Nonlinear Propagation of Radio- Wave in Ionosphere: by Igor Grigorov, VA3ZNW

There are a lot of interesting phenomena at ionosphere propagation of radio-wave (for example, remember LDE!). One of such phenomenon is nonlinear propagation of radio- wave in ionosphere. What is it this effect? A very exactly description of the phenomenon was given by Vladislav, RX3ALL, at a message sent by him in the RU- QRP- C forum on December 19, 2005.
