[Elecraft] What crystal filter do you use the most?

[Mike Reublin NF4L]

The filters you guys are discussing are roofing filters. The filtering you're thinking about is done digitally, and is continuously variable. The K3s  isn't your Dad's analog rig.  

Here's an Elecraft article explaining roofing filters. http://www.elecraft.com/K3/Roofing_Filters.htm

The main reason is it works well for both CW and RTTY and of course the DSP does all the rest. I also ordered a 2.1 khz filter so if I go past 400 hz I get that one. It works well for me but this is just my opinion.
