Hey, you can use also our repo if you use the Raspbian that has everything pre-built. Tested and working well on RPi4 with Buster on many SatNOGS stations. https://software.opensuse.org/download/package?package=gnuradio&project=home%3Alibrespace%3Asatnogs-unstable On 3/7/20 6:45 PM, Marcus M

is there a set_output_multiple() in pyhton blocks?

Hi all, I was writing an embedded python (general) block in 3.8 and wanted to use set_output_multiple as I have done in C++ in the past. It seems that this method does not exist. I just wanted to verify this. Is there a way to set the output multiple in a general block in python? thanks Achilleas

Sv: Accessing top_block from an embedded python block?

Hi Derek, thanks a lot for your reply. That kinda makes sense to me, but im not sure about the tutorial, it doesn't seem to be very explanatory. You say that i can pass the buttons ID to the python block, but i cant seem to figure out how i would do that, as variables don't have outputs that i c

Re: Real-time video streaming

I'd really recommend using uhd_packet_tx_tun or any other of the current examples over tunnel.py, which we mourningly¹ retired² a while³ ago. Tunnel.py was meant as a demo of how to make GNU Radio work with network interfaces, and as a proof of concept that you can make GNU Radio your real-world p

Re: How GNURadio3.8.1 on RasperryPi4 ?

Dear rrrBbert, the instructions are in fact for GNU Radio 3.8, so not for a previous version. Anyway, I'd not recommend building GNU Radio from source, at all, when there's binary packages available. That's just way harder, and has no advantages. Especially, at high cost, avoid building on an em

Dear radio friends, Can anyone guide me (a rookie on HelloWorld level) how to install GNU Radio Campanion 3.8.1 on Rasperry Pi4? If I follow the (currently) most recent RPi NOOBS 3.3.1 the installation guides fail (e.g. https://wiki.gnuradio.org/index.php/InstallingGRFromSource_on_Raspberry_Pi)

Real-time video streaming

Hi, Thanks for the help. I am trying to stream a real time video taken from a camera. I know that I will use gstreamer to take and encode the video. And then pass it to the gnuradio and do some digital processing operations on it. And lastly by using a usrp, I will transmit it in radio frequency ra
