[Elecraft] K3: 2.1 vs 1.8

[S Sacco]

One aspect that Doug leaves out, however is that of audio quality.

Signals will sound different with different filtering.

Using a 2.8 XFIL and DSP to make it 1.8 KHz, I found SSB signals to be
a bit "tinny" and hard sounding.

I installed a 1.8 KHz XFIL, and found the audio quality to be
improved.  It was quite noticeable as I turned the width control
downwards to where the 1.8 XFIL kicked in - the audio experience
sounded like a continuation of what I was hearing at 1.9, only
(obviously) an itty bitty bit narrower.  The tinniness and harshness
was not present.

All IMHO.
