[Elecraft] KX3 roofing filter query

[Chris Meagher]

Hi,  I have installed the optional roofing filter into my KX3 #4559.

The manual advises that bandwidth switches to 3000Hz when Weaver
demodulation is in use on SSB. However when I reduce the RX passband to
2.4KHz, which is when Weaver is supposed to kick in, it stays on FL1, until
I reach 1.7KHz. At this point, FL2 is activated, however this is so narrow
that it is close to unintelligible.

Is this normal, or am I missing something?  Maybe using width/shift rather
than Hi-lo cut doesn't activate Weaver? I would much appreciate some
enlightenment as to how it all works, as I'm mainly interested in close in
rejection, without having to discern which side the intrusion is coming
from. Also I find anything below about 2KHz bandwidth too difficult to
discern.
