Thanks Walter. I had forgotten that Rob Sherwood had tested it. Interesting. The dynamic range looks pretty good compared with other rigs even without the KXFL3. I don't have enough technical background to understand the significance of footnote v, though. Perhaps some knowledgeable person could explain?

Would anyone who has a KX3 without a KXFL3 care to comment on their experience?

Yes, it is possible to quantify it. See the measurements with and without the roofing filter here (you'll need to check the footnotes):

Has anyone tried the KX3 both with and without the KXFL3?

The manual says it results in a "significant
performance improvement in rejecting extremely strong interfering signals that are just a few kHz away from
the received signal."

I wonder if it's possible to quantify that?
