Stan,
I am not going to give you a terse answer, but I can say that the
sensitivity of the KX3 does not depend on the roofing filter.
However, the roofing filter will give you more rejection of unwanted
signals that you may encounter in crowded band conditions.
If you do not operate when the bands get crowded, you will not notice
the difference with or without the roofing filter option.
If you do choose the roofing filter, be certain you do the calibration
if it is a kit. If you order the factory built KX3 with the roofing
filter option, that calibration will have been done at the factory.

I am going to order another KX3 this week. Probably tomorrow. The last
one I ordered in 2012 did not have the roofing filter option and I do
not THINK I missed it.
I use ONLY CW and I do NOT contest. I like to CASUALLY chase DX and I
play in low stress sprints like NAQCC but mostly I just like to RAG CHEW.
