Classification of all YU1LM /QRP SDR designs

   I received several E-mails with questions about choice adequate types SDR designs. I am professional R&D and as professional designer I have always a limit to finish designs to dead time line. As HAM I left my imaginations to make test in many directions and results are different types of designs for the same purpose. This article with classification of all YU1LM/QRP SDR designs is my little help for homebrew builder to make correct choice according to their specific requirements or some other criteria.
