Grant et al;
I can agree that many hams do not understand the application of
"filters" in a radio, specially today with the advancements in DSP
technology. I find today that many many hams rely on "old school
methodology" to justify what they do. They, for the most part, seem to
shy away
Just an opine. Since these are ROOFING filters, and not the means of
determining the radio’s ultimate selectivity, you may not notice a substantial
performance improvement of the radio with 8-pole vs 6-pole filters.
I have my flame suit on, just in case — (it can be almost guaranteed to be

I think Elecraft altered their filter array recently ( maybe 1-2 years) and
maybe the order page hasn’t caught up. I believe they discontinued some and
added some 6-pole filters. I think that is what you have.

The "previous" web site used to implicitly say which filters were 5 pole and
which were 8 pole on the ordering page. The new "improved?" website omits
this information. Looking to answer the same question recently I had to
resort to looking elsewhere on the web!

Bill,
Thanks for your response. This filter, unlike the others, is exposed and there
are six crystal cans. Does this mean it’s a five-pole? I was sure I ordered
an eight-pole filter? When I do a search

Is your filter in a metal can. Eight pole filters used to be in a can. Five
pole filters were exposed parts. If the later, count the crystal cans. Should
be 5, 6, or 8.
