I wish I had acted on the problem sooner, but I recently was ticketed with my Valentine by a cop using a Decatur Scout (Assuming that is a k-band gun). Not a single blip of detection. I had been noticing recently that most speed signs were not coming up on my detector, even when they detected my speed accurately. It was concerning, but in NY state, almost all cops use Ka, so it was put on the back burner.
I thought that maybe it was because I fiddled with the settings to mute K-band under a certain signal strength. However, I went to a speed sign after completely restoring all settings to default, and it still didn't go off. The frustrating/confusing part is that I still get k-band falses from drug stores, other cars, etc.
Ka band and Laser seem to be working perfectly, so this problem seems strange to me. I believe the software version is 3.825 or around there. Does this seem to be a hardware issue, or something that could be solved by updating the software? Thanks in advance.
