PRINCIPLES OF RADIO COMMUNICATIONS
Developing an understanding of radio communications begins with the
comprehension of basic electromagnetic radiation.
Radio waves belong to the electromagnetic radiation family, which includes
x-ray, ultraviolet, and visible light — forms of energy we use every day. Much
like the gentle waves that form when a stone is tossed into a still lake, radio
signals radiate outward, or propagate, from a transmitting antenna.
However, unlike water waves, radio waves propagate at the speed of light.
Radio wave amplitude, or strength, can be visualized as its height —
the distance between its peak and its lowest point. Amplitude, which is
measured in volts, is usually expressed in terms of an average value called
root-mean-square, or RMS.

in my free time i like writing some texts in english, this is so cool. when i go home, after hard day at school, i'm starting doing my homework, and i can't wait, when i can write the text in english, excuse my tautology. when my friends go for a walk and have fun, i'm writing the texts, like this; i can write texts for 10 hours. i could built a perfect card castles or i could create incredible domino rally. but instead of this i'm naturally create the sentences and make a texts of them in english of course. sometimes i going to a street and take some notes in my notepad, about everything, like what humans prefer to do. usually they do nothing, just pretending to busy with something. i have a second little hobby, which i do then i don't write some lyrics - it's collecting bugs and some insects. i just go to the forest and put the bottle traps, after i use special technique to perpetuate them. and also i love a dreaming.
