We have some experiments on our forum since I've opened this thread. We found that our russian Lidar works on 2,22kHz and also that none of detectors can take this frequency, except V1... but I surmise it in non stabilized detection. In addition my tests with ZR3 leads to conclution that it doesn't works above 600Hz. With a help of GOL info about Traffipatrol XR we realised that it works from 0,4 to 3,2kHz roughly... So, the question: is it true that LI and Anti-Laser can jam on 3,2kHz and if it so - on 2,22kHz too?
