Pedro Chicherchio

I am 62yo, working as System Analyst from 1974. I got the passion for electronics and radio from my grand father and from my father, and I learned so much with everyone of them. Only in 2011 I got time in my life to devote myself to the HAM hobby, and my main motivator is the technical part of amateur radio. I'm still an amateur radio and electronics fan, but because of my QTH, I need a little more research on antennas and noise filters.

Then, you must enter the dimensions for your house:

largura = height, comprimento = width, altura = tall

This is a sample of the QSL Card produced:
