My posting under this subject heading was not at all
a complaint; rather it was meant to be some musings
about a possible problem identified by others--  one
that Elecraft is currently addressing.

Certainly this is the case; however Elecraft has provided 
a wonderfully effective NB in the K3-- thanks in large part
to the use of narrow roofing filters.  It is at least possible
that those who reported some difficulty with the pileups
during the recent ARRL CW DX contest were employing
their noise blankers at the time.  I thought it worth
mentioning as part of identifying and solving a problem.
