electromagnetic transmission power relativistic effects

Hi,For a radio transmitter that is transmitting a 1MHz sine wave at 1kW power into free space, and then a 1MHz receiver is turned on 1 km away, which draws 1uW? of power from the transmitted wave, will the transmitting power supply increase by 1uW at the time that the receiver is turned on or at a later time proportional to the distance to the receiver? I was wondering about this because from some interpretations of quantum mechanics it seems that the transmitter power supply would increase its power draw by 1uW at the exact time the receiver turns on, but this should be relatively easy to test if there is an actual delay.cheers,Jamie--- Posted via news:// - Complaints to ---

Natch, you'll just get some signal attenuation right behind the receiver. - YD.
