Re: 1.8 kHz SSB Filter

I definitely agree regarding having a 1.8 kHz filter for SSB is a
positive attribute. In fact both of my radios have 1.8 kHz filters.
And by reducing the DSP BW to 1.8 kHz and shifting the PBT, one would be
amazed at how well a SSB signal really sounds. Certainly worth the
investment in my experience.

Agree
And just want to tell you that I am using Filter width=1500 and Filter=750.

Maybe I missed it, but there once was a link on the Elecraft website with filter recommendations.

Get the 1.8 if you work ssb. Experiment with shifting the pass band
for maximum clarity. Youll be amazed just how narrow it can get and
still be understandable.

I plan on a 250 Hz CW filter, but am going back and forth between the

a really difficult to understand voice signal, while the 2.1 allows

For example, the 1.8 could be set to turn on at 2.1 to take advantage
of skirt shape.

I primarily DX, and operate in some contests as well. I know SSB
contests really need a narrow SSB filter.

Any suggestions on the matter from those who have gone this route before?
