Szczepan reminds me of an elderly relative who grew up in the 1920s when electronics was large components on wooden baseboards. They seemed to be developed from mechanical engineering (see if and understand it). It was a challenge to get the relative to understand that any progress had been made since the days of valves. Szczepan seems to have grasped electronics as being the movement of electrons and has muddled that up with air or liquid flow. Initially, I hoped that a polite explanation would help him but after a few weeks I realised that he's not capable of understanding and learning (always assuming that he isn't an Extra Class licensee having a big laugh - which is why I enjoy the humour in his postings). He seems to go around in circles lasting several weeks - I think that the thoughts in some of his recent postings are similar to ones he made a month or more ago. 73, Ian. |

In EM the electricity is like the LIQUID flow ( incompressible and massles). In electronics is GAS flow. Electron gas. Electrons have mass. Do you see the difference between massive GAS and massles LIQUID? S* |

For example, his theory that an antenna acts like a vacuum diode, emitting electrons during one phase of the HF voltage and not taking them back during the next phase, clearly must be wrong. The antenna always has the counterpoise: "A counterpoise which consists of one or more wires in a network insulated from the ground will often reduce loss resistances which might occur when the quarterwave antenna is connected to poorly conducting earth. The counterpoise in the case of a network of several wires acts as a condenser plate with high capacity to earth, with the result of lower loss in the antenna system; for this reason the counterpoise should be fairly close to the ground. [See Fig. 1.] " From: http://www.antennex.com/shack/Dec06/cps.html Joel dipole has the two legs. One of them is the antenna and the second the counterpoise. If it were true, an antenna would be a nonlinear element that would cause intermodulation. As we don't see that happen on a well-designed antenna (it *does* happen when there are bad contacts with diode-effect in the antenna), we know that an antenna by itself cannot be nonlinear and so there cannot be a net flow of electrons. The net flow of electrons is from the counterpoise to end of antenna. S* |

A source of electrons is not required. Transmitters use AC (alternating current) so there is no net flow of electrons. AC is in a transformer. In an antenna is the oscillatory flow of electrons. So there is the net flow of electrons. "It is now known that this device operated by emitting electrons from the single electrode through a combination of field electron emission and thermionic emission.[citation needed] Once liberated, electrons are strongly repelled by the high electric field near the electrode during negative voltage peaks from the oscillating HV output of the Tesla Coil" Do not you know that? S* If that were true, there would be a DC current into a transmitting antenna fed only by HF (AC) current. But of course there is no such DC current. If it were there, it would mean there is nonlinearity in the antenna and there would be severe intermodulation. Always is the "DC" (net electron flow) from the counterpoise to end of an antenna. S* |

S* Hello readers. I've had a busy day on the keyboard and my stubby fingers are rather tired. Anyone else want to try to explain to Szczepan the differences between DC and AC. Shall we simply say that DC = direct current and AC = alternating current and there's a big and significant difference between "direct" and "alternating"? How about direct = flat road alternating = road with hills and valleys? I think that Szczepan may understand "flat", "hills" and "valleys" but I wouldn't care to bet on it. Maybe he'll start to quote from National Geographic. Wonder what would happen if he plugged his computer into a DC supply rather than an AC supply? 73, Ian. |
