Thanks for the follow-up, this is similar to a 1 second noise burst every 60
seconds or so we had on our ham repeater. The reason could be identified
after months of search by coincidence. The repeater sysop visited his
fathers office, monitored the input frequency of the repeater like he had
done
Hi,
after opening and generating the hier blocks still the top_level.grc has
missing blocks, at least LTE estimator outputs and unpack MIB inputs are
unconnected, leaving a large white area in between. How should this flowgraph
look like, is there a screenshot available somewhere?
Just wanted
Well done!

Hi Tom,
I have removed tb.wait(). Now the sequence is
tb=top_block(options,0.8)
tb.start()
sleep(3)
tb.stop()
I want my program to stop here and take new values which is not happening
right now. It executes till sleep(3) and then hangs somewhere.
You have asked to stop the flowgraph internally,
hello every buddy
as we know in any plot lik water flow or fft sink there is
positive and negative values are present . if we want to present only ssb
i.e. positive or negative value .
how it can be done
help me if any one done the same ...

Hi all,
I meet a problem with gr-modtool. I created a new out of tree mode.
Compile and install work fine but when I want to create the GRC module
via gr-modtool makexml, give me the following error.
No GNU Radio module found in the given directory. Quitting.
PS, I am quite sure I am in the
Hi
I used a blank work() function as follows
def work(self,ins,outs):
print " i m in work "
self.mark_done()
using "mark_done(), I got the control back in the main loop.
When I use my specific work() function with mark_done() after a successful
event, I get following error message:

Hi Ralph,
unfortunately there are no screenshots yet. I guess it is a good idea to
add some. After the estimator, there should be 2 blocks: Decode PBCH and
Decode PCFICH. They take the same stream. and work in parallel. Then after
Decode PBCH there is supposed to be a 'Decode BCH' block. These blo
Hi everybody,
some time ago I stumbled over the problem that I missed a Qt version of
some blocks. In particular I wanted to have a Qt numbersink and a Compass.
Thus, I created them [1] with Qt designer and integrated them into a GR
block. For now, they use Python. There are '.ui' files that have

One of the PCs acts as network controller, it creates data the other PCs
should transceive. The network controller there

Hi Tom,
You are right increasing the number of taps by 100 is not the case, after I
debugged the results a bit more.
The problem seems to be in the number of samples consumed as you mentioned
above.
The full definition for the filter I am using is
firdes.root_raised_cosine(nfilts, 1.0, 1.0/nf
Tom,
Is there going to be a fix soon or should I go with the 3.6.5 version of
gnuradio?
Thanks,

Hi everybody,
I added screenshots for all the hierarchical flowgraphs and the top
flowgraph to the docs directory. I hope this helps to build the whole
LTE flowgraph in GRC.
Although, I realized that would be very helpful if the hierarchical
flowgraphs would be compiled with grcc during make and t
Hi Ralph,
I had the same problem at first myself, there is no need to reconnect
anything in the top_level.grc block so long as all the hier blocks have
actually been compiled.
In my case the biggest problem was the LTE_estimator_hier block would not
compile because the 'import lte' failed (see ear
Hi Johannes,
With regard to my earlier message regarding the crash I'm seeing, I note
that a few tests fail when I run make test, is that to be expected?
Also do you think it would be possible to publish the reference waveform
that you are using ?
That way I could check to see if the crash occurs
