over the last 13 years I have developed a family of state-of-the-art ARDF-receivers and -transmitters, and I have published the results on this website. I have supported several hundred YLs and OMS with PCBs and parts for these projects. That was a lot of fun, but also very time-consuming. I wanted to have more time for my own projects, and therefore since 2011 I do not sell PCBs and parts for my ARDF-projects any more.
But my website is still up, and I maintain it regularly. And thanks to the intiative of some ARDF friends all parts and PCBs are still available, see here.
