I'm astonished all you OTs are missing the truth! Don't you recall the endless harangues about kc, Mc, etc., being nonsense? It's cycles PER SECOND! So the correct for thousands of cycles per second is kc/s, millions is Mc/s, etc.
Leaving the "/s" off in a magazine article would result in a flood of snail-mail-to-the-editor about the idiot that didn't use the correct term. What is ironic, IMO, is that Hertz likely would have been crowned the "father of radio" if he had understood the effect of the very parameter named after him - frequency - on electromagnetic waves. Hertz showed that electromagnetic waves were heavily attenuated by just about anything and completely blocked with a thin sheet of metal. Obviously they were useless for long distance communications. It took a fellow who also didn't know about the effects of frequency to tinker around and discover, to his everlasting delight, that his waves they tended to travel much farther than Mr. Hertz' waves. It was years later before anyone understood the difference was that young Mr. Marconi was dealing with frequencies in the range of 20 to 50 Kc/s (Hz) where Hertz had been working in the range of about 50 to 100 Mc/s (MHz). Mr. Marconi has my admiration as much for his tenacity and dedication to questioning what the experts knew as for his genius in improving and creating new devices. He often recognized publicly that was just "playing around" doing something all the experts knew was impossible experimenting with "Hertzian waves". Accordingly Marconi often referred to himself as the first "Radio Amateur". The tradition of trying things that interest us, especially if it's something the "experts" think is a waste of resources and time is something I hope we Radio Amateurs never let slip away from us. After all, it was Radio Amateurs "wasting their time" who discovered that longer waves aren't always better for DX, as Marconi and his contemporaries had decided, and discovered the almost magical propagation of signals in the "short wave" region above 2 Mc/s. So I do agree with the thesis. If we can have a unit called the Hertz, where is a unit called the Marconi and where would it end? Wouldn't a nice statue be more appropriate ;-) Ron AC7AC -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Don Wilhelm Sent: Monday, December 08, 2008 4:59 AM To: Elecraft Reflector Subject: Re: [Elecraft] Units Wait just a minute. Those old units should be "kc" and "Mc" to be correct. The proper units multiplier designations and their abbreviations are: kilo = k = 1000 Mega = M = 1,000,000 milli = m = .001 That is why the capitalization/non-capitalization of "M/m" is so important. 73, Don W3FPR Tom wrote: > On Sun, 07 Dec 2008 14:32:28 -0500, you wrote: > > >> Wait just a minute here Mike!! >> >> What happened to MC and KC? >> >> If your on 20 meters and move to avoid the QRM did you go up 2 Kay >> Cee's or 2 >> Kilo Hertz's .
