INRAD includes a note with this filter only, that says "you may need to 
adjust the carrier balance for optimum performance upon installation".

I found that with my Corsair, I was indeed experiencing a bit of carrier in 
my transmit audio after installation.  Making the adjustment is very easy to 
do if you own an oscilloscope.  You put the scope probe on the output 
connector (74) of the DSB board.  You tweak T1 (output xfmr) for maximum 
signal (rcv mode).  Hit the PTT switch to go into xmit mode and adjust R1 
and R2 for minimum signal.

For Corsair II, the reference designators may have changed.  Procedure for 
Omni V/VI may be completely different.

73,
