Well at the behest of HappyA$$ I took one third and final go at the K band construction sign. This time comparing rx65 and 9500i.
I won't go into huge detail, you all know the routine. In this case:
9500i = 1.2 miles
rx65 = .9 miles
Approaching radar sign from behind (radar shooting in direction of travel).
rx65 = .3 miles
9500i = .2 miles
didn't do a rear radar detection test today.
Image is a bit hard to see @ this size but Red track is rx65 Blue is V1 and yellow pin is location of sign
