I can create a TNF but it has no effect whatsoever on the noise I'm trying to block.  I haven't a clue as to why this feature suddenly stopped working.

Did you click the TNF button at the bottom of the SmartSDR window to enable TNF globally?

I'm sure you have globally toggled on TNF left below. Next step would be to reset your 6300, first saving your profiles.

As others have already have said, if your Tracking Notch Filters on the screen are showing in Grey, you need to click on the "TNF" icon in the lower left corner of your SmartSDR screen.  Your filters will then highlight in green (as shown) and will be functioning.
