Joel, I think that this is one of those situations that if you need (want) it, you know you need (want) it. As you point out, a useful way to determine the most effective roofing filters for your K3 is to see where you keep the DSP set most of the time. Like Don, W3FPR, writes, I happen to find ~700 Hz to be a good bandwidth for scanning the band (or a pileup). I had been operating my K3 at 700 Hz DSP BW protected by the 2.7-kHz roofing filter before I even knew about the special filter! I was planning to get the 1-kHz to help reduce AGC pumping from signals farther away, but got the narrower one because I never went above 700 Hz. I also have the 400-Hz, which is really super for running on a busy contest band.
I'm obviously very happy with my 700-Hz filter. (No connection, just a satisfied customer.) 73, --Ethan, K8GU/3.
