[Elecraft] [K3] KFL3A-1.0K 1 kHz, 8-pole roofing filter : Purpose?

[Ron D'Eau Claire]

I've been pounding brass for over half a century and I very seldom use a
receiver bandwidth less than 1 kHz - often wider. 

I prefer my "gray matter" filter 99% of the time.

Ever since I started looking at the K3, I've been wondering about the
purpose of the 1 kHz roofing filter.

It's too narrow for SSB, and, for me at least, WAY too wide for CW.

What would it be used for?  RTTY?

I have the 2.8, 400 and 200 filters in my K3 as of now.  I'm considering
adding the 1.8, but will probably wait until I get some experience with the
2.8 and DSP.

Thanks,
