And I always thought doppler shift was Burkland going past you at 450

Mike, come on, now, Ya'll are pullin' my leg, aint ya? My N router runs it's
carrier at either 2.4 GHz or 5 GHz (maybe it is 5.8 GHz) So the lambda for the
frequency (I think that is the tern for length of the wave) would be at 2.4
GHZ is 0.40982 ft. At 70 mph the distance in on elambda is 0.000000004 ft. Add
that to the base lambda to see the frequency shift or doppler effect and the
new wave length in ft is 0.40982004 ft. The frequency shift is so small that
it barely moves, even out to at least 4 decimal places. Now, I gotta be
honest. I really do not know what I am doing here with this, so have you
calculated the actual doppler shift to see how much of a change it really is?
Was anything else going on at the same time?Or is it like usual, I have my
head up my anal orifice, lol... mayf ______________________________ drmayf
