Be prepared to spend about $200. Small price to pay for an Omni VI+ +.
You get to choose either the SSB or CW roofing filter. The CW filter is
600hz wide. With the programing switches, you can make it kick in when
hitting either N-1, N-2 or either.
It matters not if you have any filters in the option slots on the 9mhz
board.
This thing installs at the very beginning of the 9mhz IF chain, just like
the Orion. After this filter, the signal hits the OEM 15khz wide filter,
which has an easy job now, then through the first IF amplifier, which is
now happy not to have so many sigs to amplify, an on to your optional 9mhz
filters.

Here is the completed installation of the INRAD roofing filter. It mounts
on
the final amp box toward the rear, bottom of the rig. Take a look.
Oh, It works too. I noticed no loss of gain or increase of noise. With it
engaged, the 250hz filters become slightly more effective. I have nothing
to
measure BDR or IMD. The next contest will tell the story.
