The police left a transportable radar speed display on the road next to my home and I got to test my Bel RX65 today. The radar speed display(K band) was on the bottom of a slight hill pointing towards the top. I had my Bel RX65 set for highway and tried mounting both the bottom and the top of the windshield.
When I drove from the behind the display, I got nothing from my Bel RX65 until I passed the display. I got 3 bars then it died down at the top of the hill.
When I drove towards the display from the southbound road, I got 1 bar like 0.5 sec before the display came to my view then I got full bars. I looked at Google Earth and my estimate is that Bel RX65 detected the K band radar speed display at about 300 yards.
If it had been a real cop, I would have been ticketed for sure.
Is this normal for RX65 or is mine defective? I bought it about a year ago for road trips but haven't used it much. I live in VA so I don't use it much. I've used it for some trips to Georgia and New York but it never caught a cop yet! I've seen plenty of cops hiding and motorists pulled over but it didn't beep a thing while I got false alarms when passing big stores(I would get 1 bar when I'm right next to big stores like Walmart then it disappears). I'm unsatisfied with my radar detector so far.
