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. |
I
give my call/QRP with 5-watts running by my IC-718. Only "QRZ?"
I have received. After several unsuccessful attempts to do QSO I
increase my power to 10 watts. The Ukrainian station, operator Gene,
gave me 599... BUT! The stations did not hear me on 5 watts, however when I run 10 watts,
I have received 579 and 589. |
