Dana, That is a good reason to use DATA A mode instead of SSB.

I have been using my KX3 with digital software and seem to have some odd behavior using the PBT. I have it set to do upper cutoff/lower cutoff on USB or LSB and am watching the received display on the waterfall. As expected, the upper cutoff in the noise follows the cutoff displayed on the screen, up to a point. However, if I lower the cutoff below 2.35 kHz, there is an additional dead zone (no noise on the display) from 1.4 kHz to 1.6 kHz. The same thing happens on LSU at 2.45 kHz. This appears no matter what band I am on, so I assume it is something in the DSP software.
