DF1FO's  ARDF-Receivers         

Dear ARDF-Friends, over the last 6 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. It was a lot of fun, but also very time-consuming. I would like to have more time for my own projects, and therefore I do not sell PCBs and parts for my ARDF-projects any more. I will keep my website online for a while.
