[Elecraft] Roofing Filter Usage

[George A. Thornton]

Go back to filter settings and set the bandwidth of the 1.8 filter a bit
wider, say 2.1.  Then use the hi/lo adjustments during operation.
Typically I keep the low full and gradually lower the hi settings.  When
you get the filter narrow enough the K3 will automatically switch from
the 2.7 to the 1.8 filter.  Several experienced users recommended this
to me and it works well.

I purchased a K3 with the standard 2.7 Khz SSB filter plus the 1.8 Khz
SSB filter.  I did not purchase a cw filter because I operate very
little cw.  But that may change.  The 2.7 is in slot #1 and the 1.8 is
in slot #2.  I know that if I push the FILT button that I can switch
filters.  But I was experimenting around listening to a weak station
that was rather close to a real strong station and when I activated the
1.8 Khz filter I was still getting some carryover from the strong
station on the weak station. Are there other controls that I need to use
that would enable me to knock out the real strong station so that I
could clearly hear the weak station?  I'm sure there is help in the
manual but I certainly can't find it.  Any help would be much
appreciated. Oh and by the way, I love the radio.  It's like a breath of
fresh air compared to my Kenwood TS0480s.  Mark KB3Z
