[Elecraft] K3: SSB - WPX - Filters - Controls

[Matt Zilmer]

FWIW, I run two SSB filters - 2.7 and 1.8 KHz.  I find the 2.7 is fine
for ragchewing and light (no crowds) DXing and contesting.  I can also
vouch for the 1.8 KHz roofing filter.  It *kills* sidesplatter, esp.
when used judiciously with the DSP to clean up the passband edges.  I
plan to substitute the 2.8 8-pole for the 2.7 one of these days, but
it's not a priority.

Eventually, you get used to pulling down the Hi Cut to rub out high
freq chatter.  The 1.8 and DSP together are a very powerful
combination.

Also, FWIW - the human brain is The Ultimate Filter.  NR can only help
compensate for its front-end input.  That being said, the K3's NR is
the best I've heard in my limited 37-year ham experience.
