I have that mod in an OMNI VI + and really like it.  I have the 2800 in both 
slots
The receive is so much nicer and I have actually had the stations in the 
other part of the world pause a pile up " to find out what radio Paul is 
using".  A real rush when that happens.
I did not make the Inrad notch filter change but just park the notch at the 
high end.  The audio was too hissy for me anyway.

The ONLY down side is that the bfo adjustments become super critical and the 
best sideband suppression obtainable will be about -38db.  That reality is 
mentioned in INRAD literature.

Also, I may be over zealous with my praise as the stock TT filters in my 
radio when I got it used were really "broken"

Has anyone used a 2800Hz filter in their Omni/Paragon rig in the 9mHz slot 
to widen their band width?

Just wondering if it was worth the effort, and did it improve transmit 
fidelity to the receive stations?
