For years I have been working as a test project manager, but my oldest hobby, which spends most of my time and money, was all kinds of games with the radio.
Starting from the construction of simple receivers at the time when the diode was a serious element, through several-transistor receiving circuits and more and more complex applications, I became acquainted with electronics and its applications.
Since 1989 I have been a member of the Polish Ham Radio Association and I have a first category license allowing contacts via radio around the world.
