[Elecraft] Filter and DSP

[Ron Midwin]

I have a K-3 with the 5 pole 2.7 KHz filter, and the 400 Hz 8 pole for cw.

I am considering getting either a 1.8 or 2.1 KHz additional filter for QRM.

My question is, the 1.8 would seem a better choice for rejecting QRM from a
station 2 KHz away, but what about how it sounds to listen to?

Has anyone done a comparison between 1.8 and 2.1 filters, plus playing with
the DSP?
