Hi,
It seems that you may need a Power Squelch filter, which can be found in
Level Controllers category in GNR Radio Companion.

If our squelch blocks don't suffice, and you *do* need to implement your
own, you'd use a general gr::block.

A couple of pointers:
- This is a bit like radar, where you want to time rx and tx in sync
very tightly. Check out the gr-radar toolbox as an example how to do this.
- You can evaluate and write tags to control the transmission time of
bursts. Check out the gr-uhd manual for tag names.

Thank you for your replies!! I really appreciate them.
If you want to give a look about my porting,here is possible to see

There will be a number of GNU Radio developers at the Wireless@VT
Symposium[1] next week. We are having a small reception at my house,
near the Inn at VT. We'll start gathering after 6PM on Tuesday, the
evening before the event starts.
We'll have some beer and food (likely pizza).

Hello everyone,
I come to you with a rather strange request :)
I’m looking into the possibility of installing OOTs that were precompiled in
one system onto another.
Lets consider basic stuff first:
1. Versions of all software are identical in both systems (linux, gnuradio,
uhd, build suite,
Hi Martin,
Sorry for the delay in response. We have been able to put some time into
debugging this issue and here is what we've found:
1) We have confirmed that the input stream to the HPD block is correctly
tagged when the block freezes. The tags we set as "trigger tag" in the
block are on the i
Leonardo,
Have you tried copying the entire module directory (including build) from
one computer to another? What errors do you see when you do that?

Hi Richard,
You mean copying the whole module directory and doing a “make install” in the
remote computer?
I havent tried that, but I guess that would end up the same way, since all I’m
doing is copying the target directory (where "make install" puts things) from
one computer to another. This
Hi everyone,
I am testing the BER performance of the gmsk of GNURaido with two USRP, one
as a transmitter, and another as a receiver.
I find that the error bits would cause the subsequent bits getting error.
The received bits are compared with the transmitted bits, and if one bit is
received corre

Hi guys,
anyone have ideas how to implement next scenario:
I need to RX signal on freq 150 Mhz +200 khz but need to jam all signal around
this freq,
means from 145 Mhz to 150 Mhz and from 150.2 Mhz to 155 Mhz should be gaussian
noise there.
Any ideas ?
Would it possible with 1xUSRP or 2xUSR
This is interesting, and kinda serious. Also, we've had reports that
tags go missing in the past, but it's something that's hard to verify.
How did you confirm the input stream is correctly tagged? If
get_tags_in_range isn't finding tags that it should, that is most likely
the issue you're seeing
Yes I will file a bug.
We put a tag_debug block right before the HPD input. The tag debug stdout
statements continue, while the get_tags_in_range function of the HPD block
returns none.
We will continue debugging this to see if we can learn something more concrete.
The time it takes the flow
Hi, I am sorry for the delayed response.
I checked the centering of the OFDM signal and it looks pretty good. Even
looking at the signal's spectrum using SDR# on other computer was very nice
- book-grade example of nicely shaped OFDM spectrum. Today I upgraded from

Hi Leonardo,
the most elegant way of this is
* making/having a pyBOMBS recipe for that OOT
* configuring pyBOMBS to build into a prefix
* build the OOTs using that
* and usings pyBOMBS' "package" command to create a .tar.gz out of that
* unpack the package where you want to use it
This *really* n
