Ka Happy Dance
Ok, I probably shouldn't bug you guys with a post about this. At least not till it happens a few times over. Obvously, I took the precaution to slow down to PSL, and lock in cruise control, whilst trying to figure what was going on.
So, anyway, I'm driving to work about 9:30 am-ish, and traffic is light on the 6 lane road. I get a Ka band alert, bogey counts 1. After a moment I check the arrows, and they say from behind. Alert ramps up, still behind. Then beside then behind, and once in a while ahead, but mostly behind, and this funky valentine dance goes on for 2 or 3 miles like this. A few times the signal drops out, then it comes back. During this time, a few cars go by me, but I can't see an RD in any of them.
The arrows and the fluctuating signal strength are not changing in any meaningful pattern related to any of this traffic, so I never was able to locate the source of the signal.
My hope is that there was a true, strong, Ka radar, and that the arrows were responding to the signal bouncing off other objects (cars ahead, concrete divider on the median, etc).
My worry, of course, is that the v1 had a heat stroke, though I've been careful to take it down when parked, and keep the fan or a/c blowing on it while driving in the sunshine.
It may have been a little confusing for the arrows when there were so many cars around.
Yeah, I wonder if radar signals will refract/reflect off other cars. That might account for one bogey seeming to come from differing directions.
I had my V1 pick up radar while the LEO was out of visual site. It happened on both Ka and K. Chances are you had a LEO far behind you, possibly an unmarked and he was running I.O.
