[Elecraft] Advice on Additional Roofing Filters for K3

[Tom Bowles]

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?
