It does not appear to happen if I run in the debugger. I've tried many
times but never go it to happen in the debugger.

sometimes there is a core file and sometimes there isn't.

Hey,
I'm having a problem building my application. If anyone can tell me what
I'm doing wrong it
would be appreciated.
All of the files I'm talking about are in gr-qtgui/lib
There is a public routine, set_yaxis, in FrequencyDisplayPlot that I
want to call. A pointer to that class is
used in spec

Basically, you have two down conversion chains that share a common RF
frontend, but
A little confused.
I am using the gnuradio-companion to configure the uhd.usrp_resource.
What is the difference between the rf_freq and the center_freq? How the
tune_request (is it a UHD method?) can be reflected in the
gnuradio-companion setting?

Hi,
What I want to do is try to use the two antennas of SBX simultaneously.
The TX/RX is used for duplex communications and the RX2 is for sensing. The
two antennas are working different frequencies.
But this solution seems to be unfeasible, as someone said the receiver
chain of SBX is the same.
Hi everyone,
I just wanted to point out a new feature of GNU Radio. Thanks to Ben
Reynwar, we have a new Python manual. You can find the current version
for GNU Radio here:

Like the Doxygen manual, this page will be updated with every

Hi!
I have some questions regarding the implementation of Packet Sinks
with GNU Radio in general.
Since GNU Radio 3.6 there are some new blocks available like the
Packet Encoder and the Packet Decoder. Also the Simple Framer Block. I
haven't had success in utilizing them. I wonder whether there i

Hi everyone!
I've been using log power FFT block for signal power estimation. I've fed
the output of Log Power block to my custom block in which I search for peak
in power spectrum and then I sum up bins left and right from that peak
until the turn is reached. C++ code for power estimation:

Sir
I am trying to build an SID SDR receiver,,where i require a file sink...
When i run my flow graph,,i get a file of format octet-stream being written
into my computer.
But i am not able to access or open my dat octet-stream file.
Sir may i know how can i access the data being written into it?
