To the USRP experts out there:
I reclocked my USRP from 64 to 65.536 MHz and have recently discovered
that the I & Q samples are no longer orthogonal, rather they seem to be
only 70 degrees or so apart. I would guess this is due to some hard
coded values in the CIC or HB filters? Is there a USRP command to
correct for this phase imbalance? Thanks!
