Hello,
I try to test the flow graph that I have created with gnuradio-companion 3.9
but when I run my script I have this error "module gnuradio.uhd has no
attribute rfnoc_tx_radio.
I work with UHD 4.0, gnuradio 3.8 .
Someone have solutions for this error please ?
Best regards
Sadly, it's really the issue as shown by your output that your linker can't
find the itpp
library. Since you've said you've installed it, please check whether it's
installed where
your toolchain expects it. *how* you've installed it, specifically, might be
helpful. Was
it also using macports?

Hi,
To properly explain the issue I'm facing, I recorded a video showing
Oscilloscope waveforms.

The gnuradio flowgraph is here:

Your message is confusing. Do you mean that your created the graph under
gnuradio-3.9 but are trying to execute it under Gnuradio 3.8?

Hi Mike,
Again, thanks for the great help and sorry to bother you again.
The Polyphase Clock Sync seems to have serious problems. It works well at 2
sps, but does not work for 4 or 8 sps. I replaced it with the
recommended Symbol
Sync block, which appears to work at the different sps based on

The flowgraph I provided (Fri, 12 Mar 2021 19:00:33 +0100) works
with 4 sps (delay=58) and 8 sps (delay = 102)

I went through my bash history on that machine and I realized that I
accidentally installed from the `ppa:gnuradio/gnuradio-master` PPA and
not the `ppa:gnuradio/gnuradio-releases` PPA. Maybe this is where things
diverge between us.

Does anyone have any information on the use of the subject block?
There is no documentation on the GNU Radio site and a Google search revealed
nothing.
Thanks,

It is delay(x) + fir_filter(conj(x)). The delay is probably to match that
of the FIR filter. There isn't any further info about usage in the code
base.

I’ve Installed itpp via MacPorts too.
Actually I've solved this library problem by adding ITPP_LIBRARIES to
target_link_libraries in lib/CMakeLists.
However, I got another issue.
Although ofdm_parse_payload block (from the OOT module) is well recognized in
gnuradio (in GUI app. as shown in the
Hello,
you may google for ROCKY sdr. It uses a frequency selective IQ
correction to remove images (automatically).
It is needed because of the fact that IQ imbalance is frequency
dependend too.
There are scientific papers available, but currently i have no link,
