DF1FO's  ARDF-Receivers         

Welcome to my ARDF-receiver website!
Here you will find up-to-date information about my processor-controlled ARDF-receivers.
Please note:  
these are homebrew-projects.
 
Dear ARDF-Friends,

over the last 12 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.
If you have questions or comments please send me an Email:
