Hi Almohanad ,
thanks for this information, can you provide more detail or is there any doc?

I don't believe there's a document for this it's more of an exercise left
for the motivated user.

Hi Josh,
Thanks for your quick reply! We are actually using rx_samples_to_file as a
first attempt at benchmarking the systems data transfer speed. We give a
proper crtl+c whenever we terminate the program, but the problem persists.
We tried rx_timed_samples per your recommendation and found that
I've noticed that when stopping a GRC sketch and starting another, I get
unknown stream ID reports from my B100, requiring a restart of the USRP to
recover. This used to happen a while back, but was fixed. Perhaps the fix has
been broken or the issue is similar.

There is a mictor connector (J301 on both USRP2 and N2x0) that has 32 signal

Problem solved! rx_samples_to_file doesn't include a stream_cmd_stop!
Here's our fix:
Add the following after line 93 (outfile.close()):
if(!num_requested_samples){
uhd::stream_cmd_t
stream_cmd_stop(uhd::stream_cmd_t::STREAM_MODE_STOP_CONTINUOUS);
usrp->issue_stream_cmd(stream_cmd_stop);
}

Hello All,
A couple of days ago i had installed a GNURadio digital image
processing block that makes an image source and sink block available as
displayed in the image below.

Hi all,
I'm working on an experiment which needs to modify qam modulation block in
gnuradio. But I cannot find the source C++ file the qam blocks use. e.g.,
OFDM demod block uses digital_ofdm_frame_sink in
gnuradiobuild/gnuradio/gr-digital/lib. What about qam blocks?
Thank you for your help!
