Hello from Kiev (Kyiv), Ukraine

Former Soviet Union countries are interesting in many respects.
With radar and lidar the police in Ukraine mostly buy American Lidar guns.
The radar guns come from the USA, the European Union, and from Russia.
There is one gun from Russia that uses a laser that is 100 nm higher;
it is too expensive for jammer manufacturers to buy diodes of that wavelength.
So leave your jammer home when driving through Russia :-)
