[Elecraft] Filters for K3

I use the settings I & II to go from normal and shift width for best signal
pullouts when working DX.  Please don't suggest this be changed?_(:

I'm with Don on this one.  In my TS-870, voice modes use Hi/Lo cut and CW
and data modes use Width/Shift by default.  I wish the K3 did the same.

Dave and all,

Your observation is exactly the reason I use HI and LO CUT for SSB.  
Typically one only needs to decrease HI CUT and the center frequency 
takes care of itself.  When the HI CUT gets so low that intelligibility 
is beginning to decay, a slight change upward in LO CUT can improve 
things, but normally LO CUT is a "set and forget" control for SSB - mine 
normally stays at 0.15, 0.20 or 0.25.
Try it and I would wager that most of you struggling with the WIDTH and 
SHIFT for SSB will never go back.

73,
Don W3FPR
