Hello Vishwanatha,
the filters in GNU Radio are all written in C++, and the mathematical
core functionality is implemented in several versions for different
machines in C with a mixture of SIMD intrinsics (read:
close-to-assembler instructions), because filtering is often a very

Hi all,
I want autostart=off in the options block so I can start a flowgraphs GUI
environement, allow the users to configure settings and then start the
flowgraph signal processing. For example, let the user choose whether the
receiver should decode BPSK or QPSK at runtime.
My question is, how

Thanks for the reply. I'm fairly sure I was using the same repo init command

Just a followup to my own note. I did
ldd /usr/lib/libgnuradio-qtgui-3.7.6.1.so.0.0.0
and no library comes up as missing.
Thanks,

I've recently received a request to have GNU Radio flowgraphs recover
gracefully in the event of power glitches, or transient Ethernet anomalies
that are severe enough to break the dataflow. ie. the event should be
noted, but there should be a way to re-init the USRP for continued
operation with

Hi Marcus,
I'm using GNURadio 3.7.5.1. Under [Graphical Sinks], I have Baudline Sink
, Fast AutoCorrelation Sink and also Eye diagram. It doesn't work!
I didn't get your hint of creating an eye diagram :(
Best,

I worked around a problem like this by installing an in-line power relay in
my remote nodes. Not ideal, but in some rare situations, even forcing the
FPGA to reload was not successful. Sometimes a power cycle was the only
hope.
That said, I've heard some lovely things about reset commands
Dan,
I think you were working a different, USB-related issues.
My task is a bit different. The goal is not to power cycle the USRPs - its
to re-initialize and resume after and power cycle, without intervention
from an external executive or operator. (ie. by some task that monitors

Hey Mike,
If you suspect that you have problems with libraries, maybe you want to run
the install script with the prereqs option to install all the dependencies.
wget http://www.sbrac.org/files/build-gnuradio chmod a+x
./build-gnuradio ./build-gnuradio prereqs
