Does anyone have any ideas that explain this 13 dB

What gain do you have set for the receive side? For the BasicRX or
LFRX, this is really the gain of the input driver to the ADC, which
can vary from 0 to 20 db, and effectively changes the full

Good point - I forgot to mention that I set the gain to 0 via the
--gain=0 switch passed to usrp_fft.py. So I shouldn't be seeing any
clipping.
Also, another detail that I forgot to mention - I didn't consider the
carrier at the center
