Greetings list,
I have hardly ever used gnuradio. But I want to use it for the usrp2_fft.py
to use as a sort of spectrum analyzer. I installed gnuradio with the script
created by Marcus Leech for ubuntu.
Upon running "usrp2_fft.py -f 2.45e9 -d 16 -g 20" I get a whole list of
errors at the bottom
I actually came across the FAQ that I should be running uhd_fft instead.
Don't know how I missed it before.
Thanks anyway.

Hello Dear,
I've monitored the automatic boot and I think that is the latest version
U-Boot 2011.06-00575-g6b73deb (Sep 07 2011 - 07:26:10)
I also checked uname -a
3.0.0.

Yeah I succeeded!
I installed libusrp from apt-get install tool (libusrp-dev).
The problem was that this library isn't configured for working with 52MHz
clock of my USRP1.
So I installed this library and then I replaced these files from /usr/lib
by other files that I compiled myself from an older
Thanks,
I think to try with the minicircuit ampli in the 5W version.

Hi all,
I am using a N200+WBX with samplerate = 5e6, no input signal.
Independently on the tuning frequency I have two strong spikes about 1
MHz far (see attached picture on 500 MHz tuning frequency).

I have a similar situation on 434 MHz ban
I developed a script for an UDH usrp_sink with GRC (in attachment).
Now, I would like to add it into my c++ application.
Someone has an example for that?
I don't find in the uhd c++ api how can I set input of my USRP with one or
multiple signal source.
Thanks

Hi Luca,
I've been running into a similar problem with random spikes. Are you just
running uhd_fft.py? Have you tried using benchmark_rx.py/benchmark_tx.py?

Hello to all users of gnuradio.
This is my first contribution to the gnuradio and consists of a change
in the GRC that takes advantage of 'max_noutput_items' to adjust the
maximum number of items allowed for any block in the GRC flowgraph.
The function that Do you seek to take advantage is in the
Hi Jason,
No, I am just using UHD driver.
The processing to perform FFT and so on has been developed by myself.
But I am quite sure that the processing is ok because with other
receivers works fine and
it provides correct results according to the test signals.
Moreover now seams that the span bet

Hey ,
I am trying to install gnuradio version 3.5.3 with uhd for digital

I've been playing with my simple_fm_rcv application, with both RTL-SDR
and UHD devices. I'd like to be able
to implement some kind of AFT. I tried using the PLL detector block,
but was unable to arrive at a set of
parameters that produced anything but near-rubbish coming out of it,
even getting
