Re: Help check flow-graph

[Marcus Müller]

Hi Akinyele,

GNU Radio companion has an "screen capture" function that allows you to
directly save **good** images of your flow graph. Also, your operating
system has the same. So, I'll respectfully point out that taking photos
with a camera is a complicated and not overly useful method to
communicate flow graphs. Can't read anything in these.

So, checking your flow graph as far as possible:

* uses legacy GNU Radio 3.7.11, which is an old release, even for that
legacy release series. Update to 3.8 as soon as possible. Not a good
idea to start a new project based on old software. I think this looks
like Ubuntu, so a simple update to Ubuntu 20.04 LTS solves that
* WX GUI: don't use that. Use Qt instead.
* Can't tell you whether your channel sounder is correctly configured
without knowing your channel *and* the required precision of your
channel state estimate.

As Marcus D. Leech already explained in May, you might want to make sure
your DSP/channel understanding is good enough and ask a more precise
question!

Best regards,
Marcus M.
