Hi everyone,
I am running a simple flowgraph where signal source block generates sine
wave and time sink shows waveform. Sample rate is 100 Msps and carrier
frequency is 1 MHz.
But phase of signal deviates periodically, you can see from link given
below.

Is the
loosing samples isn't important for my application, my sample rate is 4
Msps but my CPU is weak(Intel N3150I). so I only want to disable these
annoying messages.

I'm using Gnuradio with Ettus B200 device. My application runs fine but
UHD driver prints O... messages randomly. I guess some overflow
or something else happens inside UHD driver,but I want to ignore these
long UHD messages. How can I disable O messages.
regards.

.4 per
day. When i use cheap RTL sdr with osmocom driver, i haven't any leak
problem but this B200 sdr with uhd driver induce this kind of memory leak.
Has anybody had a similar memory leak problem? I attached my test program.
this basic program only transports uhd samples to null sink.

Hi everyone,
I'm playing with gr-ieee802-11 wifi_loopback example, I want to change
some variable values in every cycle, but i cannot find any way to do
this. Is it possible with gnuradio-companion?

hi all,
I have usrp and tvrx daughterboard,but tvrx sensitivity
is very bad, minimum input signal level is 40 dBuV(equal to-68dBm).
and noise figure is 8-10 dB. even if you have hi gain antenna, weak
signals die in TVRX. then I decided to purchase LNA next to antenna.
LNA that I chose is minicircu

hi all,
I want to record for example a fir filter output
to file when I want. I have develop basic application,
given some parts below

def start_record_samples (self):
self.stop()
self.utfil = gr.file_sink(gr.sizeof_float,"capture.cfile")

hi,
I have captured some records that are float from file_sink,
I want to import these files into scipy but I cannot find any
function to manage to import.There are some .m files for matlab.
Is there a solution for scipy?
sincerely.

I'm using pydev which is python plugin for eclipse,
hi all,
I have two signal which is float and I want to use
atan2 fuction like this,
self.arctan = math.atan2(x_hyd_filter, y_hyd_filter)
but gnuradio gives error given below,
...
self.arctan = math.atan2(x_hyd_filter, y_hyd_filter)
TypeError: a float is required.
In your opinion what is the pr
according to eric's "gr.flow_graph and friends are gone" message,
legacy applications using gr.flow_graph is no longer supported.
but I wanna use
gnuradiogui(http://funwithelectronics.com/sdr/gnuradiogui.py) which is
based "gr.flow_graph". Then I converted it to "stdgui2.std_top_block"
interface. b

Hi,
I have downloaded rfx400 pcb from
http://gnuradio.org/svn/usrp-hw/trunk/rfx/pcb/
,but gEda pcb gives "illegal fileformat" error. I'm aware that usrp pcb is
not available yet.
but ettus says that "all of daughterboard schematics and layout can be found
in the usrp-hw repository" in their web
