About this website

Hello, SP6GK is my amateur radio callsign and I'm interested in electronics engineering, especially analog and RF design. Beside modern electronics I collect and restore tube radios.
I also like music from 1920/30/40s especially played on the theatre organ. The goal of this simple website is sharing my electronics project as well as preserving and presenting information that I have gathered about theatre organs and vintage radios.

All of my projects published here are open source. Feel free to use them for your own, modify them and distribute modified versions if you want.
The only one rule is that I prohibit selling them without attribution.
