Ground is something you stand on, but in an electrical sense, the meaning is much less clear. When it comes to broadcasters and ground, things get really confused. We drive rods into the earth, but why? Let’s take a look at whether any of this makes sense, and what theory tells us about “ground”, and if it exists in any sensible way at all. We’ll talk about DC grounds, RF grounds, and even about gravity.

Join us Wednesday, September 20th, 2017 at noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. Chapter 36 will provide pizza for this great lunch ‘n’ learn session.
