USRP2 Alias FPGA code

Has anyone else noticed that when using the u2_rev3_alias fpga code, the
spectrum is inverted?
The zeroing out of the coeffs in the hb_dec.v and small_hb_dev.v files,
causing either the I&Q samples to be swapped due to a misalignment, or
causing the conjugate to occur.
The standard fpga load shows the correct spectrum.
