I got probably the crappiest C/O range ever last night. I was driving down the interstate with nothing but another car about 200 yards in front of me when my V1 alerted to K band and started to ramp up very quickly. About 5 seconds later it was going full blast as I passed a PSP cruiser parked parallel to the road in some kind of cutout in the terrain. Everything happened too fast for me to notice but I'm pretty sure he was using the external window mounted units they have because of the smooth, linear ramp up and the fact that every time they're parked line that, that's what they're using. I'd estimate I got about 500 feet of warning, which absolutely terrible compared to the 1.5 to 2 miles I usually get from those things.
Maybe the terrain was blocking the signal from being able to shoot straight down the road but it wasn't enough to block it from an angle so he could still get speed readings (and I could get 5 seconds of warning).
The sad thing about this encounter is that I could have known about it for literally 10 minutes before I got there. I don't have a smartphone for Trapster but I set up the route I take every night so it would send me text alerts when live police are reported. Right as I was going down the ramp to get on the highway I thought I felt my phone vibrate, but since entering the highway is sort of a high workload time I ignored it and forgot about it. Later on I looked at my phone and I realized that what I ignored was a text alert for the exact same trap...
I didn't get anything on the CB. I don't usually on this route. It's garbage for a few minutes until I get away from some truck stops and then nothing because there's not enough traffic.
