To be a radio proficient guy, was my childhood dream. From being very little I knew that radio is a device which can speak and sing in multiple human voices. And consists of many electronic components.
Being 11 month old I took appart my father's transistor radio, branded SELGA. After that a few months later my father luckyly bought an identical one. Being 2 or 3 years old I took appart RIGONDA vacuum tube radio, without being hurt. This experience made be acquintat with the parts of radio, and a choice of my future field of research. yes, thre were a lot of other electronics in our home, which I was eager to take appart, however I did not do it. And other taskes appeared for me.
For example I was going to an kindergarden, which I hated, and then to elementary schooly, which I admired sometime, and to music school where I was very reluctant to learn playing piano by notes. However with a help of radio and tape recorders I could pick any tune on a piano, being 10 years old.
To make this story short - I started my radio class experience after being 10 years old.
