My name is Tobias and I am an RF/Elecctronics engineer and radio amateur. This webpage is devoted to my collection of HP equipment, its repair and maintenance, and to some other things (mostly) related to electronics.

My interests lie in the field of telecommunications engineering (especially RF, analogue and DSP) and in mathematics (also with Matlab and Simulink). I have done many of the lab experiments I show here at the Lucerne University where I studied and worked previously, or in some spare time at my current employer which is Albis Technologies Ltd, a company which develops telecom devices and does a lot of RF engineering.

Because I want my pages to be useful for as many ham colleagues as possible, I try to write most things in english, but if you want to contact me or comment things, feel free to write in german if you wish 😀
