Hey everyone,
my name is Sebastian, I am 24 years young and I am - just like most of you - an electronics enthusiast. I love RF and RF related topics. My username, KF5OBS,is my amateur radio call-sign. I build most of my amateur radio gear myself and I am not afraid of DIY projects with very high frequencies. My highest accomplishment is the 10 GHz amateur radio band so far.
I try to learn as much as I can and my favorite method is 'try and error'. When I started building electronics circuits at age 7, there was no literature and no internet available to me. My first experiment was to find out what happens if one connects a LED directly to a 9 V battery without a resistor. Why did I do it? Well, a red box warning in the manual for my electronics kits said not to do it, I wanted to know why. I ended up breaking both LEDs in the kit and was pretty sad that I could no longer experiment. A friend of my mum, who is an electronics engineer, laughed and brought me Red, Green, and Yellow LEDs - a hundred of each. After he also introduced me to a soldering iron and perforated PC Board, I was unstoppable. I found thousands of ways how not to do it and how to break a lot of components. That was the best form of learning for me.
