[Discuss-gnuradio] DC component

Hi all,I'm observing a DC component inside my spectrum as you can see
in the two pictures in attachment (differentfrequency ranges), this DC
is only shown when there is no active transmission (only noise).
Consider I'm already using the UHD's advanced tuning specifying the LO
at 3Mhz. I'm receiving a signal witha central frequency of 430MHz with
a bandwidth of around 5Mhz, the DC due the LO should be quite away.
Is this normal ?

Regards
Gaetano
