The spectrum display for both my Orion II's is around 400 cycles low for
both LCW and UCW with both 3.028 and 3.029.

Also, the bandpass graphic on the display for the subreceiver doesn't
do the roofing filter indicator correctly for slot 3 in my case.
I have a 6Khz filter in slot 1, the 2.4Khz filter in slot 2, and a 600Hz
filter in slot3. The red roofing filter indicator bar for the 
subreceiver shows 6Khz for ALL bandwidths above 2.4Khz and the roofing 
filter indicator bar shows 2.4Khz for all bandwidths below 2.4Khz -- 
including those below 600Hz, so the 600Hz bandwidth is never indicated 
although for bandwidths below 600Hz, the 600Hz roofing filter seems to 
be working properly even though the indicator bar doesn't show it.
This has been the case with both 3.028 and 3.029 as well.
