This book details the collaborative investigation of several physicists and radio operators to better understand radio signal fading, an unpredictable phenomenon which results in the fluctuating intensity of radio signals, primarily those of high frequency. The investigation took place over a series of tests conducted between 1920 and 1921, primarily in the northeastern United States. The physicists and radio operators involved were able to analyze weather conditions and atmospheric conditions to form conclusions as to the causes of fading.
