[Elecraft] K3 with 1000 Hz filter

[Rajiv Dewan, N2RD]

I am using the 1Khz filter.

It is my most used filter for CW, my primary mode of operation on HF.   
My whole filter complement is 2.8KHz, 1Khz, 400Hz and 250Hz.  So for  
all width settings between 1Khz and 400Hz, I use this filter.

Regarding efficacy, I only recently got the 1KHz filter.  Before  
getting this filter, I would be using the 2.8Khz filter when I set the  
width to 500Hz.  There was a larger difference in noise level between  
400 and 500Hz, more that just the change in bandwidth would indicate.   
I attributed this to having a wide roofing filter.  Now that is much  
less the case.  This is purely subjective, with no electrical  
measurements.  YMMV.
