Excerpt from A Study of Radio Signal Fading 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.

Excerpt from Historical Survey of Fading at Medium and High Radio Frequencies An attempt was made by Dellinger, Whittemore, and Kruse 1923] to correlate fading with meteorological data. They concluded that fading is caused by variations of absorption in the ionosphere. Pickard 1924] noted the variation in fading from day to night. His experimentation at MF showed that the fading is essentially uncorrelated for receiver separations of about 600 meters. Many field strength records from quiet to highly disturbed conditions are illustrated. He hypothesized that fading is caused by changing absorption and multipath interference, and suggested an influence of the earth's magnetic field. Appleton and Barnett [1925a] also indicated that fading at may be due to interference between ground and ionospheric rays. They performed a frequency change experiment and concluded the reflecting layer to be at about 80 km. Eckersley [1925] suggested that more than two rays (i. E. Multiple ionosphere - surface reflections) must be considered. The existence of the ionosphere was verified by Appleton and Barnett 19z5b] who showed that the components causing fading were in a vertical plane. They also found that during a solar eclipse, fading took on a nighttime character. They suggested magneto - ionic effects in the ionosphere [19250] Because of the difference in fading during the day and night, Appleton and Barnett 1926] concluded that fading was caused by variability of the rays deviated by the upper atmosphere, and not by a change in the frequency of the transmitter. Their results indicated a diurnal change in layer height. Hulburt [1926] attributed fast fading to mode interference and slow fading to cloud motion.

In 1901 the National Bureau of Standards (NBS) was founded to provide standard weights and measures and to be the national physical laboratory for the United States of America. The NBS conducted a lot of research in the fields of science and technology which were reported as "Scientific Papers." In 1988 the NBS became what we know now; the National Institute of Standards and Technology (NIST). This is one of those documents written by employees of the NBS.
