Unless you count disagreeing with him and proving him wrong as "being mean", you've been nothing but nice to him. so I'll try to meet him halfway with a Morse code topic. His definition of meeting halfway is that you agree with him 100%. So maybe we can ressurect this old one... I hear lots of Hams declare that Morse code is a binary mode. It is most certainly not. Depends how you define "binary". Let us look at the situation. Is the Dit a "0"? No. Is the Dah a "1"? No. Is the space between characters a "0"? and the Dih a "1"? Oh wait, what is the Dah then? Oh, and what about the space between words? Key up is "0". Key down is "1". Also known as "space" and "mark", respectively. It isn't binary, Depends on how you define "binary". and the way our noodles process it isn't binary. Different subject. It's not binary. Most Morse operators with any skill (that excludes Len) process a complete character as one "sound". "didahdidit" is recognized as "L", in the same way that when you hear the word "cat", you think of the animal. The Morse operator does not think in terms of dits and dahs any more than a person thinks in terms of the consonant and vowel sounds (phonemes) making up "cat". Of course *really* skilled Morse ops hear entire words as units of sound. And at some level, they begin to think in Morse, just as fluent speakers of a language think in that language. Of course Len wouldn't know about that... 73 de Jim, N2EY |

All the timing was in terms of the length of a single "dit." As far as I know, Morse code did not "become digital" until some people wanted to make it look as if it was more advanced than it is. Until then it was as you describe. - Mike KB3EIA - |

Until then | it was as you describe. You're confusing your terms now. Digital and binary are related, but not the same. This defintion of `digital data' http://www.answers.com/main/ntquery?...87736&method=6 definately fits Morse code, both at the `on' and `off' level and at the `dit' `dah' `short space' `medium space' `long space' level. Digital also means `having to do with fingers', and Morse code is usually sent using one's fingers ... Of course, the terms digital and binary didn't really become commonly used until computers did. Considering that Morse code was born in 1832 or so, it's not surprising that people weren't thinking of it in computer terms for a while. Ultimately, terms are getting confused all over the place. The terms CW and Morse code are used interchangably, when it's really more accurate to say that CW is to Morse code as RTTY is to Baudot. But ultimately it doesn't matter, because however you define it, people use it to talk to each other and it works. -- Doug McLaren, , AD5RH This is a test of the emergency .signature program.

Two states. Binary. This is not something that can be rationally denied.

Both views are correct, so a claim that one view is wrong is incorrect. Morse code gives you a way of turning a series of binary states (on or off) into text. ASCII, EBCDIC, BAUDOT, UTF-8 and oodles of others do the same thing. Morse code is just as `binary' as they are, but it just happens to be more suited to human use. Ultimately, it's a pointless argument, because whatever Morse code is and is not, people use it, and they agree on what sequences indicate what letters (of course, this wasn't always the case, but that's another story), and that's pretty much all that's needed for it to work, and so on that note I'll attempt to remove myself from the discussion. -- Doug McLaren, Math illiteracy affects 8 out of every 5 people. |
