I use 2.7 and matching DSP setting for almost all casual use. I don't use the narrow SSB filter (1.8) except for contests and occasional encroachment. In that case NOT being able to remove loud sidebands from above and below is far more fatiguing. And I find myself jockeying shift all during the contest based on conditions. The narrow filter also keeps up or down loud sidebands from hitting the analog-digital converter stage in the IF, and needing to engage the (necessarily) primitive analog hardware protection AGC.
The narrow sounds great during the contest and when the contest is over I can't stand it. : >) 73, Guy.
