So, actually, your code already has the freq recov block? If so, I really
have no idea on how to solve your problem.

Hi Alex,
I have read the generic_mod_demod.py and find the fll block you mentioned is
in freq_recov block, which is before the time_recov block. However, the file
sink I use to collect data is after time_recov block. So I think in this case,
it's already been through carrier frequency correctio
Hmm,
I don't think so:
What I apply to board A ADC0 shows up on scope0, and what I apply to board A
ADC1 shows up on scope1, so there are definitely two different ADCs involved.
Looking at the scope traces they are connected as set by the line
self.uhd_usrp_source_0.set_subdev_spec("A:A A:B", 0
FLL = Frequency lock looping.
The corresponding C++ block is digital_fll_band_edge_cc.
and you can find the usage example in generic_mod_demod.py in
/gnuradio/gr-digtial/python.
There are some discussions within this community before, just search it for
how to use it properly.

I don't think the RRC filter is used for carrier frequency correction. In
gnuradio, the FLL filter can be used for CFO correction.
Please correct me if I am wrong.

On gentoo we have ebuilds for all of this... just so you know. We are
always happy when you report bugs though :-)

I worked on an "interleaved char to complex" block some time ago. It was not
working right until I changed it to specify 'signed' char instead of letting
the compiler default happen (which could be either way). - Tim

hello, i want to write a simple energy detector without using c++, only
existence blocks and the numpy lib
So far, i have the following graph
usrp_source -> head -> stream_to_vector
could i read the values from stream_to_vector and write them to a
numpy-vector? is it possible?
Hi,
I am having problems with the gain-settings on the RX-channels of usrp1
My USRP1 is populated with 2 LFRX and 2 LFTX.

I'm pretty sure this doesn't happen if you start with a clean build dir.
If you run cmake with -DCMAKE_INSTALL_PREFIX, all paths will be correct.
Only if you re-run cmake with a new -DCMAKE_INSTALL_PREFIX, it will only
update the install path, not the config path. If you're doing that, you

Hi all!
To keep two different versions of gnuradio I used two different
install-prefixes.
/usr/local/gnuradio-3.6 and
/usr/local/gnuradio-3.7
The idea was to switch between the two versions by setting a symbolic link
/usr/local/gnuradio to the directory just required.

Hi all.
Today I tried a fresh install of new master from the actual git repository.
Everything compile well but make test gave the following errors:

146:qa_ofdm_txrx
161:qa_qtgui
===
1:
/home/schroer/gnuradiocomponents/gnuradio/build-3.7/volk/
the problem was the lack of ldconfig in the end of the installation
I used:
sudo ldconfig
after the installation of extras, and it solved the problem
