I have a 200 in mine, and I never need it. Period. The 400 plus DSP is
all that I've ever needed for CW.

Hello all,
I recently acquired a K3 that came with the standard 2.7 kHz and a 500 Hz
roofing filters installed (no subrx). I mostly operate CW, SSB, and sometimes
RTTY contests, and I'd like to round out my filter set for better performance
in crowded bands.
I'm considering adding a 1.8 kHz for SSB and a 250 Hz for CW, but I've read
that the 250 Hz filter often measures wider in practice (around 330-350 Hz) and
may not be as sharp as expected. Has anyone experienced this, and would you
recommend it, or suggest alternatives like the 200 Hz or 400 Hz instead?
73,
