SC,
Morris Code -plus- Continuous Wave (CW) Radio Transmission -and- Semaphore Signals ? Do They Defining Amateur Radio ? - - - The Times They Are A Changing ! While I can admire and respect an Amateur {HAM} Radio Operator for Mastering Morris Code (CW). Morris Code in and of itself does not define the Amateur Radio Service. Morris Code http://en.wikipedia.org/wiki/Morse_code Continuous Wave (CW) Radio Transmission 'process' in and of itself does not define the Amateur Radio Service. http://en.wikipedia.org/wiki/Continuous_wave The Amateur Radio Service is Greater than both Morris Code and Continuous Wave (CW) Radio Transmission - IMHO ~ RHF Boy Scout Merit Badge Requirements - "RADIO" http://www.meritbadge.com/mb/093.htm At one time when I was a very young boy nd a Boy Scout I Learned to Send and Receive Morris Code at about 5WPM -but- Then I also learned to use Flags to Send Hand-Flag "Semaphore" Signals Too ! http://en.wikipedia.org/wiki/Semaphore_(communication) Neither the ability to use Morris Code or the Semaphone Flags to Communicate 'defined' Being A Boy Scout. just an old boy scout at heart ~ RHF |

I thought Id mention that one of the things that was overlooked in the
Titantic disccusion is the CW was not invovled it was spark gap used in that Morse encoded spark Actually that is not correct. Within the original meaning of CW, the Titanic used a CW transmitter. It was not a spark transmitter, the rf energy was produced by an alternator which provided 'continuous' rf power, hence CW. The output was not a damped wave that a spark transmitter would produce, but an interrupted 'continuous wave' (from the alternator). Regards Jeff |

Like your link says, it's MORSE code, as in Samuel F. B. Morse. Who's
Morris? Scott RHF wrote: SC, Morris Code -plus- Continuous Wave (CW) Radio Transmission -and- Semaphore Signals ? Do They Defining Amateur Radio ? - - - The Times They Are A Changing !

Palmer" wrote: Assuming some weird contrived scenario where I had the equipment to send CW but not phone, it would depend what frequencies it worked on. I think this is the nature of the premise on which the original post was based. Compare it to a similar situation, where a film camera user is debating a digital camera user: "If you came upon a drowning man, and you had to choose whether to save him or photograph his demise, what kind of film would you use?" Getting rid of CW is like choosing the kind of film. Ham radio is drowning and the anti-code hams want us to think tossing it bricks will make it float better. Dumbing things down is never an improvement. SC |

Sam's original equipment used ink and scrolling paper to record the dots and dashes because he didn't think an ordinary human being could distinguish between the sound of the dots and the sound of the dashes. He was wrong. Human operators quickly discovered that they could distinguish the difference between the down clicks and up clicks and therefore distinguish the dots from the dashes. It is true that Sam's "American" Morse was different from "International" Morse in about a dozen characters but both used dots and dashes. Still, more characters were alike than were different. The term "lid" may have originated from newbie Morse operators laying a lid on top of the relay receiver to make it easier to distinguish the dots from the dashes. -- 73, Cecil http://www.qsl.net/w5dxp |
