Beautiful job.  Very impressive.
It may be that using Raspbian not Ubuntu is my problem.
It would be interesting to know if other have success with Raspbian.

We’ve put our event detection on three Raspberry Pi 3B +

I have a 8 GB image .iso that I could put on line this weekend.
Where is appropriate for such large files?  We installed everything
on one Pi then just copied the image to the other SD cards.

This is setup for Ubuntu with Gnuradio for use with Airspys and
RTL-SDR dongles.

The Pi 3B+ can just about eat all 6 MHz of event samples without
loosing many samples.  The Pi can not FFT the samples to make spectra
without loosing a large fraction of the samples.

Probably the 3B+ could deal with 2.4 MHz of bandwidth, but not
much more.

The band pass spectra still look good, but a large fraction of the
samples are lost (at 6 MHz bandwidth, 12 MHz samples).

We have these in boxes near our telescopes.

Problem Solved! .....NOT!
Tell me, is anyone running GNURadio on a Raspberry Pi (3-B) using an
RTL-SDR dongle?
I thought I cured my problems then the next day, more problems.
This is what I thought fixed my problem (but later, didn't).

This kind of thing can be difficult to debug, but please refrain from cynical 
sarcasm here - especially if you want help and support.

If you're willing to share your progress and current issues, I'm sure there are 
people willing to provide some thoughts.


Is there not an Ubuntu image for the rPi?

I used a stock Ubuntu image for the Odroid C1 and just used the 
GnuRadio+friends from the repos, which included gr-osmosdr support for
   a number of different devices.

I did end up doing a source build later, but that was for device support for "newer
