I remember the old 10 GHz gunnplexer based radar guns and the “running form” (tuning forks, I speak Bergman) use to calibrate them. I also remember a 10GHz oscillator project in one of the electronic magazines that was called a speed gun “calibrator” kit.

A zippered case with some “files” in it she said. Got home. Not files, but 5 or 6 aluminum tuning forks. All stamped C with the frequency. Each a different octave. Thing is, only one of them is even close to a C. Several C#, one D. If it is a gift, I wonder if it was on purpose.... can you purposely buy tuning forks that are out of tune? What message are you trying to send by sending someone out of tune tuning forks? -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
