Dan,
I can't comment on your particular flowgraph but I can tell you that you
will get a significant speed-up if you build volk and GNURadio from source
(and maybe fftw) as this enables all sorts off optimizations not in the ppa
for compatability reasons.
If you decide to go down this route I

I run a NBFM monitor 24x7 and it takes up a small fraction of a RPi3
(recording to files). It's likely that you are running across some sort of
rate/buffer problem, so keep trying!

Hello,
I do not try to run GNUradio over my Pi4 for the moment but I encountered the
problem you describe with the audio on a laptop.
I solved it by specifying the name of the audio hardware (aplay -l as far as I
remember in a terminal would help) and by checking the box for the blocking
Has anyone successfully run GNU Radio on a Pi 4? I recently purchased an
RTL-SDR dongle and thought it would be fun to experiment a little with
GNU Radio and learn something about SDR.
A couple of days ago, I fired up GNU Radio, and after having some
trouble figuring out how to get the audio
Got it !
I had to remove ~/.cache/grc_gnuradio/cache.json

Is the ofdm modulator and demodulator block removed from the gnu radio

Meanwhile I don't understand why I got this erroneous

It looks like the device is not properly initialized. Things to make sure:
- You're running UHD 3 on your host. Are you running UHD 3 on your device?
- It's not clear if there is a specific issue with get_num_xbars(), or if
there's a general RPC problem. Does uhd_usrp_probe work?

Hi
I facing a simple issue on my Ubuntu 20.04 gnuradio 3.8.2.0

I installed from ppa:gnuradio/gnuradio-releases on two different

Hi Volker
Did you succeeded in porting gr-osmosdr to GR3.9 ? Do you have some
repository for this ?
