v1.4.16 won't load

very briefly you loaded a v1.4.14. I loaded that and everything worked fine. For the first time I actually had a working NR feature.

I loaded v1.4.16 and while it loads fine, during the radio update I get the error message "This SmartSDR version is incompatible with the selected radio's model"

I have a brand new out of the box 6500. Hardware version 1.3.55. Reverts to sw 1.4.3.132 where the NR does not work at all.
