The Science of Ham Radio: Bringing Ham Radio to the People

摘要

Recently, I received an invitation to participate in a demonstration at a local science museum. Although the timing was awkward -the weekend after Field Day-I decided this was an opportunity I could not refuse: The invitation notice mentioned they anticipated an audience of 3,000 guests during the two-day event. This was a double treat for me, since I have never visited the science center before. So, I convinced my friend Dennis Kidder, W6DQ, and a non-ham friend and physics model-maker, Walter Clark, to join me in the "Meet the Makers" event at the Discovery Science Center (nicknamed "The Cube") in Santa Ana, California (fig. 1). According to a science center news release, "Meet the Makers" coincided with the science center's current exhibition: "Da Vinci-The Genius." The exhibit is the most complete and comprehensive traveling exhibition ever created on Leonardo da Vinci.
