I wonder what kind of sensitivity the radar must have for scientific purposes here (attempting to detect the alleged ether). I recall from many years back that at 40 mhz (40 X 10^6 hz) the old police radars gave a doppler effect signal of 7 hz per mile per hour. Thus, a vehicle traveling at 50 mph would give a doppler signal of 7 X 50 = 350 hz. Do you (or anyone else) know if such doppler radars on aeroplanes tests have been done? As a electronic engineer, the idea struck me as very interesting. Art

The capability of MichelsonMorley apparatus so greatly exceeded what would be required to detect the "expected" ether-wind that it is really a moot point. All kinds of communication and navigation devices that we take for granted would be malfunctioning rignt now if through some experimental error the signal was missed by the MMX. The experiment has been repeated many times. A few notable examples about mid-page: http://en.wikipedia.org/wiki/MichelsonMorley_experiment Sue... > > Art

And its end speed can be calculated by measuring the fluctuating weight of a test mass. Motion is detectable at its onset and its end. Mitch Raemsch

As an "Electrical Engineer" with a major in microprocessor based design and RF design methinks your aren't anything at all. tom
