Glen, if you are interested in using SDRplay API version 3.X (I think the latest version of their API is 3.07), and you are on GNU Radio 3.7, you may want to take a look at the gr-sdrplay GNU Radio OOT module I modified to work with SDRplay API version 3.X:

Hi community! I'm Isaac. I'd like to ask you a question. I'd like to add in my thesis information about the first time the USRP blocks appeared and were used. I found that the USRP1 was designed in 2004 but I'm not sure if this USRP appeared with the blocks or not.

To whom it may concern: Just a tip: If you are building GNU Radio from the source, dependencies and build procedures for Raspberry Pi is available at the GNU Radio Wiki. It assumes that you are doing on-board compile. See: https://wiki.gnuradio.org/index.php/InstallingGR#From_Source Regards,

There's no special configuration. Just install dependencies and build from source. Put root on SSD or it will be very slow. Ubuntu 65bit is fine. In general GNURadio is hell to build and get dependencies right, but in the end it works well. --Albin On Thu, Dec 17, 2020, 16:37 Kristoff wrote: >

Hi all, before we finish this year, we do want to announce one more change in how we accept contributions into the GNU Radio code base. One thing that we take very seriously is the whole business of license compliance. GNU Radio is GPLv3-licensed, and that's not going to change. But also, we

I suspect a lot of the graphics could run perfectly fine if they took advantage of the gpu better. A lot of the current rendering in GNURadio (and GQRX) is very cpu bound. I had a spectrum and waterfall running easily at 60fps on a pi3 by using opengl properly. Using vulkan on pi4 the sky is the

Can't stress this enough. Running a 32 bit Linux on a RPi 4 would be like running Windows 98 on a modern PC and expecting top performance from the CPU. You're not making use of the CPU you have, you're only making use of a legacy mode that it still supports. Best regards, Marcus On 17.12.20

HI all, I also have a RPi4 (*). Some follow-up question. What OS would be the best for this? Would running 64 bit make a difference? I don't know to what degree this is related, but I did a test running WebGL (**) on that pi, and I got about 1/3 of the frames per second on my RPi4 compared
