Patience. I don't believe it is ready yet, but there is a
very strong hint below. In my opinion this was one of the most
significant announcements at Dayton and it should have a very
strong impact on sales of newer radios, at least for those of us
interested in actual receiver performance.

Darned right -- if it is as good as advertised, I'll be one of the first in
the queue. George W2VJN has spent at least 2 years looking for the right
filter to do this job at 70 MHz -- I talked with him last year about it,
and he was sorta pessimistic. Well done, Inrad!
