Ah yes... I have become used to viewing them as one system.
Thank you for the link to the USRP mailing list, I will explore the issue
with them.

I'm new to Pastebin, and I couldn't find an option to upload images, so I used
ImageShack instead.

I'm not convinced by the way you handle the complex part of the FFT result ...
You can't just drop it, it's needed for the reconstruction ...

Huh ?
To make sure I actually ran a quick python test before posting :

Hello GR Forum,
I have to add some instructions for test purpose into some files of
/uhd/host/examples
Could you show me how to make the new files, or send me the link of How to
instructions.
BTW, I never used CMake before. If there is another tool for the purpose I
am ok too.

I am curious as to the purpose of the 0x55 that is used for padding digital
packets to the USRP (in addition to sticking one on the end of the packet
to begin with)? Are these ignored and dropped by the USRP, or do they
serve some other purpose? And if they are ignored and dropped by the USRP

not installed correctly.
Please note: The version of GNU Radio you are using is old. In fact, it's
ancient. Even if you get it to run without error, it makes a lot less fun to
work with that than with GNU
The repository is here. I tried compiling but it is not ported to GR 3.7 yet.
Hopefully it will be updated.
