I always had one with me. In the past I built quite a few from scratch. Now I have bunch of old Bel9xxs. They are the best! And old Cobras or BearFinders still at home in my car, just for kicks.
For me this is just like ham radio watch, only in MicroWave. This is exactly why law still allow us to have them, just to receive whatever in the air, with no ill intent.
I got across thread about no LO-leak type of radars, I thought I can share thing or two, just for general education of the public.
