You been hiding out in the wilderness somewhere, in a cave? What do you think it was that started radio in the first place, semaphores? |

Radio's start was a very long time ago, Dick. And I can understand that. However, it is the "for so many years" part of my comment that I find amazing. Here we are so many, many, years later still focused on that. Dwight Stewart (W5NET) http://www.qsl.net/w5net/ |

You been hiding out in the wilderness somewhere, in a cave? What do you think it was that started radio in the first place, semaphores? Phone goes back a long way. Yes, Marconi started out with Morse code, but AM was only a few years behind. There was phone even when people used spark. A circuit patented by Elihu Thomson to keep arc lamps burning was adapted by Prof Duddell FRS to keep a spark going continously for this purpose. This type of transmitter was used by DeForrest in his famous voice coverage of the yacht race from New York harbour. His 'Audion' (triode) was not used in the transmitter as most assume, but in the regenerative receiver used to pick up his spark AM signals on shore. This was because he hadn't figured out that it could be used to amplify, so it predated TRF receivers even. Even before DeForrest, the first transmission of AM over one mile took place on Cobb Island, Maryland, on December 12, 1900. The system was designed by Fessenden, a Canadian whose research was funded by the weather service in the US. He used a spark gap driven by a high frequency alternator, commonly used to produce Morse at several kW of RF back then, but he had an 80 kHz alternator specially made for him by Poulsen, another pioneer in his own right. By exciting the gap with an alternator running at a frequency _above_ audio he was able to make maybe a kW of AM, whereas the Thomson/Dudell design made far less power (a few watts). Unfortunately he had to rely on some sort of rectifier with no amplification or regeneration for the receiver, hence only being able to hear a kW of AM no more than one mile away. Moving on just a couple more years, the earliest published circuits I have seen for continuous wave transmitters, such as those by John Scott- Taggart, show a mic as well as a key. They would, of course, as phone was known for spark transmitters. CW, of course, originally stood for continuous wave in the sense of 'not spark', and was applied to AM as well as Morse. I do use that kind of CW! |

You mean you and Larry boy don't know semaphore Dick? Why that is just plain LAZINESS. You know, when conditions are so bad that you and Larry have to rely on CW and your faithful CW rigs gives up the ghost or conditions get SO bad that CW can't even get through you and Larry could save the world by using semaphore, if you had that skill, that is. __________________________________________________ _____________________ I have to presume by your comment, JJ that you indeed know semaphore. Otherwise, you look stupid when you chastise them for a skill you don't possess. And, of course -- I'm sure it's just plain LAZINESS on your part. What else could it be? Arnie - KT4ST |

Do you doubt that, even without Morse proficiency, they could/would make good hams and could contribute to the service? I dunno. I doubt it though. I wonder if a person who doesn't want to jump through hoops is going to do much of anything that he/she doesn't want to do. Mike, Do you seriously believe that just because someone is not interested in Morse that they could not be interested in, and contribute in valuable ways to, other aspects of ham radio? "Elmering" new hams who are not technical on the technical aspects designing new modes writing useful ham software building networks public service communications emergency/disaster communications "SKYWARN" etc., etc. Just because someone isn't interested in jumping through the Morse hoop, doesn't mean that they are so selfish that they can't/won't contribute. Umm, Carl.... you are here! You have have achieved your goal, at least will be very soon. I'm going to have to assume the reason is to engage in a little gloating? So you're getting what you want on all counts. You really wouldn't have to hear all us PCTA's crying if you didn't want to. In other words, if you want to discuss it, we're here. Lessay we all do what you want, and "just live with it". I guess that means we're supposed to shut up. Then you wouldn't have the fun of discussing it with us, or even telling us to "just live with it". I don't think you would like that very much.. I'm not here to gloat ... I'm here to make sure that newcomers hear the news and aren't overly tainted by being totally awash in PCTAs to the point that they think all hams are that way and decide that ham radio isn't really for them after all, because of a false perception that it's totally populated with the sort of folks that they'd really not like to associate. :-) Carl - wk3c |

Arnie, if learning semaphores had been a licensing requirement for the ARS, I would have learned it along with lots of others, like it or not. I sure wouldn't have sat on my backside for most of my lifetime carping about how 'unnecessary' it all was to make me jump through some "useless" hoop. But of course semaphores have no application to radiocommunications, as I inferred, and JJ knows that, it's just all he could grope around and come up with. No true, what if the sound fails on your ATV setup and you are aboard a sinking vessel? ROTFL |
