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.

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. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
