Hey everyone, I was able to solve this problem now: my installed version of GNU Radio (3.10.5) simply didn’t contain the Fosphor blocks. After removing this version and installing GR 3.10.7 from source the blocks are now available in GRC. (See release notes for GR 3.10.6, “gr-uhd” https://www.gnuradio.org/news/2023-07-19-gnuradio-v3.10.7.0-release/)
So far I’m struggling with getting Fosphor to start, Error “[!] CL Error (-1001, …): Unable to fetch platform IDs”. I wasn’t able to find any up-to-date help about this online. How did you install Fosphor / OpenGL? I’m using a AMD CPU and since AMD stopped supporting OpenGL I had to switch over to POCL.

However, the RFNoC Fosphor display block bogs down the GUI so much that it's practically unusable. I haven't been able to look into what's wrong, or whether I'm doing something wrong though. -- Clint On September 4, 2023 12:51:10 PM UTC, "Bachmaier, Luca" <luca.bachma...@iis.fraunhofer.de<mailto:luca.bachma...@iis.fraunhofer.de>> wrote: Hi Johannes, thank you for your reply. Where can I find this module? The gr-ettus module (https://github.com/EttusResearch/gr-ettus) is apparently not required for 3.10, on the site it says "Use gr-uhd directly". That aside I'm installing GNU Radio 3.10.7 right now which should contain the RFNoC Fosphor blocks (as opposed to my current version 3.10.5).

In GNU Radio companion, I noticed that there are no blocks “RFNoC Fosphor Block” and “RFNoC Qt Fosphor Display” available (See this workshop https://www.youtube.com/watch?v=M9ntwQie9vs <https://www.youtube.com/watch?v=M9ntwQie9vs> @ 22:13 for a flowgraph that uses them). My basic software setup is: -OS: Debian 12 -GNU Radio 3.10.5.1 -UHD 4.3.0.0+ds1-5 I was wondering why these blocks aren’t available or if I need to install an additional module in order to get them. The module gr-fosphor (https://projects.osmocom.org/projects/sdr/wiki/Fosphor <https://projects.osmocom.org/projects/sdr/wiki/Fosphor>) just installs the “standard” version of Fosphor, **not** the FPGA / RFNoC implementation. Thank you and regards Luca
