The local police department has older Ka band Stalkers in their cars. Not sure what model, but there is only one of them in their car (this is confirmed). I got three bogeys on Ka from it when I went by. There were no Cobras or other detectors around.
Could it have been a frequency hopping gun that the V1 saw different frequencies?
BTW: When I was on the Thruway the other day, I got four miles range on an SUV Trooper's rear facing gun in constant on mode (had someone pulled over). Another SUV was driving towards me and I got three miles on him.
