radio fadeout

radio fadeout

[′rād·ē·ō ′fād‚au̇t] (communications) Increased absorption of radio waves passing through the lower layers of the ionosphere due to a sudden and abnormal increase in ionization in these regions; signals at receivers then fade out or disappear. Also known as fadeout.

fadeout

Fadeout due to interference between waves which have traveled different distance as well as due to disturbed ionosphere.A type of fading in which the received signal strength is reduced to a value below the noise level of the receiver. The most common cause of fadeout is a disturbed ionosphere. Also called a radio fadeout, Dellinger effect, or Mögel-Dellinger effect.
