8.3 At a distance of 1 km from a 1 MHz radio transmitter the daytime field strength is 200 mV/m. Calculate the field strength 110 km from the transmitter if the ground-wave attenuation is 9 dB greater than the free-space loss. Also calculate the field strength at the same point during the night when there is also a sky wave received. Assume the sky wave to be reflected from a height of 120 km and that the earth is flat.
