Abstract
SINCE 1925, I have made observations upon the signal strength of KDKA in Pittsburg. The observing station at Morgantown, West Virginia, is sixty miles due south of KDKA. My results are in complete agreement with the discoveries of Prof. Ivo Ranzi1, provided I assume that the 309-metre wave from KDKA behaves like a 100-metre wave in so far as tho E layer is concerned.
