Re: Gnuradio 3.8 on a Raspberry pi 4 B?

To add another piece of information to this discussion, last night I built the whole GNU Radio 3.9-maint on my Raspberry Pi, and it wasn't too bad.

I followed the instructions from here:
- https://wiki.gnuradio.org/index.php/InstallingGRFromSource_on_Raspberry_Pi
- https://wiki.gnuradio.org/index.php/InstallingGR#For_GNU_Radio_3.9_and_Master_Branch
- https://github.com/gnuradio/volk#building-on-raspberry-pi-and-other-arm-boards-32-bit

The heavy step, which was the 'make' in the GNU Radio 'build' directory, took about 2 hours and 10 minutes on the Raspberry Pi using 'make -j 3' - I think it is a reasonable time considering I built all of the in-tree modules except for gr-uhd.

You really should get one, if only to monitor ADSB from airplanes on your own.  


Oh my.  Many of us have always had Marcus on the "Marcus pedestal", thinking he knew or more importantly experimented with all things tech + Linux.
Maybe we need to create a crowdfund for him?

Why?  I think the RPi is the most influential STEM tool ever created. RPi + DSP = new converts and experts

Years ago, Fred Martin (Media Lab) designed the coolest SBC called the miniboard for undergrads for the MIT 6.170 course; he shared the board layout with me and while at Ohio State a small group of us made thousands of them. Fred was the first Ebon in my book.

At the same time I was working on the TAPR DSP59 project and was holding both the mini board and my recently hand assembled DSP59 in my hands thinking there _had_to_a_way.   There wasn’t. 
A lot has changed.


I think the world of computing is becoming more level. By this I mean that in core middle range of mainstream computing, they are all getting closer from a performance standpoint, only differing by factors of ten or so.

Think about what the performance of the RPi 12 will be- it will be limited, but likely perfectly capable of doing some magical work for us.
These fringe (and fun) SBCs and projects help produce the needed experts that we need.

Apologies for evangelizing a bit on the gnuradio list-please keep up the great work.
