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.
