The Difference Between : Shortwave Radio Listener (SWL) -and-Amateur Radio Operators (Hams)

[stuff] RHF, I have no bone to pick with you, don't fall victim to trolls here which just wish to "stir up chit", to mask their ignorance ... I had a chit load of ignorance (still do in many areas, including this one!), you don't know until you do ... we are all here on differing levels, we can all get along. When Roy, Cecil and others make statements, I LISTEN, may not understand it, but I listen! :-) I understand; trust me, you have done nothing to either make me like you, or not ... that may or may not come later. Now, this discussion continues ... Warm regards, JS |

Antenna for shortwave reception

Dave wrote: John Smith wrote: wrote: Well, sure, but what does transmitting have to do with anything? We are not talking about transmitting. ... It has EVERYTHING to do with it, it is the same communication, both ways, simply in reverse ... like I have stated before, the exact same laws of physics governing the antenna makes it equally acceptable to both transmitting and receiving. The same pattern seen in the signal transmitted will be seen in the signal(s) received. Your argument is the equivalent to arguing that a car designed to go forward would not be acceptable when backing up ... simply ridiculous! Regards, JS How does one transmit MW with a ferrite bar antenna? An MW ferrite antenna: Transmit antenna rating poor. Coffee mug warmer rating excellent. -- Telamon Ventura, California |

Shortwave Radio Listener (SWL) Antennas -versus- Amateur Radio Antennas

John Smith wrote: Telamon wrote: ... Yeah but we don't care about transmitting goofball, we care about receiving and so that statement "A random wire (e.g. inverted L) transmits nicely if you use a tuner at the feed point" by Dave is relevant where you are not. You ridiculous fool. You are the most complete brain dead example of a sub-human which has ever been presented to me ... You dumb twit. We don't care about transmitting. Receiving is EQUALLY as important as the transmitting element in the above. Again you dumb twit, we don't care about transmitting. Or, to explain it to the necessary point, for a mental midget, such as yourself: "If the signal being transmitted is low power, or there are bad conditions, and, perhaps, the guy is in Australia, I'd better have the "best" antenna possible. However, if I am receiving the "50,000 watt atmosphere burner", 50 miles away, a rusty coat-hanger, most likely, would work ..." You are one funny guy I'll give you that. However, you mileage may vary with you "magical antenna logic!" grin The only magic around here is spouted by you. Your experience is "magically" different than anyone else's and your antenna theory is simplistic at best not to mention the great job you do of putting words in peoples mouthes never spoken but what else can we expect from the comprehension impaired. I'll tell you what is "magical" and that's the conversations you seem to have in your head before you post. You hit me as a guy attempting to pass off "magical physics" to kindergarten-ers; but then, even that is, most likely, a challenge for you ... sad, so very, very sad ... :-( Yeah, very sad of you to keep plonking and then continue to read me. What a goofball. -- Telamon Ventura, California |

The advantage of a physical height (antenna length) between 180 and 215 degrees (see previous post regarding the magic number being around 195 degrees) is improved take-off angle and reduced skywave-groundwave interaction, not dramatic nearfield voltage increases. Regarding Mr. Smith's comments above my experience and others is the opposite. 5/8 is a much better performing antenna than a 1/2 wave for local VHF and UHF communications. Well worth the effort to build a 5/8 wave antenna over a 1/2 wave. The 5/8 had some kind of series load coil part way up the whip where the 1/2 wave match/compensation was done at the base so the whip was solid. Sorry I can't more specific then that as those experiments were many years ago. Mr. Smith is still lost in space. 5/8 wavelength antennas do not require a ground plane, do they? |

This is very similar to my hobby (what I enjoy). I can't believe they pay me to do this. |

Now, let me give you a mechanical example, so those willing and/or able may grasp the concept, in fact, let me give you a couple: 1) The neighbors light is shining in my window(s), it is too bright too sleep--I place a thick blanket over the window--WAALAA, "masked" the problem! 2) The neighbors stereo is too loud. I plug my ears, again, WAALAAA, problem fixed! 3) [add your own example here] telemundo is an argumentative idiot with a poor working knowledge of what discussions he engages in ... :-( But then, if you don't possess the knowledge/experience to be able to realize this, no one can blame you for being fooled ... later. Regards, JS Telemundo is a subsidiary of General Electric. Your analogies don't hold up. You cannot transmit with a Beveridge and you cannot transmit with a ferrite loop. |
