It looks like Mattia built this receiver way back in 1995. The tuning indicator is very cool, and I had not seen a similar indicator before (could this be a way for us to escape the clutches of the San Jian counters or the Arduinos?) The Italian ham magazine articles are great, and you can follow the rig description even if you can&#8217;t read the Italian. The pictures in in the attached drive are also very good.<\/p>\n<p>I have been in touch with Mattia via YouTube: He reports that he has done other electronic projects, but he considers this to be the most interesting. He does not have a ham license &#8212; he has a Shortwave Listener license. His father was a ham: I3ZQG.<\/p>\n<p>This is one of the rare cases in which the builder should &#8212; I think &#8212; be issued his ham licence purely on the basis of this build.
