I go back to before the start of the national 55-mph speed limit a half-century ago. Interested in electronics since a kid, I've been a licensed ham for 45-years and have built countless circuits of one form or another. Always interested in microwave tech but never really had the proper build and test equipment to do microwave work. Own a good number of traffic radar units and a large box full of old radar detectors which I sometimes cannibalize to produce other things. Retired officer from the Army Reserve, retired big city police officer, and after all that I managed to retire as an associate college professor. So... I'm very long in the tooth. Hate to see that this forum goes largely unused these days, especially since I now have nothing but time to read and discuss electronics. Oh, I never had a traffic ticket in a lifetime of high-mileage driving. Maybe I'll get one today.
