I also had about two S units loss on an Omni VI+ when switching in the 9 MHz 
IF
500 Hz crystal filter.  The problem was traced to a bad crystal in the 
filter where
re-soldering would not fix the problem.  So the filter was modified to be a 
7 pole
instead of an 8 pole filter.  It works fine now and the filter loss 
amplifier in the
9 MHz filter board exactly compensates for the filter loss when the 500 Hz 
filter
is switched in.
