Re: Interesting speed test
I hate to call you out, but to my recollection CW and Morse Code are the same thing. Maybe you are talking about modulated CW vs traditional? Modulated being where you can hear the beeps without the need to modulate it on the receive end.

Re: Interesting speed test
You said that text messaging doesn't rely on phrases. But if you really think about it, any person that spends long enough typing, or text messaging will eventually stop thinking in letter and start thinking in words, then in sentences. Reading is the same, you do not look at each word and sound them out slowly letter by letter do you? further you do not stop and think about each word as you read your text either do you? it comes down to the way we process information, in either case comes down to the same thing, sentences and the ideas they represent.
just wanted to throw that out there for consideration, DE KI4URQ |

Re: Interesting speed test
That's fine I just don't want there to be any confusion. There is a wide following for voice and CW. I personally am looking into digital.

Looking at the chart for QWERTY: Have you ever met anyone who could type 150 WPM on anything? I wonder what the world speed record is. As you well know, 75 WPM is rare. Ask around where you work. And, as others have stated: When you read, you decode the information a word at a time, not a single letter at a time. We're apples to apples here. Quote:
Compare CW to AM (Amplitude Modulation) or FM (Frequency Modulation), where instead of having an unchanging RF carrier (that is switched on and off) you vary some parameter of the carrier (amplitude or frequency). CW is what most Hams will call Morse code, although technically inaccurate they are used interchangeable. Don PS: The "other life" Al S. refers to is that I write about digital communications for a ham radio magazine. That's why Shannon is a hero of mine, and why I know a little about coding theory and modulation types. Anthony, let me know if you have any questions. |
Re: Interesting speed test
I get the feeling that in all of the debate here between Morse Code vs. texting some might be overlooking the fundamental difference. Texting, emailing, instant messaging, Twittering, or whatever you want to call sending the bits that make up an electronic message requires a cell phone or some other sort of electronic device. Morse Code does not. You can send Morse Code with a flashlight, a stick and a pot, or even your car horn.
Let’s say you are a ship captain being held hostage in a lifeboat by some pirates and the US Navy is nearby. Maybe you could get a message to the Navy with a signal mirror or piece of a reflective Mylar emergency blanket both of which are standard equipment in a lifeboat. Maybe if the Navy knew that you knew Morse Code they could some how get a covert message to you using say a flashing light or a horn or a Navy Seal tapping on the bottom of the life boat hull. Seems to me that it sure would be nice to know when the Navy snipers plan to take their shot at the pirates so you can hit the deck. My point is, regardless of speed, being able to send a message to someone at a distance has always and will always be a useful thing and a cell phone or computer isn’t always the best option or even available. Morse Code has been a standard messaging system for a long time and will continue to be for a long time to come. Those that seem to think Morse Code is an old dead useless technology might need to rethink their assessment. I wonder how the “speed test” would have gone if the two ham operators had used a cell phone as well but as a flashlight and their hand to cover and uncover the screen instead to send Morse Code? Oh, and for whoever wondered if there is a Morse Code IPhone App, yes there is one. |

The idea of the Leno test was to demonstrate that: "CW and old guys rule!" While these two things may be true, competing against a known-to-be-slow multi-tap cellphone is a copout. The demonstration had the CW going at under 30 wpm because that was as fast as the receiving CWer could write legibly. http://www.marc.on.ca/marc/hamradio/hr_cw_vs_sms.asp Here is a blackberry going at 75 wpm: http://www.youtube.com/watch?v=Egie4ApwoUg&fmt=18 But since you want to choose your keyer, then I would like to choose my own keyboard and person, I would probably pick a bluetooth DVORAK keyboard, any bluetooth enabled cellphone and someone like Barbara Blackburn and make it a reasonable length message: Mrs. Barbara Blackburn of Salem, Oregon maintained a speed of 150 wpm for 50 min (37,500 key strokes) and attained a speed of 170 wpm using the Dvorak Simplified Keyboard (DSK) system. Her top speed was recorded at 212 wpm. Source: Norris McWhirter, ed. (1985), THE GUINNESS BOOK OF WORLD RECORDS, 23rd US edition, New York: Sterling Publishing Co., Inc. But if you really want speed in person to person message communication, how about 637 wpm? http://members.fortunecity.com/talker2/talk.htm Steve Woodmore can speak at 637 words per minute, which is 10.25 words per second. The common practical purpose of sending a text message is send and forget, and not to require a person at the other end to spend immediate time and mental energy decoding it at the other end: I think it is generally accepted that most sighted people can read text much faster than they can learn to decode CW. I do not expect to see a resurgence of people going to the telegram office or their local ham to send messages rather than just pulling out their cellphone. But I could be wrong. I think it is generally accepted that the need for CW still exists but is waning a bit. How else would you explain the removal of CW testing for most if not all US licenses? The cynic in me would guess that the radio retailers want to sell more radios to people that are too lazy to learn some proficiency in the CW language and the retailers lobbied the FCC. The Elmers who would generally like to see CW proficiency remain a requirement lost out to the retailers. Part of it could also be for the same reason teachers in more advanced math classes let students use calculators: because using machines instead of your brain to do more basic tasks frees the mind to concentrate on other things. Do you use a calculator or would you force yourself to compute long series of mathematical operations in your head? |

Can't really prove it either way, can you? I'm not saying that this isn't true, I'm saying that it's kind of hard to guess intent from the results. (And yes, I read all of the <G14> debate, and I prefer an alternative explanation to the one above.) Quote:

Re: Interesting speed test
wow, In a way I'm not surprised, when you think about it, someone who is experienced can make a series of dots, and dashes faster than the time it would take to type and transmit a message via sms...

Re: Interesting speed test
As we all know, there are far faster methods of sending messages than Morse code, or even SMS for that matter. Anyone have a gigabit LAN? And boomergeek has designed network equipment for even faster messaging.
Considering that, the contention here is not that CW is fast. It's faster than the world-champion texters on the Leno show, compared to two moderately proficient Hams. But, as boomergeek stated, it was contrived. Please.:p It was an interesting discussion, but now it's getting a little contentious for me. |

Maybe I'm all wet: Any qwerty texters out there impressed with texting speed races against 12 key keypads?
