Flaw in the 1.8khz roofing filter

Robert Wood
K6LL mentions the negative comment (performance) of the 1.8khz filter
documented in the QST review.   Has this been resolved?
Any update?

(If you read the QST review and the note on the 1.8 filter - nobody would
buy one, the 2.8 yes - it out performed the 1.8....)

and does it matter if I buy it from Inrad or Elecraft - wouldn't it have
the problem either way?

This was the exact statement in the QST review,
"Elecraft reported that they are working on developing an improved
selection
process." I wouldn't read in that they are hand picking. If they are I
would
like a confirmation.

Is it better to buy filters from Elecraft, or is INRAD just
as good? I think I remember seeing hints in the past that
Elecraft was hand-picking some of the filters for low IMD
specs, especially the 1.8, which received some negative
comments in the most recent QST review.

I raised that question way back in January, purely in
response to the ARRL Review.

Since then I have bought two 1.8 KHz filters from Elecraft,
one for each of my K3's. Those filters perform very well in
contest service, with surprisingly good intelligibility.
Those are the filters I use all the time now on SSB.
