I'm always envious when read tests results from USA. There are great distances of detection. Unfortunately my experiences are very different. Here (in Hungary) are low powered mobile photo radars only, installed on police or covert cars. I've decided to tests some detectors against european radars (Ku,K,Ka narrow bands).
There will be independent observer from Copcars, Hungary because I'm a distributor. I will post our results as soon as possible. I'm afraid that it takes a little bit long time because here isn't any fixed speed trap and it's hard to find a specific police car on the road. The K band (24.125GHz) is the most common radar, the thest against that will coming soon.
