Hi Dave,
I have the first version of the OHR SCAF filter. It's excellent.
It was designed by Sam Ulbing N4UAU in FLA. His article was in QST a few
years ago, not sure about the issue. Mike Tracy at the ARRL could tell you
if you ask him via e-mail, mtracy@arrl.org.
Very shart cutoffs. I use it in all my contesting and occasional
ragchewing.
You can also get the template kit from the ARRL if you'd like to build your
own.
