Hi everyone,
I am using a USRP with only a DBSRX daughterboard installed. The
image at the following link is a screen capture I took.

Does anyone know why the spike at 921.6 MHz is there? I have
observed many of these spikes in other parts of the spectrum using
usrp_fft.py. I looked for them using a real spectrum analyzer connected
to an antenna and did not observe them.
I used the same parameters in usrp_fft.py that were used in the
first image at the following link.

This spike does not exist in their plot.
I appreciate your responses.
Thanks,
Thomas
