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

[Don Wilhelm]

Tony,

To reduce the width on SSB, try just using Hi Cut instead of the width 
and shift controls.  Normally when reducing the SSB filter width, the 
low end should be near 300 Hz (the K3 uses 250 by default). Keeping the 
low frequency corner of the SSB filter fixed at 350 to 300 Hz preserves 
intelligibility as the highs are reduced with the Hi Cut control - try 
it, you might like it better than fussing with the Width and Shift 
controls - I do it that way all the time, no need to adjust the low end 
unless the filter is VERY narrow (less than 1400 Hz = Hi Cut at 1650 Hz)
