My Escort 8500 X50 seems to have week KA band detection.
Today, I got a KA alert about 5 seconds before an approaching police car came. When in direct visual site, I got only about 4 KA bars on the signal strength indicator.
Is there something wrong with my detector or is it the way the police cars are setup in my area? Generally speaking, the KA readings I get are always very weak. In contrast, I can pickup K from quite a distance.
Is my detector working properly? How can I tell? It did once say "Self Cal," but a reboot seemed to fix that.
Does anyone here have the equipment to properly test a detector like this?
