[Elecraft] Re: K3 narrow filters

[wayne burdick]

Ron,

I haven't heard any ringing at all in our 200-Hz filter. It's quite a 
bit narrower than the 8-pole 250-Hz filter down to -40 dB or so, and 
it's the filter I used about half the time for CW and nearly all the 
time for narrow data modes. The 8-pole filter has steeper skirts, as 
you'd expect. But the DSP provides the ultimate attenuation anyway.
