When I point my 'Pocket Radar Speed Gun' http://www.krunker.com/2009/12/29/pocket-radar-the-portable-speed-gun/ at my Panasonic Plasma TV it shows that the TV is doing 54mph in standard definition and either 54 or 108mph when displaying an image in HD mode. I suspect that that the unit is seeing the TV plasma being established at some high frequency. This frequency will pass straight through the gun electronics and appear as a doppler sideband related to the speed that I am observing. It should be possible to work out the high voltage power supply frequency of my TV knowing the frequency of the pocket radar which is 24.125 GHz. Any ideas anybody? [*-)]
