[Elecraft] K3 5 pole vs 8 pole filters - attenuation in the passband

[lstavenhagen]

for what it may be worth, the 400hz 8 poles in my K3 and K3S are like brick
walls. I haven't yet found a situation where the 400hz filter plus using the
DSP to go narrower hasn't covered even the most crowded situations. 

I'm 99.9986% CW, so that filter is adequate for me but if you're a PSK
hound, for example, I could see the 250hz filter. For RTTY, I think the
250hz filter might be borderline, though...

Just my thoughts,
