Well just today i was rolling down a 60mph highway and i got a few short random Ka alerts which i thought were falses due to the fact the traffic was light and no LEOs in sight.
A couple miles or so ahead i approached the city limits of a small town, the Ka alert was now pegging a 'nine', then stopped as soon as it started.
Ah ha, there he was, a LEO settin along side of the road running Ka IO!
Even kept getting intermittent Ka alerts short of a mile or so after i passed him!
Anyhow, i got this theory which i'll admit is not backed up with facts, that a lot if not most reported Ka falsies are indeed valid police radar.
If i would of turned off before i spotted the LEO, i would of sure chalked up those Ka alerts to falses. Just an observation!
