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.

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.

Right now I have the stock SSB and a 400 Hz filter in both main and sub
rcvrs. I would like to add some a few at a time. My first priority is to
add a couple to the main receiver, since it is the biggest chore to get
to.
I plan on a 250 Hz CW filter, but am going back and forth between the 2.1
and 1.8 kHz filters. I know that narrowing the DSP to 1.8 gives a really
difficult to understand voice signal, while the 2.1 allows in more adjacent
signals. However, the roofing filters may not behave in the same manner.
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?
