Hi Ellie,
I'm one of the authors of gr-sigmf. You are correct, we haven't had a
chance to port gr-sigmf to 3.8 yet, sorry about that.
As for reading sigmf files in 3.8, it depends what you need, if you just
need the data portion, you should be able to just use a normal file source
with the sigmf-d
Hi Marcus, all,
Well, seems you’re right that gr-sigmf hasn’t been converted to gr 3.8 yet.
Just finished installing gr 3.8, then attempted to run cmake to build gr-sigmf,
and that crashed with an error, saying it was looking for gr 3.7 but found gr
3.8 instead. I do need gr 3.8 for the other m
RE: the gr-qtgui question -- never mind. Just realized I forgot to install the
dependencies, that was silly
(https://wiki.gnuradio.org/index.php/UbuntuInstall). Will let you know if
gr-sigmf works once I get gnuradio 3.8 installed (given I don’t run into any
more snags). Thanks!

Hi Marcus,
Maybe that's the case -- I did notice some comments on the gr-sigmf github
page that seemed to indicate maybe it has been (at least partly) upgraded
for GNU Radio 3.8. But maybe not for 3.9 -- so I decided to try installing
GNU Radio 3.8 instead of 3.9 to test it out.
I followed the in

Hi All, does anyone have an example of how to control GOIO lines on the RPi4
from within a GRC flowgraph. I’m guessing it’s an OOT module.
I need to generate a signal of a few 100Hz & control GPIO lines at various
points though the cycle.
Alternatively, I could generate the signal & lines wit
Hello, most prolific SDR community to wander this wide globe,
TL;DR: brace yourself. If you're on master, we'll be breaking your OOT.
You don't have to worry about anything if you're using GNU Radio 3.8.
We're close to merging the pybind branch into master – and that means
we're improving thi
It may be the case that gr-sigmf hasn’t been converted to gr-3.8 yet.
The gr-sigmf folks are on this list as far as I know.

Hi Marcus,
Thanks so much for the advice, I really appreciate it! So when I tried
that, it did work, and I was able to run a flowgraph successfully in GNU
Radio 3.7, so that's good.
In the process of attempting to install some more packages (specifically
gr-ata), I found that I needed to upgrade

Hi Marcus,
Thank you so much, it's working like a charm now!

Ah, it's a Python heir block. You could reduce the quadrature rate further
so that the quadrature rate is closer to 200 kS/s and/or put a 200 kHz LPF
in front of the block. There's internal filtering for the various

If there's no filter inside "WBFM Receive PLL", place one before it. The
example in gr-uhd has a 400 kHz filter there.
