Radio frequency energy is magic. Black magic. It is a little-known fact* that Alexander Bell STOLE the invention of the telephone. The first guy didn’t protest, however, because he had been BURNED AS A WITCH!!!
I had a piece of test equipment fail on me today. It was reading anywhere from -30dB to -70dB down from the levels it should have. I figured out that the cable between one part and another was broken. There was no physical contact at all, and the signal was still passing – though it was greatly attenuated at lower frequencies. There was NO physical connection and the signal was still going through at a useful level! Witchcraft I tell you. Repairing the cable made it work all better again.
*little-known because I just made it up.
