I've had two Omni VI Plus radios. In each case I had a 1.8 KHz and a 500Hz
in the N-1 and N-2 slots with the 1.8KHz, 500 Hz, and 250 Hz filters in the
6.3 MHz IF slots. Never wanted for anything else. Also, never had a
concern for S meter accuracy with these filters.
As I recall there are some jumper settings for gain adjustment to compensate
for the filter loss as associated with the N-1 and N-2 positions.
