with the real EPIRB signal from a PLB,
although I’m pretty suspicious about that is beyond me too much…
But it is really surprised me that what you said:
The signal "trigs" detecting is too complicated to implement
I'm not familiar with that exact flowgraph, but nothing will "break down"
in a CPU only flowgraph. Drag the ctrl port perf monitor block on to the
flowgraph and look for the avg throughput counter for a block you care
about. It'll give you items/sec. PS - the throttle block only gives you an
Hi Fred,
this is a warning that you want to execute a 'No GUI' flowgraph without
a terminal.
GRC tries to run your flowgraph by opening a new terminal. All prints
etc. will go into this terminal. But GRC is missing the path to your
terminal application.
How to fix this:
Go to ~/.gnuradio
Dear all,
I wondered what would be the maximum sample rate that my PC can handle for
a basic psk mod-demod. I have used the “prbs_test.grc” from gr-mapper as it
contains all the necessary blocks. I changed the sample rate for the
throttle to 32k, 320k,10M, 100M even 10G but the system did not
Hello.
Yes, with Time sink I can see the difference, but if the signal is
compound of some other signals (for instance signal=1K/amplitude +1
+2K/amplitude -1 +3K/qamplitude +1 +4K/amplitude +1 ) i would like to
see the 2k signal as -1 amplitude, but in the power spectrum it will
appear as
Hi.
Is there a way of visualizing ampitude spectrum (with + and - signals)
instead of power spectrum?
