Was driving home yesterday from NC. Driving south on 301 through a small town (Hawthorne, FL) when encountered a 34.7 GHz speed sign that was aimed south.
So I was picking up the backside of the the speed sign.
STi-r alert at 1235 feet, V1 at 710 feet.
STi-r (pop off, RDR off, segmented 2, 5, 8)
V1 3.872 (pop off, Ka Guard on)
I have a video that I used to determine the exact alerting distances. Can't seem to get the audio to play on the edited video. Approx 10pm, slight rain
