[Discuss-gnuradio] 8 MHz Spur on USRP?

[Clark Pope-TWC]

I have a USRP with RX and TVRX daughterboards. With spectral displays on
both I get a large spur that's 2.25 Mhz from the 5.75 MHz that the DDC is
programmed to. So I conclude that its actually 8 Mhz probably a subharmonic
of the 64 MHz ADC clock. Do other USRP users see the same spur? Or do I just
not have something grounded well?

Thanks,
Clark
