This should probably be continued on the usrp-users mailing list.
You haven't said what daugtercard you're using.

of attenuation inline?

Hi all,
I am working with an s-band radio and am receiving
its OQPSK-modulated signal on an USRP N210. The
signal I'm seeing on an FFT and constellation plot
before any processing are not as expected though.
It is very different from the example shown in the
GNU Radio tutorial 7 (random source to a
constellation modulator to a channel model). I
also looked at the signal on a spectrum analyzer
and it did not show the repeated peaks I am seeing
on my FFT. Does anyone know where I might be going
wrong or what's happening?
