Revision as of 09:44, 20 February 2004 by Jeandré du Toit (talk | contribs) (!)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)From the code article:
- In the days when Morse code was widely used, elaborate commercial codes that encoded complete phrases into single words (five-letter groups) were developed, so that telegraphers became conversant with such "words" as BYOXO ("Are you trying to crawl out of it?"), LIOUY ("Why do you not answer my question?"), and AYYLU ("Not clearly coded, repeat more clearly."). The purpose of these codes was to save on cable costs.
Should this be added to the Morse code article?
Probably, but I also put it back into code; it was a good example of the data compression use that wasn't otherwise well covered there; I also gave it a slightly better introduction. --LDC
This article needs to take into account that the international morse code that is used today is not the same as the telegraphic system that Samuel F. B. Morse created (which was based on numbers). The story is to be found in William Pierpoint's The Art And Skill of Radio-Telegraphy. Sorry, I don't have time to write it up right now, maybe later. -ARJ
it would be nice to have american railroad code here as a table as well as international code. If I get to it I'll add it
Just saw this - an anagram of "The Morse code" is "Here comes dots". Well, I found it amusing... -- Jim Regan 03:17 17 Jul 2003 (UTC)
WRTC 2003 eliminated the requirement (made optional) for CW in amateur radio licensing. Did a re-write to incorporate this info, fill in some blanks, and otherwise do some light editing - de NG3K Bill 10:44 25 Jul 2003 (UTC)
Also added a bunch of commonly used CW abbreviations. Bill 18:02 25 Jul 2003 (UTC)
Clarified the difference between prosigns and abbreviations; modified the taxonomy to correspond to this; other tweaks Bill 17:01 26 Jul 2003 (UTC)
Common cw abbreviations should just list the most important few here. Maybe abreviations could have their own article just like Q-codes. Tero 10:34, 16 Nov 2003 (UTC)
Actually, experienced CW operators use abbreviations extensively. Most listed here are quite common and important; could be a separate article, I guess. I would tend to NOT include items that are common abbreviations outside the CW-world however (e.g. QCWA). Bill 22:58, 31 Dec 2003 (UTC)
..--. is given as the code for the exclamation mark, but from some searching it seems there is no official code for it. It's ---. over radio in the USA and Canada according to note 1 at http://homepages.tesco.net/~a.wadsworth/MBcode.htm - Jeandré 2004-02-20t09:48z
