At the risk of being repetitive, I chose the 2.8 KHz and 400-Hz 8-pole filters for my main Rx and 2.8 for my sub-Rx. I run CW on VHF and up so "crowded band phenomena" is rarely encountered. On eme it is never seen. But I reasoned having the steeper skirts would be handy for HF-SSB and cascading the 400-Hz with the DSP at 100-Hz might net a slight improvement with super-weak CW on eme. I find the 400-Hz filter is narrow enough to make tuning for CW difficult enough (usually tune in 2.1-DSP and narrow down once on freq.). I added a 13-KHz filter for running VHF-FM on the main-Rx (works nice on BC am).
I bought the dual-bw filter for the KX3 figuring it might make difference in reception with the direct-conversion SDR. It appears to switch in at about 2.35 KHz. I can hear the change in band noise with it in. I have not spent enough "play" time to come up with optimum menu settings (most still the original). Today is semi-annual shack cleaning day (also wading into the "rats nest" of wires behind the console in preparation for hosting a "shack tour" at the end of our local hamfest in a couple weeks. Now that I have the KX3 and all my new transverters installed, I can accomplish a more "permanent" wiring hookup! (nothing in my shack is permanent!)
