The LARG Amateur Radio Projects

      Over the past several years, our Radio Group and its members have undertaken many amateur radio construction projects. We will record for history and hopefully for future members how these were designed, built, tested and used.  Where possible we will include the characteristics and how well they performed.

      We have opened the following pages that describe several of the recent projects.
