In 1975, when I received my HAM RADIO license,I always had a particular
interest for Homebrew. In fact, apart from some measurement instrument, all the
Radio equipment in my station are strictly HOMEMADE. On these pages you
will find some of my projects + the HF TRANSCEIVER born from the cooperation
with Pierluigi I6WJB.
