Voice QAM Mod/Demod

Hi everyone,

I´m trying to send and receive real-time voice with USRP E110 and GNU
Radio as software, I’ve already seen some tutorials and think I’m
following instructions correctly, but I still receive intermittent
syllables of the original sentence.

Sincerely I don’t know in which part i’m mistaken, it´s that a
processing overload consequence? Do i have to change something in the
GNU Radio Companion config files? Is the flow graph wrong?

Look forward to hear from you at your earliest convenience.



I´ve attached the flow graph, I hope that helps.
