[Elecraft] 8 pole vs 5 pole..I knew this would happen

[Darwin, Keith]

Oh, and no I don't think I did an apples to oranges comparison.  The
filters, whether placed early or late in the signal chain, have the same
effect on bandwidth and out-of-band signal rejection.  What I compared
was 8 vs. 6 pole and that showed me some things that are applicable to
the 5 vs. 8 pole choice we have with the K3.  While the filters were not
in the same place as they would be in a "roofing" application, the info
gathered was certainly applicable.

The notation below (previously posted) is referring to the final
passband filter and NOT a roofing filter.  You are trying to compare
apples and oranges.

===============================

I had 2 CW filters in my TenTec OmniV and did a lot of A/B comparing
with them.  One was an 8 pole Inrad 400 Hz filter and the other was a 6
pole TenTec 500 Hz filter.
