Hi Simon,
I recommend using QT GUIs. WX GUI will be removed eventually.
'stream to streams' does not duplicate samples. In your case the first
sample goes to output 0 and the second sample goes to output 1.
<repeat pattern>
For AWGN you should observe another noise for in your FFT plot.
Your received signal is not a perfect AWGN signal. e.g. your dip is
probably some 1/f noise caused by some analog part in your USRP. Have
a look at the unprocessed samples form the USRP source.
happy hacking
Johannes
