[Elecraft] K3 filter presets I/II: present and future functionality

[K4IA at aol.com]

I don't like the presets floating every time I  make a change.  They are not 
presets, they are resets and I never know what  might result from pushing the 
button because I can't remember what width was  used the last time I switched 
it.

I would much rather have a wide preset  and a narrow preset that I can 
quickly and easily get to.  Even better if I  get to pick what that might be.  I 
would know that if I hit the preset I in  CW mode it will be a narrow 500hz and 
preset II will be a wide 1.5kHz.  In  SSB mode I might chose a preset I as 
narrow 1.6kHz with the passband slewed to  increase intelligibility and preset II 
as wide 2.1khz with the passband  centered.

The NORM function is nice but it is fixed too narrow (400hz) in  CW mode and 
too wide (2.8kHz) in SSB.  

Maybe NORM should be used  just to center the passband and then the user 
could set the two presets for the  desired widths and passband offset.
