[TenTec] Inrad roofing filters for Omni VI, anyone using?

[Ben K8DIT]

Because the 2.4khz roofing filter is 25% of the stock12khz roofing filter in
bandwidth, one could surmise that there is an improvement of some
significance on cw over the 12khz stock roofing filter, though, not as much
as the 1khz.
Is this a correct deduction? Either way it would be interesting to find out
quantitatively what that difference might be.
The other question is whether one board could be used to switch between the
two roofing filters?
