Raoul,
It's not just the filter that matters, its the filter skirt response
too. I have 2 x 400Hz INRADS in my MkV (one in each IF) and another
in the sub rx. IMO the INRAD 400's are a better option than the
Yaesu 250's because of their tighter skirts.
Agree if you do not have nearby close-in signals the roofing filter
is not really worth the cost.
