I used the 1.8 for the entire WPX SSB contest, with a DSP width of 2.1 KHz. It sounded great. I never messed with any of the settings for the entire contest. To get this combination of DSP=2.1 and crystal=1.8, one has to install the 1.8 filter as if it were a 2.1, so it switches in at DSP=2.1. This installation setup is most easily done using the K3 Utility. In practice, normalize, then use high cut until the filter switches in. To me, the audio sounds best using that technique. WPX SSB is traditionally the worst-case QRM-fest, and the 1.8 filter was just the ticket for dealing with it.
