Inhaltsangabe

Excerpt from A Study of Radio Signal Fading<br/><br/>As a typical example of fading, suppose that a radio laboratory at, Washington were listening to a station in Massachusetts. This station may call and be received with satisfactory intensity, may begin the, preamble of the message, and then, as the text is begun, the signals may rapidly increase in intensity, until within a few seconds they may be heard throughout an ordinary room. Then, as the transmission proceeds, the signals may become rapidly weaker until they are unreadable, or even entirely inandi ble by the time the end of the message is reached. By the time the station has finished the transmission of the message the signals may again be received at a satisfactory intensity. It can readily be seen that such an occurrence makes communication very diin cult and may occasion many repetitions of transmissions which, if the maximum intensity were maintained, could be received without difficulty at the first attempt.
