Can you please suggest me the important steps & guideline for the
implemention frequency hopping using blocks in gnu radio.

*Ubuntu 16.04*
*GNURadio and gr-ieee-80211 installed yesterday using pybombs *
I get this warning when I run the wifi_rx.grc
"The total sum of rates (20.00 MSps on 1 channels) exceeds the maximum
capacity of the connection"
And then a lot of overflows.
I was generating 802.11g using a VSG.
How can we able to reset the gnu radio simulation during run time using
blocks.

Hi all,
I have a problem using audio sink on windows 10 using the installation of
the latest binaries from here:
http://www.gcndevelopment.com/gnuradio/index.htm
The audio is simply not playing what is SUPPOSED to play.
If anyone wants to give me some feedback on what may be wrong please
take a
Hey folks,
this is just a request for enlightenment. :-)
I was playing around with the dvb-s2 modulation blocks. I started with
the example graph dvs2_tx.grc and the example video (adv16apsk910.ts)
and an ursp. At the receiver side, I used an ericsson rx 8200.
I then increased the symbol rate an
Update: After a quick discuss with another dev, I am after that third dimension
view so the regular time or constellation sinks are not what I need. The time
sink has I and Q on the same Y axis, with time in X.
I was hoping there was an existing edit to the standard wx or qt time sink to
see I
Hi Everyone,
Does anyone know of a QT or Wx block that plots I vs Q vs time in all three
dimensions?

Hello,
I will try GQRX soon, we had it working on LimeSuite to where we could see
an FFT. We could not get get it to work on GNURadio.
I believe we have an error in our parameters for osmocom block.

Not really an answer, more of an alternate solution, but if you use gqrx,
(set driver string to "driver=lime,soapy=0") gqrx should provide a dropdown
to choose antennas from whatever magic was deduced by querying osmocom to
query soapy to query the limesuite driver, and return a list of antennas.
Hi Marcus,
What I do at the transmitter side is (QPSK signal):
pulse shaping(Root Cosine FIR Filter ) ---> resampling (where the
fractional resampler is inserted) --> low pass filter-->frequency shifter
(move the signal to the frequency it belongs to with respect to the usrp's
center frequency ) -

More than simply an Osmocom block you'll need a driver. The LimeSDR is
based on the STREAM (Cyclone IV) FPGA board + UNITE 7002 EVB, and the
Lime Suite driver was or
Hi Andy,
The fallacy I had in my own head was that the MMSE resampler also
filters sufficiently – I think that is not true; it's just a resampler,
you need to "select" (as in: filter everything else away) the
appropriate bandwidth yourself before.
Therefore: Yang, you'll need to filter befor
Hello,
I am trying to test our setup to see if there is any issues and I am not
getting any results for FFT and waterfall plot. I am using a LimeSDR connected
to a PC running the latest version of Debian. The LimeSDR is connected to an
antenna a coworker brought in which operates in the 162.550
Hello there
Is there any osmocom block made for lms7002 type evaluation boards?
