Probably not without knowing exactly what was accidentally deleted.
What process do you use to install gnuradio that is so difficult to start
over with? What OS?
On Ubuntu 14.04 using pybombs, it takes me about 35 minutes to completely
wipe gnuradio from my machine to having it fully installed ag
I somehow attached the wrong correlation screenshot in my previous post.
Here is the correct one.

Andy and all,
Sorry for the delay in reply, I've been working hard to figure things out
on my end.
I use the polyphase clock recovery block for timing recovery.
I have essentially copied the test_corr_est.grc example that was included
with the block in the examples directory. It seems that this
Dear all,
I followed a tutorial online to install a sdr software and accidentaly
deleted files from my gnuradio installation. It took me a very long time to
manage to set up everyting so before I start from the beginning I wanted to
ask you if it is possible to undo my mistake. I am on Ubuntu 14.0
Which USRP is this?

Hi all,
I'm playing around with timed commands on the USRP, but I'm not sure I
understand them correctly.
I've got a usrp connected as "u" and set to center freq 700e6.
>>> u.set_command_time(u.get_time_now() + uhd.time_spec(2));
>>> u.set_center_freq(800e6); u.clear_command_time();

the callback is on the .xml file from the grc folder, the parameters are
changing but the waveform is not updating.
on the other hand, all my custom blocks i get "AttributeError:
'top_block_sptr' object has no attribute 'top_layout'".
it was working all along but I just got that recently, I searc
the point is that if the print is not appearing, then the callback isn't
working as you expect. You should really make sure to use the right
variable names.
You're not really sharing all the interesting information; it's a bit
hard to figure this out in what's becoming a dialogue.
I'd like to ask y
Ok, this boils down to one thing:
The flow graph you're doing doesn't really have logically "separate" RX
and TX parts.
Just put it all in one big GRC file and you should be set; do you
encounter any problems when doing that?

So you mean this one:
http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsWritePythonApplications#Multiple-flow-graphs
That refers to the Push-to-talk example from gr-uhd, which is a bit
older, I think.
However, the whole point is that you can simply write your TX flow graph
and your RX f

Hi Sylvain and Tom,
Thanks a lot. It works.
So the "Taps" should contain all the matched filter coefficients for
Filter_Size (32) filters instead of just one filter. Then each filter takes
SPS (4) out of them to generate a phase-shifted shaping filter. Hence, we
have a filterbank with different p

Which one of the dozens of examples?

Hi Themba,
the interesting point here is where you register your callback. You say
you've included the callback in the .grc file; if that's the case, you
should find it searching for the name of the variable you change using a
slider etc in the python file GRC generates.

Thank you Marcus for the reply.
let me show you an example of what I did. but so far i am not getting any
output from it

The WX GUI Waterfall Sink works as always.

Hi Themba,
in principle, what you describe sounds right; can you insert some 'print
"set_foobar called"'' in the set methods of your hier block, to check
whether they are actually being called?
